Home Service Agreements

Take advantage of our home service agreements to make sure your HVAC equipment is always in top shape.


  • Under a Home Service Agreement (HSA), you will receive 2 maintenance inspections per year (ideally this means 1 maintenance in the heating season and 1 maintenance in the cooling season).
  • By signing up as an HSA customer, you will receive 15% off parts if a repair to your system is needed.
  • You never have to worry about being charged overtime, even on the weekends or holidays. As an HSA customer, you will always be treated as a priority customer.
  • During each HSA inspection, your filters will be changed (standard 1-inch filters).
    • We recommend changing these filters on your own, as well. Filters should be changed on a monthly basis, and even more often if your home has a high traffic volume or several pets, or if you live on a gravel road.

HSA inspections will follow industry-recommended procedures and will include the following checklist as applicable to your system:

    • Clean and treat drain pan, line, switches, and pumps
    • Check refrigeration charge
    • Inspect, clean, and replace 1” filters
    • Inspect ductwork
    • Inspect and clean coils (min. 1 time per year)
    • Check and lubricate motors and bearings
    • Check defrost controls
    • Inspect indoor blower wheel
    • Check and tighten electrical components
    • Check voltage and amp draw of motors
    • Inspect safety controls for proper protection
    • Test gas valve operation (gas furnace)
    • Check and clean burner section (gas furnace)
    • Clean and inspect heat exchanger (gas furnace)
