    James Renfroe
    I'd definitely recommend this company.
    I am very pleased with the service we received from Legacy One. Karl was a straight shooter and didn't BS us. He was honest and earned our trust during the initial consultation. His price wasn't artificially inflated. We decided to go with him after multiple price quotes and his team was great. The install went perfectly and the work was done right the first time. I'd definitely recommend this company for any HVAC needs.

    Great Team
    Great team. From the bid to installation. Considerate. Cleaned up when done. No surprises.

    I trust them
    I have used Legacy One Heating for years because I trust them. They are honest & upfront and don't try to upsell you on something that is not needed. I manage over 100 doors in Snohomish County and they are the heating vendor I send all my repairs & maintenance needs to.
    Tina Beck
    A+ Technician!
    Casey arrived on time and did a great job getting my furnace running again after it failed. A+ technician! Service was fast, reliable, and painless.
    Julia Nolan
    Professional and Personable Service
    I submitted a Yelp request for annual heat pump/gas furnace maintenance quotes on Friday and received 4 responses, all from 4+ star providers. Legacy One Heating was having a special offer of ~$100 off, and I gave them a try. I requested and immediately received detailed info on their maintenance checklist. My appointment was set for the day I asked for, Tuesday, 4 days later. On Tuesday, I got a message that the technician was on his way. He was scheduled for 10am-noon. He arrived at 10:20am and took a little over an hour to complete his tests. He was professional, personable, and knowledgeable. He offered to explain any facet of my HVAC system multiple times to make sure I knew he was open to anything I wanted. I give them 5 stars because they did exactly what I wanted, they did nothing wrong or negative, and I cannot think of anything they could have done to do a better job.

    Excellent Response Time
    Great experience today when service was urgently needed. The response time was excellent and the tech was so professional, competent, patient, diligent, and kind. My 37-week pregnant wife now has AC again... so it's all smiles here!
    Andrew Barfoot
    5 Star Service
    5 star service. Scheduling was smooth, servicing was perfect. The technicians were very knowledgeable and respectful of our house. There is apparently a special going on these days, great value! Highly recommend.
    Rajarshi Singh
    Prompt and Professional
    Ty was prompt and professional. I would definitely use Legacy One again.
    Mary Austin (Mary)
    Refreshing customer service
    Wow, it was very refreshing to get good old customer service. I was able to interact with two service techs, both of whom were very positive. After talking with them, I could tell they were happy working at Legacy One and had good support from their management. I didn't feel rushed, and they took time to double-check whether a part that had been ordered would address an issue that was discovered during routine maintenance. They took extra time to make sure the furnace was working and we were happy. I will be calling Legacy One for any AC/furnace needs in the future.
    Tim Washington
    Highly Recommend Kat
    Kat the project manager was excellent. I had a few installation problems. However, Kat wouldn’t stop until I was 100% satisfied. Highly recommend. Ask for Kat.
    Colette Piercey
    Very Professional Company
    Very professional company that went above and beyond their competitors! I contacted 5–6 HVAC companies looking to work with a reimbursement process via our home warrantor. Legacy One was the only company that was willing to work with us, which required an additional phone call to our warrantor to obtain an authorization code. The techs were very punctual, professional, and communicative. In sum, we are quite pleased with them and will be returning again next year!
    Pietro Paparella
    Great Value and Friendly Team
    Legacy One is a great value and their team is always very friendly and helpful.

    Very fine support and delivery from Mikell. Will use the company again in the future. Can recommend.
    Adam MacDonald
    Great company that gives back
    Legacy One Heating has been wonderful. I am the Facility Manager for PAWS in Lynnwood. Not only were they on time and professional, but they did the install in one day. To top it off, they donated the work and the AC unit to PAWS at no cost! Legacy One Heating is a great company that gives back to the community. I would highly recommend them. PAWS can't thank them enough for all the help they give us with all our HVAC needs.
    Mike Kanouff
    Responsive to calls/questions/etc.
    They installed our heat pumps two years ago. The initial process was smooth, and the yearly maintenance they've done has been too. Very responsive to calls/questions/etc.
    Lauren Wilde
    Super quiet and comfortable
    I wanted a quote to add a heat pump/AC to my existing HVAC system. Karl came early to quote the job, talked me through placement concerns (hooray noise ordinances) and was upfront about possibilities and remediation if there was an issue with inspection. Additionally, my existing furnace was short cycling and Legacy One provided a great deal on the full package of a heat pump and a new two-stage variable speed furnace. Install was smooth and fast, and the crew fixed an issue with how the previous furnace was vented. The heat pump was installed where I wanted it, is super quiet, and keeps the house comfortable during the days where it would have been 85+ inside. 5 stars, have recommended them to multiple friends.
    Jon Meuzelaar
    Highly Professional and Thorough
    From the first appointment, Karl (the owner) was very thorough. At the initial visit, he (among three different companies) was the only person who checked my electricity capacity to ensure it could support the unit. Laura (the operations manager who scheduled and sent me LOTS of info for the permit, etc.) was very courteous and timely every single time. On the installation day, Lonny, Casey, and TJ were very professional, making sure to keep my place clean throughout the whole day. I would recommend Legacy One Heating, Inc to everyone! Thank you for your great work.

    Service, Quality, and Value!
    I am "in the trade," so to speak... meaning I know something about HVAC. I, however, did not wish to install our new AC myself... too old for that now. I got 3 other companies to get me a quote for installing AC in our existing forced-air system before Legacy One. To be honest, by the time Legacy came along, I was pretty frustrated with the others. I like to 'play dumb' just to see what kind of unnecessary work was going to be pushed. Some of the sales pitches were kinda scary, to be honest. Two of them wanted to walk the entire house and "count floor and ceiling registers" so they could determine what AC unit would work best. (That's actually pretty funny, btw) I played along... When Legacy came along, everything the estimator said was spot-on. Nothing was pushed that wasn't necessary. When he was finishing, I asked if he wanted to walk the house and count the registers... he chuckled a bit and said no. I stated that I had heard that it was necessary to determine if our system was 'sized properly.' I love his response (probably 100% verbatim): "During the winter, does your furnace do a good job of heating your house?" to which I said "yes"... he then said "I think you're good then." Priceless. We couldn't be happier with the service, quality, and value! As a matter of fact... we now have 3 other family and friends that have had Legacy One install AC for them as well based on my experience. The only downside? No referral bonus? haha (that's OK, I'll still refer people!)

    Great Heating Company
    Legacy Heating in Mukilteo is a really great heating company. Last year they installed my new unit and this year they called to remind me it was time for my first free annual check-up. The technician was like having a neighbor in my house, what a really good experience. Yes, I absolutely recommend Legacy One Heating for your heating needs.
    Terry Boaz
    Great furnace maintenance visit
    Had a great gas furnace maintenance visit from Casey. He took his time, was thorough, friendly, and even diagnosed and fixed a wiring issue that previous visits from other companies hadn’t addressed. Also replaced my filter for free. I’ll definitely be using Legacy One again for my maintenance needs. Thank you, Casey!
    George Perantatos
    Company Committed to Customer Service
    This company is great. Everyone from the initial bid to the install and a recent warranty issue has been awesome to work with. All the employees we dealt with were super responsive and positive. The owner, Karl Christensen, is obviously deeply invested in his clients and employees. It’s great to see a company still committed to customer service and backing up their staff. Would recommend 100%.
    Justin Howell
    Awesome service and very reliable!
    Honest!! That's a huge thing for me. Did not charge extra to come out on New Year's Day and didn't try to upsell us, Karl took the time to explain our system to us and make suggestions for future maintenance on our schedule unit in the spring. Awesome service and very reliable!
    Jen Behrendt
    Fairly Priced and Professional
    Karl put in a brand new York furnace and a heat pump in our split-level home and we can't believe we waited this long! Karl is fairly priced, is personable and professional, and always showed up when he said he would and communicated throughout the process. I wouldn't hesitate to recommend him to anyone looking for an HVAC company.
