Professional HVAC Contractors in Rock Hill, SC

Check your air filters monthly. If there is any discoloration or visible layers of dust, you should change your air filter. Air filters need to be changed every 30 days on average and sometimes every two weeks during summer months when your air conditioning is more frequently used.

Air conditioners that suddenly start making new noises or produce new smells should be checked right away. Other signs that your unit is having problems include its running constantly despite temperatures under 100 degrees Fahrenheit, blowing warm air into the room, or utility bills that increase dramatically despite normal usage.

Indoor air handlers do double duty, removing heat and moisture from the air. They are designed with a small pan to catch the moisture, but occasionally the drain line from the pan may become plugged. If you see water around your indoor air handler, remove the drain line and give it a good cleaning by running vinegar water through it to help clear out any build-up.
