Why Does My Air Conditioner Fail to Turn Off?

Is your air conditioner driving you insane because it refuses to turn off? The constant whirring of it never stopping can be an annoyance? Not to mention the financial implications when your electric bill arrives at the end of the month. Various issues can cause this, and it may be easier to resolve than you think. When all else fails, trained professionals are available to fix things for the air conditioner in Mesquite, TX quickly.

  • Wrong Setting of Fan

Checking the fan settings is the simplest place to start troubleshooting an AC constantly running. Most of the time, you’ll want the fan set to Auto. The fan only operates when your unit is heating or cooling. The fan circulates the conditioned air throughout your home, bringing the temperature to the desired levels. If the fan is turned on, it will run continuously regardless of whether the AC is in a cooling cycle. If this is the case, you’re in luck because your air conditioner isn’t broken.

  • Size of the Air Conditioner

The air conditioner works by absorbing warm air from your home, separating moisture from humidity, and cooling it before redistributing it through the air vents. It will continue until the temperature reaches the temperature you set on the thermostat. The AC will then turn off. This is known as an AC cycle, and it typically lasts 20 to 30 minutes. When the indoor temperature rises, the AC will begin another cycle. If you install an AC replacement in Mesquite, TXthat is too small for your home. It will work in overdrive in futile attempts to reach the desired temperature. Because it never turns off, its energy consumption will be reflected in your utility bills.

  • Low Refrigeration

 If refrigerant leaks from damaged coils, cracked refrigerant lines, or a faulty expansion valve, the air conditioner cannot absorb enough heat from the hot air in the home. The air conditioner will continue to run to reduce the indoor temperature.

  • Condenser Coils 

The heat from the refrigerant that cycles through the coil after the compressor adds pressure is released by the condenser coils in the outdoor unit. The surface area is required to release heat, frequently hampered by dirt, dust, and grime that accumulates on the condenser coil. When the coil does not have enough area to release heat effectively, the system cannot sufficiently cool the indoor air and will continue to operate as it attempts to lower the temperature.

  • Dirty Air Filter

When an air filter becomes completely clogged with pollutants, it becomes restrictive, preventing air from freely flowing through the air conditioner. Without adequate airflow, the cooling system cannot cool air to the proper temperature and must run for longer periods to keep up with cooling demands inside the home.
