Every home is different. We match the right furnace type to your space, ductwork, and budget.
The most common heating system in the Pacific Northwest. Modern gas furnaces reach up to 98% AFUE, meaning nearly every dollar of gas becomes heat for your home.
No gas line? An electric furnace delivers reliable heat with a simpler installation. Lower upfront cost, no combustion, and no CO risk. A solid choice for all-electric homes.
Pairs a new gas furnace with a heat pump. The heat pump handles mild weather efficiently; the furnace takes over on the coldest days. The best of both worlds.
Replacing both your furnace and AC at the same time? One install, one crew, one invoice. Matched systems run more efficiently and qualify for the best warranties.
We keep the process simple. Most replacements are completed in a single day.
We visit your home, assess your current system, and recommend the right furnace for your space and budget.
You receive a detailed, no-surprise quote with equipment specs, labor, permits, and any available financing options.
Our crew removes the old unit, installs the new furnace, connects everything, and tests the system top to bottom.
We pull the permit, schedule the city inspection, and walk you through your new thermostat and warranty details.

"Our old furnace finally gave out mid-January. Next Phase had a new one installed the next day. The house heats evenly now and our gas bill dropped by a third. Couldn't be happier."
"They showed me exactly why my 22-year-old furnace wasn't worth repairing. No pressure, just honest numbers. The new system is so quiet I forget it's running."
"Professional from start to finish. They removed the old unit, installed a high-efficiency Carrier, pulled the permit, and cleaned up by 4pm. One day, done right."
"We went with a dual-fuel setup. Heat pump most of the year, gas furnace kicks in on the coldest days. Our energy costs are noticeably lower and the house stays perfectly comfortable."
"Got three quotes and Next Phase was the most thorough. They explained the difference between single-stage and variable-speed, and helped me pick the right fit. No upselling."

If your furnace is over 15 years old, needs repairs costing more than half the price of a new unit, or has a cracked heat exchanger, replacement is usually the smarter investment. We'll assess your system and give you an honest recommendation.
Most furnace replacements are completed in a single day. We arrive in the morning, remove the old unit, install the new one, and have heat running by the afternoon. Complex jobs with ductwork modifications may extend to two days.
We install Carrier, Trane, Lennox, Bryant, Goodman, and other major brands. We'll recommend the best option based on your home's needs, your budget, and warranty coverage. We're not locked into one manufacturer.
