Swapping out a tired furnace, an oil tank or electric baseboards? Our Lynnwood heat pump installation work comes from a Mitsubishi Electric Diamond Contractor, and your price is only final after a free visit and load calculation.











Lynnwood homes run from 1950s cottages to new townhomes near the light rail station. A heat pump suits more of them than most owners expect. These situations are the ones we see most often.
Some Lynnwood houses still heat with fuel oil. A heat pump removes the tank, the deliveries and the aging burner in one project.
Baseboards turn electricity into heat one for one. A heat pump delivers far more warmth from the same power, and adds cooling.
A gas furnace near the end of its life can be replaced with a heat pump alone, or paired with one for a hybrid setup.
The 2021 heat dome pushed Lynnwood to 109 degrees. A heat pump adds real cooling for the next one, using the same equipment.
Rooms the ducts never reached stay cold or stuffy. A ductless head gives that space its own thermostat.
New living space is a chance to choose efficient equipment from the start, under the current Washington energy code.
The free visit settles it. We inspect ducts, panel, insulation and your current heat, then give you an honest answer on a heat pump, a furnace or a combination.
Ducted Mitsubishi Hyper-Heat: a cold-climate outdoor unit paired with an air handler uses your existing ductwork, so a rambler with solid ducts can stay all-electric without tearing into walls.
Ductless mini-split: wall or ceiling heads suit condos, townhomes and additions that lack ducts, each zone with its own thermostat. Multi-zone outdoor units serve several rooms.
Dual fuel: a heat pump teamed with the gas furnace you already own. The pump carries most days, and gas takes over during the coldest stretches.

Diamond Contractor status is what unlocks a 12-year parts warranty on Mitsubishi Electric installs, and it reflects the install standards behind that name.
We measure your home's heat loss before choosing equipment instead of copying the old unit's size, so comfort stays even and nothing short cycles.
Our shop sits in Lake Stevens, a short drive up US 2 and I-5, and the owner is a licensed technician who still works in the field.
“I had my 22 year old furnace replaced. I Contacted 7 total Heating companies for a bid. Out of those 7 contractors, Sound Comfort Heating is the BEST in all categories: pricing, customer experience, knowledge and same day installation. Also the installation is seamless. Super clean! Which makes us really happy. I Definitely highly recommend Marco and Carson. I am very thankful for them. I made the best decision because they are amazing.”


“Excellent Service and outcome exceeded our expectations. Highly recommend their service.”
“Hannah was awesome to schedule with! Great service all around!”

It depends on ducted versus ductless, home size and electrical work. Our cost calculator shows real ranges, and the free in-home visit makes the number firm.
Single systems often take one to three days. Multi-zone setups, new ducts or a panel upgrade add time, as do permits and inspections. You get a schedule before work starts.
We run a load calculation using your home’s size, insulation, windows and layout, then match equipment capacity to your local winter design temperature. Bigger is not better, and a properly sized unit runs quietly and steadily.
Yes. Cold-climate models like Mitsubishi Hyper-Heat keep producing heat well below freezing. Lynnwood’s wet, mild winters fall comfortably inside what they handle.
Because we are a Mitsubishi Electric Diamond Contractor, Mitsubishi Electric installs carry a 12-year parts warranty. Details are on our Diamond Contractor page.
Heat pumps normally require permits, and Lynnwood issues its own electrical permits. We look at your panel during the visit, and older homes sometimes need an upgrade that we spell out in the quote.
