Frozen air conditioners may be attributed to a variety of causes.
Some minor causes of air conditioner units freezing up during the course of operation can easily be repaired by the homeowner as part of overall maintenance of the air conditioning system. Preventative maintenance plays an important role in keeping the air conditioning unit operating without problems. Some problems with air conditioning units can be more difficult to diagnose and to treat without the expertise, equipment and services of a qualified trained professional. Does this Spark an idea?
Instructions
Filter
1. Turn off the air conditioning unit to allow the frozen suction line to thaw before beginning any repairs. Use ceiling fans, box fans or window fans to maintain comfort in the house while the air conditioning unit is being serviced.
2. Central air filters are located behind these types of access panels.
Locate the air filter. It will be located on the front of the unit in window air conditioning units and may be installed on a wall, on the floor, or in the ceiling of the room in central air conditioning installations.
3. Remove the access panel which holds the filter in place by using a screwdriver if necessary. Inspect the filter for excessive amounts of dust buildup. Filters used in window air conditioning units may be washed and reused while filters for central air conditioning units will need to be replaced with a filter of the same size and type.
4. Remove the vent covers in each room if you are using central air conditioning units. Vent covers will be held in with either a straight-blade screw or Phillips blade. Use the appropriate screwdriver to remove the vent cover. Use an extended handle duster and vacuum cleaner with a crevice attachment to remove dust from the duct work.
Condensor unit
5. Use a water hose with the nozzle on a spray setting to remove debris such as dust, dirt and leaves from the condenser unit located outside the home. For window air conditioning units, this will be the portion of the unit that sticks out of the window from outside the home. Allow at least 24 hours for the unit to dry before turning power back on to the unit.
6. Turn power on the next day. Periodically inspect the air conditioning units to evaluate any freezing which occurs.
7. Freezing of the unit at this point may be due to a low amount of refrigerant in the system. Recharging the refrigerant in the system usually requires the skill of a trained air conditioning professional.
