HVAC reviews in Seattle, Washington

Absolutely Outstanding – The Gold Standard in Home Services!I recently had Greenwood Heating and Home Services install a Generac 26 kW whole-home backup generator at our Seattle residence, and I can confidently say this was one of the best home improvement experiences we've ever had. From the initial consultation to the final walkthrough, every step was handled with exceptional professionalism, transparency, and genuine care.What truly sets Greenwood apart is their superior communication and customer service. From the very beginning, they kept us informed with clear timelines, detailed explanations of the process, and prompt responses to all our questions. No surprises, no vague answers – just straightforward, helpful guidance that made a complex project feel seamless and stress-free.The installation itself was flawless, executed by a highly skilled team. Special kudos go to Austin for his expert coordination and oversight, Carissa for her outstanding support and attentiveness throughout, and the electrical crew – Joe (the journeyman electrician) and Joseph (the apprentice) – who demonstrated incredible precision, efficiency, and respect for our home. They worked meticulously, ensured everything was clean and tidy upon completion, and took the time to thoroughly explain the system's operation and maintenance.As a family-owned company with over a century of service in the Seattle area, Greenwood exemplifies the highest level of integrity, craftsmanship, and customer focus that larger corporations often lack. They truly embody what outstanding service looks like – reliable, personable, and committed to getting it right the first time.If you're considering a backup generator (or any home service) in Seattle, look no further than Greenwood Heating and Home Services. They have earned our highest recommendation and lifelong loyalty. Thank you for giving us unparalleled peace of mind during those unpredictable Pacific Northwest storms!

Joe from Greenwood Heating did an excellent job with my electrical work. (Electrical Panel replacement). Easy to work with, on time, on schedule, quality work. I've used Greenwood for other services (HVAC) before this and had good experiences, and this just continues my assessment of them as quality service providers.

MIke is highly skilled at fixing these HVAC systems and an excellent explainer of the issue/problem.we were getting error codes in our Trane heat pump. He was great! Greenwood Heating may seem a bit pricey but they give excellent customer service. We paid $305 for the service call including when Mike had to return the next day to make sure the problem was fixed. Reasonable considering the amount of time. Thanks, Mike.

Excellent Home EV Charger Installation by Greenwood!
I highly recommend Greenwood! The entire process for installing my home EV charger was seamless and professional from start to finish.
The technicians were incredibly knowledgeable, arrived on time, and worked very efficiently. They expertly installed the ChargePoint unit—it looks clean and works flawlessly. I especially appreciated that they walked me through the system and made sure the work area was spotless before leaving.
Based on this outstanding experience, I will definitely use Greenwood for future electrical needs in the Kirkland area. Five stars for professional, reliable service!

Highly recommend Greenwood Heating. My furnace died and after not getting a response from the company I had been using for many years, I reached out to Greenwood heating based on a referral from a family member. They called me back right away and prioritized an appointment to come out and give me a bid. They worked around my schedule on the new installation and were very prompt. Bryan did the install and was great with updating me with his progress as he moved along. He cleaned up everything very well, walked me through how to work my new thermostat and answered all my questions. It was a great experience.

I literally NEVER write reviews BUT I honestly cannot say more great things about this company and those working there! Kind, respectful, efficient, timely, and very knowledgeable.

From the initial appointment with Austin to having my electrical panel replaced with Ethen and Frankie to installing a two unit mini split system with Jeremiah and Andre and plumbing assistance with Summar…along with each of their partners on the jobs… Extremely well-rounded, versatile company that has specialists for everything housing. Highly recommend their services!

Just an amazing company to work with. Had an issue with my water heater and they were happy to help and were able to make it earlier than expected and took care of the work in a few minutes. Having worked with so many companies, I can confidently say they are the best in their business. Highly recommend them.

Had the absolute best experience with Lake Stevens from Greenwood! He was full of energy and was so thoughtful, and very knowledgeable. Lake explained everything in such fantastic detail, to the point i was shocked it made sense to me. He made it really fun learning about the furnace, and His personality alone was fabulous. I couldn’t have ask for a better person to do my maintenance. I will definitely be sticking with Greenwood every year and telling my friends just because of my experience with Lake ! He Really made my year. What an amazing employee you have.

I had a great experience with Greenwood Heating and Home Services and their technician, Lake. Lake provided routine maintenance service on the furnace. Making the appointment was easy and communication was great. Lake was on time, efficient, thorough and personable. He took pictures of all measurements and adjustments before and after and walked me through the quality check of my system and the adjustments he did. I felt confident when he left that my furnace was in good shape and the adjustments he made would improve its efficiency and prolong its life. I will specifically ask for Lake in the future.

We had our furnace maintenance done by Lake stevens, and what an absolute pleasure! He was on time, so knowledgeable, and walked us through everything step by step. From the moment he pulled up, he was so excited and happy to see us, it was so sweet! He showed us, and taught us how the furnace works, and what was inside it in detailed. He made us feel so comfortable, and didn’t come off pushy at all. ( we are so used to HVAC people being so rude and mean a lot of the time) so this was a huge surprise to us. I cant tell you enough about how amazing Lake is as a person and an employee for your company. We are Greenwood customers now. ONLY IF WE GET LAKE STEVENS! lol but can’t wait to see him again to help us with our furnace for next year. He went above and beyond in every single way. Won’t ever forget this fun experience. Thank you for everything!

Great specialist. Awesome person.
Installation went perfectly — he arrived on time, worked neatly, and made sure everything was installed safely and up to code. He also took the time to walk me through how to use the charger and answered all my questions.

Updating my review since we have now had both HVAC services as well as Electrical Services from Greenwood and both were great experiences!

Muhammed came to service our HVAC system and mini-splits and did a fantastic job! We had let them go for too long between services and they were quite filthy from our two big dogs. Muhammed was timely and great at communicating what he was doing and how he’d be working.

Joe and his apprentice did a full electrical panel upgrade for us and installed a bunch of new lights and outlets for us in an area where we are remodeling. They were awesome to work with, so friendly and responsive, and it was nice to have them around for a few days!

Thanks y'all!

Jose was prompt, very professional yet very personable! He was able to answer my questions in a very understandable way. I always appreciate learning - he was just great!
Jose had to coordinate two places and my tenant was very comfortable with Jose working. He was very respectful of my tenant working and did his work as quietly as possible—a detail very much appreciated as it did not interrupt her work schedule. Jose is a great asset to your company and got me to sign in for next year. The experience for me was excellent!! Thank you Jose!

We had an excellent experience with Greenwood for a series of projects including a new electric panel, new water heater, duct cleaning and more. Everyone on the team was fantastic, from Brandon and Tomas on the electrical team, Lucas from the plumbing team, and Jose, Thuan, and John from the HVAC team, and everyone else I worked with. Everyone from Greenwood was friendly, professional, and all did a great job on our projects.

Brandon Banister and Tomas from the electrical team went above and beyond and not only handled our electrical needs such as the new electric panel, they also helped rewire our hot tub when they saw the old wire was not suitable for the hot tub’s amp requirements. You knew they wanted to do the job right and they helped make sure everything was safe and in top quality for our family.

I highly recommend Greenwood and look forward to using them again

Great service. Brody, the technician (plumber) was personable, efficient. Informative, and service oriented. He fixed an issue in addition to the one we called him out for. He went the extra mile in checking our plumbing system. We have used Greenwood for furnace services and have always been happy with their employees and service and that's why we turned to them for plumbing service. We highly recommend them!

Great and professional service. They did all of our HVAC and electrical work fast and on time. Luke gained our trust immediately when he started explaining all our appliances to us and how our furnace worked to our new home and what we should expect to change out soon. We really appreciate it. Thank you

Marcus came over to our house twice. He was on time, courteous, informative, and even took a look at another plumbing issue that we had had in the house and gave some advice. He cleaned up after the work and made the whole process feel ease comfortable. Highly recommend Marcus and Greenwood plumbing.

Had an issue with my one year old water heater. When I turned on my faucet, I got water at first, but then it dribbled to nothing. I am pretty good at figuring out problems around the house, but this stumped me. Called Greenwood. They said it would be sometime between 1 and 8 for their technician. He arrived around 2:15. After evaluating everything, it was a simple fix. The little box that sits on top of the water heater and regulates the safety valve has 4 Bain it. They were dead! When they died, the valve shut. New batteries and I had water. I knew what that box was, but didn’t know about the batteries Now I do! Great job done by Tyler Stevenson.

Ratnesh was great and super knowledgeable. He arrived same day and expertly resolved the issues. After repeated appointments with other service providers, it was a huge relief to have Greenwood Heating get things all sorted. If I ever need HVAC service again I know exactly where I’m going!

This is an update on the earlier review below.
Greenwood tech came over and addressed the issue at no additional charge. They were very professional in addressing the issue and I didn’t feel pressured. They were very thorough and polite. Love it when service companies own it and fix it. They are a class act. THANKYOU!!!!

Charged me for diagnostics which i paid; after the tech left the battery on the generator drained to 11.7v from 12.2. Within 22 hours and its useless now. I took pictures that i sent to the tech before he arrived to prove the battery was healthy. Not happy about it. The problem was with circuit breaker in panel but they offered to do a generator and electrical diagnostics for extra costs. It made the problem worst. If this problem is not corrected then the review stands and further actions will be taken.

Was incredibly pleased with Greenwood’s team, from Lori in sales, Alex and Jared (furnace/mechanical), Brandon (AC)/the electricians / the whole team! The City inspector came a few days after the job was completed and commented “they did excellent work.. no issues at all!” A+!
