Brennan’s Heating & Air Conditioning Reviews

Timely and excellent service and installation as quoted. John provided all pricing and equipment options as requested by my wife and me to make the decision that best suited our needs and requirements. Communication and follow through during the entire installation process. Mike and Donny(installers) exceeded expectations.

DJ M. Lorton, VA

I’ve been a customer for a long, long time. My experience with the entire staff from the office personnel to the field techs has been exemplary. To a person everyone has been very courteous, professional, informative and an asset to the company. Field techs arrive as scheduled and work has always been professionally completed. All questions answered. Highly recommend Brennan’s HVAC to anyone.

William M. Woodbridge, VA

You guys did an excellent job! All service from your company has been first class. Over the years I have noticed very little turnover in personnel…to me that says something. Thanks much!
Drew R. Woodbridge, VA

Mike arrived on time and immediately assessed the problem we were having with our heating system. He was extremely knowledgeable and worked quickly to correct the problem we were having. I would highly recommend Brennan’s which we have used for years to service and maintain our boiler and air conditioning systems. Thanks again to Mike for the exceptional service.
David H. Alexandria, VA

Great service from Rick on HVAC diagnosis! I had Brennan’s replace my HVAC. Technicians, Marty, Edwin & Donnie, were very professional doing the install, explaining how system worked & final cleanup.

Two thumbs up for Brennan’s! They earned my future work!

Henry T., Manassas, VA

All the techs were extremely professional and left my work area in better condition than I did.
Bernard R., Woodbridge, VA

Brennan’s has been our ‘go-to’ HVAC installer for rental properties and our residence. I am very hard to please when it comes to service personnel, particularly if they do not keep to appointments or try and install unneeded equipment. Brennan’s is unequivocally the best we have worked with for over 25 years. I would happily attest to their honesty, integrity, and desire to earn your respect for ethical dealings. I am always asking, ‘who can you trust’ particularly if new to the area. Brennan’s is that company you can trust.
Edward G. , Alexandria, VA

We have been using Brennan’s since 2011 when we found out our townhouse needed a complete new furnace. We shopped around for the best price and we decided to go with Brennan’s not only for the price but the overall good feeling we got from the rep at the estimate. He seemed very knowledgeable and was very considerate of our home. We bought a new home a little over a year ago and immediately contacted Brennan’s to do an inspection of our new to us HVAC system. Everything was reported to be in good working condition which was great news. Last week we had a Humidifier installed, as air gets a little dry through the winter months. Once again the tech was knowledgeable and courteous. We signed up for the maintenance plan and will continue to have Brennan’s inspect our HVAC system twice a year to confirm everything is working as smoothly as it can be. Thank you for helping us take care of our home!
Brandon M., Oakton, VA

Dear Mr. Brennan,

I wanted to write to let you know how impressed I was with the service your company provided; your company exceeded my expectations and truly went above and beyond. I recently heard about your support for the ARC in Prince William County and I was further impressed by the compassion and generosity you return to the community. I will never use another company for my home or my rental properties. Karen Smith spoke so highly of you and that is as good as gold for me. Please know that I will also be referring anyone I know who needs your services. I can’t believe that I hadn’t heard about your company until this past year but I promise you there will never be another heating and air conditioning company in my homes.

Warmest regards

Jo-Ellen B.

Our 20 year+ a/c was running nonstop and we found it leaking inside. The Brennan’s person on the phone said to turn it off to prevent freezing up, and they would send someone out that morning. Adam the technician, arrived, checked the system out, found the problem and repaired it, and checked the rest of the system out. They called before the technician arrived to let us know he was on the way. The price was reasonable and the service was great! Adam was a true professional and did a terrific job – everything we would expect from Brennan’s! He didn’t try to sell us a new system, but we will definitely call Brennan’s when this one finally gives out!

Dear Brennan’s,

I have been a customer of Brennan’s for over 30 years and have received nothing but the best service from the whole team. Kelly is my lifesaver and always helps with my needs and gets me outstanding and timely assistance every time. Technicians Adam, Trevor and Tyler are outstanding individuals. Very professional and competent. Today this team installed my new AC/furnace and did an outstanding job. Brennan’s always delivers first class customer service, has very reasonable prices and financing and best of all they always stand behind their work. Can’t imagine ever having a different company. Keep up the great work.

John & Mary E., Haymarket, VA

Dear Brennan’s,

Today I had Tyler Ahern do a major repair on my system. He definitely displayed uncompromising customer service, superior craftsmanship, and a most pleasant and positive work ethic. I’ve been with Brennans for many years and even have you service my rental property. All workers are very good. I want to single out Tyler because he is over the top in my evaluation and I’m 65 year old and spent 31 years in the Marine Corps. He has the determination, professional presentation and tenacity to complete his work just like my best Marines that I had work for me. So I don’t say this lightly. If you are considering an employee for the month or a bonus, he’d get my vote. A real pro!!!!!! Thank you for a most enjoyable experience.

Mark P., Springfield, VA

Dear Brennan’s,

My furnace stopped Sunday, February 15th, (outside temp 9°F, inside 40°F) BRRRRR!

We found Brennan’s info in the five star rated “2015 Guidebook” and called for service. Gari Darr was at my home by noon. After inspection, he spent over one hour explaining why I should let my 31-year-old furnace R.I.P. while going over my replacement options. The next day install was scheduled for a new furnace. On Monday, inside temp of 34°F, Gari called at 7:30 a.m. as promised, to let me know the install would begin at 9 a.m.

The team of David Lianos and Mike Stinson arrived on time and worked 5.5 hours in 2° above freezing temperature to complete the job. They left the entrance and work areas spotless (booties, drop cloths, and brooms were used). They even push-broomed a portion of the front sidewalk. Gari Darr called at 6:30 p.m. to inquire if all was well and that I was thawing out.

Being a holiday weekend with record setting low temps, Brennan’s response, follow through and follow-up was exceptional. And these three employees deserve recognition.

I will sing your praises at every opportunity.

Michael D., Alexandria, VA

Dear Brennan’s,

I worked for Washington Gas in the Appliance Service Dept. for over 24 yearrs, and 31 years with the company. In that time, I saw examples of dozens of HVAC contractors’ work, both good and bad.

What I witnessed on January 27th, 2015, at my home was the work of the consummate professionals employed by Brennan’s Heating and Air Conditioning. The two crews arrived promptly in the morning to begin the replacement of my 2-zone gas furnace/electric AC systems, and worked non-stop until the job was completed before the house even began to get cold inside.

The crews’ work was beautiful, and the furnaces worked perfectly from the beginning. Neal Kincheloe is a very professional sales rep, also. Everyone that I dealt with at Brennan’s Heating and Air Conditioning has been very pleasant. I would highly recommend Brennan’s to anyone needing their HVAC systems repaired or replaced.

Karl W., Manassas, VA

Dear Brennan’s,

I am an incredibly picky and detail-oriented homeowner. My new HVAC system purchase starting with my service and sales with Gari, to my installation and debrief with Dave & Mike has been the best and smoothest of all my housework. All these deserve special recognition for being able to answer all of my questions accurately and helpfully. The quality of the install is superb; I wish Brennan’s did more than HVAC.

In addition, the pre-filing of all the paperwork was an unexpected and very appreciated touch.

Thanks to the front office for the extra effort.

John G., Lake Ridge, VA

Dear Brennan’s,

My husband and I did a lot of research before purchasing our new HVAC unit.  Brennan’s price was excellent and they offered financing plans that were very reasonable.   I was impressed and very pleased with the work of the two installers throughout the process. Both gentlemen were extremely nice despite the hot weather, especially during the time they worked outside. Please extend my sincere appreciation to the installers for their excellent work and again I thank Brennan’s for their prompt and quality service.  We have already recommended your company to our neighbor who is in search of a new unit as well.

Erin and Robert M., Springfield, VA

Dear Brennan’s,

We now understand why Brennan’s HVAC is one of Angie’s list top picks. From our first call to Brennan’s to schedule a sales call to the finial walk through with the installers. They all did an outstanding job! Neal, the Sales Specialist, was very knowledgeable and had a great no pressure style. Ed and Darryl, the installers, were very knowledgeable, took the time to educate us and treated our home with care as if it was their own.

Bobby N., Manassas, VA

Dear Brennan’s,

I appreciate the speedy repair on my AC system today by Brian.  He quickly diagnosed the problem and got my system working for a reasonable fee.  Great work!

Jocelyn G., Washington, DC

Dear Brennan’s,

Was not a Brennan’s customer prior to the installation of a new heat pump system on 6/26/14.  Found Brennan’s website very helpful. Brennan’s provided a cost estimate on the same day I placed my initial call.  Salesman then contacted me to see if I had any questions and whether there was anything else Brennan’s could to earn my business.  Installation was scheduled on a day convenient for me.  The technicians were knowledgeable, respectful and courteous.  My experience with Brennan’s to date has been a very positive one.

John W., Woodbridge, VA

Dear Brennan’s,

I was very pleased with the knowledge and level of service the sales, financing, and installation staff provided.

Joshua M., Fairfax, VA

Dear Brennan’s,

Love the new unit, work much better than our old unit. The installers were very professional, courteous and knowledgeable.

Jerry P., Woodbridge, VA

Dear Brennan’s,

I have moved all over the country and have had bad experiences with service providers but the experience with your technician, Fred, was a breath of fresh air. He was professional and knowledgeable. I would recommend your company to anyone.

Eric L., Dumfries, VA

Dear Brennan’s,

We have lived in our current our home for 26 years and previously owned another home in the area for 8 years.  Based on our experience, Brennan’s is by far the most responsive and ethical HVAC company in the area and has earned our business exclusively for the last 8 years.

Victor B., Woodbridge, VA

Dear Brennan’s,

Brennan’s replaced my heat pump and hot water heater.  Neal came to give me an estimate and was very helpful in helping me to understand the different options and answering all questions.  Pricing was very good compared to other vendors.  The installation team, Chris and Tyler did an excellent job installing the system and explaining how it worked.  They were very professional and cleaned up when they were done.  I will be recommending Brennan’s to anyone I know looking for heating and A/C services.

Nonie, Herndon, VA

Dear Brennan’s,

Thrilled your folks were able to inspect, diagnose & install new system all in one day. Great guys. They even put up with my watching them work. Very happy.

Doug R., Woodbridge, VA

Dear Brennan’s,

It’s comforting to know that I am dealing with a very reliable business.

Beverly D., Woodbridge, VA

Dear Brennan’s,

This home has been our residence since 1981.  Over the years many technicians have serviced our HVAC.  Adam Brown is the best of the best. If I could vote, I would vote to have Adam assigned to this account permanently.  Thank you for your efficient professionalism.

David Z., Vienna, VA

Dear Brennan’s,

I have been a Brennan’s customer for 20+ years and have always been satisfied, particularly with the professionalism & knowledge of the technicians. I would not consider using anyone else.

Ralph L., Falls Church

Dear Brennan’s,

We were very pleased with how quickly we were able to have our A/C replaced.   The technicians were very courteous and respectful of our house and belongings.  They arrived early, work was done quickly and we were back in a cool house by late afternoon.

Thanks, Brennan’s.  We will definitely use you again!

Paula H., Fairfax, VA

Dear Brennan’s,

Simply put, OUTSTANDING SERVICE! Friendly, experts with respect and who show up on time.  The best customer service of contracting technicians I have received in Northern Virginia since I relocated here in 2011. Brennan’s is definitely a positive company to work with who will deliver what they promise!

Stuart E. Woodbridge, VA

Dear Mr. Brennan,

I wanted to drop a few lines to let you know how pleased I am about the service your company provides. I have been using one of your Service Technicians, Patrick for the past several years and he has always been there for us serving my parents and now my own family. The service your company provides is outstanding. Patrick’s team that installed our new unit a week ago, did a superb job. They were courteous, polite, had attention to detail, and were very mindful about keeping all common areas clean. I can’t say enough about them.

After the installation of our new unit, as promised, Patrick stopped by to inspect the work and reassured us that everything was functioning as expected. He even took additional time to demonstrate how to operate the new thermostat and answer any additional questions we had.

You guys are amazing, you clearly have staff that love the job they do! Keep up the good work!

The Ingerick Family, Woodbridge, Va.

To Brennan’s

Last June, we had a Carrier Infinity furnace and air conditioning unit installed. We have been so pleased with both units! They are both very quiet, and provide even comfort throughout our town home. And we have seen a noticeable reduction in our monthly utility expenses. This has definitely been one our best purchases for our home! The installation was done on time and with care. Our spring service was recently performed by David Price and he did an excellent job! We highly recommend your company!

Mike & Jane B., Woodbridge, Va.

Dear Mr. Brennan,

It has been such a great feeling for the past twenty seven years knowing that you and your service representatives have always kept my heating and air conditioning units fine tuned and operating perfectly. Peace of mind is priceless!

I am writing this letter to thank you personally for all your kindness, compassion and professionalism over the years. I am especially elated that you, as a business man, and out of the kindness of your heart during these difficult times in our economy, have chosen to waive your professional service fee for me.

May God bless you and your company always and in all ways. I remember you, your family and your company in my prayers.

Gratefully yours,

Josephine D. Woodbridge, Va.

Dear Mr. Brennan,

Recently, I had your company install a new heat pump & a/c system in my home to replace the unit I bought from Brennan’s back in 1996. I want to compliment you and your staff for the fine installation and service we received during the process.

I was particularly pleased with the fair price and quick installation; and the two install technician’s (Danny & David) were most friendly and professional. I have been one of your customers for 13 years now, and I will continue to use your company and recommend it to my friends and neighbors.

James L., USMC (ret), Woodbridge, Va.

Dear Don:

I had a “Carrier Infinity 17” system put in yesterday. I wanted to send you this brief letter to tell you how happy I am with the way your entire staff handled the purchase and installation. My grandfather and father were in your business for 50 years but they did not have it down to the science and detail you have put in place. The four employees I was in contact with were Nancy Dempsey (who came to me recommended from previous customers), Kali Davis, RJ Borecky and Derrick Martin. You can be proud of them and your organization.


Ted F., Woodbridge, Va.

Hi Don,

I was prodded to write you after we received your Spring newsletter. It was so informative. Delighted to read you are on Angie’s List.

We have been thankful for a number of years now that we “found” Brennan’s. All of your technicians are exceptional. We called to express our appreciation for one of them, but actually we like each and every one of them. What professional’s. We’ve never said “Thank you” and later regretted it because we found something wrong with what they did. Your office personnel are also very good. You are fortunate to have this staff. And we believe this is a reflection on you. You must be exceptional.

A big thanks to you and your employees

Bob & Joyce Y., Lake Ridge, Va.

Dear Don,

I just wanted to let you know that I placed an emergency call last night (no heat) to your company and Gari responded immediately to my needs. He was quickly able to identify and fix the problem, restoring heat to my home. Chris and Patrick have also worked on my furnace and I was very pleased with their work. As I happen to work for the Chamber of Commerce, I appreciate your membership and proud to refer your business often.

Thank you,

Lynn A.

Dear Brennan’s,

The scheduling for the final inspection went very smoothly and the Fairfax County inspector was very impressed with the installation, stability of all connections, neatness of work and thoughtful attachment of instructions to the unit.

I’m grateful to your entire company for making this such an easy transition, I can’t say enough how pleased I am. Once again –Many Thanks

Joyce C., Springfield, Va.

To Brennan’s

Thank you for your extra effort in having Gari come by today to make A/C repairs. I know this time is very busy for you and I truly appreciate your extraordinary service. I also appreciate your attention to detail and professionalism. I know a typical response would be for my phone call to be returned Monday morning and to be scheduled first come first serve. Nancy was understanding of my situation and very helpful in accommodating my schedule. I’m impressed and thankful. Also Gari was very courteous and professional. Again, thank you


Jack A., Lake Ridge, Va.

Dear Mr. Brennan

I want to compliment the services that Brennan’s provided to me recently for installing my new heat pump. I was impressed and very pleased with the work of the two installers throughout the process. Both gentlemen were extremely nice despite the hot weather, especially during the time they worked outside.

Please extend my sincere appreciation to the installers for their excellent work and again I thank Brennan’s for their prompt and quality service.


Mrs. Wallace D., Lake Ridge

Dear Mr. Brennan

Please pass along our thanks to your installation team for the work they accomplished for us. They are clearly technically skilled and professionally proud of the work they do.

Clearly the job was not straightforward since they worked in a confined space throughout the day, but the care and attention to detail in their work is clearly evident. Neat, clean and tidy – a real bonus in any installation team working in homes- showed a great level of pride in their work. We personally appreciate the time taken to make sure we understood the operation of the new system.

We gladly commend these professionals and believe that they well represent Brennan’s. Once again, thank you.


Roger & Jennifer N.


My wife and I would like to highly commend two of your technicians, Derrick and RJ, who installed a new air conditioner, furnace and humidifier in our home.

They were courteous, efficient and highly knowledgeable. They not only did an excellent job installing the new equipment but left the area completely cleaned. We would also like to thank Nancy Dempsey for her help in working up an affordable contract for us.
