What’s Causing Your AC Unit to Break?

For those of us living in a hot climate, an air conditioning unit is essential for comfortable living. With no other way to cool down the inside of your house, living with a broken AC unit can be uncomfortable and even dangerous to the health of you and your family. 

If your AC unit is consistently breaking down, you need to figure out the cause to prevent further damage. In this article, we’ll go over some of the common malfunctions that could be causing your AC unit to break down and help you find an AC fix in Port St. Lucie. 

Dirty Air Filter

As your AC unit pulls in air from the outside of your home, it is also pulling in everything that is in the air. Any dust, dirt, or bacteria in the air is removed when it hits the air filter in your AC unit, which ensures the delivery of fresh, clean air into your home. 

If your AC unit air filter has become dirty or clogged, this can cause your AC unit to break down. When your air filter gets clogged, your AC unit has to work harder to pull in air. The increased demand on the AC unit can cause it to overheat and break down, leading to the need for an AC fix immediately. It can also cause parts of your AC unit to wear out more quickly than usual, which can also cause a breakdown. 

To avoid issues with your AC unit air filter, you should aim to replace your air filter once a month during the summer months. 

Sensor Malfunction

Your AC unit constantly monitors the temperature of the air entering your house using a sensor. This sensor is usually located near the evaporation coils inside the AC unit. When the AC unit pulls in air, the sensor measures the temperature of the air and compares it to the reading on your thermostat. If the air isn’t cool enough, the sensor tells the AC unit, which cools the air down to the right temperature. 

A sensor malfunction in your AC unit can cause a number of problems. It can cause the AC unit to not work properly, either under cooling or overcooling the air entering your house. This can cause the AC unit to turn on more frequently or less frequently than it should and will lead to undesirable temperatures in your home. 

This means your AC might be working harder than it needs to, which can shorten its lifespan and lead to a premature replacement of the unit. If the sensor breaks completely, this can cause your AC unit to stop working completely. 

Dirty Evaporation Coils

The evaporation coils in your AC unit are used to cool the air that passes through the unit. As the air passes over the evaporation coils, it removes heat from the air and cools it. Since the evaporation coils are located in the AC unit that is outside, they are constantly exposed to dirt and dust. 

As dirt and dust collect on the evaporation coils, it makes the AC unit less efficient. The dirt and dust serve as a barrier between the coils and the air, which makes it harder to cool the air. This means that your home will take longer to cool down and may not cool down properly at all. 

The layer of dirt on the coils can also cause your AC unit to work harder to bring in and cool down air which can cause it to overheat and breakdown. This can also cause moisture to build up on the coils, which can cause the formation of ice. The formation of ice can restrict airflow and it can also cause the AC unit to break due to the accumulation of ice. 

Live in Cool Comfort

If you’re living with an AC unit that keeps breaking down or doesn’t work properly, you can’t live comfortably during the summer months. You need to contact an AC maintenance professional who can help you address the issues with your AC unit and get you back to living in comfort.
