Are Your AC Compressor Coils Freezing?

Frozen compressor coils in your AC unit are typically caused by refrigerant leaks. A proper refrigerant level and charge are essential to maintaining your air conditioning equipment and keeping your home cool. When something goes wrong, it’s important to call in a professional HVAC technician to investigate the cause of the frozen compressor coils and promptly fix it.

Wenbrooke Services offers an extensive range of HVAC repair, maintenance, and installation services, including the diagnosis and repair of frozen compressor coils caused by refrigerant leaks. If you’re experiencing compressor coil problems in your Frederick, MD home’s AC unit, we can discover where the refrigerant leak is located, make any necessary repairs, and get your AC’s performance back to normal.

How Compressor Coils Become Frozen

Frozen compressor coils are a common HVAC issue that, left undetected or untreated, can affect your AC’s ability to function correctly.

When helping to cool your home, refrigerant goes through a liquid-to-gas-to-liquid process as it passes through your AC equipment. The conversion-to-gas portion of the process occurs in the unit’s evaporator and evaporator coils where the refrigerant absorbs heat. As the gas changes back to liquid in the unit’s condenser coils, it releases that heat. In central AC systems, the evaporator coil is inside the unit. In heat pumps, it can be either inside or outside the unit.

The top five cause of frozen compressor coils are:

  1. Dirty air filters
  2. Broken fans that impede airflow
  3. Blocked condensate lines
  4. Malfunctioning thermostat
  5. Refrigerant leaks

When the heat energy inside the unit can’t be absorbed into the refrigerant, things can start to go wrong — fast! What usually happens is the return (indoor heat energy-filled) air is unable to get to the line. Since it then has no heat to absorb, it starts to get colder and colder until it freezes over.

Wenbrooke Services’ skilled technicians will analyze your Frederick, MD home’s AC unit to check for leaks and other problems that might be causing the compressor coils to freeze.

Repairing Frozen Coil Issues

Any compressor coil problem can dramatically affect your HVAC’s performance. Refrigerant leaks are particularly serious. If you notice frozen compressor coils on your air conditioner, the first thing to do is turn the unit off. If you continue to run it while the compressor coils are frozen, it will only make the freezing worse.

One of our trained HVAC technicians can then thaw out the system and get down to addressing the original cause of the problem. Whether it’s dirty coils, blocked air ducts, or low refrigerant due to a leak, they’ll handle fixing any issue that caused the frozen compressor coils in the first place.
