Understanding the Basics of Airflow
Your air conditioning traditionally uses ductwork to transfer cool air from one room to another. As long as air flows properly through the system, you’ll enjoy cool air, no matter what room you’re in. In addition, proper airflow means your air conditioning system doesn’t have to work as hard to cool off your home, helping you save on energy bills. For these reasons and more, many people want to know how to increase airflow in their AC systems.
Practical Steps To Increase Airflow in Your AC
Ensuring you have proper airflow throughout your property doesn’t have to be difficult. The following are some actionable steps you can take to increase airflow in your AC more effectively:
- Change Filters Regularly: A clogged filter restricts airflow, forcing your air conditioning to work harder, leading to increased wear and tear. Changing your air filter regularly ensures cool air can flow freely, improving your system’s efficiency and longevity.
- Seal and Insulate Ducts: Leaks in ductwork can significantly decrease the airflow, causing your unit to work harder. Sealing leaks and insulating ducts helps prevent cold air from escaping so that it reaches all areas of your home.
- Regular Maintenance: Routine checks and maintenance of your HVAC systems mitigate airflow issues before they worsen. This includes checking filters, coils, and fittings to ensure they are not obstructed or damaged.
- Optimal Duct Sizing: Incorrect duct sizing can significantly restrict airflow. Ensuring your ductwork is appropriately sized for your system is crucial for maintaining efficient airflow.
Implementing these strategies can go a long way in improving your HVAC system’s longevity and overall performance.
Advanced Solutions for Enhanced Airflow
For those looking to optimize their system further, consider the following:
- Install Multi-Speed Fans: These fans adjust speeds based on demand and can greatly enhance air distribution throughout your home.
- Upgrade to a Variable Speed Blower: This type of blower can vary its speed to better control airflow, enhancing air distribution and comfort.
- Consider a Zoning System: This allows you to independently control the temperature in different areas or zones within your house, improving overall comfort and efficiency.
How Can You Get Ahead of Potential Airflow Problems in Lexington, KY?
Airflow might not necessarily be at the forefront of your mind when thinking about indoor comfort — until there’s a problem. However, dealing with improper airflow can lead to serious issues. It’s generally best to find ways to avoid these problems in the first place, which means investing in proper installation and maintenance.
When installing your air conditioning system, take the time to speak with your contractors and ensure they understand your usage needs and your home’s layout. This way, they can provide you with a more effective installation.
After your system is installed, don’t forget to schedule regular maintenance. Generally, it’s best to service your system twice a year: once in the spring and once in the fall. This habit can help you get ahead of any problems and keep the air flowing through your home as it should.

Facing a significant AC repair bill is one of the more stressful moments of homeownership — particularly in the middle of a Lexington, KY summer. The question of whether to repair the existing system or put that money toward a replacement isn't always straightforward, and the wrong decision can cost thousands of dollars in either direction. At Watson Heating & Air, we've helped Lexington homeowners navigate this decision honestly since 2011. Here's how we think through it. Signs Your AC Unit Needs Repair or Replacement The symptoms that prompt this question are usually the same regardless of which answer turns out to be right: the system is struggling to cool the home, energy bills have risen without explanation, or the unit has required service more than once in the past year. Strange noises — grinding, rattling, or high-pitched squealing — can indicate mechanical failures in the compressor or fan components. Warm air from supply vents despite the system running, uneven cooling between rooms, and visible ice on the refrigerant lines are all symptoms worth taking seriously. If your system is over 10 years old and any of these signs are present, a professional evaluation is overdue. Our AC repair service in Lexington includes an honest assessment of whether repair or replacement makes more financial sense for your specific system. Key Factors in the Repair vs. Replace Decision The age of the system is the starting point. Most central AC units have a useful life of 12 to 15 years under typical Lexington conditions. A system in that range that requires a major repair — compressor replacement, condenser coil replacement, or refrigerant system work — is approaching the point where replacement is the more economical long-term choice. Repair frequency matters as much as repair cost. One significant repair on an otherwise reliable 8-year-old system is usually worth doing. A system that has required two or three service calls in a single season is signaling broader deterioration. Energy efficiency is also worth considering: a system more than 10 years old operates at a significantly lower efficiency rating than modern units. The energy cost difference between an aging 10 SEER unit and a modern 18 SEER system can meaningfully offset the cost of replacement over time. Cost Analysis: Weighing Repair Against Replacement A common rule of thumb is the "5,000 rule": multiply the system's age by the repair cost. If that number exceeds $5,000, replacement is generally the better value. It's a rough guide, but it captures the right relationship — the older the system, the less justifiable a major repair becomes. Repair costs: parts, labor, and the likelihood of the same or related components failing again in the near term. Replacement costs: equipment, installation, and any ductwork modifications needed to accommodate a new system. Long-term savings: energy efficiency gains from a modern system and the value of a new manufacturer's warranty. For systems using R-22 refrigerant — which was phased out of production and has become significantly more expensive to source — the calculation shifts further toward replacement, since any refrigerant-related repair carries a steep parts premium. Watson Heating & Air provides upfront pricing for both options so Lexington homeowners can compare the numbers directly. The Benefits of Upgrading to a New AC System Modern AC systems offer meaningful performance improvements over systems installed 10 or more years ago. Higher SEER ratings translate directly to lower monthly operating costs. Two-stage and variable-speed compressors maintain more consistent temperatures and better humidity control compared to the single-stage systems common in older equipment. A new system also comes with a manufacturer's warranty that covers parts for 5 to 10 years, depending on the equipment and whether it's registered after installation. That warranty coverage eliminates a significant source of unexpected repair costs during the period when a new system is most likely to have any issues. Watson Heating & Air backs our installations with professional installation warranties as well. For Lexington homeowners weighing a large repair on aging equipment, the combination of lower operating costs, warranty coverage, and improved comfort makes AC installation in Lexington worth taking seriously. How Watson Heating & Air Helps You Decide We approach this conversation the same way we'd approach it for our own family: honestly, with the long-term cost in mind, not just the immediate transaction. Our technicians evaluate your current system's condition, refrigerant type, age, efficiency rating, and repair history, and give you a clear comparison between what continued repairs will likely cost versus what a replacement would cost and save. Same-day service is available throughout Lexington and Central Kentucky, and our financing options make a replacement more accessible when the numbers favor it. When a repair genuinely makes sense, we'll tell you that too.
Ductless mini splits have become a more common topic of conversation in Richmond, KY over the past several years, and for good reason. Whether you're dealing with an older home that has no existing ductwork, a new addition that doesn't connect to the central system, or a room that never quite reaches the right temperature, mini splits offer a solution that central AC can't always match. At Watson Heating & Air, we've installed mini splits throughout the Richmond area and consistently see them deliver on their promise when they're the right fit for the home. What Are Ductless Mini Splits and How Do They Work? A ductless mini split system consists of an outdoor compressor unit and one or more indoor air-handling units connected by a refrigerant line, power cable, and condensate drain that runs through a small hole in the wall or ceiling. Each indoor unit conditions the space it's installed in independently, operating on its own thermostat and fan speed. The same refrigerant-based technology that cools your home also allows mini splits to heat it, making them a year-round comfort solution. In Richmond's climate — where summers are hot and humid and winters are cold but not extreme — that dual-function capability is a genuine advantage. Watson Heating & Air's ductless mini-split installation and service covers both residential and commercial applications throughout the Richmond area. Key Advantages of Ductless Mini Splits for Richmond Homes The most compelling advantage in a Richmond context is zoning. Each indoor unit operates independently, which means you can cool the living room and bedroom to different temperatures, or avoid conditioning rooms that aren't in use. For a multi-story home in the Battlefield Commons or Glades Crossing areas where upstairs rooms run noticeably warmer than downstairs, a mini split upstairs can address that imbalance without requiring ductwork modifications. Installation is significantly less invasive than adding or extending ductwork. In Richmond's older homes near the EKU campus or downtown areas, where walls aren't set up to accommodate ductwork easily, a mini split can be installed in a day without major renovation. The quiet operation of the indoor units and the absence of duct losses also contribute to a system that runs more efficiently than most central systems in real-world conditions. Our AC installation service in Richmond includes professional load calculations to ensure the right unit sizing before installation. Cost Considerations: Is the Investment Worth It? The upfront cost of a ductless mini split is higher than a standard central AC installation in a home that already has ductwork. That's the honest answer. But the comparison changes significantly in a few common scenarios: For homes without existing ductwork, the cost of installing a duct system for central AC often exceeds the cost of a mini split system. For single-room or zone additions where extending the central system isn't practical, mini splits are almost always the more economical choice. For homeowners focused on long-term operating costs, mini splits' efficiency advantage — particularly their ability to avoid the duct losses that reduce central AC efficiency — can produce meaningful savings over a 10 to 15-year equipment lifespan. Watson Heating & Air offers flexible financing options to make either system more manageable, and our team provides honest side-by-side cost projections so you can make an informed decision. How Do Mini Splits Compare to Traditional HVAC Systems? Central AC systems remain the practical choice for whole-home cooling in homes with well-maintained ductwork. They're familiar, effective, and — in the right context — cost-efficient. Mini splits don't replace central systems in every situation, but they outperform them in specific ones. The key differences: mini splits avoid duct losses entirely (which account for 20-30% of energy waste in typical central systems), allow independent zone control, and can be installed without structural modifications. They require more frequent filter cleaning on the indoor unit heads, but overall maintenance demands are similar to central systems. For Richmond homeowners evaluating both options, the decision usually comes down to whether existing ductwork is in good enough condition to be worth using. What to Look for When Choosing a Mini Split System The most important factor is proper sizing. An undersized unit will run continuously without reaching the target temperature; an oversized unit will short-cycle, leaving the room humid and uncomfortable. Proper sizing requires a Manual J load calculation that accounts for the room's square footage, ceiling height, window area and orientation, and insulation levels. SEER rating (efficiency) and sound levels are also worth comparing across models. Watson Heating & Air recommends systems from manufacturers whose parts and support networks are reliable long-term, and our licensed technicians install every system to manufacturer specifications so warranties remain valid.
Uneven cooling is one of the most frustrating comfort issues a homeowner can deal with — and one of the most common calls we receive from Kirksville, KY residents during the summer months. When one end of the house is comfortable and the other is sweltering, or when upstairs rooms stay warm no matter how low the thermostat is set, the cause is rarely mysterious. In our experience working throughout Kirksville and the surrounding areas, the same six factors come up again and again. 1. Poor Insulation Insulation is the thermal barrier between your conditioned indoor air and the heat outside. In older Kirksville homes, insulation in walls, attics, and crawl spaces often falls well short of modern standards. Heat transfers through those gaps faster than the HVAC system can compensate, creating hot spots in rooms with inadequate insulation — particularly south-facing rooms and upper floors where heat accumulates. A professional energy assessment can identify where insulation is failing in your home. Upgrading insulation in key areas doesn't just improve comfort — it reduces the load on your HVAC system and typically lowers energy bills noticeably. In combination with a properly sized and maintained AC system in Kirksville , good insulation is what makes consistent room-to-room temperatures achievable. 2. An Inefficient or Undersized HVAC System Reduced Airflow An HVAC system that's undersized for the square footage it's trying to condition will always struggle during peak demand. In a Kirksville summer, that means the system runs continuously without ever fully reaching the thermostat setpoint — and some rooms get less airflow than others simply because the system doesn't have enough capacity to serve them all. Reduced airflow from specific vents is often the first physical symptom homeowners notice. Increased Energy Bills An inefficient system doesn't just fail to cool evenly — it does so while running up energy costs. If your bills have climbed without a change in usage, and rooms still aren't comfortable, the system may be working at maximum output just to maintain inadequate results. This is a strong signal that a professional assessment is overdue. Frequent System Breakdowns A system that's constantly being pushed beyond its capacity breaks down more often. Short cycling, tripped breakers, and compressor failures are all more common in systems that are either too small for the home or have deteriorated past the point of reliable operation. If you're calling for repairs repeatedly through a single cooling season, the underlying issue may be capacity rather than a single component. 3. Blocked Air Vents Common Blockage Sources Blocked vents are one of the simplest causes of uneven cooling — and one of the most overlooked. Furniture pushed against a supply vent, long drapes hanging over a register, or a buildup of dust and debris in the vent itself can all disrupt the airflow balance that the system was designed to maintain. In Kirksville homes with older carpet and higher dust levels, vent buildup accelerates. Impact on Room Comfort When a supply vent is blocked, the room it's supposed to serve gets less conditioned air — while the rest of the system continues operating as if that room were being served normally. The result is a single room that stays warm while adjacent rooms cool down. Checking every supply vent in the home and ensuring none are obstructed is a fast, no-cost first step when dealing with uneven cooling. Proper ductwork and airflow balance supports even distribution throughout the home. 4. Thermostat Problems Thermostats read the temperature at their specific location — which may not reflect the temperature of the rest of the house. A thermostat placed near a west-facing window, close to a stove or oven, or in a poorly ventilated hallway will read inaccurately, causing the system to cycle off before other rooms have reached a comfortable temperature. Calibration drift in older analog thermostats can also cause the system to shut off short of the actual target temperature. If your thermostat is more than 10 years old or placed in a poor location, replacing it with a properly positioned programmable or smart thermostat can resolve uneven cooling that seems unexplainable by other means. 5. Ductwork Leaks and Restrictions Leaking ductwork is one of the most significant and underdiagnosed causes of uneven cooling. When conditioned air escapes into wall cavities, attic spaces, or crawl spaces before reaching its intended vent, the rooms that duct serves receive less airflow — sometimes dramatically less. Duct leaks at joints and transitions are common in homes where ductwork hasn't been professionally inspected in several years. Kinked flex duct, crushed sections, or improperly sized duct runs are equally damaging. Professionally sealing and repairing ductwork restores the airflow balance the system was designed to deliver and often has a measurable impact on both comfort and energy efficiency. 6. Uneven Sunlight Exposure The orientation and layout of your Kirksville home affects how much solar heat each room absorbs throughout the day. South- and west-facing rooms receive the most direct sun exposure during the hottest hours and can be significantly warmer than north-facing rooms, regardless of how well the HVAC system is performing. This is particularly pronounced in homes with large windows or minimal window shading. Addressing solar gain through window treatments, exterior shading, or attic insulation reduces the heat load in problem rooms and makes the HVAC system's job easier. In extreme cases, a zoning system that allows different parts of the home to be conditioned at different setpoints may be the most effective long-term solution.
It seems like a simple question — what size air filter does my HVAC system take? — but it's one we hear regularly from Nicholasville, KY homeowners who've found themselves at the hardware store staring at a wall of options. Getting the wrong size is more consequential than it might seem: a filter that's too small creates gaps that allow unfiltered air to bypass it entirely, while a filter that's too large won't seat properly in the filter cabinet. Here's how to get the right answer quickly, and what to consider when you're selecting a replacement. How to Determine the Right Air Filter Size The most reliable source for filter dimensions is the existing filter in your system. Most filters have their dimensions printed on the cardboard frame: length x width x thickness. Standard residential filters are most commonly listed as nominal dimensions, which are slightly larger than the actual physical size, so always use the dimensions printed on the current filter rather than measuring the slot directly. If you can't find a filter to reference, the filter slot dimensions printed in your system's owner's manual are the next best source. Your HVAC cabinet may also have the filter size printed inside the access door. For homeowners with older systems or those who aren't sure whether the current filter is even the right size, Watson Heating & Air's AC maintenance service in Nicholasville can confirm the correct filter specification during a service visit. Common Air Filter Sizes in Nicholasville, KY In the Nicholasville area, we see a range of standard filter sizes depending on the age and manufacturer of the installed system. The most common 1-inch filter dimensions are: 16x20x1 — very common in standard residential air handlers 20x20x1 — found in many mid-range systems 20x25x1 — common in larger or higher-capacity systems 16x25x1 and 14x20x1 — more frequently seen in older homes throughout Jessamine County Thickness matters too. Many Nicholasville homes have systems designed for 1-inch filters, but there's a meaningful efficiency and longevity advantage to upgrading to a 4- or 5-inch media filter if your cabinet supports it. Thicker media filters last longer between changes and provide better particle capture. Consistent air filter replacement on the right schedule keeps the system performing as designed. Factors That Affect Your Filter Size Selection Beyond the physical dimensions, several factors shape the best filter choice for your specific Nicholasville home: HVAC system capacity: Larger systems with higher airflow ratings can handle filters with higher MERV ratings without airflow restriction; smaller or older systems may perform better with a mid-range MERV filter. Household conditions: Homes with pets, high dust levels, or allergy sufferers benefit from higher-MERV filters that capture smaller particles. Local environment: Nicholasville's proximity to agricultural areas means seasonal pollen and dust levels can run higher than in more urban settings, which affects how quickly filters load up. Filter access frequency: If the filter location is difficult to reach, a longer-lasting 4- or 5-inch media filter reduces how often you need to access it. Signs You Might Need a Different Filter Size or Type If you're changing your filter on schedule and still noticing issues, the filter itself may not be the right fit. Reduced airflow despite a clean filter can indicate that a higher-MERV filter is restricting airflow beyond what the system is designed to handle. Persistent dust on surfaces after filter changes can mean the filter dimensions aren't providing a proper seal and unfiltered air is bypassing it. Worsening allergy symptoms despite regular filter changes may indicate that the current filter type isn't capturing fine particles effectively. Any of these patterns is worth discussing with a professional who can evaluate both the filter specification and the overall system condition. How to Replace and Maintain Your Air Filter Properly Filter replacement should always start with the system powered off. Remove the old filter, note the airflow direction arrow printed on the frame, and install the new filter with that arrow pointing toward the blower — not toward the return air side. Installing a filter backward significantly reduces its effectiveness. For 1-inch filters in most Nicholasville homes, check the filter monthly and replace it when it appears gray and dense — don't wait for the scheduled date if it loads up early. For deeper media filters, quarterly checks and replacement every 6 to 12 months is typical, depending on household conditions.

Air filter replacement is one of the simplest and most impactful things an Irvine, KY homeowner can do for their HVAC system — yet it's one of the tasks that most commonly gets pushed aside. In a community like Irvine, where homes range from older farmhouses to newer construction along the Estill County corridor, filter requirements can vary considerably. The right replacement schedule depends on your household, your system, and the conditions inside and around your home. Why Regular Air Filter Changes Matter for Your HVAC System Your air filter's job is to keep dust, debris, and airborne particles from being pulled into the HVAC system, where they can coat the evaporator coil, clog the blower motor, and restrict airflow through the ductwork. When a filter becomes clogged, it doesn't just reduce air quality — it forces the system to work harder to move air through the resistance, which increases energy consumption and accelerates wear on components. The consequences of neglecting filter changes show up gradually: higher energy bills, rooms that don't heat or cool evenly, and eventually equipment failures that could have been avoided. Watson Heating & Air's AC maintenance service in Irvine includes a filter check on every visit, but the schedule between professional visits is the homeowner's responsibility. How Often Should You Change Your Air Filter in Irvine, KY? For most Irvine homes, every one to three months is the appropriate target. That's a wide range, and where you fall within it depends on several factors: Homes with pets should change filters monthly, as dander and hair clog filters significantly faster than dust alone. Households with allergy sufferers benefit from a tighter schedule — monthly or every six weeks — and from using a higher-MERV filter that captures smaller particles. Homes with minimal occupancy or no pets can often stretch to every 90 days. During peak HVAC use months — typically June through August and December through February in Irvine — check filters more frequently, as higher run time means faster buildup. The bottom line: check the filter monthly and replace it when it looks gray and dense. Don't rely purely on calendar dates. Signs Your Air Filter Needs Immediate Replacement There are a few clear signals that the filter is past due and affecting system performance: Energy bills that have risen without a corresponding change in usage or weather — a clogged filter forces the system to work harder. Increased dust on surfaces throughout the home, particularly near vents — this indicates the filter is no longer trapping particles effectively. Reduced airflow from supply vents — hold your hand near a vent when the system is running; noticeably weak airflow often points to a restricted filter. Short cycling — the system turning on and off frequently — which can indicate the blower is struggling against restricted airflow. If your air filter replacement schedule has slipped, these symptoms are a prompt to act now rather than wait for the next scheduled change. The Benefits of Using High-Quality Air Filters Not all filters perform equally. Standard fiberglass filters are inexpensive but capture only large particles. Pleated filters with a higher MERV rating (between 8 and 13 is the practical sweet spot for residential systems) capture smaller particles including pollen, mold spores, and fine dust without restricting airflow to the point of system strain. For Irvine homes where outdoor pollen and agricultural dust are seasonal concerns, a higher-quality pleated filter is typically worth the additional cost. It protects the HVAC equipment, improves air quality, and often lasts the full replacement interval without needing to be checked mid-cycle. Tips for Choosing the Right Air Filter When selecting a replacement filter: Match the exact dimensions of the current filter — even a slightly undersized filter creates gaps that allow unfiltered air to bypass it. Choose a MERV rating between 8 and 13 for most residential systems; higher ratings restrict airflow more and may not be appropriate for older or less powerful systems. Consider a 4- or 5-inch deep media filter if your system's filter cabinet accommodates it — these last significantly longer than 1-inch filters and provide better filtration. If allergies are a concern, look for filters specifically rated for allergen capture rather than just dust.
Indoor air quality often gets overlooked compared to other home comfort concerns — but what your family breathes matters just as much as how cool or warm the house is. UV air purifiers have become an increasingly popular addition to HVAC systems in Richmond, KY homes, and the science behind them is straightforward: ultraviolet light disrupts the DNA of airborne microorganisms, rendering them unable to reproduce. The result is cleaner air circulating through your home with every cycle. At Watson Heating & Air, we install and service UV air purifiers throughout the Richmond area, and here's what homeowners consistently report after installation. 1. Elimination of Harmful Bacteria and Viruses UV air purifiers target the pathogens that standard HVAC filters don't catch. As air passes through the system and across the UV lamp, bacteria and viruses are exposed to concentrated ultraviolet light that breaks down their cellular structure. This is particularly valuable during flu season or when a household member is sick, as it reduces the circulation of active pathogens through the air supply. For Richmond homeowners who want a more complete approach to home health, pairing a UV purifier with a properly maintained HVAC system provides an added layer of protection that goes beyond filtration. Our UV air purifier installation service integrates the unit directly into your existing system for whole-home coverage. 2. Reduction of Allergens UV light is effective against mold spores, which are a major allergen source in homes throughout Central Kentucky. Richmond's humid summers create conditions where mold spores thrive — in ductwork, on coil surfaces, and in drain pans where moisture accumulates. A UV purifier installed near the evaporator coil addresses this directly, inhibiting mold growth at one of the most vulnerable points in the system. Dust mites, pet dander, and outdoor pollen that makes its way inside are also reduced. For households with allergy sufferers or young children, the cumulative effect is fewer triggers in the air and noticeably easier breathing through high-pollen months. 3. Control of Household Odors Eliminate Odor-Causing Bacteria Many household odors — musty basement air, pet smells, cooking odors that linger — are caused by airborne bacteria and organic particles. UV light breaks down the bacteria at their source rather than simply masking the smell. Homeowners consistently report fresher-smelling air within days of installation, particularly in homes where pets or moisture have been an issue. Neutralize Volatile Organic Compounds Volatile organic compounds (VOCs) off-gas from paints, cleaning products, new furniture, and building materials. In a well-sealed home, these compounds accumulate in the air supply over time. Advanced UV purifiers equipped with photocatalytic oxidation technology can break down VOCs, removing the chemical source of odors rather than filtering around them. Improve Overall Air Freshness The cumulative effect of removing bacteria, mold spores, and VOCs is air that simply smells cleaner. Many Richmond homeowners describe this as the most immediately noticeable change after installation — a reduction in the subtle background staleness that builds up in any home with consistent occupancy and limited fresh-air exchange. 4. Reduced Risk of Respiratory Issues For families dealing with asthma, chronic allergies, or other respiratory sensitivities, the air quality inside the home can have a direct impact on day-to-day health. By reducing the concentration of mold spores, bacteria, and allergens in the air, UV purifiers can decrease the frequency and severity of respiratory symptoms. This benefit is especially relevant in Richmond, where seasonal pollen counts and humidity levels create challenging conditions for sensitive individuals. A UV purifier doesn't replace medical treatment, but it does reduce the environmental load your family's respiratory systems have to handle every day. 5. HVAC System Protection UV purifiers installed near the evaporator coil do more than improve air quality — they protect the coil itself from mold and bacterial growth. A clean coil operates more efficiently, transfers heat more effectively, and requires less frequent cleaning. Over time, this contributes to lower energy bills and extends the working life of the coil. This is one reason we recommend UV purifiers as part of a broader indoor air quality solution rather than a standalone add-on. The system benefits are real and measurable. 6. How to Choose the Right UV Air Purifier Selecting the right unit depends on your home's square footage, the placement within your HVAC system, and whether you're primarily targeting microbial growth, VOC reduction, or both. Single-lamp units installed at the coil are effective for mold control; dual-lamp systems that treat both the coil and the air stream offer more comprehensive coverage. Watson Heating & Air helps Richmond homeowners evaluate their specific needs and recommends units that fit their system and goals. Every installation is carried out by licensed technicians who ensure proper placement and secure integration with the existing HVAC setup. 7. Ongoing Maintenance for Lasting Performance UV lamps lose effectiveness over time and should be replaced approximately every 12 months, depending on the model. During annual HVAC maintenance visits, we inspect the purifier, verify lamp output, and replace the bulb as needed. The pre-filter, if the unit has one, should be checked on the same schedule as your HVAC filter. Watson Heating & Air's Preferred Member Club includes routine UV purifier checks as part of our preventive maintenance visits, so Richmond homeowners don't have to track the lamp replacement schedule on their own.
