Freezing Up ?
Frozen-A-C-1-300x258.jpg

 

Sounds weird – but IT IS TRUE – – Your HVAC equipment may freeze up during the middle of the summer.

BUT WHY ??

1. Insufficient air flow across your air conditioner’s evaporator coil can cause it to freeze up. An air conditioner, is designed to drop the temperature of your house by removing heat from the house. If your air conditioner is not properly blowing inside air over the evaporator coil, then this heat exchange cannot take place and the Freon aka Refrigerant..that should be removing heat from your home is not. Over time, the temperature of the evaporator coil will continue to drop and your air conditioner can freeze up.

 

2. If your air conditioner is low on refrigerant due to a leak, then your air conditioner can freeze up due to the evaporator operating at too low of a temperature. As your air conditioner’s evaporator coil drops below freezing, the moisture in your air will freeze as it comes into contact with your coil causing it to ice up.

 

3. Air conditioners are designed to function in a very specific temperature range. If you are running your air conditioner when the outside air is below around 62 degrees, then the pressures inside of your system will drop and again the evaporator coil will be operating at too low of a temperature. As your air conditioner’s evaporator coil drops below freezing, the moisture in your air will freeze as it comes into contact with your coil causing it to ice up.

 

4. Mechanical failures can cause your air conditioner to freeze up. If there is a kink in your refrigerant lines, a blower fan that is not running at all or to the proper speed, filter is clogged, evaporator coil is dirty, metering device is not functioning properly then the air conditioner’s evaporator coil drops below freezing, the moisture in your air will freeze as it comes into contact with your coil causing it to ice up.

Simply put, your air conditioner is freezing up because of the lack of heat exchange between the evaporator and the indoor air due to one of the above reasons.
