Reviews of local pros in Seattle, Washington

We chose Greenwood to replace our gas furnace and add a heat pump so we now use electric for cooling and primary heat and gas for our secondary heating. The salesman, John, went over all options available, pointing out advantages/disadvantages, etc. The install was scheduled within a week and the 2 technicians who installed everything did excellent work, as well as the electrician. They were professional in every way, courteous, and respectful. They kept us informed of the status at all times and communicated throughout the entire install, including giving us a walkthrough and tutorial on how to use the new equipment. They cleaned up everything and left the area spotless. Overall, I give them my highest rating and would use them again and recommend them to others. I don’t know how Greenwood’s price compares to others, but given the quality of work and professional workmanship, I would say it was well worth it.

Excellent service from start to finish! The team replaced my home gas furnace and did an outstanding job. They arrived on time, worked efficiently, and explained everything clearly. The installation was done professionally, and my new furnace runs smoothly and quietly. The technicians were respectful, knowledgeable, and made sure everything was cleaned up afterward. I'm happy with the whole experience and highly recommend Greenwood Heating and Home Services to anyone needing heating, air, electrical & plumbing services!

Our technician, Salvador, was wonderful to work with. On-time, professional, attention to detail, so kind, and very patient with our barking dog. Love working with Glendale Heating!

Glendale Heating and Air Conditioning is the best. No reason to call anyone else. These guys will take care of you in every way. They are knowledgeable, honest, and efficient. I’ve been a customer for many years and will continue to be one going forward.

Love Glendale Heating! I have been using them for over 20 years. Started back when I had an oil furnace in Arbor Heights. I now have a gas furnace that they installed for me 5 years ago. Great prices, skilled staff, clear communication. Just had my furnace services by Max. He did a fantastic job and very professional. Thanks so much!

Super company and such a nice knowledgeable technician who replaced my thermostat and serviced the furnace. Such a good feeling to be confident in the repairs and a company to trust.👍😁👍
Had them back today for full service and Salvador the technician.was so nice, professional and super attentive to detail I am very impressed. 10-8-2025

The gas furnace cleaning and tuneup services we requested were very well done and well priced. Salvador was right on time, very efficient, and obviously knew what he was doing. We plan t o use them again after a very positive first time experience with this company.

Greg did a great job. He was professional, friendly and informative. He addressed all my issues and I hope to see him again next year!

I have always found Glendale Heating and Air Conditioning to be reliable, efficient, timely, and communicative. What else can you ask for? I’m so glad they are in Burien where I live.
I had a sheet rock ducting issue that needed professional attention, and I got it.

Duncan Hume was my serviceman. He was very professional and friendly to deal with. He took the time to show me how to change the filter and then serviced the furnace for me.
Glendale has always been our go-to for furnace service.

Professional, courteous and for the most part, things went smoothly. I have used Glendale before and I will continue to call upon them for my furnace needs. Thanks again.

Brian and Zeek removed an old oil furnace and replaced it with a beautiful electric furnace with a heat pump. The space was tight but they creatively replaced the furnace. No collateral damage. Amazing!
Greg finished with the install. I am pleased!

Randy is great to work with, very reliable, knowledgeable, friendly, and professional. He did high quality work installing gas furnace at my home, I highly recommend Glendale Heating & Air Conditioning. Thank you Randy!

We had the best team for the install of our mini split and removal of our old oil furnace. Great customer service and friendly team. Special shout out to Tom who is very hard working, detail oriented, knowledgeable and took his time to make sure everything was properly installed. I also appreciate the time he took to make sure everything worked properly and explained everything as he went along.

Tech that came out to was fine but customer service sucks.We spent 13 thousand on a new heating and cooling system the never worked the way it was supposed to and they don’t seem to care. They just want to charge us a thousand to fix it with no guarantee!

I was putting in a new concrete pad under my heat pump so I needed to have a disconnect and reconnect. Glendale was the only quote where they gave me their hourly rate. Everybody else just quoted a price and they were all $1k more given the number of hours it would take. My service tech was Max Ligon and he was also great. Happy to have me peak over his shoulder and answer my questions.

Brian and Zeke were efficient,personable,and great communicators. They were neat in their work areas. I have never before worked with a vendor with such excellent communication,starting with the first sales visit. I will be enjoying my mini- splits.

Past professional relationships are still in tact. Great communication within the company. Fast attention and good service.
I always trust Randy and Glendale Heating.

Everyone at Glendale that I dealt with was responsive, knowledgeable, professional, friendly and willing to take the time to fully answer my questions, thoroughly explain things, and work through the details with me to ensure the system met or exceeded my goals. I got estimates from two other recommended companies and Glendale compared favorably in all aspects. Their price was great, they scheduled the work promptly, and they completed the work on time and on budget. I highly recommend Glendale for HVAC work!

Waaayyyyyyy too expensive. First time they came out cost me over 1k when it was all said and done between them and their referral. Second time was over $200 to bleed air out of a line. Never had to pay anyone more than $150 EVER to come do the things that they’ve done ok my furnace. Unfortunately that guy retired so I’ve been stuck with these jokers. If you plan on hiring them, plan on spending a small fortune for whatever needs done. Service charge alone is $186.

Glendale installed a heat pump and back up gas furnace for me. Very professional shop with competitive price, debra and Sarah that helped me with quotes and scheduling are very prompt as well as knowledgeable. I was debating between two equal quotes and went with Glendale. Happy with my decision one year later. They promptly dispatched someone to troubleshoot first thing in the morning when I emailed them about a possible issue the night before. I would definitely recommend them!
