Furnace Tune-Up & Maintenance from Zinsmeyer Air Conditioning & Heating

Have you had your home's or businesses furnace maintained this past year? As a Armstrong ProTeam member here in the San Antonio area we have the certified furnace experience you can trust. We recommend getting your furnace tuned up at least once a year for the best operation.

It's important to note that a furnace tune-up should only be performed by a qualified HVAC professional like the ones on our staff, to ensure the safety of the homeowner and the proper operation of the furnace.

A tune-up for a gas furnace typically includes the following steps:

  • 1. Safety check: The technician will inspect the furnace for any potential safety hazards, such as gas leaks or cracks in the heat exchanger.
  • 2. Cleaning: The technician will clean the furnace and surrounding area, removing any dust or debris that could impede proper operation.
  • 3. Inspection: The technician will inspect the various components of the furnace, such as the burners, heat exchanger, and blower motor, to ensure they are in good condition.
  • 4. Adjustments: The technician will make any necessary adjustments to ensure the furnace is operating at peak efficiency, such as adjusting the air-fuel mixture, the combustion process, and the blower speed.
  • 5. Testing: The technician will test the furnace's operation and safety systems, such as the flame sensor and high-limit switch, to ensure they are functioning properly.
  • 6. Maintenance: The technician will perform any necessary maintenance, such as lubricating moving parts and replacing air filters.
  • 7. Visit Report: Our technicians will provide a written report of the tune-up and any recommendations for future maintenance.
