Tim Brennan was prompt in responding to my phone calls, provided a free proposal, and was knowledgeable of the business and equipment that was installed. He came on the days scheduled and on time. Explained the work that was to be performed and was open to my input prior to the work being done. Good attention to detail and cleaned up work areas. Experience was satisfying and professional.
Description of Work: New install of central air to our Colonial Garrison home. Consisting of an American Standard split system in the attic to cool the 2nd floor and two(2) Mitsubishi Mr. Slim Ductless installed on the 1st floor and family room. This setup gives us three(3) zones for better climate control in the spaces they are cooling. All three are Energy Star rated.

The air intake was deemed unnecessary and the source of the water in the heater was not determined. A general cleaning was done (the unit was vacuumed) and that's it. We were not satisfied with the visit and our service fee was refunded in full. I was impressed with his integrity and feel my job was not a good fit.
Description of Work: An energy audit was done on our home. It was recommended that we reconnect the fresh air intact on the heating unit. Also, there was water/condensation collecting in the heater.

Just the one phone call. I had googled furnaces, replaced a couple parts, and it still wouldn't light. I ended up calling someone else, they came to look at it, made a suggestion of what it probably was, and I finished the job myself. All that was still wrong was a blocked tube.
Description of Work: We only got as far as them calling me back. My furnace had it's base flooded and wouldn't light. Even though I assured them no electronics had gotten wet, they seemed confident the furnace was unrepairable. I insisted that replacement was not an option. They said they would call me back the next day. That's the last I heard from them. They may be wonderful at actually fixing things, we never got that far.

They are great. The owner, Tim Brennan, is really personable. We could tell that he was as honest as they come. He got right to the problem and there is something else that is wrong with our furnace that is a big expensive fix, but he was able to do a fix that will work in the meantime until we decide to fix the other one. We believe that a different service provided would have gone ahead with the expensive fix and not given us that option. He called us back right away. We will absolutely use him in the future.
Description of Work: We used Brennan Cooling & Heating to fix our furnace because it was having a drainage problem.

The estimate was fair and it was the lowest that I got. My experience with them was very positive. They were very responsive and easy to work with. We didn?t use them since we needed some condo approval for getting the work done. They seemed competent but it?s a complex job. They were friendly and casual. We also got an estimate from a different company which was a little higher.
Description of Work: We received an estimate from Brennan Cooling & Heating about 3 or 4 weeks ago for installing a ductless system in my condo.

My furnace died towards the end of October. With winter coming fast, I was hurrying to find a good heating company to replace it. I called Brennan Cooling and Heating, and Tim came out the very same day to have a look. He spent quite a while with me showing the different options I had. In the end, I chose a new hybrid heating and cooling system. This would replace both the very old furnace and A/C units with new highly efficient ones. This was the best choice for me, as all of the companies I had spoken with recommended changing the very old A/C unit at the same time. Tim ordered the new system and did the work within the week. The installation looks great, and the new unit performs fantastically. Not only was the experience great, but now I am looking forward to those lower heating and cooling bills.
Description of Work: Replaced old furnace with new hybrid heating and cooling system.

My AC unit broke in the middle of a heat wave I called at 9:30 AM expecting a long wait. Two rooms in my house are rented and my guests had roasted the night before. Tim immediately understood the situation and said he'd be by around noon. He arrived at 11:45 AM; he was ready, polite and professional. He fixed the problem in less than a half an hour and explained everything clearly. I couldn't have asked for a better experience with a repair.
Description of Work: The compressor on my central air conditioning stopped working and he repaired it.
