HVAC Contractors in Washington: Prices, Policies and What Isn't Disclosed

13 hvac contractors in Washington, compared on the things you'd otherwise only learn on the phone: price ranges, deposits, warranties and payment terms. Where a business hasn't told us something, we say so.

Section 1Start with these three

Three full sheet excerpts to read first. Everyone else in this report follows in the table and the list below.

Section 2What to compare before you call

Ratings tell you whether past customers were happy. These six details tell you what you're agreeing to. Under each one is how many of the 13 hvac contractors in this report told us.

Total price and what it includes

Ask whether the quote includes permits, materials, cleanup and any equipment. A low number that leaves out part of the job isn't a low number.

Disclosed by 0 of 13 hvac contractors below

Deposit at signing

Know the amount before the first meeting. In many states a large deposit comes with legal deadlines for permits and a start date.

Disclosed by 0 of 13 hvac contractors below

Payment schedule

Disclosed by 0 of 13 hvac contractors below

Warranty: what kind and how long
