Why is Your AC Shutting Down Randomly?

Is your air-conditioning unit shutting down randomly? Well, you are not alone. This problem happens to almost every homeowner. It is called short cycling. While it is a common occurrence, you still have to worry about it.

Short cycling can waste your money. It can damage your AC unit. It can result in early wear and tear. Of course, you don’t want this to happen. You want your AC to be efficient as possible.

Wear and tear can greatly lower your AC’s lifespan. If you ignore it, you will have to fix your AC more often than you should. Next, short cycling can make your unit inefficient. This increases your energy usage and your utility bills.

If you don’t want this to happen, you need to hire a professional aire acondicionado company the moment you notice that your AC is shutting down randomly.

Today, we’re going to share with you some of the most common causes of short cycling.

Your AC is Oversized

There is a possibility that your air-conditioning unit is simply too big for the room it is trying to cool. If your AC unit is oversized, it will cool your house too quickly. Once your AC detects that the room is cool, it will shut down. Once it detects that the room isn’t cool enough, it will turn on again.

This isn’t ideal since your AC is constantly turning on and off. This makes your unit inefficient. It can result in higher energy usage and major wear and tear on your unit.

Refrigerant Leaks

Nowadays, modern compressors come with a fail-safe if they detect low-refrigerant pressure inside the system. The compressor can detect if the pressure in the system drops. If this happens, it will shut down automatically. The pressure will start to increase again once it shuts down. If the compressor detects enough pressure, it will turn on again.

To make things simple, the compressor will not work if the system has low pressure. This can happen if there is a refrigerant leak inside the unit. It can result in short cycling.

Clogged Air Filter

Your air-conditioning system will absorb warm air from your house, cool it down, and send it back to the room. Since our air is filled with dust and debris, people use an air filter to block excess dust. Over time, this air filter can get clogged with excess dust. If this happens, it will limit the supply of air that your unit absorbs. The coils will begin to freeze over if warm air isn’t getting in. This can result in short cycling.

Location of Your Thermostat

The job of your thermostat is to detect the temperature of your room. If the room is too cold or too warm, it will send a signal to your AC unit. Your thermostat can’t take a precise reading of the temperature if you place it in a location that has a different temperature than the rest of the room.

That is why your AC unit will receive mixed signals. This can result in short cycling. You should avoid installing your thermostat close to a door that leads outdoors, near a window, or under a vent.
