Clogged Drain Pipe

Your air conditioning unit will not turn on if you have a clogged drain pipe.

Wiring Issues

If you have wiring issues that have impacted your air conditioner, you should check if other appliances are also affected. If you hear humming sounds or have seen flickering lights from your appliances, you need someone to check the home wiring to find out the source of the problem.

Problems With Your AC’s Essential Components

Evaporator coils: Your evaporator coil needs regular maintenance like your air filter. When dust and debris build up, your evaporator coil will freeze because it cannot function properly. The dust deters the evaporator coil from absorbing warm air, keeping the heat in. If your air conditioner stops working, a dirty evaporator coil might be the problem.

Thermostat: Another issue that your air conditioning unit might be facing can be due to thermostat issues. Your thermostat is an essential component of your unit. It is considered as the control panel of your system. When it encounters problems, it will prevent your system from running correctly. Thermostats that are broken, outdated, requiring new batteries, or blank can affect your unit.

Air filter: You need to clean or change your air filter regularly so you can prevent dirt and debris build-up. Your air filters ensure that your unit has proper airflow. Your unit will not function optimally if it cannot absorb humidity. A clogged or dirty air filter will cause water droplets to freeze. When your coils are covered in ice, your unit will stop running.
