HVAC Company in Martha Lake, WA
Dalton Heating & Air is the HVAC company Martha Lake homeowners call when the heat pump stops cooling in August or the furnace won’t fire on a January morning. We’re a Garrison Partners company held to The Garrison Standard since 2003, which means every job gets a written price before any work starts and a written guarantee on every repair. Martha Lake’s mix of 1980s and 1990s split-levels and newer townhome developments means we see a lot of aging equipment in tight mechanical closets and crawlspaces. If you need AC repair, heat pump installation, or furnace repair in Martha Lake, call (361) 306-9515 and you’ll get a live person, not a voicemail queue.
Why Martha Lake Homes Are Different
Martha Lake sits in a pocket of Snohomish County where the weather does real work on HVAC equipment. Summers regularly push into the mid-80s, and winter nights dip below freezing often enough that a dead furnace is not something you wait on. Homes here run the spectrum: 1970s ramblers near the lake itself, mid-80s split-levels along the ridges east of I-5, and newer two-story builds off 164th Street SW. The older stock tends to have undersized ductwork and electrical panels that were never meant to carry a modern heat pump. The newer developments, particularly around Martha Lake Park and the neighborhoods west toward Mill Creek, often have high-efficiency systems that were installed quickly during construction booms and need their first major service now.
Moisture is the other factor. Martha Lake’s proximity to the water and the heavy fall and spring rain seasons mean outdoor condenser units take on more leaf litter, pine needles, and standing moisture than systems in drier parts of the county. That leads to slower heat exchange, more corrosion on contactor points, and more clogged condensate drains. None of it is complicated to fix, but it has to be caught early or it turns into a compressor failure or a frozen evaporator coil.
Our Main Martha Lake Services
Three jobs make up the bulk of what we do in Martha Lake: getting a failed AC unit cooling again, replacing an old furnace, and putting in a heat pump that handles both. Each has its own page with pricing, timelines, and what to expect:
AC Repair in Martha Lake
When a Martha Lake AC quits in July, the usual culprits are a failed capacitor, a refrigerant leak, or a condensate drain that backed up from spring debris. We stock common capacitors, contactors, and fan motors on our trucks, so many repairs finish on the first visit. For anything involving refrigerant, we find the leak before we add a pound of anything. That’s the difference between a repair that holds and one that leaks again by September.

Heat Pump Installation in Martha Lake
Heat pumps are a good fit for Martha Lake’s mild winters and increasingly warm summers. The job starts with a load calculation based on your home’s square footage, window orientation, and insulation, not a rule of thumb. Then we size the outdoor unit and air handler to match, run new line sets where the old ones are undersized, and set the thermostat to actually use the heat pump correctly. We install Trane, Lennox, Goodman, and Rheem systems, and every installation includes a written fixed price before we order equipment. Read more on Heat Pump Installation in Martha Lake.

Furnace Repair in Martha Lake
A furnace that won’t light in Martha Lake is usually one of three things: a failed igniter, a dirty flame sensor, or a gas valve that’s not opening. We diagnose those in order, with the price in writing before any part gets replaced. Older furnaces in Martha Lake’s 80s-era homes often have cracked heat exchangers by now, and that’s a safety issue we won’t patch and walk away from. We’ll show you the crack, explain your options, and let you decide. Details on Furnace Repair in Martha Lake.
