Air Conditioning Repair Tips: All About Frozen Coils

As a homeowner, you’re likely to invest in an air conditioning installation to keep your rooms cool and comfortable. But what happens if a malfunction happens and you are suddenly left with a frozen air conditioner? One thing is for sure: you will need air conditioning repair to keep the problem from getting worse.

Frozen evaporator coils are a serious indication that something’s not right with your air conditioning system. Ignoring the issue and not calling for air conditioning repair service right away could make your compressor burn out.

Signs Your AC has a Frozen Evaporator Coil

Air Conditioning Repair Tips All About Frozen Coils1If you suspect issues with your AC, you may want to check for signs of freezing evaporator coils. Below are things you need to do when checking:

  • Look for ice forming around the outdoor refrigerant line.
  • Check if there are condensation and moisture around the air handler.
  • Inspect the condensate drain pan. Is it overflowing? If yes, is the drainpipe clogged?
  • Search for ice and/or condensation by opening the air handler and looking at the evaporator coil.

If your HVAC system starts to exhibit the above symptoms, it’s extremely important to schedule an air conditioning repair service. A frozen evaporator coil is never a good thing, so calling for central air conditioning repair is the first thing you should do when you spot a freezing AC unit.

Once you have determined that the evaporator coils are frozen, turn off your system at the breaker box. Allow your coils to defrost while waiting for a certified professional to properly check the unit and start fixing the problem.

Fixing Frozen AC Evaporator Coils

There are many potential causes for frozen evaporator coils that require help from a trained technician. Below are examples of repairs conducted by your local HVAC contractor to restore your coils to its optimal state.

1. Drain Clogs

If the condensate drain pan and lines get clogged, extra moisture can creep into your system which could lead to freezing coils. Your technician works by clearing the drain pan and lines of any clog that result in moisture back-up.

2. Refrigerant Leak Inspection

Your refrigerant system will be checked by the technician to see if there is any leak coming from it. Repairs are made and your system is charged properly to keep the issue from occurring again.

3. Cleaning Coils

Most of the time, dirty coils prevent your system from conducting a proper heat exchange, which may be the reason behind those frozen coils. The technician will get rid of any dirt and grime from the coils to allow proper heat exchange for cooling.

4. Duct Repair

The ductwork that gets damaged may keep air from moving through the AC unit. Your HVAC company will replace or repair any faulty ducts to reduce the chances of coil freezing.

It’s worth remembering that taking care of your AC unit with a preventive maintenance plan is more cost effective than spending a lot on costly air conditioning repair services. Proper maintenance also makes sure you can relax and focus on more important things, knowing your home is cool all year round.

There are many air conditioning repair companies out there, but you’ll want to find one that can offer high-quality services without ripping you off.
