Furnaces, heat pumps and air conditioning, sized to your house and priced in writing before anyone picks up a wrench.
Reading pressures before the quote, not after.
Two-stage gas furnaces / Modulating furnaces / Variable-speed blowers / Ducted heat pumps / Cold-climate heat pumps / Ductless mini-splits / Dual-fuel pairings / Air handlers / Evaporator coils / Condensers / Line sets / R-410A / R-454B / Heat kits / Condensate pumps / Flue liners / Hot-surface igniters / Flame sensors / Zoning dampers / Return drops / Supply trunks / MERV filters / and whatever the last owner left in the basement.
If it moves heat in a house, we have opened one up. Every quote names the part, the model and the reason.
Licence: WA contractor licence number, owner supplies. Bonded and insured: carrier and policy, owner supplies. We list these where you can look them up, or we do not list them.
Two-stage and modulating furnaces, sized from a room-by-room load calculation rather than the sticker on the old unit. We check the flue, the gas line and the return air before we price anything, because those three decide how long the new furnace lasts.
Ducted and ductless heat pumps, cold-climate models included, and dual-fuel setups that keep a good furnace as backup on the coldest nights. We tell you the outdoor temperature where your system hands over, in writing.
Central air on the ductwork you already have, with the line set replaced when it is the wrong size or charged with the wrong refrigerant. Tonnage comes from the load calculation, never from the house's square footage alone.
Most bad installs start with a guess. So before we price your system, we read what the old one has been telling everyone for years.
Every furnace and outdoor unit carries a rating plate. This is what we read off yours, and what each line means for your price.
No sales sheet, no ten-year financing pitch at the kitchen table. One person who does the work, and a price you can hold us to.
One technician, on time, with the truck stocked for the system you described on the phone.
First 10 minutes
We read the nameplate, test the safeties, measure static pressure and look at the flue and drain.
About an hour
You get a written price with the model numbers on it. Repair and replace side by side when both are honest options.
Before we leave
Floors covered, old unit hauled, the system started and run through a full cycle with you watching.
Booked by you
Three people run Northline. Names and photos are placeholders until the owner supplies them.
Owner and lead installer
Bio to come: years in the trade, where they trained, the kind of job they still take themselves.
Service technician
Bio to come: the calls they run most, the certifications they actually hold, the part of the work they like.
Scheduling and office
Bio to come: the person who answers the phone and books the visit, and what to tell them when the house is cold.
