Common Reasons Why Your Air Conditioner Runs All The Time And Won't Shut Off
If your air conditioner has been running constantly, and you're not sure when it shut down the last time, it may be time to call for repairs. An AC that never shuts down will drive up your power bill and stress your system. Whether it's blowing cool air or not, an AC that doesn't cycle off is a sign of a problem that needs to be fixed. Here are some possible causes and solutions for an air conditioner that doesn't cycle off.
The Refrigerant Is Low
If the air coming out of the register isn't chilled, the AC may be running all the time because it can't reach the temperature set on the thermostat. This can happen when there is a refrigerant leak or when the coils are coated with dust and need to be cleaned. If the air is cold, then there might be a problem with the thermostat. Either way, you'll need the help of a repair technician to get your AC working again. This might require repairing a tiny leak and filling the refrigerant.
The Condenser Has Worn Parts
Sometimes, the indoor part of the air conditioner will shut down, but the outdoor part keeps running. This might happen when the thermostat has issues, but it can also happen when parts in the condenser are corroded or the unit is dirty. An outside unit that runs all the time is a problem since this can lead to ice buildup on the HVAC and an eventual breakdown. The service technician may need to take the condenser apart and clean it while looking for worn parts that need to be replaced.
The Thermostat Is Malfunctioning
Thermostats can malfunction because of worn parts or loose wires. It's also possible a thermostat will act up if the batteries are low or if the settings are wrong. Be sure to check the thermostat and verify it is on the correct settings and that nothing is interfering with its ability to read the temperature of the room.
It's not a good idea to run your AC continuously when it won't shut down. When you call for an air conditioning service call, ask if you should shut down your AC at the electrical panel or switch so it stops running. Try replacing the filter to see if that helps and check the thermostat. If neither of those actions works, you may need to call in a repair professional to clean and service your AC to get it working properly again and stop wasting your money by using so much power.
