Top 5 Heat Pump Installation Companies in Western Washington

Comparing heat pump installers in this region means sorting through more than star ratings. Several long-running local names have been folded into national consolidators over the past few years, which can change how a company prices jobs, staffs crews, and handles warranty claims, even when the storefront and the technicians look the same as before. 

Checking ownership structure alongside reviews and BBB standing gives a fuller picture than either one alone. Here's how five of the region's most frequently searched heat pump installers compare on the record.

1. CM Heating

Founded in Everett in 1983, CM Heating built a long BBB history, A+ rated and accredited since 2002, before being acquired by national consolidator Air Pros USA in August 2022. On Yelp it holds a 3.9-star rating across 218 reviews. Its technicians carry NATE certification, including heat pump-specific credentials, alongside EPA certification, and the company is an authorized dealer for American Standard and Daikin equipment. 

Installs come with a 2-year labor warranty, layered on top of manufacturer coverage that runs up to 10 years on parts depending on the equipment line. Service area centers on Snohomish and Skagit counties, from Mukilteo to Arlington, with King County covered only occasionally. 

Best for: homeowners in the Snohomish-to-Skagit corridor who want NATE-certified installers backed by a national consolidator's parts and staffing network.

2. Product Air Heating, Cooling and Electric

Founded in 2017 and based in Marysville, Product Air remains independently owned by three brothers rather than part of a larger consolidator, and has grown to more than 5,000 customers as of 2026. It holds a 4.8-star rating across 294 reviews on Angi, where it carries a Super Service Award, and a 4.9-star aggregate across 760-plus reviews platform-wide.

It's also a Mitsubishi Diamond Elite Contractor, a designation fewer than 5% of contractors nationwide hold, which comes with a 12-year manufacturer warranty on qualifying equipment instead of the standard 10, paired with 5- to 10-year labor coverage. 

It's one of the heat pump installation companies in Western Washington that also handles the electrical work an install often requires through the same crew rather than a subcontractor, with permits and rebate paperwork managed in-house. Service area covers Seattle, Marysville, Issaquah, Mercer Island, and Lake Stevens across King, Snohomish, Skagit, and Island counties. 

Best for: homeowners who want a contractor that lays out the actual options, repair versus replace, one brand tier versus another, before recommending anything, and can handle any electrical upgrade the install calls for without bringing in a second contractor. 

3. Better Air NW

Founded in 2009 by two brothers in Everett, Better Air NW also remains independently, family-owned, with no acquisition on record. It holds the highest Yelp rating on this list, 4.9 stars across 496 reviews, and is BBB accredited.

It's an authorized American Standard dealer and a Mitsubishi Electric Diamond Dealer, and its technicians are licensed, though specific labor-warranty length isn't published on its site and is worth confirming directly before signing. Service area covers North King and Snohomish counties along with greater Seattle. 

Best for: homeowners who want a family-run installer with the strongest Yelp review record on this list.

4. Belred Heating, Cooling, Plumbing & Electrical

Belred traces back to 1986 as a one-man shop in Bellevue and has since grown into one of the region's larger home-services companies, now headquartered in Woodinville. It was acquired by Apex Service Partners, a private-equity-backed consolidator, in December 2021.

Its ratings diverge sharply by platform: 3.0 stars across 430 reviews on Yelp, against a reported 4.7 to 4.8-star average across thousands of Google reviews, a gap worth checking directly rather than trusting one source. It holds an A+ BBB rating with at least one documented complaint over installation-related damage and response time. 

Technicians are NATE certified, and the company holds authorized-dealer status for Trane, Rheem, and Mitsubishi, backing installs with an advertised lifetime limited workmanship warranty plus a first-year parts-and-labor window on repairs. Service area spans Bellevue, Woodinville, Everett, Snohomish, and the broader Seattle metro. 

Best for: homeowners who want a large, multi-brand installer, provided they cross-check its wide rating gap between Yelp and Google first.

5. Black Lion Heating, Air Conditioning & Electrical

Founded in 2010 and based in Kirkland, Black Lion holds 235 reviews on Yelp, with broader review aggregators like Birdeye showing a 4.5-star average across roughly 2,360 reviews and Angi listing 4.7 stars. It is not BBB accredited, and its BBB profile lists 2 complaints the business had not responded to at last check, worth weighing against its stronger ratings elsewhere.

Washington's L&I registry shows more than one licensed entity under the Black Lion name, so confirming the specific active license tied to any quote is a reasonable step before signing. The company is an authorized dealer for Mitsubishi Electric and Bryant equipment, with indoor air quality lines including Aprilaire and REME HALO. 

Best for: homeowners drawn to its strong review volume on aggregator sites, who take the extra step of verifying its current BBB standing and license directly.

Tips for Homeowners on How to Choose a Heat Pump Installation Company in Western Washington

Checking a single star rating rarely tells the full story, and Belred's split between a 3.0 on Yelp and a near-5.0 on Google is a clear example of why cross-checking platforms matters before a decision gets made. Confirm the active license directly through the Washington Department of 

Labor & Industries rather than relying on a company's own site, since more than one entity can share a similar name. 

Ask specifically whether a quoted warranty covers labor, manufacturer parts, or both, and for how long, since a "lifetime" claim on workmanship and a one-year window on repair labor are two different promises. 

Ask how a company handles rebate paperwork, whether it's filed at the time of the quote or left for the homeowner afterward. And where a company has been acquired by a national consolidator, it's worth asking whether pricing, staffing, or warranty terms changed after the sale, since that transition doesn't always show up in the reviews yet.

No single number on this list, star rating, BBB grade, or years in business, settles the decision by itself. Weighing them together, and checking who actually owns the company doing the installing, gives Western Washington homeowners a clearer picture than any one badge can.
