Why Your Air Conditioning Won't Turn On: Common Reasons


Summertime can be hot and uncomfortable without a properly working air conditioner. And, what's worse is when your air conditioning system seemed to be working fine but now won't turn on. When you are trying to cool your home on a hot day, a broken or non-functioning air conditioner can put a damper on things. There are several reasons why you may be experiencing this issue. In this blog, we'll outline some common reasons why your air conditioning won't turn on.

Incorrect Thermostat Settings

A thermostat issue is one of the most common reasons for an air conditioner not turning on. It may sound simple, but make sure you set the thermostat to the right temperature and the "on" position. Look at your user manual to ensure you are using it correctly. The problem could be related to the programming settings if it's a programmable thermostat. Resetting it or changing the batteries can solve the issue.

Dirty or Clogged Air Filters

It's important to remember that air filters need to be changed regularly. If they become clogged or dirty, airflow to the evaporator coil can be blocked, preventing the system from functioning correctly. When this happens, the air conditioner may not turn on or could blow warm air. Check your air filters and change them as necessary.

Refrigerant Leak

Refrigerant is a vital component of air conditioning systems. If your system lacks refrigerant, it could prevent the unit from turning on. This is because the refrigerant plays a significant role in cooling the system. A refrigerant leak could have serious consequences, not only to the functionality of your system but also to your health. Call a professional HVAC technician immediately to examine your system if you detect a refrigerant leak.

Faulty Electrical Connections

An air conditioning system has several electrical connections that help it operate effectively. However, if these connections are not working correctly, it can lead to problems in the system itself, such as an air conditioner that won't turn on. It's important to ensure that all electrical connections are secure and working as they should. Call an HVAC technician if you notice any frayed wires or loose connections.

Broken Components

If your air conditioner has been in operation for some time, it's common for parts to wear out and break down. A faulty compressor, for example, can prevent the unit from running altogether. Similarly, a damaged fan motor may prevent the system's blower from working correctly. If you believe that issues related to broken components are responsible for your air conditioner not turning on, call an experienced HVAC technician.

There are several reasons why your air conditioner may not be turning on, from faulty electrical connections to broken components. It's important to address these issues immediately before they lead to costly damage or further problems. Always rely on the guidance of a trained HVAC professional to perform repairs to your system effectively. Schedule regular AC maintenance to keep your air conditioning system functioning optimally.
