Have you turned on your air conditioner for the first time this year and found that your air conditioner is running, but no cool air is coming into your home? You may also have noticed that the air conditioning unit has visible ice and condensation build-up. If this is the case, then you’re experiencing a frozen air conditioner because your AC evaporator coil is freezing up. Call Colorado's most trusted hvac contractor HVAC Arvada , to keep your home comfortable in the hottest summer months.
REASONS WHY YOUR AC’S EVAPORATOR COIL IS FREEZING UPYour air conditioner’s evaporator coil vaporizes liquid refrigerant to make the air cool. These coils are supposed to be cool, but not freezing. In an optimally running air conditioner, the refrigerant vapor stays around 40 degrees. If the coils get cooler than that, they can freeze, and once they freeze, they continue to build up ice. That’s why it’s so important to turn your air conditioner off when this occurs. The most common reason for frozen evaporator coils is insufficient airflow. This is commonly caused by a clogged or dirty air filter, backed-up drain clogs, low fan speed, or a dirty evaporator coil. Check to see how many registers are closed in your home. If more than a quarter of them are closed, it could cause your evaporator coil to freeze. Sometimes low refrigerant levels and leaks are the cause of a frozen AC system. Your air conditioner could also be experiencing a malfunctioning defrost cycle. If your air conditioner cannot keep itself warm enough to prevent ice from accumulating, it means it can’t defrost properly. If you have a window air conditioner unit, make sure it’s tilted so the indoor portion is slightly higher than the outdoor half to make sure it’s draining properly. WHAT TO DO IF YOU HAVE A FROZEN EVAPORATOR COILFirst, you’ll want to turn off your air conditioner. Inspect your air conditioner inside and out for any obvious signs of condensation or ice. If there is ice, wait until it’s melted before trying to start the air conditioner again. Never chip away at the ice. Although there are some common solutions, you’ll most likely need to call an AC technician from HVAC Arvada to find the cause and make the appropriate repair or replacement.
