Most Common HVAC Repairs

Maybe your basement feels colder than usual or you notice that your HVAC unit continues to turn on and off. However small, these are signs that your HVAC system may require repair. Some of the most common HVAC repairs include:

  • Air Filter Replacement: If you notice that the airflow from your vents is weak, it could be due to a clogged or dirty air filter restricting airflow through the system.
  • Thermostat Replacement or Repair: When the temperature displayed on your thermostat doesn’t match the actual temperature in your home, it may indicate a problem with the thermostat’s sensors or calibration.
  • Heat Exchanger Replacement: A cracked or damaged heat exchanger can lead to carbon monoxide leaks and pose a serious health risk. Replacement is necessary to ensure safety.
  • Capacitor Replacement: When an HVAC unit stops working entirely, the capacitor is often to blame. The capacitor provides the electrical energy needed to start the system’s motors.
  • Refrigerant Leak Repair: If your AC unit is struggling to cool your house off, it could be a sign of a refrigerant leak. In some cases, the refrigerant can simply be recharged. In others, the copper coils will need to be replaced entirely.
  • Duct Repair or Sealing: Leaky or damaged ductwork can result in air loss and reduced efficiency. Repairing or sealing ducts improves airflow and system performance.
  • Fan Motor Replacement: Weak airflow usually indicates that the HVAC system’s fan motor needs to be replaced. Unusual noises, such as grinding, squealing, or loud banging, could also indicate a malfunctioning fan motor.
  • Compressor Replacement: If your AC system fails, the compressor likely needs to be replaced. The compressor’s primary function is to circulate refrigerant through the system, facilitating the transfer of heat from inside your home to the outside environment.
  • Evaporator Coil Cleaning or Replacement: Dirty or damaged evaporator coils can restrict airflow, reducing the efficiency of your AC unit. Cleaning or replacing coils can help keep your Ashburn, VA, home nice and cool.
  • Condenser Coil Cleaning: Dirt and debris accumulation on condenser coils can reduce the system’s efficiency and cooling capacity. Cleaning the coils restores optimal performance.
