Common HVAC Repairs

hvac repairsServing areas of Bristol, Johnson City, and Kingsport TN

Nothing can ruin your day—or your week—like a breakdown of your heat pump, furnace, or air conditioner. These problems often happen during the hottest weather of the summer or extreme frigid temperatures in the winter, when these units are working at their hardest. If a single part of your heat pump, furnace or air conditioner in Kingsport is malfunctioning, this can create a domino effect that could lead to a total breakdown. Thompson Electrical Service wants to educate our customers in Bristol, Kingsport, and Johnson City as to the most common HVAC repairs we perform.

Higher utility bills can be a sign of an HVAC problem

Did you know that, according to the U.S. Department of Energy, air conditioning and heating systems account nearly half of their total expenditure on energy bills? If you notice your bills are going up and cannot identify a reason such as a significant change in the weather to cause your unit to run more often, your HVAC system could be malfunctioning and should be examined by a professional HVAC technician in the Tri-Cities area.

Here are some other common maintenance problems to look out for, and how they should be addressed:

  • Refrigerant leaks: The condensers in most air conditioners and HVAC systems use a liquid refrigerant, which is the source of the cool air that flows through your home. If your system does not have enough refrigerant, your air conditioner may be blowing out warmer air instead, failing to cool down your home. Leaking refrigerant also forces the condenser to work harder, which could lead to a failure of that part or the entire unit. The technicians at Thompson Electrical Service can fix a refrigerant leak and then refill the supply, making sure the refrigerant being used matches the exact specifications of the manufacturer.
  • Electrical control failure: Having problems with the compressor and/or fan controls of your unit? This can be a sign of corrosion in the terminals and wires within the system. Air conditioners that are powered off and on frequently are most vulnerable to this problem.
  • Dirty air filter: Regularly changing the filter in your HVAC can make a big difference in the efficiency of the unit, as well as your energy cost. Keeping your HVAC system clean means the motor does not have to work as hard, prolonging the effective lifespan of the unit. If you notice a reduced airflow from your vents, try changing the filter to see if that fixes the problem.
  • Drainage issues: If the condensation pump on an air conditioner breaks, the water will pool instead of drain as it should. This can lead to a leak, or even major water damage if the problem is not identified and addressed. Any drainage problem also will lower the efficiency and effectiveness of an air conditioner.
  • Sensor malfunction: The thermostat sensor is a key component of the HVAC system. It monitors the temperature of the air in your home, and then signals the HVAC system to turn on. A failure in the sensor means your HVAC system loses that ability to cycle on or off—or may turn on and off too frequently, which can cause extreme wear. A professional HVAC repairman in Bristol from Thompson Electrical Service easily can identify whether a sensor is malfunctioning.
