A walk through some of the work that's left the shop over the last 18 months — heat-pump retrofits, mini-splits in old craftsmans, a commercial RTU job, and a few IAQ retrofits. Every job lists the exact equipment, timeline, and warranty.

We don't publish every job — only the ones where the homeowner said "yes, write it up." Three have full detail pages with timeline and equipment specs. The rest are summary cards with the headline numbers.

Five-star average across 400+ Google reviews. We’re happy to email full reviews—or just call the neighbor whose house has our yard sign and ask.
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.
Ramon V.
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.
