Formerly Adam & Sam Brothers RepairEverett · Electric & gas furnaces
About 68% of Everett homes heat with electricity, more than any other city on our route. We repair electric furnaces, air handlers and gas furnaces from Silver Lake to the Northwest neighborhood, about 18–32 minutes from our shop.
Everett's housing tells two stories. North of downtown, Riverside, Northwest, Bayside and the streets around Rucker Hill hold mill-town houses from the early 1900s; Census estimates count about 7,400 homes built before 1940, most of them up there. South of the old city line, the annexations of 1959 to 1972 and the Boeing-era growth that followed filled Holly, Cascade View, Silver Lake and Twin Creeks with split-levels, apartments and condos. Fewer than half of all Everett homes are detached houses, and about two-thirds heat with electricity.
That makes Everett our busiest city for electric furnace work. Sequencers, heat strips, limit switches and blower motors are the everyday repairs, and we keep them on the van. Gas furnaces, which heat a little over a quarter of homes, get igniter, sensor, inducer and board repairs. Either way, we find the fault, write the price down and fix it once you approve. A replacement only comes up when repair stops making sense, and even then the old unit's age is not enough on its own to condemn it. Give us the model number from the furnace's rating plate when you call or book online; it usually tells us whether it is a closet electric unit, a downflow mobile-home furnace or a gas model, so we can pack accordingly.
In the early-1900s houses of north Everett, heat has usually changed fuel at least once. A home near Legion Park or on Rucker Hill may have started with a wood stove, moved to a gas or electric furnace in the basement, and gained baseboards in a later addition. Those basements often have tight access and old ductwork that leaks into the crawlspace. When we replace a furnace there, we look at the ducts, the wiring and the venting along with the furnace, and we tell you which of them is the real limit on comfort. Baker Heights, built as wartime housing in 1943, has its own compact layouts and similar questions.
South Everett is a different landscape. Apartments and condos make up a large share of homes, and many units heat with a closet electric furnace or an air handler. In those, a dead sequencer or a burned element is the usual fault, and the repair is quick when the part is on the van. Everett also has about 3% mobile homes, many with downflow electric furnaces that we repair and replace. Around Silver Lake and out toward Mill Creek, newer single-family homes are more likely to have condensing gas furnaces. In the older complexes near Everett Mall, closet furnaces are often on their second or third set of elements, which is normal wear rather than a sign the cabinet is finished.
Snohomish County PUD supplies Everett's electricity and PSE its gas. With so much electric heat in the city, adding a heat pump to an existing electric furnace is often the most effective way to cut a winter bill, and we check which PUD programs apply when we quote it. Everett marks the north end of the Convergence Zone, so its winters bring their share of wet, cold snaps, and the first one each fall exposes every furnace that skipped its filter change. A clean filter and an unblocked return grille are the two checks we ask every Everett caller to make before we arrive. We reach south Everett in 18 to 23 minutes off-peak and the north end in 25 to 32.

Furnace repair in Everett starts at $285. In the closet electric furnaces of south Everett, a dead sequencer is the job we write up most often, and a worn PSC blower motor is the next most likely. Keeping the electric furnace and pairing it with a heat pump outdoor unit starts at $5,250, equipment and installation included. These figures show where pricing begins in our area and are not a quote; the written estimate after diagnosis shows your exact cost, and the site visit and quote for an install cost nothing.
Starting prices for the north Seattle area, 2026. The $85 diagnostic is included in any repair you approve, and the exact price is in the written estimate before work starts.
Install prices start here, equipment and installation included, before any utility program. Multi-zone systems are priced after a visit. We do not charge for the site visit or the written quote.
Because most Everett furnaces are electric, the repair-or-replace question is often easier than people expect. An electric furnace has no heat exchanger to crack and no burner to clog, so a twenty-year-old unit with a failed sequencer or element is usually worth repairing. Replacement makes sense when the cabinet is rusted, the blower motor and several elements are failing together, or the wiring has been damaged by heat. The more interesting question is whether to add a heat pump. A heat pump can supply most of the winter's warmth at a fraction of the electricity, with the electric furnace staying on as backup for the coldest nights and the same ducts carrying air in both seasons. For gas furnaces in Everett's older houses, we look at age, heat exchanger condition and venting; past about twenty years with a major failure, a new furnace or a heat pump conversion is worth pricing next to the repair. A mobile-home downflow furnace follows the same logic, with one extra check on the floor duct connection beneath it.
Yes. South Everett and the Everett Mall area are about 18 to 23 minutes from our Mountlake Terrace shop off-peak; downtown and north Everett, around Legion Park, take 25 to 32. Pricing is the same across the city, with no extra charge for distance. A morning call, Monday through Saturday, usually means a technician that same day.
Usually, yes. Electric furnaces are simple: elements, sequencers, a blower and a few safety switches. A single failed part is inexpensive to replace and the unit can run for many more years. If you rent, we need the owner's approval, and we give the written price to whoever signs off on the repair.
Electric furnaces turn electricity into heat one-for-one, so they cost more to run than a heat pump, which moves heat from outdoors. Adding a heat pump outdoor unit to your existing furnace lets the heat pump do most of the work. We quote it in writing and check which Snohomish County PUD programs apply.
Yes. Older basements can be tight, so we look at access, ductwork, wiring and venting during the site visit, which costs nothing. The written quote explains what the new furnace needs and whether the ducts or electrical service limit what makes sense, so you can decide with all the facts.
Leave the house first, without operating switches or the thermostat. From outside, call PSE at 1-888-225-5773 or 911, and wait until they have checked and secured the line. After that, call us to look at the furnace and its gas connections and to give you a written price for any repair.
