Why is my air conditioning running constantly? That’s a common question in the hot summer months. If yours just keeps running and running, some of these issues could be the cause. Take a look:
Dirty Air Filter
Your air filter is the gateway to your HVAC unit. If it gets dirty or clogged, it can mess up the whole system. The dirt and debris keep the air from flowing properly into the unit, and the air conditioner has to work overtime to keep up with demand. When this happens, the coils don’t get enough circulation to remove humidity and cool the air. This causes the system to run to try to bring the indoor temperature down.
Low Refrigerant/ at the end of low refrigerant
Refrigerant is what helps your AC unit cool down the air that circulates through the system and into your home. When the refrigerant level drops, your AC can’t keep up. As a result, it will run and run to try to meet the temperature set on your thermostat.
Faulty or Mis-Set Thermostat
It’s easy to assume your thermostat is set properly, and just as easy for it to get bumped or changed. If your thermostat gets changed from “auto” to “fan,” it will run constantly, even if it’s not blowing cool air.
Dirty Evaporator Coils
If the evaporator coils on your outdoor unit get dirty, it can block airflow. When air can’t pass over the surface of the coils, it doesn’t get cool. If the air isn’t cool, the system will keep running to try to meet the demands of the thermostat.
No matter the cause, if your house is heating up, but the AC is running constantly, it’s time for a call to H.H. Hovey Heating and Cooling. One of our expert technicians can quickly have your air conditioner back in working order.
