Air ConditioningTips and AdviceMy Air-Conditioner is Running, But Not Cooling, What Should I Do in Charlotte?

July 30, 2021by Dev

As a homeowner, one of the most frustrating issues is a problem with your air-conditioner during the summer heat. There are a few things you can do to troubleshoot your heating and air conditioning system if you discover your A/C unit is operating but not cooling properly. Of course, it is always wise to contact an HVAC professional for service and repairs. Identifying the possible root of the problem and telling the technician may help to resolve your issue quicker.

Check Your Thermostat

If you notice a problem with your heating or air conditioning, check your thermostat. Verify it is set to the proper temperature mode, cooling or heating. Make sure the thermostat is not working in just “fan mode.” This keeps the air-handler fan on at all times, regardless of any preset temperature. Also, if your thermostat uses batteries, check them, they could be dead?

Check Your Air Filter

Just as with your car, the air filter in your home HVAC system is crucial to the efficiency and performance of the equipment. A clogged filter will lead to increased operating costs and a possibility of a premature failure of the system. According to, you should replace the filter every one to three months depending on the type you have. Always replace it with a good quality filter. The cheapest is not always the best.

Check Your Condensate Drain

Air conditioners remove moisture from the air and the water is typically drained through a hose or pipe which can become clogged with algae or debris. If the drain becomes clogged, the unit should shut down…sometimes causing the thermostat to go blank. This is a very important safety feature that prevents water from backing up into the drain pan, which could overflow and cause damage to the home. The pipe can be replaced; if necessary, but typically is cleaned with a mild bleach solution.

Ice On Your Outdoor Unit

If your equipment is operating, but not producing cool air, check the outdoor section and verify no ice is visible. If you see ice, turn the system off immediately and contact your trusted local HVAC service contractor. Most contractors will ask if the unit has ice. The unit must be thawed in order for the technician to diagnose a problem and will ask you to turn the system off. A frozen coil can be the result of any number of issues, filters clogged, restricted air flow, defective mechanical parts, or refrigerant issues. Your licensed contractor will need to investigate and determine the issue.

Call A Professional HVAC Company in Charlotte

If you have checked the aforementioned issues and continue to have problems with your air-conditioner keeping your home cool, call a licensed contractor. A trained, professional technician will ensure your system will operate at peak performance. They will inspect your heating and cooling system, so it remains compliant with any local and national building codes. When in doubt, call a local, licensed contractor rather than risk damaging your system further by attempting a repair yourself.
