Arlington, VA Air Conditioning Repair: Not Enough Cooling

The convenience of air conditioners is something we often take for granted. Their soothing white noise is part of the unnoticed backdrop of daily life. But you will notice if your air conditioner starts to lose its ability to lower the temperature. If the air from the vents in your home feels warmer than it once did, you might have an AC malfunction that requires repair. When you need work done on your air conditioning system in Arlington, VA, the right place to turn is Polar Bear. Our more than 10 years of experience means we are well equipped to care for home comfort systems.

Here are three common culprits that can impair your AC’s cooling ability and will require repairs:

  • Thermostat issues: The first step to take when you notice a weakening of cooling power in your AC is to inspect the thermostat to see that it is set correctly. A faulty thermostat can cause your air conditioner to turn off at the wrong times or to raise its temperature rather than lowering it. If simply changing the settings doesn’t help, then your thermostat will need repair or replacement.
  • Damaged ducts: If you have a standard air conditioner that relies on ductwork for air distribution, breaks and kinks in the ducts can lead to warmer air seeping inside. If a gap opens in a place where the air temperature is higher than the rest of your home (e.g. the attic or a crawlspace), your AC will draw in this warm air and blow it through the vents. Sealing the ducts with duct tape won’t solve this problem. It requires an expert using mastic sealant or other techniques to properly fix the damage.
  • Icing on the coils: Although you might think getting frost across the indoor coils would help with lowering the temperature, it seriously interferes with the important heat exchange across the evaporator coils and will mean less cool air. Icing often happens because of a leak in the refrigerant, although dirt on the coils can also trigger it. You will need an HVAC technician to diagnose the cause and make the repairs that will get the heat exchange back to normal.
