They weren't easy to talk to and were abrupt and short with me. I was disappointed with the service I received from them. It took them two and a half months total to get it finally figured out and all that needed replaced was a thermal coupling. I do not recommend this company.
Description of Work: They checked the gas fireplace. It took three different techs to come out before they found the problem.

We called several from the A list and all responded. The only difference was $500.00 in price. The second on our list told us that Brennan would be about $500 less but didn't know why. This was Genessee and he was terrific. He even showed us that our whole house air cleaner filter was in backwards and changed it. If not for price, he was our second choice.
Description of Work: They went above and beyond making sure that the older components of the hvac system could communicate with the newly installed unit. They were punctual and friendly. We were dreading this experience, but they made it painless. Would definitely recommend.

I initially got my heater from them, and they knew what they were doing with that brand. I think the technician did a pretty good job and seemed to be very efficient. He also helped a lot with the filter, and I was happy with the service.

We had our gas fireplaces serviced two years ago, and when they did it, they actually checked the insides and cleaned out the inside, and checked the connections with the pipes, but Brennan didn't do that, and when I asked they said that they don't normally do that. In making the comparison I wasn't too satisfied. But the fireplace works, there isn't anything wrong with it. They also charged less than the last people that came.

The company we bought the furnace from said they could not make it out for over a week. When I called Brennan's a pleasant person answered the phone and scheduled the following day. I took time off work to meet him there - he was early! He gave me an estimate (the amount I expected) had it done and was gone within a half hour. What a pleasant experience!

The salesperson Todd was on time, spent time counting air vents and checking out my existing system; explained the different AC and Heat Pump units available, and provided me with estimates before he left. It took about an hour. Todd was professional, to the point, pleasant, and gave me just enough detail. The day of the installation: everyone arrived on time. The AC people, the electrician and the vent cleaners all came and went as needed. They were all professional and tidy. The only problem was at the end of the day when the two remaining technicians were finishing up, they realized that the heat didn't work and thought there may have been something wrong with the wiring. When they couldn't figure out the problem, they placed phone calls and said that another tech (an electrician) was going to come back over and check it out. He said that the tech was "up at the corner at the gas station and would be here in a few minutes" but it was more like a half hour. I don't know why he claimed it'd only be a few minutes; if he'd just said it'd take a while, that would have been ok with me. Anyhow, the electrician came and fixed whatever the problem was and they all left by 6 pm. I think that usually they would have been done around 4 or 5 pm. It wasn't really a big deal, except for when the AC man told me the electrician would be over in a few minutes but that didn't happen. Everything works as expected. Everytime before and after the installation that I had questions, I called Todd the salesman and he was available to answer my call or called me back right away.
Description of Work: Installed Lennox AC unit; added air return in 2nd floor loft; increased size of air supply to 2nd floor loft

The technician called to say he was on his way, arrived 15-30 minutes after his call, and completed his work in a timely fashion. He told me that he recommended a new furnace due to the age and amount of rust on my heat exchangers, but said that I wasn't in immediate need of a new furnace since he found no cracks or leaks.

My current furnace broke. I checked Angie's List for companies with good grades. I found Brennans and called them. A representative came out the next day and gave me an estimate. I had done research on the internet. I accepted the quote. They said since I was without a furnace they would even install it that same night. I declined and they came out the next morning. It only took 2 hours. They cleaned everything up afterwards and did a good job. I used the $100 off coupon from Angie's!

Originally we had called Brennan to perform an annual service and check-up on an older Lennox gas furnace. During the servicing, it was discovered that the heat exchangers were cracked and needed replacement. We decided to replace the furnace instead of the heat exchangers. Brennan was able to come out and replace the furnace within a week. They stuck with their estimate and even deducted the servicing costs of the old furnace from the previous visit.

The technician was extremely professional, courteous and helpful. He spent over 2 hours at our house running up and down stairs, inside and out. He also commented on the appearance of the inside of the duct work and suggested a company that comes out and cleans them.
Description of Work: Performed maintenance on two gas furnaces and one A/C system. Hooked up an exterior fan system that was not hooked up properly on one of the furnaces at the time of install. Noted that a dryer duct in the attic (where one of the furnaces and a/c is) had become disconnected and was venting into the attic, helped fix this.

They were really nice and showed up on time. They did a pretty good job and let us know what we had to do to get it done correctly. They were knowledgeable in what they did. **** Update 2/8/10 I never received my energy efficiency discount. I have called them and they have said they would send it through. Since they have not provided this to date, I will not use them again. I plan on contacting the attorney general as well. I am not satisfied with their response to my request or the hot water heater they installed.

First, I have to praise this company for replacing my old furnace in a timely manner, but I do have a few gripes. Workers damaged wood trim during the installation and left several greasy hand prints on walls. Most recently (6/08), I called the company and left several messages for someone to call back. All of my calls went unreturned. This was an urgent matter, as I need to inquire about a smokey smell eminating from the furnace while running. Smoke detectors were going off constantly and the pipes were very hot to the touch. When I finally got a hold of someone during regular business hours, I informed the woman who answered that my calls, up to that point, had not been returned. Her smug reply? "I'll transfer you to the service desk." No "I'm sorry for the inconvenience", Nothing. Very unprofessional. Unfortunately, the guy answering at the service desk wasn't an improvement. He assured me he would be sending a message to the scheduling desk to have someone contact me for a service call. That call never came. After spending $4k with this company, I expected more in the way of customer service. I won't be using or recommending Brennan in the future.
