When you combine relative humidity above 60% with days above 90°F, it can make it difficult to scrape through the day, even with the best and most reliable air conditioning system.

AC Short-Cycling—What Might Cause It

Monday, June 15th, 2020

service-tools-air-conditionersYou may not have heard of ­short-cycling, but you may have noticed it in your house. It’s when your air conditioning system turns on and off more often than normal. Your air conditioner’s cooling cycle is the process of it turning on at a request from the thermostat, running until it registers the house has reached the thermostat setting, then shutting down until the thermostat makes a request again. Most AC cycles last for 15 minutes or more, and if you keep the thermostat at the same setting during the day, the cycles should have a steady pattern.

When that pattern becomes the AC turning on and off multiple times over an hour—less than 15 minutes on at a time—then it’s short-cycling.

desk-fanYour air conditioning system has two fans that are essential for it to work. The fan you’re most used to hearing and feeling is the indoor blower fan. This fan is located at the bottom of the HVAC cabinet, where it pulls air from the return air ducts and then pushes it past the evaporator coil, where it’s cooled, and then into the ventilation system.

The second fan is in the condenser cabinet outside. This fan draws air through the grill of the cabinet to run it across the condenser coil and release heat. The fan then pushes this heat through the top of the cabinet.

If either fan stops working, you won’t have a cool home. A broken indoor fan means air won’t move through the ducts. A broken outdoor fan means the AC can’t effectively release the heat it drew from indoors and won’t cool down the home’s air.

What causes these fans to break, and what can you do about it?
