How to Fix a Frozen AC Unit Evaporator

HVAC Company Fixes Frozen AC Unit Evaporator

Hey there! We’re Reliable Appliance & HVAC, and we’ve got some hot tips on how to keep your cool when it comes to your air conditioning unit. Let’s talk about a common issue – the Frozen AC Unit Evaporator.

Recently, we received a call from our valued customer, Jane Smith, who lives in the heart of Los Angeles. Jane owns a central air conditioning unit from a major brand. She called us because she noticed that her AC was not blowing cold air. What’s more, she noticed a layer of ice on the unit’s evaporator coil.

When our technician arrived at Jane’s place, he conducted a thorough inspection of the unit. This included checking the thermostat, air filters, and ductwork. Eventually, he found the source of the problem – a frozen AC unit evaporator. Essentially, the evaporator coil (located inside the unit) freezes over, and this reduces or completely stops airflow. This is a common problem in central AC systems that can lead to high energy bills, damaged compressors, and more.

Our technician quickly defrosted the evaporator coil; it’s a simple process that requires access to hot water and some dry time. Once the coil was dry, he then cleaned it and checked for any damages or leaks. Lucky for Jane, there were no significant problems, and after conducting some diagnostics, our technician gave her the rundown of the work that needed to be done.

Tips to Prevent a Frozen AC Unit Evaporator from Reliable Appliance & HVAC San Diego

As the hot summer months roll in, having a working air conditioning system is more important than ever. However, one common issue that homeowners face is a frozen AC unit evaporator. When this happens, it can lead to inefficiencies in cooling, higher electricity bills, and even damage to the unit. So, what can you do to prevent this from happening? In this article, we’ve compiled a list of recommendations from manufacturers, local appliance companies, and HVAC technicians to help you avoid the headache of a frozen AC unit evaporator.

Keep a Clean Filter

One of the easiest ways to prevent a frozen AC unit evaporator is to regularly clean or replace your air filter. A dirty filter can restrict airflow, which can lead to a buildup of ice on the coils. HVAC experts recommend you check your filter at least once a month and clean or replace it as needed depending on whether it’s a disposable or washable filter.

Maintain Proper Airflow

Another way to maintain proper airflow is by keeping the area around the AC unit clean and clear of debris. A cluttered area can obstruct airflow to and from the unit causing it to work harder than it needs to get air, which can lead to icing over time. Be sure to maintain a 2-foot clearance around the outside unit and check that no leaves, grass clippings, or other yard debris have made it inside the unit.

Keep the Unit Free From Dirt and Debris

Cleaning the AC unit regularly is also key to maintaining it in good condition. Dust and other particles can accumulate over time and cover the evaporator coil, causing it to become too cold and freeze the coil. Regular cleaning using a gentle stream of water or a soft bristle brush can help prevent this issue.

Check Refrigerant Levels

Low refrigerant levels can also lead to a frozen AC unit evaporator problem. Check refrigerant levels regularly to ensure that there are no leaks or other issues that may cause loss of refrigerant. This is a job best left to professional HVAC technicians as working with refrigerant requires special tools and training.
