Is the summer weather making you sweat? If you are wondering how to help your AC keep up, the tips below will help your system beat the heat. As the trusted AC repair experts in Richmond, KY, our family-owned team can solve any air conditioner problem.
1. Block the Sun
The sun is the biggest source of heat in your home. When it shines through your windows, it raises indoor temperatures significantly. Installing window treatments like solar shades or light-blocking drapes cuts the heat your home gains. With a steadier temperature, your AC runs less and does not have to work as hard.
2. Seal Leaks
Tiny leaks in your doors, windows, and insulation let cold air out and warm air in. This increases the effort your AC puts in while delivering worse results. Improve your insulation and seal those leaks to give your system a break.
3. Maintain Your Filter
Your AC's air filter delivers clean, cool air by removing dust and allergens. Most filters need changing or cleaning every 30 to 90 days, or more often if you smoke, have pets, or live in a polluted area. A clogged filter reduces airflow and forces your AC to work harder to keep up, so keeping it clean is the easiest way to boost cooling power.
4. Increase Airflow
If you want to help your AC keep up with the heat, improve its airflow. The evaporator and condenser coils easily collect dirt, which cuts airflow and cooling output. Keep your air conditioner clean inside and out so it can hold a comfortable temperature more easily. Professional AC coil cleaning restores airflow a household duster cannot reach.
5. Inspect Ductwork
Your home relies on a network of ducts and vents to move and distribute cool air. Ducts can disconnect, tear, or leak, which keeps cold air from reaching your rooms. If some rooms cool slower than others or your AC struggles to keep up, have professionals inspect your ductwork. Watson Heating & Air handles ductwork repair across Lexington to get even cooling back.
6. Utilize Fans
Ceiling fans are a great way to help your AC keep up with the heat. A fan can lower a room's perceived temperature by several degrees, so your AC works less and you can set the thermostat higher while staying comfortable. For best results, run fans counterclockwise in summer to push cool air down.
7. Turn Up the Thermostat
Set your thermostat to the most efficient temperature. When you use other cooling methods together, 78 degrees Fahrenheit keeps your AC working well while maintaining comfort. It feels counterintuitive, but never crank the temperature down when the AC is not keeping up. If it cannot hold 71 degrees, dropping it to 68 only makes it work harder for the same result.
8. Clean Outside
The outdoor unit holds the condenser coil, which is essential for efficient cooling. Because it sits outside, it quickly gathers dirt or gets crowded by plant growth. Clean your outdoor unit regularly and keep a two-foot perimeter clear of plants and features.
9. Spend Time Outside
You can help your AC keep up by getting out of the house during peak heat. Do heat-producing activities like cooking or exercising outdoors to avoid warming your interior. You can also visit a park or an air-conditioned business, staying cool while giving your AC a break, since you should not run it hard when no one is home.

Frequently Asked Questions
How can I help my AC keep up on the hottest days?
Reduce the heat your home takes in and the work your AC has to do. Block direct sun with shades, seal leaks around doors and windows, keep the filter clean, and run ceiling fans so you can set the thermostat a little higher. These steps together make a real difference on peak days.
What temperature should I set my thermostat in summer?
Set it to 78 degrees Fahrenheit for the best balance of comfort and efficiency, especially when paired with fans and shaded windows. Setting it far lower forces the system to overwork without cooling any faster.
Why is my AC running constantly but not cooling?
This usually points to restricted airflow or dirty coils, a clogged filter, or leaking ductwork. Cleaning the filter and clearing the outdoor unit often helps. If it continues, have a professional inspect the coils and ducts.

When should I call a professional instead of troubleshooting myself?
Call a professional if a clean filter and clear coils do not restore cooling, or if you notice weak airflow, warm air, or uneven room temperatures. Watson Heating & Air can pinpoint the issue fast. Schedule your appointment today to stay comfortable all summer.
