Reviews of local pros in Seattle, Washington

The Brennan Heating and AC team was composed of 4 workers: Installer, HVAC technician, electrician, and a helper. They took out the 30 years old electric air handler and heat pump and installed a new Lennox system. One challenge they had was to connect the existing duct work to the new system. They struggled but persevered. I have to commend the installer for how he handled the frustrating task of connecting the unit. The electrician ensured we were up to code by installing an outlet accessible to the heat pump. The technician informed me that the hole through the foundation for the pipes from the heat pump to the air handler was not large enough to accommodate foam insulation. But it wasn’t a significant heat loss. The helper was attentive to the other’s needs. Standing by and stepping in to assist when needed. They worked as a coordinated team which was satisfying to watch. They cleaned up the debris and scraps and took the old dirty system away. Scheduled in April is an air duct cleaning. The system is quiet and heating well. The COSTCO cash card coming in a couple weeks is a plus.

It was easy to schedule our maintenance service, and communication was great with the office and with the technician. Our technician (GM) arrived when she said she would, was thorough, cheerful, and efficient. She serviced 2 systems that we have - a ductless heat pump and an all-house furnace/heat pump sy.stem. She had all the right tools and equipment, and was focused on getting the work done efficiently and correctly. I would recommend her and Brennan.

IBS Provided excellent service and was very helpful. He was professional, a great job and was good to work with. I would use Brennan and him again

Had a mini split installed on 4/1. Installers hands down great workers and people! Wife even made them lunch. They were a pleasure and professional and clean.

After not getting an invoice for a month I followed up with the company to get a status. I had this project financed and the bank got their invoice and submitted payment.

During my call with the office I let them know that I still didn’t have the mechanical permit and the inspection had yet to be completed. Additionally since working with the team on their proposal and the contract I have been asking to get a service contract set up to stay in compliance with the warranty. Still nothing.

Yesterday I leaned that the finance short paid them by $90. I was called and told I needed to pay now and what CC would I like to use.

I said oh thanks for calling could you please tell me the status for the mechanical permit/inspection as no permit was sent with the package and also let me know about service and a service contract.

No information was made. An email was sent because I do not want to pay the $90 until the project is completed and closed out with the final inspection.

Updates will be done as this project gets completed and the company gets their final $90. Project finished and closed out I will happily pay.

Overall other than installation not a good experience and will be reaching out to Costco!

Brennan Heating has been fantastic for their professional installation and maintenance for the past two years! We went through Costco and we have not had any issues. From installation through service it has been a wonderful experience and we expect that our gas furnace and 3 ton air unit(both Lennox) will stand the test of time. Each employee from sales, service, and administrative assistants contacted by phone have been professional, friendly, and adept at being helpful in their respective fields of expertise. Costco and Brennan Heating are committed to providing the best to each of families that put our trust and safety in their spheres of influence. Thank you both! Sincerely, James.

Got our HVAC system via Costco 2 months back. Had a bunch of issues to deal with till now.
1. Air ducts was not sealed properly, so hot air was leaking out. Put some duck tape myself and asked them to add a missing cap on the newly added pvc pipe.
2. There was a constant buzzing sound from HVAV unit and it took 2 technicians visit to resolve it. 1st time it was miss diagnosed. There seems to be lack of training.
3. After the sound issue was fixed (#2), they missed to configure the thermostat. So now it’s giving some system warning which looks like some setting is not set properly. So waiting for another visit from them.

Hopefully all issues get resolved soon.

This is our second home that we have had Brennan heating and cooling do installation of a furnace and cooling system and hot water heater. The salesman was very knowledgeable and helpful in making our decision. The install team was very neat and clean, explained the new system workings very well.

We had a great experience with Brennan installing our new mini-split, ductless heat-pump/AC system. Went through Costco so we also got 10 percent back in the form a cash card. Paul, our sales person came out and recommended a 2.5 ton system for our log cabin - he didn't over sell us on a bigger system like 2 other HVAC companies tried to do with their bids. Also, the Brennan bid came in way less than the other two (do your diligence and get 2-3 bids is what my Dad taught me). The crew that came out to install was also top-notch and super friendly, I highly recommend Brennan for their service, professionalism, value and quality of equipment they sell.

Brad from Brennan was great. He went through our old furnace and said it is in good shape. He explained what possibly caused it to stop and restart in a few hours and that there is 'No Need to Replace' it. Best service on the planet!

Ibrahima did a great job servicing our fur as. He was on-time and ready to go. Ibrahima was very knowledgeable, helpful, and above all very respectful and friendly! I specially appreciate his workmanship and dedication! Thanks Ibrahima!

Kind regards,
Ahmad

We chose Brennan Heating through Costco and paid several thousand dollars more specifically for the higher level of customer service we were promised, but the experience has been the opposite. The installation was left incomplete, multiple technicians failed to fix issues leaving us with no heat and the communication throughout the process was extremely poor. The salesperson who introduced himself as our project manager repeatedly promised phone calls he never made, and at one point even told me he was “equally frustrated,” which was incredibly upsetting given that he was supposed to be managing our project—not commiserating. We also dealt with miscommunication about a scheduled duct test and repeated scheduling issues that required family members to drop everything to let technicians in. After paying over $22,000, the lack of professionalism, accountability, and follow-through has been extremely disappointing and far below what Costco customers are led to expect.

After repeated attempts to get someone to contact me to resolve our issues we felt we need to share our experience in an effort to prevent others from dealing with this. I will be sharing all details with Costco as well.

Brennan heating install my Heat pump and furniture.from Costco. Dakota service rep came and service my unit. At that to time we discussed my concerns about the lack of flow to a particular section of my house. He went underneath my house and said that the duct needs to reroute . He said that he would work up a quote and get back to me. Several weeks goes by and I haven't heard from Dakota so I called Brennan and they told me they have to speak with Dakota I never received a call. Several months has passed. I called Brennan and they again told me they would call me back with a quote. Twice they have said they would call me back and never followed through. Brennan Im sure Costco wouldn't be happy with the way you are treating their customers. Don't worry about contacting me I will take my business somewhere else.

READ BEFORE DOING BUSINESS WITH BRENNAN!

This is a review that started 11 years ago. I was in need of a more efficient heating system. Costco had a Brennan rep at the exit. I spoke with them and I ended up with a Lennox mini split installed for $6400. Everything was great. Fast forward 11 years, the outside unit failed at the coldest time of the year. I called Brennan and they sent out a tech. I was told the unit was dead and parts were no longer available. I was quoted $11400 for a lower quality system! Even with cost increases over the years, double seemed excessive.

I had another tech from another company out. He told me $300 to install a new control board but it was possible there was a short that would fry the new board instantly. With further inspection, that tech found that the needed 4-wire bundle from the outside unit to the head unit was actually a 3-wire with no actual ground wire. Instead an 8 inch wire with a striped end on both ends that used the metal interior of the conduit as a jumper was used as the ground wire (See photo). The new tech told me this is most likely what caused the failure and was an improper installation. And if the permit inspector had known that's what was done, they would have never sign-off on the installation.

I found a more affordable option and finally have heat again. I attempted multiple times to contact Brennan to let them known about what was found. I finally spoke with a supervisor after leaving several unreturned voice mails. I told him the situation and he basically said, it passed inspection and they wouldn't do anything about it. I told him I still have the old unit and wire to show them the problem. He said it's been too long and again that it passed inspection. I asked him if they would at least haul away the old unit because refrigerant requires a specific disposal process. The supervisor agreed to email me after he spoke with the owner. It's been months and I have received no emails or phone calls.

Be warned, Brennan takes short cuts and does improper (if not illegal) installations. If you have any equipment installations done by them, speak directly to the permit inspector before they sign-off on the permit. Don't let their short cuts cost you thousands later on.

On one of the coldest days of the year our furnace malfunctioned. Brennan responded right away and got the furnace fixed same day. The technician, Ibs, was punctual, courteous, clear in explaining the problem and fixed the problem. Thanks for the great work.

I needed a furnace check-up/ tune up.
The technician Daniel showed up on time with an awesome attitude.
Very considerate about our surroundings.
And went right to work.
He found some things that needed attention explained to me what they were showed me a part that needed replaced gave me the cost of the part and asked me if I wanted it replaced.
Daniel did all the work cleaned up and was done in no time..
He let me know my furnace was in good shape.
Very professional .
I would use Brennan again and again.

I needed to have my hot water tank serviced so I contacted Greenwood Heating and Home Services because they do a yearly service on my gas furnace. Marcus came out and did an excellent job. The overflow tank had failed and Marcus replaced it. He was so kind and knowledgeable and did a great job. Also, when I call their office to schedule appointments or ask questions someone always answers the phone, is pleasant and helpful. I highly recommend this company.

Great work by this company assessing the upgrades we needed after our furnace went out 2 yrs ago. We upgraded to a heat pump, and they did an excellent job installing the unit. We had an annual inspection and maintenance done this year; Branden did a great job…he was very thorough and explained the whole process of what he did/very knowledgeable about the system. I highly recommend
Greenwood Heating.

Excellent HVAC maintenance service. The technician performed a thorough system inspection, cleaned and checked all key components, verified airflow and performance, and made sure everything was operating efficiently. They explained the condition of the system clearly and pointed out any preventive recommendations without being pushy. The work was clean, professional, and detail-oriented. Very reliable service — highly recommended for ongoing heating and home system maintenance.

The issue with my furnace is not straightforward. The Heating Technician Paul, was patient, courteous, empathetic. After listening to my description of the Furnace’s issues, he examined it, explained possible causes and then spoke with the manufacturer to glean more insights regarding the most logical way forward. He explained these to me and provided me with a recommendation for a plan of action. I agreed that it was the best way forward. The furnace is not yet fixed but i was very pleased with the level of service from the personal to the professional that Paul provided.

I was referred to Greenwood heating from my son who is a fireman, and I was not disappointed with their service.
David arrived on time, he was very personable, very knowledgeable and very helpful answering all my questions. I’m a senior citizen and I found David very honest and not high pressure sales as I had anticipated. After servicing my system, he explained everything to me, he even assisted me changing my filter because this was a new system to me. He showed me “inside the box” and made me feel very comfortable.
My system is functioning more efficiently now, and he gave me some tips to ensure that. I look forward to his return next year and making sure my system is still continuing to function properly and efficiently.
I highly recommend Greenwood heating and I already have to my neighbors and friends.

Wow Thank you Greenwood, shout out to Lake Stevens ( The employee, not the town ). I never thought a maintenance visit would be so fun! Lake was professional, super enthusiastic , and I can tell he really loves what he does :) He taught my partner and I everything we needed to know about our furnace. Might I say he was very thorough, and made sure we knew what was going on with the pictures he showed us, and explained all in detail. We have never had someone take the time or care enough to do that. Not only do we have a new maintenance guy now with Greenwood, but a new friend :) thank you Lake, and everything you did for us. 10/10
