Ready to leave an aging oil or gas furnace behind? Sound Comfort handles heat pump installation in Shoreline as a Mitsubishi Electric Diamond Contractor. We size it with a real load calculation, show you the price in writing, and install it cleanly.











Shoreline's mild, damp climate suits heat pumps well, and many homes here are ready for one. If a few of these sound like your house, a free quote is worth your time.
Heating oil is still around in Shoreline. Swapping an aging oil tank and furnace for a heat pump removes fuel deliveries and tank worries.
The postwar boom filled this area with ramblers and split-levels. Original equipment from that era is long overdue for something efficient.
Shoreline hit 105 degrees in June 2021. A heat pump cools the house on days like that, which a furnace alone never can.
Finished basements, garage conversions and additions often lack ductwork. A ductless heat pump reaches them without opening walls.
If a furnace needs another costly part every season, putting that money toward a new heat pump may serve you better.
A heat pump handles heating and cooling together, so there is one outdoor unit and one set of controls to manage.
Come as you are. We look at your ducts, panel and heating needs, tell you honestly what makes sense, and never pressure you into a decision.
Ducted Mitsubishi Hyper-Heat: pairs an outdoor unit with an air handler on your existing ducts, and holds its heating output in cold snaps well below freezing.
Ductless mini-split: wall or ceiling heads serve one room or several zones, ideal for additions, daylight basements and homes that never had ducts.
Dual fuel: a heat pump handles most days and your existing gas furnace steps in during the coldest stretches, a flexible choice for PSE gas customers.

Mitsubishi describes this as its highest level of installer training. It also unlocks our 12-year parts warranty on Mitsubishi Electric installs.
We run a proper load calculation at your home rather than copying the old equipment, so the heat pump matches your actual house.
You see a written price before anything starts. If the number changes, it is because you chose to change the scope.
“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.”
“Fantastic service. Service was quick and they kept me informed on what they were doing. Mauro was friendly and didn’t try to upsell any services that weren’t required”

Every install is handled by a local, licensed, bonded and insured team, led by an owner who still works in the field.

When our van pulls up on your street in Richmond Beach, Ridgecrest or anywhere between, you get a local family-owned crew that cares about the work. We drive down from our Lake Stevens shop, so you deal with a real team, not a distant call center.
The price depends on your home, ducts, electrical needs and the system you choose. Use the calculator above for real Good, Better and Best numbers, then we confirm them in a free in-home quote.
It depends on the system. Ducted installs, new electrical circuits or several ductless zones take longer than a single head, and we give you a clear schedule before any work starts.
We run a load calculation that accounts for your insulation, windows, square footage and the local cold-weather design temperature. We never size by simply matching the old equipment.
