What to Check When Your AC Stops Cooling in Lexington, KY

When your AC unit suddenly stops cooling during a sweltering summer day in Lexington, KY, it can be quite frustrating. You often wonder what could be wrong and where to start. Before you call for professional help, there are several key things you can check for yourself. From adjusting the thermostat to inspecting the air filter, these simple steps might just save you time and money. Let's explore what you should look into first.

Check the Thermostat Settings
Have you checked the thermostat settings yet? It's often the first step you ought to take when your AC stops cooling.
Sometimes, it's as simple as adjusting the temperature or confirming it's set to "cool" rather than "heat." You realize how easy it's to accidentally bump the settings while cleaning or rearranging furniture.
Let's also make certain the thermostat is functioning correctly. If it's unresponsive or displaying unusual readings, it could signal a deeper problem.
You can test this by setting the temperature a few degrees lower and watching for any changes.
If everything seems in order but the AC still isn't cooling, it might be time to call in the experts. Regular maintenance can prevent future ac repair and increase system efficiency by up to 30%.
At Watson Heating & Air, you're here to help you troubleshoot any issues and guarantee your home stays comfortable.
Inspect the Air Filter
One critical aspect to check when your AC stops cooling is the air filter. A dirty or clogged air filter can restrict airflow, making it tough for your unit to cool efficiently.
Let's take a moment to inspect it. Here are three key points to evaluate:
- Check for Dirt and Dust: If the filter looks grimy or discolored, it's time for a replacement. A clean filter promotes better airflow and efficiency.
- Examine the Replacement Frequency: You should aim to replace or clean your filters every 1-3 months, especially during peak usage seasons.
- Select the Right Filter Type: Not all filters are created equal. You can choose a filter that matches your system's needs and your indoor air quality goals. Additionally, regular replacement of the air filter is essential for maintaining indoor air quality, which helps prevent health issues for all household members.
Examine the Outdoor Unit
When your AC stops cooling, it's important to examine the outdoor unit as it plays a crucial role in the system's overall performance.
First, let's verify there's no debris, like leaves or dirt, blocking the condenser. A clear space around the unit helps it operate efficiently.
Next, you should check the fins for any damage; bent fins can hinder airflow and cooling. If you notice any damage, you can gently straighten them using a fin comb or similar tool.
Also, let's look for signs of leaks or pooling water around the unit, as this might indicate a refrigerant issue.
If everything looks good on the surface, you can verify the unit is powered on and listen for any unusual noises. In case of common AC problems, seeking professional assistance can help prevent further damage and ensure optimal performance.
If you still have concerns, it might be time to call our professionals, at Watson Heating & Air, for a thorough inspection and quick resolution.
Review the Ductwork
Inspecting the ductwork is vital when your AC stops cooling, as it directly impacts airflow and temperature regulation throughout your home.
You should check for any visible issues that could disrupt the system's efficiency. Here are three key items to look for:
- Leaks and Gaps: Air can escape from holes or disconnected sections, making your AC work harder than it should.
- Dirt and Debris: Dust buildup can block airflow, so you need to guarantee the ducts are clean and clear.
- Insulation: Proper insulation is essential for maintaining temperature. If it's worn or missing, conditioned air can escape, causing inefficiency. Regular maintenance can help identify and mitigate these issues, ensuring efficient HVAC performance.
Ensure Power Supply Is Stable
A stable power supply is essential for your AC system to function properly. When your air conditioning stops cooling, the first thing you should check is whether the power supply is stable.
You can start by ensuring that the thermostat is set to cooling mode and the temperature is lower than the current room temperature. Next, let's inspect the circuit breaker; it may have tripped, requiring a simple reset.
If you find that the breaker is fine but the AC still isn't working, it's a good idea to check for any blown fuses. Additionally, you should confirm that the outdoor unit is receiving power.
If everything seems in order and the AC still isn't cooling, you might need to call in professionals like Watson Heating & Air. They're committed to restoring your comfort quickly and effectively.

Let's keep your ductwork tight and your power steady, so you can enjoy a revitalizing escape from the summer sun. With a little effort, you can turn your home back into a cool sanctuary.
