Outstanding service as always. We've used Brennan's in the past. Told them we were OK with fitting into the schedule since we had another heat pump working and space heaters. But they came that afternoon in the time promised. The technician diagnosed and fixed the problem. Only problem was my being at work and my wife didn't know about an Angie's List discount. Oh well, our fault. I didn't remember to tell her. The repair price was reasonable especially for the tight/narrow attic access. Timely, courteous and professional service has always been our experience with them.
Description of Work: One of the heat pumps stopped working. Found out that it was the start/run capacitor.

The installers were on time, professional and answered all of our questions.
Description of Work: We had a 31-year-old HVAC unit. We did our research and got several quotes for a whole new unit. We choose Brennan's for it's responsiveness to our request for the quote, the honesty of John (quoter). We could not be happier, the staff from beginning to end was very professional. I (not knowing anything about HVAC) have called a couple of times about silly stuff (how many times the unit comes on, the temp of what comes out of the vents) and they are great answering my questions and explaining the reasoning behind the differences. Brennan's even came back to my house just to put my mind as ease and again explained the difference from the older system and the newer one. We went with a company that was local, great reputation, with good reviews. We did not choose the least expensive quote but I'm glad we did...sometimes 'peace of mind' is worth a couple of extra bucks.

Rick Michaels did a thoroughly outstanding seasonal service on our furnaces to include one humidifier. In so doing he noticed a heater igniter element that was likely on its last leg and offered to replace on the spot even though we were his last stop on an already late Friday evening. This young man is an outstanding tradesman and homeowners should consider themselves extremely fortunate if Rick shows up to service your HVAC. We ask for Rick by name and are now solidly lifelong customers of Brennan’s!

I was pleasantly surprised by the honesty of the representative who came both times. He always offered several options and told us which one was the best for us (not the most expensive one!). The first time the AC failed, the unit was recharged, and we were told that we would need a replacement soon. Unfortunately, the unit failed again within a month, so we were offered several options for our home. Because our heating unit was pretty old, we decided to replace both units at once. The staff in the office was very responsive when it came to scheduling the replacement for the next day, and they helped secure 0% financing. I will add that both times we called this company, we did so after hours and left messages (since we didn't consider this situation an emergency). We received a call back as soon as the office opened the next day. The staff that came to do the replacement was professional and focused on the task. Overall, I will call again for all our heating and AC needs.
Description of Work: Our air conditioning failed twice. This company fixed it the first time and replaced the system the second time.

Quick, efficient visit from scheduling to the actual tech visit. Friendly tech. Professional. Clean. System is running better and I'm successfully aware and engaged in replacing filters at the intakes in my second floor (and not just the unit in the basement).
Description of Work: A/C in second floor of home was struggling. Had system check that included both need to change filters (d'oh!) but also need to replace capacitors in the AC unit. Went ahead and did capacitors in both units based on diagnostic test results.

They weren't the cheapest, but they weren't the most expensive either. Their quality was great. They were great. I would consider using them in the future.

Installation went well. The two man crew worked well together and were polite and courteous while working. They were patient in answering any questions I had as well. They also did a good final clean up of my basement and yard area when finished. As general feedback, I Brennan's service can't be beat in this area. The service techs are always on time and I can't think of a time I didn't get a 20 to 30 minute heads up call from the either the office or the tech to let me know they were on the way. I did not originally sign up for their preffered customer plan, but once I did, I was glad, because they mean it when they say they will get to you as a priority. I had used four other HVAC service companies over the 20 years I have lived here and had poor to horrible service before Brennans was recommended to me by friends. Pricing is fair and I can always get my questions quickly and plainly answered on the one or two times I have ever called their office.
Description of Work: I replaced my 10 year old Trane inside air handler portion of my heat pump when the coil developed leaks. The cost of repair exceeded 45% of the estimate of a replacement Trane unit. The unit went out in June when the temps were in the high 90's (of course) so they were a little backed up with other installations. They called five days earlier than the originally scheduled install date, the crew arrived on time and the unit delivered was crated / boxed and undamaged (I mention this because the previous company I used on my 10 year old Trane had delivered an obviously damaged unit with a caved in back panel that had to refuse to take delivery of).

Brennan's estimate came below another I received and guaranteed their work for two years. They were quick, professional and well priced. They did an outstanding job with the installation and addressing any questions or concerns that I had. Having worked in construction and the plumbing trade for 5 years I have a good idea of quality workmanship and the two techs who installed everything certainly had it. They were not rushing and took the time to do it right. I wouldn't hesitate to call this company again or recommend to friends/family.

Repaired the A/C and made recommendations for future purchase (system is about to go!). Total Cost was $332. I will be buying my next system from Brennan's becasue they were so good and fair.

I left a message over the weekend, and on Monday morning around 7:30am they called to say someone would arrive between 10am-2pm. They called around 12:30pm to say they would arrive in 30 minutes. The technician arrived within 30 minutes and diagnosed the problem as a short caused by a bug eletrocuting itself. He cleaned it out and had it working in 15 minutes or so.

Great. I replaced a 35 year old furnace and a/c because the a/c had burned out and I thought it was time to do the furnace too. I called, the estimator was here later the same day and I had to wait a week for installation but I knew that going in and I was okay with that. They arrived promptly as promised worked all day, 7 hours, showed me how to program the thermostat, re-connected my humidifier, used less space in my laundry room than the old system, cleaned up after themselves perfectly. I'm very pleased with everything. I received a Carrier rebate, a Brennan's rebate and Angie's rebate. I am pleased with the price.
