AC Frozen Evaporator Coil – A Customer’s Guide to Understanding the Issue

Hi there! It’s your pals at Reliable Appliance & HVAC, and we’re here to help you understand all about AC frozen evaporator coils. Have you ever noticed that your air conditioning unit isn’t blowing as cool or is making strange noises? That could be a sign that your evaporator coil is frozen. Don’t fret, though – we’ve got you covered. Let’s dive into everything you need to know about this HVAC issue, and how Reliable Appliance & HVAC can help you out.

Meet Our Customer – Jane from Los Angeles

Our recent service call was from Jane, a homeowner in Los Angeles with a central air conditioning unit from a major brand. She’s been experiencing issues with her AC and was hoping to get it fixed before the heat of summer really kicks in. She noticed that her unit was blowing warm air instead of cool, and there was a strange hissing sound coming from her ductwork. Worried and uncomfortable, she decided to give us a call.

What is an AC Frozen Evaporator Coil?

When your AC unit is working properly, it has an evaporator coil that is essential to the cooling process. The coil absorbs heat from the air and sends it to the outdoor unit to be released. However, when the evaporator coil becomes too cold, moisture in the air can freeze onto the coil, creating a blockage that prevents the unit from cooling properly.

How Reliable Appliance & HVAC Can Help

When Jane reached out to us, our team quickly went to work diagnosing the issue with her AC unit. Our technicians ran a complete diagnostic and found that her evaporator coil was, in fact, frozen. They also discovered that her air filter was dirty, which may have contributed to the issue. Luckily, our technicians were able to defrost the coil and clean the filter, getting Jane’s AC unit working like new again. She was so happy with our speedy service and professionalism that she left us a glowing review.

What Local Companies and HVAC Technicians Recommend to Prevent AC Frozen Evaporator Coil Issues

As we all know, an AC frozen evaporator coil is a common issue that many homeowners face during summer. A frozen evaporator coil can lead to an under-performing AC system or even a complete breakdown, which is why it’s vital to take preventative action. In this article, we’ll share preventive actions recommended by manufacturer, local companies, and HVAC technicians.

Maintain Clean Air Filters

Regularly changing your air filters is one of the simplest and effective ways to avoid an AC frozen evaporator coil. Air filters are responsible for capturing dust, dirt, and other materials to prevent them from circulating in your AC system. But dirty filters can hinder the airflow and lead to the evaporator coil freezing over. Manufacturers and HVAC technicians recommend replacing air filters every one to three months.

Keep the AC Coils Clean

Dirt and debris that accumulate on the coils can block the airflow and cause the evaporator coil to freeze over. It’s recommended to clean the coils at least once a year, preferably before the start of the summer season. Local companies and HVAC Technicians have specialized coil cleaners that can effectively remove dirt and debris.

Check for Leaks in the Ductwork

An AC system’s ductwork is responsible for carrying the air from the unit to your home. Leaky ductwork can cause the cold air to escape, leading to reduced airflow and a frozen evaporator coil. It’s important to inspect and seal the leaks in your ductwork if you notice any reduction in cooling efficiency.

Schedule Regular AC Maintenance

Regular AC maintenance, which includes cleaning, inspecting, and repairing or replacing faulty components, is essential for keeping your AC running efficiently. HVAC technicians recommend scheduling maintenance once a year, preferably before the summer season begins.

Ensure Proper AC Sizing and Installation

Lastly, improper AC sizing and installation can cause the evaporator coil to freeze over. When the unit is oversized or undersized, it can cause reduced airflow, leading to issues with the AC system. To avoid these issues, it’s essential to hire a reputable HVAC contractor to properly size and install the AC unit.

In summary, preventing an AC frozen evaporator coil requires regular maintenance and inspections of your AC system’s components. Manufacturers, local companies, and HVAC technicians recommend regularly changing air filters and cleaning the coils. Checking for leaks in your ductwork, scheduling regular maintenance, and ensuring proper sizing and installation of your AC unit can also prevent this issue.
