Our system stopped cooling late Sunday evening during the first major heat wave of the season. Called Brennan's Monday morning and they were able to schedule a repair visit for the same day. Gari Darr came promptly that afternoon and determined that two components had failed ( contactor and capacitor). He noted that the system was getting old (approx 16 years) and that major replacement may be necessary in the near future. I opted to make the immediate repairs and monitor the system operation closely. I appreciate Gari's competent and rational advice and will look to have Brennan's provide a replacement system sometime in the future.
Description of Work: Replaced electrical components on Trane HVAC system. Check system operation.

Rick Michaels from Brennan HVAC is awesome; the most informative, customer service oriented, professional technician that I have ever had the pleasure of dealing with in 20-years of home ownership. We were so pleased that we have decided to switch to Brennan for all of our future HVAC requirements and most definitely will request Rick by name when he is available. Thank you so much!
Description of Work: Performed extensive diagnostics on A/C and furnace, replaced non-op capacitor and got our A/C unit back up and running! Service technician also provided detailed information and pricing options regarding new HVAC systems.

Both services went great but on the second repair their was some confusion with the level of warranty I had on each individual system. I paid the labor fee by phone to resolve the issue and the next day I went and found my warranty information and called. I spoke with the warranty specialist and the service supervisor in charge of my service call and resolved the issue. Both members of the Brennan's team provided great service, were extremely helpful and made the process simple. Overall it looks like the confusion was caused by a third party warranty company but it is nice to know Brennan's stands behind their work and treat customers as a valued asset not a nusiance. I will continue to buy my heating and air products from them as this was the best service experience I have had in a long time.
Description of Work: Two years ago I purchased two air conditioners and furnaces from Brennan's and in the last 2 months both systems had a system malfunction code. On both occasions Brennan's came out the next day to repair the units under my warranty.

We obtained several quotes from Angie's A rated companies for specific Carrier models and Brennan's delivered the best price. The estimator arrived on time and was able to provide a printed proposal instead of a hand written one. The installation crew also arrived when scheduled and they were exceptional. The installation went very smoothly and the technicians were willing to answer all the questions we had and were very knowledgeable. They re-routed some of the copper lines to make the space around the furnace more accessible and did a very nice job with the new sheet metal between the coil and duct work. The re-installation of our Aprilaire humidifier was also nicely done. The outside replacement of the new electrical cut off switch box and condenser unit were also done well. We are pleased enough that we will be switching our HVAC maintenance from the company we used until this spring to Brennan's in the fall.

I've been using Brennan's for over 10 years. In my last house they kept my old HVAC working for years rather than trying to sell me a new system but they did tell me a new system would be far more efficient. In the end I did purchase a new system. My gas and electric bills dropped by half. I should done it earlier. I built a new home and has Brennan's install the entire system including doing all the permit work, installing new duct work and new equipment. I couldn't be happier with the work, the Brennan's crew. They were on time and always professional.
Description of Work: Repairs and then a new system in my old home and all new system and equipment in my custom built home.

We believe there might be a mix-up with the HVAC service provider this customer is reviewing. This review was given to an HVAC company that was at their house on 4/10/2017. We checked our service schedule on 4/10/2017 and verified thru our GPS monitoring system that we were not at this customer's house on this date. Our records do show that we provided this customer with a full heating inspection on 1/27/2017. Our technician found the furnace fully operational; he also cleaned the flame sensor, installed a new air filter and replaced a faulty capacitor in the furnace. To the homeowner, we offer a 100% Satisfaction Guarantee - When a Brennan's Heating & Air Conditioning service technician comes to your home, he is trained to fix the problem right the first time. If you're not happy with the quality of our work, we'll do whatever it takes to make it right. Please feel free to call me at your earliest convenience to discuss this review. Our goal is to provide every customer with an exceptional customer service experience and work proactively with them to prevent equipment failure and to find energy-efficient solutions to protect their family's home comfort and safety for the long-term

The focus was on AC as it was July and we had an inoperable system. We are happy with that. Even though we did not need a new furnace, we knew that our 15-20 year old unit would not last long. Our only requirement was to maintain heating capability because we were by and large happy. Little did we realize that our salesman neglected to highlight that we were giving up a 90% efficient system for an 80% efficient system. You should see my gas bill. Think about how warm this winter has been and my gas usage is double what it was for the same time period last year. I really feel like I was taken advantage of and Bennans laughed all the way to the bank. Our bad for being hyper focused on the AC and not realizing the Brennans pulled the ultimate bait and switch. Buyer beware.

I would like to start by thanking this customer for taking their time to tell us why our service failed to meet their expectations. We value your business! It is only through feedback such as yours that we are able to maintain and indeed, where necessary, improve upon the services that we provide our valued customers. As you know, we immediately reached out to you to address your concerns regarding the efficiency of the new gas furnace. And, we appreciate you meeting us at your house for a site visit. Hopefully we have assured you that we DID NOT decrease the efficiency of your gas furnace. Your existing gas furnace was an 80% efficient furnace! In no way did our estimator try to take advantage of you nor did he neglect to highlight the equipment being offered to you. We believe in full transparency and our goal is to provide our customers with as much information available during the sales process. The proposal we provided you clearly itemized the manufacture, the make and model of the furnace; to include the efficiency level. We feel our sales estimator went above and beyond the call of duty to provide you with exceptional customer service; to include, driving to his house, picking up and delivering a portable air conditioning unit to your house, so you and your family could have some relief from the heat until your new HVAC system was installed.

I'm real happy with them. They're my people. Three guys came out for the install. They were prompt, professional. I keep using the company because they seem to know what they are doing, they're very responsive and a good product.

They are a big company in this area. They come out twice a year, unless I have problems. I have an annual maintenance contract. It cost me $129 for the filters, but the call itself was free, but not really free because, the contract is $300. They're responsive. If I don't call them for the spring or fall check-up, they'll call me. They are very good about that. The check-up is thorough, they aren't in and out in 15 minutes. It takes them about an hour or so. They check everything, and we have two systems upstairs and downstairs. We have two furnaces, and two air conditioning units. They are professional and punctual.
Description of Work: Brennan's Heating & Air Conditioning Incorporated did a fall service. They did a furnace check-up. They installed a couple of filters.

I have a contract with them so every 6 months. I have a service contract with them so it doesn't cost anything because I have a contract. It's an A for the contract. I just renewed the contract this week. We've never had any major work done. They installed the system years ago and it's still working. It's just maintenance. They've never had to do anything really because it was a good product to begin with. They are excellent. They are very professional. They don't make any mess. They put things on their feet. They are very good. I am very happy.
