CM Heating for install AC

I called to explore how expensive it would be to upgrade our heating and maybe add AC. I never expected that we'd have a brand-new HVAC system running smoothly the very next day. CM delivered a lightning-fast, high-quality install with top-notch customer service. The process was completely painless, even despite…
The workers were professional, friendly, and competent.
Great service! Professional, prompt, good communication.
Great guy overall. Extreme attention to detail. I wish all customer service representatives were like him.
CM installed my heat pump a few years ago and have taken great care of me ever since. Had an emergency and you can call day or night and they send someone right out. Love this company and the crew is always so friendly and professional!
You will not find a more professional HVAC/Plumbing/Electrical company anywhere in the Seattle area! These technicians are very highly trained and the services they provide are consistently excellent. We've used them for years. My company has also utilized their services for many years. They are not the least…
Joe was super knowledgeable, explained what I needed, went over installation and the process in detail.
Amber Maddalena started the process walking through CM’s warranty on mini-split installation in our condo. They ended up being the lowest price and their 12 year parts and labor warranty was the best of any company we quoted (we got 4 quotes). Amber worked with me through the process (we were the first mini-split…
CM Heating are pros at what they do! They do an excellent job scoping the work (needed to add a single ductless head to my existing AC system), planning out two viable scenarios in case one install plan didn’t go as planned. We ended up with plan b. Amazing communications, consulting experience and install…
Quick friendly and very accomodating, I would highly recomend them to anyone needing heating or cooling work done.
Very Good Company over All.
An absolute delight!! Thank you!!
Update: it’s 2026 and I’m very happy with the new water heater I had CM Heating install. I’m happy with the service, the quality of the water heater, the warranty, and the pricing. Update: it’s 2025 and I’m still happy with my service. Brandon was an excellent tech and brought me up to speed on the status of my…
On time, works perfectly
Davis did a great job! Was expecting possibly a high pressure sale approach but it wasn’t. Presented the options and price and answered all our questions. Haven’t decided for sure but thought the quote to install a mini split was reasonable.
Very prompt, efficient and knowledgeable in all aspects of our service call.
5 stars Mack is the man!! Got my AC working perfectly.
Awesome service! Friendly, direct, and very knowledgeable.
I am so happy after using CM Heating to replace our furnace & A/C! From the beginning they have exceeded my expectations. Chester during the initial visit & estimate was friendly, thorough, paid attention to our needs & concerns, and answered all of our questions. After scheduling the install with a quick…
Entire process from start to finish was professional, friendly, low pressure and technically sound. Installation team arrived on time and were finished by mid afternoon. They explained differences between my old gas system operation and the new heat pump system. My biggest worry switching to heat pump was that air…
Spencer is not much of a carpenter 😉 !!... but he is a hell of a lead tech. He was prompt, polite , communicative, and patient. He treated his co - workers with respect and humor. He treated our home as if it were his. He treated us with respect and explained everything to us . He's a hard worker and very…
Spencer and Remis did a fabulous job installing our heat pump and fireplace. They're courteous, efficient and knowledgeable.
They are the best and so professional and thorough. They installed a new system and from the first call CM heating has been 100% the best
Amber did a great job walking us through all of our options for A/C in our home. She took the time to give us several bids covering all our possible choices. She was very personable, patient and informative.
Jay was incredibly knowledgeable and helpful. He did a great job of explaining my options without being overly pushy or trying to upsell me. He listened to what we were looking for and provided a bid that met my needs. He took the time to explain our system and answer all our questions. He was also very friendly…
Chester was very polite and professional, explained the process, always checked to see if we had any questions, no hard sell tactics at all which we appreciate very much.
Always great customer service and the Techs are professional, knowledgeable and friendly. I did not have AC installed, just WAYYYY to expensive now days compared to 3 years ago. DOUBLED. But Tech was honest with me and I was strait with them. No harm no fowl. No push or pressure. Thanks for the service :)
Excellent job!
Spencer arrived timely, was friendly and didn't waste any time getting the old furnace out and the new heat pump installed. He explained the process and where they would be working so I knew what to expect. He answered all my questions during the install and gave me a complete tour of my system and how it works. I…

Fabulous! They showed up on time, were professional and made sure everything functioned properly. They worked hard to install a fabulous new unit for us.
I sought three bids on installation of a heat pump and tankless water heater. The other two were from bigger name companies. CM is what we're going with. Their presentation (Well done Tyler) was clearest and most informative, their product line up features the Mitsubishi HP, which is what I wanted, and their array…
Chris, Rodrigo and Anthony did a great job! Really appreciated their flexibility when the install was modified because of permit issues. They explained each step to me and incuded .e in the process! Well done!
Cheryl and I invited CM Heating to our home for a consultation on a new Hvac system, Trevor Bohm came and gave us a consultation, he showed us our options, and he was upfront with costs. We immediately were informed that we were qualified for financing. The ladies answering our calls, have been very nice,…
Awesome experience! Highly recommend. Amy contacted me & let me know who/when someone would be at my premises. Engineer (Lyle) came out & explained furnace & AC placement. Joe gave me an estimate immediately & pricing is competitive. Friendly/informed/professional. Once I made up my mind (old furnace broken)…
Jacob was quick. He clearly explained everything before he started and then reviewed everything with me upon completion.
We really appreciate the techs at CM heating. Zachary did an excellent job and took the time to teach me a few things with a kind way that left us in no doubt that CM gets all my business. We pay the yearly service fee and it finally paid off. Thank you all at CM for your kind attention.
He did great job to install the new heat pump unit.
Justin was excellent! He and his assistant were on time, polite, and communicative about everything during the whole installation process. When the initial install had problems due to a mistake in the proposal, Justin returned and went above and beyond to repair the problem and even built us a new furnace to make…
Josh installed wiring for a mini-split system and explained what the best option was for routing wiring unobtrusively
Extremely professional service, Dane was very helpful and provided all the answers to my questions. Super informative. I like that I never felt pressured and gave me a very competitive quote.
Trust me when I say that this is the company you want to have work on your home. We needed our electrical panels, HVAC equipment and plumbing piping replaced and they knocked it out of the park for a great price. No change orders for ticky-tacky things, amazing communication, and took care of all the permitting /…
Promote response and thorough research.
Very informative about what services would be the best option for my home. Getting everything installed next day! Entire process was seamless.
Emmanuel did a great job fixing our heat pump! We appreciated how fast he was able to come out and stayed to make sure everything was working fine. Thank you so much for being so diligent!

Hakan showed up on time and was very professional and friendly. He didn't find any problems with our system but did find and remove a frog that was electrocuted in the heat pump(poor Kermit). Cand M Heating gets a 10
Spencer was the lead install coordinator and made every effort to answer my questions, communicate and check with me first on any major decisions / steps.

We appreciate his tenacity and sincere interest in our satisfaction. CM Heating, you need to appreciate…

Melvin is great, very efficient, pleasant and professional! Melvin's team installed 4 AC units in our house (3/4 pictured here because my husband is in a meeting with the AC in his office).We have loved all our CM Heating experiences so far. Thank you!

Great company to work with, always! 5/6/21…
Very professional and just a nice guy.
Timely scheduled appointment when my HVAC hit end of life Monday afternoon. Great estimate visit Tuesday morning. ANSWERED ALL MY QUESTIONS and had information for me that helped me decide on correct system for my house and how I use it. NOT high pressure sales visit. Professional advice to help me decide how to proceed. This fellow knows his stuff!
As Always - Great service and quality recommendations. Evan was fantastic! On time, no issues with billing or services. Installing a new furnace to fix huge errors made by previous owners and expediting as well... First Class all around.
We just had central AC and an air scrubber installed in our new home by CM Heating. Chris and Luke did an amazing job from start to finish, as did the electrician, but I don't recall his name. They texted and called when they were on the way, and were prompt, efficient, professional, knowledgeable, and courteous!…
