4 Interesting Things That Can Cause An AC System To Stop Working


The average individual would find it frustrating and inconvenient for their air conditioning system to stop working on a hot day. There are a variety of things that can lead to this phenomenon. However, many issues related to AC breakdowns are caused by homeowners not following through with routine maintenance. A malfunctioned AC system is a common issue, which is why individuals are encouraged to get routine maintenance before the peak of the season. The following points identify a few things that can cause a system not to work.

Thermostat Settings

This is the first thing that a homeowner should check. It is one of the most common things to cause systems not to turn on. The wrong settings are usually a matter of user error. However, it is possible for some thermostats to need repairs or a replacement, which can be done as an AC repair. An HVAC technician can test thermostats and determine if they have gone bad.

Dirty Air Filter

Some individuals do not realize how critical it is to have clean air filters in their homes. Filters are an inexpensive fix to an issue like this, and ensuring that filter changes are complete can prevent future system breakdowns. This is why it is critical to check to see if the air filter is dirty and clogged. Some modern AC systems are designed not to activate if filters are severely clogged. Air cannot push through filters that are clogged with dust. Dirty filters can lead to an AC system circulating warm air.

Refrigerant Leaks

Homeowners cannot fix this issue. It will require an HVAC professional. However, they may be able to tell if there is a leak. Individuals should not attempt to use their AC systems if they detect or suspect a leak. Doing so can lead to significant AC damage. Refrigerant is flammable and toxic. It is also impossible for a homeowner to legally purchase it. 

Frozen Evaporator Coils

It might be possible to see the frost on evaporator coils in the outside unit. This type of issue can be caused by a number of factors. It is an AC repair issue because it usually is not a one-time thing. Homeowners who do not seek repairs may damage their systems and require complex repairs.

An HVAC contractor is a good resource to use to troubleshoot a malfunctioned AC system. They can determine the appropriate AC repairs and get a cooling system restored. If the issue is something that could have been prevented by getting routine maintenance, they can advise on a future maintenance schedule.
