Heat pump installation in Bothell means working on both sides of the King-Snohomish county line, and we do. As a Mitsubishi Electric Diamond Contractor, we size Hyper-Heat and ductless systems for 1970s ramblers, new townhomes and everything between.
The median home here dates to 1992, but the mix is wide: large 1970s and 1980s ramblers, houses set up legally as condos, and brand-new townhomes. Any of these make a heat pump worth pricing:
If your rambler has forced-air ducts in good shape, one ducted heat pump can stand in for both the furnace and the AC.
Heating with electric baseboards? Ductless heads can take over room by room and cool in summer too.
Ductless heads suit shared-wall homes, with one extra step: line sets and outdoor unit spots usually need HOA or condo board approval first.
On June 28, 2021, Weather Service records showed Bothell at 109°F, tied for the area's high. A heat pump adds cooling without a second system.
Mobile homes make up about 6% of local housing. A heat pump on the existing ducts can carry most of an electric furnace's work.
Much of the heating season here sits in the 40s and 50s, where an inverter heat pump runs slow, steady and efficient.
Then a dual fuel add-on, or simply a tune-up, may be the smarter move, and we’ll say so. Pricing only a furnace or AC? Visit our HVAC installation page.
Ducted Mitsubishi Hyper-Heat: the SVZ air handler comes apart to fit tight closets or attics and mounts upflow or horizontal, then heats and cools the whole house through your existing ducts.
Ductless mini-split: wall heads, floor consoles or an EZ FIT ceiling cassette tucked between joists, each zone set on its own. It suits shared-wall homes where adding ducts isn't practical.
Dual fuel: PSE supplies gas on both sides of the county line, so Mitsubishi intelli-HEAT can join your furnace and be set to favor efficiency.
Use the calculator for Good, Better and Best installed figures from our actual price book, with no email required. Our free home visit then narrows that range to one firm number.
Mitsubishi says its Diamond Contractors know how to correctly size and install every ducted and ductless indoor option. Your Mitsubishi system gets 12-year parts coverage.
King County side or Snohomish side, we know which permit office and which utility's rebate page apply to your address.
Someone real answers 24/7, so a question about your new heat pump never waits for Monday.
“Sound Comfort Heating was able to fit us in the next day after calling. Mauro arrived on time and was quickly able to diagnose the problem with our heat pump. Friendly, knowledgeable and great pricing, couldn’t ask for more! Highly recommend!!”
“Service was awesome. Fast and efficient and Mauro was a delight to work with. I would recommend them to everyone!”
“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.”
We’re a family-owned Washington company, fully licensed, bonded and insured, and the same people who install your heat pump handle its tune-ups and repairs for years after.
We measure, calculate heat loss and check your ducts
You choose a system from written options
Permitted, installed and inspected, then explained
For condo homes, we start once your board signs off. The City of Bothell permit goes in through MyBuildingPermit.com, and L&I inspects the electrical.
Wisetack can turn a new heat pump into monthly payments; qualified buyers pay no interest for 12 months once credit is approved. Prefer a pay-later plan? Klarna is the other option.
Every install on either side of the county line carries the coverage below. Mitsubishi systems get the 12-year parts term because we’re a Diamond Contractor, and 10-year labor is standard unless you drop it to save.
From our Lake Stevens shop, the van gets here by SR 9 and SR 524 or by I-405, so you might spot it near Canyon Park or North Creek. Wave us over; we’re happy to talk heat pumps in your driveway.
By the house, not the ZIP code. Reusable ducts, the number of ductless zones, outdoor unit mounting and any panel work set the number. Real ranges are in the calculator above, and we confirm a firm price after measuring.
Work on site usually runs one to three days; multi-zone systems and panel upgrades stretch that. Condo board approval, the city permit and L&I’s electrical inspection add calendar time, so we map out the schedule with you up front.
Room by room. A Manual J heat loss sets the load, Manual S matches equipment to it, and Manual D checks whether existing ducts can carry the airflow. State design temperatures nearby run from 24°F at Sea-Tac to 21°F at Paine Field.
A Hyper-Heat unit keeps its full rated heat down to 5°F, a lot colder than a typical snow day here, and Mitsubishi guarantees operation to -13°F. We set the outdoor unit high enough to clear drifting snow so defrost meltwater can drain away.
Yes. Mitsubishi only grants the title after its multi-stage, hands-on Diamond Contractor program, then keeps us training as products change. A registered Mitsubishi system also gets 12 years on both parts and compressor; other brands we install carry 10 years on parts.
The City of Bothell Permit Center at City Hall, 18415 101st Ave NE, issues mechanical permits for both county sides, with applications through MyBuildingPermit.com. Washington L&I handles the electrical side. Addresses outside city limits on the Snohomish side go to the county. We pull the permits.
Check your electric bill first. On PSE power (King County side), see PSE’s electric resistance to heat pump conversion rebate if you heat with baseboards or an electric furnace. On PUD power, see its Heating Rebates page for ducted systems. Nothing is guaranteed.
Pay outright or spread it out. Approved Wisetack applicants get 12 months at 0% interest, and Klarna splits the cost into later payments. We’ll go over both at your kitchen table during the quote.
