Change Your Air Filter in Charlotte and Rock Hill

If you have a central heating and air-conditioning system, the same filter or filters work for the heating and the cooling. The filter(s) clean out all the debris, dust, and allergens from the air circulating throughout your house. Depending upon which type of filter you are using, depends on how often your filters should be replaced.


As a general rule, pleated air filters should be replaced every 90 days. Low-cost, throw-away fiberglass filters should be changed out every 30 days. Clogged filters can lead to expensive breakdowns. Changing the air filters is an easy way to increase the efficiency of your equipment.

Keep the area around the condenser clean

The outside unit, whether it is a heat pump, condensing unit, or a package unit engages when in cooling mode for the summer. It is important to keep the surrounding area free from debris, lawn clippings, or trash.



Such items can restrict air from circulating into your system, which can damage your equipment. Also, lawn clippings, weeds, and leaves contain organic matter which hold bacteria. If left around your unit, the bacteria can infiltrate the air circulating throughout your home. Keep at least one foot clearance surrounding your outdoor unit to avoid any issues. If you see branches, sticks, or debris inside the unit call a professional service contractor to remove it.

How to Assess Your Air Conditioning System in Rock Hill, SC

  • Turn on the system in AC mode and allow it to run for 15 minutes.
  • Put a thermometer in the supply register vent, which is pushing cool air into the room. Choose a vent close to the unit.
  • Hold the thermometer there for 4-5 minutes, note the temperature.
  • Find the nearest return vent, which is drawing air from the room, leave the thermometer there for another 4-5 minutes, note the temperature.


The temperature from the supply vent should be 14 to 20 degrees cooler than the return vent. If it is not, you should schedule a service appointment with your local HVAC contractor.  Carolina Refrigeration Heating & Cooling is here to help and answer any questions you may have about your air conditioning system.
