Brennan's Heating & Air Conditioning Reviews

Justin Patton was my service technician, he was amazing. Immediately diagnosed and explained my situation within 30 seconds of looking at my setup. He serviced my units, thoroughly explained everything, gave me all kinds of tips on how to manage my system to ensure I extend the life of my unit. He was extremely knowledgeable, and had no problem sharing it with me. He didn’t try to sell me something I didn’t need, and the prices were very reasonable. I had a great experience with Brennan’s, I will be requesting Justin specifically for my next service, he was awesome. Read Less

I have had Brennan's deal with my heating and air conditioning issues for the past 30 years in my primary and rental homes. The are absolutely excellent. After I moved to Florida, they were the main reason that I could keep rental properties in the DC area. Whenever there was an issue, they were on the spot and dealt with it quickly, efficiently and professionally. When an ice dam crashed down on the compressor at a rental property (in the middle of a massive snow storm) they provided excellent temporary heating until they were access the property to replace the flattened compressor. But that's just one example of many such heroic actions over the decades. As I have sold properties in the DC area, I have always left an active service contract with Brennan's so that the new owner would get to know them. You really just can't do better than Brennan's in the DC area. Read Less

The entire experience with Brennan’s has been excellent. It started with the knowledge and helpfulness of Adam the technician who diagnosed the problem and presented the options that were available to me. Billy Moore and his staff designed a system to fit my needs and my budget. The installation technicians Anthony and Danny did a great job explaining the new unit, explaining the new thermostat and they made sure the everything was left in a clean and neat manner. Billy Moore came by after the work was done to make sure it was done correctly and answer all of my other questions. I would highly recommend Brennan’s for any of Heating and Air Conditioning needs.

I've owned two other homes in Woodbridge so when I purchased my current home I hired Brennan's to service it. Long story short, the system stopped working, they repaired it, but I ordered a new system anyways as I had no faith in the current system. Brennan's priced out a top of the line system for me (my request) and ordered all of the components. Marty and Waldir came out on the scheduled day (the office called to let me know they were on the way). When they arrived, the introduced themselves, I showed them where everything was and they went to work. The were extremely respectful of my flooring (laying runners) and cleaned everything up when they were done. They used a real shutoff valve for the humidifier and not a cheap saddle valve. The even cleaned up the PVC drain pipe creating a shorter and cleaner run. When everything was done, Waldir walked me through the routine system maintenance (changing the air cleaner filter, humidifier filter, and drain line). Finally he walked me through the smart thermostat set up. I had problems getting the thermostat to update but using the Carrier web site and a micro SD I was able to install the update and everything is working great. Extremely please with the operation of the Carrier Infinity System and the install. This is the fourth system I've had Brennan's install for me (one in the first house, 2nd house had 2-systems) and I trust them to install quality products and install them correctly. They have always exceeded my expectations. A great local company to do business with. Read Less

Mike Brennan and his outfit have been supporting our HVAC systems since the early 2000's. Rick Michaels is our current superstar -- excellent at diagnostics, very knowledgeable of the systems, detail-oriented and careful in his work. A more recent addition, Britt, is also a strong player -- Brennan has been finding some real pros to support the outfit, and good techs make all the difference to the customer. Fair price, responsive day and night, and technically capable team -- can't ask for more. Read Less
