out of 5 starsMy Review by davidf135399183 on 2/10/2014 via Citysearch
I just purchased a new mini split unit from Brennan and they were great! The installers were knowledgable and skilled. Very kind and even took time to talk with my curious 2 year old little boy. (He still talks about the heat pump guys)…
These guys are the best! by Tina L on 11/18/2011 via Insider Pages
I had to have a furnace, our furnace had completely failed and was pumping CO2 through our house. I shopped around, did all my due-dilligence on high-efficiency furnaces and got three bids that varied in price by $2000. Brennan offered…
Trust worthy by Rsteketee on 10/31/2011 via Citysearch
I left my home and asked them to complete their work before I come back and believe me they did their job perfectly and on time
satisfied by Tara M on 2/23/2011 via Insider Pages
This company at least takes the time to right any wrongs that may have occurred, and the techs have always been knowledgeable and curteous.\r \r Will use again,thnx brennan!
Skeeter by Sscout S on 2/20/2011 via Insider Pages
Oh these guys are chumps! Dont waste your time with them. Techs are not trained and the service personnel could care less. Waited weeks for parts without any callbacks. Spend your time and money with someone else.

Questionable Advertising by capnk31530 on 6/9/2010 via Citysearch
While Brennan's service is adequate, I think we need to hold businesses accountable for the people they pay to endorse them. I hear the radio ad for this business on KIRO today, during host Dori Monson's show. Monson's blog headline…
Happy With Hardware and Installation, but... by DrR on 11/19/2009 via Citysearch
Ben in sales was great. No pressure and pragmatic. They also threw in a duct cleaning. Brennan was able to install the very next day. Because of that we ended up getting a high level furnace from Brennan that works great. Install…
Conflicted by Jen S on 10/12/2009 via Citysearch
The install crew left a freezer unplugged. This went unnoticed for four days. Thank goodness my 1/4 steer was not damaged, but everything else has frost on it and will suffer in terms of flavor. This is a nuisance and should have been made…
Happy Homeowner!!!!! by J.A. P on 5/9/2009 via Insider Pages
We have an older Colman furnace in our home that failed recently. Not knowing who to call for service, we asked a few friends of ours and got Brennans name as the company to call. I called and got same day service! Being that our furnace…
Brennan Went Above and Beyond by dhhumphries on 2/9/2009 via Citysearch
My wife and I just had our old oil furnaces replaced with gas furnaces.\r We were thinking of having the work done by Brennan because I?d read and heard good things about your company from a variety of sources. An appraiser (Rodney) came…

just wanted to say thanks for the professional service. Your technician did a good job of helping us choose the right products for our needs - the variable speed furnace for our home, and the two-stage furnace for the rental, not to…

Wanna go for a ride? by forrest1 on 10/19/2008 via Citysearch
I called Brennan to have my furnace maintained. Tech said my furnace was broken(although it worked fine).. said he could fix it next week... or install a new furnace tomorrow! Explained how much he wasn't trying to sell me something,,.…
Mixed feelings by Michael F on 9/7/2008 via Insider Pages
Brennan installed central air conditioning in our home a couple of years ago. They system itself functions fine - so no complaints there. What I didn't really appreciate is that they left things looking very unfinished. Black-colored…
