They are very dependable. The guys were in and did their work quickly. They cleaned up their mess and took all the garbage with them. They perform very consistently and are easy to work with. They sent 2 people out to install the new furnace.

Everything went well. Had good communication with the service providers. The tech who had my account was Junior, he was very helpful and explained everything to me well. I was always able to get a hold of him to get my questions answered.

Brennan identified that the ignitor needed to be replaced upon inspection of the air gap. Getting it done preemptively probably saved us an emergency call this winter.

They did a fine job. That gave me an estimate for additional work, but I went with another company that my home warranty company recommended.

My wife and I attended the home show with the intent of having air conditioning installed in our home. We talked to a rep. and he said he would send a tech. to give us an estimate. A couple of days Brennan called and asked when we would like someone to come to our house and give us an estimate, I told him that I had already scheduled my furnace for an inspection and that person probably could give me an estimate . This would save them some money not having to send 2 tech's.
 I stated previously the tech. inspected the furnace ( 10 minutes ) and informed me that I would need a new furnace or he could replace the cracked heat exchanger . It just so happened they had a special on new furnaces and I would really benefit by having
him install it. The technician was extremely hard to understand , my wife and I had a difficult time knowing exactly what he was saying...his English was not good at all. He seemed insulted when I told him I only wanted to repair the furnace and not replace it.
He wanted $100.00 for the visit and I asked him if I could just include that amount when he returned to repair the heat exchanger,
he wasn't sure he wanted to do that but I said it made sense to only write one check when he returned.
He returned 5 days later and repaired the heat exchanger . I had to go out to his van to have him show me the cracks in the heat 
exchanger . I'm really surprised that he did not think it was important to show me the damaged heat exchanger. I paid him $1200.00 which included the money for the previous visit. About a week later I got another bill in the mail from Brennan saying that I owed $100.00 for the first call . I called their office and explained the situation and the woman apologized.
Over the years I have paid Brennan thousands of dollars for a lot of work they did but they will not receive any more of my business. I read another review for them on Angie's list and it sounds just like mine.

Responding pretty quick. Was on time for appointment but price is more than what I expected. I thought $1899 for including labor but permit and other fee is involved about $2800. Still furnace is working ok. I used them before, good reputation. Maybe next time. Thanks.

I purchased a coupon for these services through Angie's list.



Pro's: punctual, completed work in a timely fashion



Con's: perfunctory demeanor of service professional, did not replace filter



I appreciated the opportunity to try Brennan through this coupon, and while I wouldn't say it was a bad experience, nor would I say it was a good one.



I expected that replacement of the filter was a part of this service, but the technician did not have any filters of the correct size for my furnace. The only offer he then made was to install it if I went out and bought one, but he departed while I was still trying to track one down.



Admittedly, I cannot remember if I ever confirmed with Brennan that filter replacement was a guaranteed part of this coupon - but even if it was not, this isn't the kind of in-person customer service that leaves me keen to contract them again.

It took them a week to contact me. When I talked to them I told the receptionists that my venting needs to be replaced also. They said they would call between 1-4, he didn't call till 5 and didn't show up till after 5. When I showed him the vents he said he didn't know anything about the vents and he couldn't do them right now. The receptionists had left the company. I showed him the duct tape that I had put on my vents for a temporary fix (recommended by Lowes). He told me it was flammable and unsafe. He told me that I would have to make another appointment to get everything done. I did and he came out a week later. He then replaced the vents and looked at the furnace and said that I had a crack in my motor and it needed to be replaced or the whole furnace replaced. I wanted to think about what I wanted to do. This was on Thursday and I realized my furnace wasn't working and it was getting colder. I turned the breaker on and the blower started but the air was still cold. Monday I called them and asked why, they said to turn the breaker on and I told them I already did that. The guy then said I didn't have heat because I refused to buy the motor. I told him I didn't refuse, I just wanted to think about it. I contacted another company who came out and told me that my furnace had been completely turned off and that there was no crack in my motor. They cleaned it and it has been working fine.
Response from Brennan Heating & Air Conditioning
"First off thank you for originally purchasing the Angie's List big deal for cleaning your furnace. We were called out to perform a general maintenance on your existing furnace. On the first arrival we pointed out that your venting connector was rusted out and had been fixed with duct tape which is against code. Once we replaced that we did perform the GM. We found that your inducer motor had more than 4 large cracks, 1 that went from front to back and is very easy to see. When an inducer motor cracks it does become a safety hazard to everyone in the house. We have a company policy that we will not leave a furnace running that is not safe to operate. This is for the homeowners safety as well as liability for our company. We offered to replace it. If another company doesn't have a problem running an unsafe furnace that is between them and you, it will not happen at Brennan Heating. When we are called out to a house it is our job to perform the service but also our responsibility to point out any potential problems and to not leave an potential dangerous furnace running. I hope you understand. Thanks."

Brennan Heating did a great and prompt job switching my house from Oil to Natural Gas, including removing the old nasty oil furnace, installing a new high efficiency gas furnace, cleaning the ducts, installing some new ducts, and installing a new water heater.  Given that the old furnace was broken I had no heat, and they took that into account and quickly got the job done.
A special shout out to the estimator Todd, who called my home warranty insurance provider a number of times to provide information to help me get a claim on the failure of my old oil furnace.  Thanks Todd!

Not much cooperation on location of furnace, they had to come back for repairs multiple times. They just didn't seem to care.
Response from Brennan Heating & Air Conditioning
"I apologize everything did not go as smooth as it could have. We install a lot of Lennox furnaces but on occasion we might to come back to replace a part. In our opinion they are the best furnaces made but even a Lennox will have a problem from time to time. We do have a large service department and pride ourselves on being the most responsive company in our industry, our desire is make every customer extremely satisfied. I am confused on the furnace location comment. This house is a rental house of yours and price was your number 1 concern according to you. We can always move a furnace to a different location but that does take more time and materials which in turn will increase your purchase price like we discussed. If you would like a price on relocating your equipment please reach out to us, thank you."

The technician was punctual and did the work fast. He was explaining some potential issues with my furnace, changed the filters, cleaned some dust that escaped, and then left.

Brennan is a superior service provider.  We have used them in the past to clean and upkeep our furnace.  They have never tried to up-sell or push product we did not need.  Will definitely use Brennan again.

I emailed them the same day and set up the consultation for the following week. I upgraded the electrical filter and had them clean out my vents in addition to the installation. The service was perfect. They were very informative and answered all my questions. They showed me how to use and clean the filters. I dealt with five technicians and they were all very professional. I have already recommended them to coworkers.

On February 8th, I purchased a Deal for $99 gas furnace service which included a filter and installed carbon monoxide tester. I called within a few days of purchase to set up an appointment. No one could come out until February 24th. I was to be the first appointment - and was told the arrival would be 8 AM. At 8:15 I called to see if someone was coming or if I had the wrong date. I was told that the technician was on his way but stuck in traffic. At 9:10 when the technician still hadn't arrived, I called the company back and was told the technician had never intended to be to my place at 8 AM. I guess the first person I spoke with used "stuck in traffic" as an often used excuse rather than the truth. I would think that most folks who knew they were the first appointment and appointments begin at 8 - would assume the worker would arrive at 8. Maybe the technician could have made a call and given me an ETA. I cancelled my appointment and refused to reschedule because of Brennan's appointment scheduling practices, lack of communication with me, and their treatment of customers - as if I'm doing them a service by using their company. Very poor customer relations on the part of Brennan's telephone and scheduling staff. As I was cancelling the deal with Angie's list at 9:15 AM, the Brennan truck drove past my house. I have a 2 person office that is supposed to open at 8AM in the morning. My office manager was ill today. So because of this lack of communication, on Brennan's part, my office didn't open until 10 AM - 2 hours late and my furnace wasn't serviced. I got the shaft rather than a deal on this transaction.
Response from Brennan Heating & Air Conditioning
"I am sorry for the confusion. We have been in business for decades and have never scheduled service calls in a 15 minute window. We have always given a 2 hour window and are very clear when setting appointments. Because of traffic and not knowing how long a service call will take we are forced to have these windows. I am sorry for the confusion and wish we could have a second chance but you did receive all of your money back. I was happy to see that we did arrive within our 2 hour window but I am sorry we were not able to perform the service you had pre-purchased. We always strive to have the best customer service in the business and will continue to work in that direction. Thanks."

I have not hired the job out yet, I really wanted to go with Brennan but there quote was $3000 higher than my lowest quote, I asked them to discount the job by $1000 and they said no, I am willing to pay more to have them do the job, I just don't see myself paying $3,000 more.

I felt that the person I talked to about setting up a service call was rude and condescending to me and I will not use their service ever again.
Response from Brennan Heating & Air Conditioning
"I apologize your experience with Brennan Heating was not what you hoped it would be. We have a large service department and work hard to satisfy all of our customers and potential customers. In our industry when it gets cold we obviously have a spike in phone calls and try our best to get to everyone. When the spike hits we have a policy to always take care of our customers first, meaning the people we have installed equipment for. We feel very strong about doing this because they have trusted us with installing their equipment and with that comes our desire to always take care of them even if that means evenings and weekends. I apologize that the company you hired to install your equipment wasn't there for you and I wish we had space on the day that you called. I hope you understand our position. We are always working with our staff on customer service and trying to satisfy everyone who calls but at some points during the year we are just overloaded and cannot get to everyone. Thanks you for reading my response."
