Why You Need To Hire A HVAC Specialist When Your AC Keeps Freezing Up

If your commercial AC starts acting up, it can cause a major interruption to business operations. Unfortunately, there’s no way to avoid occasional air conditioner problems.

An issue that can occur in both summer and winter months is AC freezing. This typically happens when there’s a problem with airflow.

If your AC keeps freezing up, it’s important to call an HVAC specialist. Hiring a professional is the best way to get things up and running as soon as possible.

Common Causes of a Frozen Air Conditioner

Several problems could lead to a frozen AC unit. When you’re dealing with a commercial unit, these issues can be tough to diagnose and fix on your own.

Let’s go over some of the most common causes of an AC unit freezing up.

Refrigerant Leak

AC refrigerant helps regulate temperature and pressure. When a leak occurs, there’s a good chance the AC will freeze.

These leaks can occur due to friction when evaporator coils rub against each other. They may also happen if condenser coils get holes in them. Both of these problems require the help of an HVAC professional.

Dirty or Damaged Coils

The coils in an AC unit work to cool the surrounding air. Because they become very cold, warm air needs to be able to move through freely to stop them from freezing.

Coils that are either damaged or covered in grime won’t work as they should. This means your AC could freeze and stop functioning properly.

A Clogged Filter

One of the most common ways airflow gets restricted in an AC unit is dirty filters. After the dust, pollen, and other debris accumulate on the filter, a limited amount of air can pass through to the coils.

Once condensation starts building up on the coils, it’s just a matter of time before they freeze. That’s why it’s important to have regular maintenance performed on your commercial air conditioner. A professional will stop the problem before it starts.

Fan Malfunction

If the fan on your unit is having issues, this will restrict airflow. This means there’s a bigger chance of your AC freezing up.

Common issues include damage to the motor and blades, loose connections, or a burnt-out fan. An HVAC technician will need to determine if a new fan is necessary.

Consequences of a Frozen AC

If you suspect your AC has frozen, you need to call in a professional right away. Ignoring the problem could make things much worse.

Frozen evaporator coils will eventually start to damage other components of your unit. The longer you wait, the more expensive the repairs will be.

Running an AC while it’s frozen means the unit will have work harder to keep the building comfortable. This puts added strain on the unit and will cause an increase in energy bills. If you neglect a frozen AC unit for too long, you could end up with a complete breakdown.

Call the Pros if Your AC Keeps Freezing Up

The points discussed above are just a few reasons why your AC keeps freezing up on you.

If you suspect a problem, it’s important you call a commercial HVAC technician right away. They’ll diagnose the issue and make the proper repairs so you can get back to business.
