Your written scope for a heating or air-conditioning job in Spokane

Spokane Felts Field records 6,018.9 annual heating degree days, base 65°F, in NOAA's 1991–2020 normals. This is station climate context, not a heat-loss calculation for your house. For a furnace repair, describe the fault and ask what diagnosis supports repair or replacement. Source (read 2026-10-17).

• The equipment: capacity, efficiency rating and model, in writing
• The heating side too: Spokane's heating degree days mean the system heats as well as cools
• Gas line and venting checks if the system burns gas, as many of Spokane's homes do
• Who pulls the Spokane permit for heating, ventilation or A/C equipment installation or modification, and when the inspection is booked
• Removal and disposal of the old parts or materials
• Warranty terms on parts and labor, in writing

How does InstaBids work?

How is InstaBids different?

Each bidder appears under a stable label such as Contractor A, so you judge the work, not the brand.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.

The contact-detail filter can miss disguised contact details.
