Three of the most common problems HVAC units have that require a repair are:

  1. Dirty or Clogged Filters: Dirty or clogged filters can restrict airflow, reducing efficiency and putting strain on the system. This can lead to overheating and potential damage to the furnace or HVAC unit.
  2. Ignition or Pilot Control Problems: Issues with the ignition or pilot control can result in intermittent heating or no heat at all. This may be caused by a faulty ignition system or thermocouple.
  3. Thermostat Malfunctions: Problems with the thermostat, such as inaccurate temperature readings or a malfunctioning sensor, can lead to heating or cooling issues.

Michael arrived as scheduled, listened to the concern, and got right to work to solve the issue. Our heat was back up and running in less than 30 minutes and he explained what happened and what to do going forward to avoid the issue again. Thank you
