The long, humid summers in Greenwood, SC, make you depend on your air conditioning system for relief. Waking up or coming home to vents blowing warm air on a hot summer’s day is an unpleasant surprise. Here are some of the reasons why your air conditioning system is blowing hot air and some tips on when to call for an AC repair or maintenance visit.

Refrigerant Leak

Air conditioners use a chemical refrigerant. The refrigerant absorbs heat from your home’s air and transfers it to the outdoors. A refrigerant leak means that less of the hot air can be absorbed. If too much refrigerant leaks, the system’s pressure safety valve is triggered, and the system shuts down. This could leave you with vents blowing warm air. Refrigerant leaks require professional AC repairs.

Dirty Air Filter or Condensate Line

A dirty air filter impedes the flow of cool air from the air handler to your vents. An obstructed condensate line could shut down your entire cooling system. Regular AC maintenance includes checking and replacing dirty air filters. It also includes cleaning the condensate line. Other aspects of a AC maintenance include checking the refrigerant level, cleaning the coils and inspecting the thermostat. A spring tune-up of your air conditioner prevents these problems and saves you money by avoiding unnecessary AC repair costs.

Capacitor Problem

A capacitor problem could prevent your air conditioning system from turning on. According to the Department of Energy, electrical problems like these can often be detected during an AC maintenance visit. The capacitor can wear out if your air conditioning system turns on and off a lot or can be caused by power surges. This also happens with over-sized air conditioning systems. Over time, corrosion can wear out the system’s wires and sensors. A capacitor problem requires a professional AC repair.
