Sometimes your air conditioner can appear to be running just fine, but still isn’t doing its job to cool your home. When this happens, there can be several possible causes that prevent your air conditioner from keeping you cool. We’ve listed a few below.
Ductwork – Ductwork is one of the most important components of your overall HVAC system. It is responsible for delivering the heated or cooled air, produced by your air conditioner or furnace, throughout your home. When your ductwork is cracked, bent, or poorly designed, the heated or cooled air your HVAC unit works so hard to create, cannot keep you comfortable. A thorough inspection and sealing of your ductwork may be necessary to fix the problem.
Thermostat – If you notice your AC is running, but not always cooling, you might want to check your thermostat settings. Most thermostats have an “auto” and “on” setting for the blower, and when set a certain way, can make your air conditioner seem like it’s not working properly. When set to “auto” the blower goes off and on according to the set room temperature. In the “on” position, the blower will run continuously regardless of the room temperature. Often, the “on” position is used for homes with air cleaners and other filtration systems installed as part of their HVAC system.
Refrigerant – Especially as your unit ages, it will leak small amounts of refrigerant every season if it is not charged on a regular basis. Sometimes, your unit can leak too much refrigerant to be effective at keeping you cool. In other instances, the refrigerant can come into contact with moisture and freeze, which causes blockages and prevent your unit from cooling properly. To avoid this, it’s a good idea to have your AC serviced on an annual basis.
Condenser Coils – Sometimes a stalled condenser coil can cause your unit to keep from blowing cool air. The condenser coil is the part of the unit responsible for producing cold air. A blown fuse or tripped circuit breaker can cause it to quit working while the fan will continue to run, providing the facade your AC is operating, as it should. A professional inspection if your AC will help to determine if this is the problem.
