Our Rave Reviews

  • There were no uncertainties in their quote and they were willing to do the work immediately so we wouldn't be without hot water over night. They took care to keep the house clean while moving the old heater out and bringing the new one in. They worked quickly and efficiently, and left the space cleaner than they found it. I definitely would do business with them again. Berry P.

  • BMS is the BEST! I just want to take some time to try to express my incredible gratitude. I also found BMS through a good friend Jason Normoyle. My new HVAC unit is working wonderfully in my condo. Your company really was such a joy to work with. I still can't believe that you guys were able to get in here in such short notice and save me from that July 4th heat wave. :) I don't know what I would have done with temps over 100 and no AC. But, you guys saved me! All of the guys on your team did such a great job and were so polite. I wouldn't choose another company to work with. Thank you so much again for your incredible service. A customer for life. Quality Work and Unmatched Customer Service I employed Brothers Mechanical Services/BMS to work on my house, as well as my Grandma's house. Both times they arrived as scheduled, and even the same day in one instance. TJ was very knowledgeable, and was straightforward with pricing. I was so pleased with the service, I recommended them to a friend. They were able to get to her house the very next day, and replaced her AC unit for a great price! I have never seen a company in any industry that has as high a level of customer service than that of BMS. Thank You!! "All of the techs were very professional and knew exactly what needed to be done. They provided same day service and their team explained everything that needed to be done. Great team, great service, great price!" Scott T.

  • I want to tell you what my tenant said about your company's installation service. She told me in her email today: “MS was very polite, clean and considerate (they were here all day, so they tried not to get in our way). The unit looks great, of course and the thermostat is really neat and easy to program. It was worth the wait!" Being so far away in West Coast, I felt a big relief when I read the above comments from my tenant. I want to send you this personal note to say "Thank you". Please also extend my appreciation to your other technicians. I won't hesitate to give out my recommendation of your company to my other friends in VA. Excellent job! Stella

  • My family and I wish all the best to you and your company. You not only helped us in a time of need, but have given us comfort in knowing that we have a trustworthy resource in the future. I feel like I can't say enough good things about you all. Midwest Regional was extremely prompt, professional, knowledgeable, and fair. I needed a roof repair done during the first big snow of the season. Their contractor answered my call late at night, came out first thing in the morning, and was finished by the afternoon. In fact, they had the job completed before other contractors even called me back! They gave a very reasonable estimate and were thorough in explaining all repair options and expenses, as well as where costs could be cut. They paid attention to detail and really went the extra mile to make sure we were satisfied. I felt like they treated my home as their own, and would recommend them above any other contractor in the Twin Ports. The Hise's

  • We cannot say enough good things about BMS HVAC/R and Harry and his crew. Our HVAC system needed replacing so we started the tedious task of calling out for estimates and reviewing numerous companies. Harry impressed us from the beginning with his professionalism and knowledge of what unit we specifically needed for our home. Other companies tried to tell us we needed to upgrade the size of our AC unit, but Harry explained that was not needed. He also explained our unit needed to be moved out from under our deck where it would receive more airflow. No other company explained this to us. Though their quote was affordable for us, it certainly did not compromise on quality of installation or the professionalism of BMS. On the day of install, installers were actually there early and took their time to make sure everything was installed correctly. Harry showed my husband exactly how to use the thermostat and how to use the system and filter. Later that night we smelled remnants of gas from when they replaced the system but they even came out during peak traffic time in order to make sure nothing was leaking and the system was installed correctly and our home would be safe. We would not hesitate to use BMS HVAC/R for any other home project. In fact we need our water heater replaced soon and they will be the first we will call! We would recommend BMS HVAC/R to our friends and family based on our wonderful experience! Audrey M.

  • To the ownership of BMS HVACR: I wanted to express how satisfied we were with our recent business transaction. After a wonderful vacation spent out of town, we came home to a sweltering home (100 degrees inside) on July 30. It was apparent that our entire HVAC system was going to need replacing after 23 years of heating and air conditioning our home. We spent several days researching government websites, talking to neighbors and friends, scouring energy star websites and blogs before narrowing the choices down to 3 local companies. Monday, August 1, BMS was the first to respond to our call as well as the first company to come on site for an estimate. Harry was efficient, patient, and friendly as we interrogated him with all of our questions regarding his company, Trane units, and his work. We were so impressed with Harry, the system he put together for us, and the cost, that we assigned the job to him on the spot. Thursday, Harry arrived in the morning with a wonderful crew that included T.J., Mike, and Josh. They were all professional, hardworking, thoughtful, and extremely clean. Harry took the time to teach us how to use our new system as well as the new thermostat. It works flawlessly as we watched the temperature lower from 90 degrees when the unit was installed to 75 degrees within 4 hours! We are thoroughly impressed with your company from the initial response to the finished product. We can't say enough good things about your company and will continue to spread the good word to all of our friends, family, and neighbors. You have a customer for life! Greg & Heather

  • BMS people provided great service. It was middle of the night, I called 15 ER HVAC companies only one actually picked up the phone and talked to me about my furnace, they sent their well-qualified service technician over to my house in matter of 2 hours & had my heat working in no time. With my new born 2 moth old I am thankful to these people. Great job BMS. Peter S.

  • #1 in my book! Over the summer my mother's ac went out. Panic we were giving the Brothers Mechanical Services Hvac from an online ad and the service was outstanding. We had called several companies and they came within 30 minutes. There service was wonderful they went way beyond what we'd expected. They were professional, competent, and explained everything that was needed. The situation with the ac was fixed within 30 minutes and cost far less than was expected. My mother is 83 yrs. old and this could have been a real problem for her this company was kind and reassuring to a senior and I am very grateful for their help. I will only call this company to service my house and have recommended them to all of my friends who are always looking for true honest and reliable service. Catherine
