1925 Tacoma craftsman, never had ductwork, never had cooling. The owners had lived through the 2021 heat dome with box fans and wet towels. We installed a three-zone Mitsubishi Hyper-Heat that handles both cooling in August and supplemental heat in January — the radiators stay as the primary heat source.

Furnace died at 6am with two toddlers in the house. Mike was on the curb in 22 minutes, had the ignitor in his truck, and we had heat by 7:30. Charged exactly what he quoted.

Got three bids on a heat pump. NorthPeak was the only crew who measured our ductwork before quoting and who told us the Energy Trust rebate would cover $1,800 of it. They were right.

AC stopped cooling during the August heat dome. Same-day call, capacitor swap, $284 flat. The tech wore booties in the house and actually answered my question about MERV ratings.
