Cost and timing

Rebates

Seattle's Clean Heat Program: $2,000 off for most homes that switch from oil heat to a Mitsubishi Electric heat pump. Households earning 81% to 150% of the area median income get $4,000 more, $6,000 in all. The install must be finished by May 30, 2027, by one of the program's participating contractors.

Permit value (not a price)

Their typical permit lists $18,000 (half list more, half less)

That is the figure written on the permit form, which can be far from what you pay. Over their last 12 months (11 permits) it was $22,000. Kitchen jobs alone: typical permit $30,412 (6 permits, a small sample). What heat pump jobs cost in Seattle.

Permit timeline

Across Seattle, a heat pump permit stays open about 87 days, from permit to final inspection

This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. The permit itself is usually issued the same day. How long heat pump jobs take.

Worth asking any heat pump installer

  • Can you show me proof of liability insurance and your bond?
  • What size unit, and did you measure the house to choose it?
  • Do my ducts or my electrical panel need work first?
  • Who pulls the permit, and what rebates apply?
