Last year my HVAC was on its last legs. It had lasted 30 years but after another repair the…read moretechnician said he couldn't guarantee that our old HVAC would make it through another winter. FH Furr (via Costco) quoted us about $29K. KD Mechanical quoted us about $18K and we went with them. The installation occurred over 2 days in October 2022 and was done in a very professional manner. Notably, we had a problem with the master bedroom (which sits over the garage) being cold in the winter months. We discussed options with KD Mechanical - including running another line into the master bedroom. In the end, we decided to wait until after the new system was installed and then reassess. With the new system and a sensor in the master bedroom, that room is no longer cold in the winter months. Unfortunately, several months later we found water spots in the ceiling and walls just below the HVAC unit in the attic. We called KD Mechanical and they identified and fixed the HVAC leak free of charge. Not only that, they also sent out a drywall repairman to repair and paint the stained walls. Again, KD Mechanical took care of the expense. I could NOT be happier about going with KD Mechanical for my new HVAC system. Bryan Leesburg, VA

I found Rapheal P. from Donmar to be easy to work with, the prices were reasonable, and he didn't try to pressure me into buying extra services. The capacitor had a 1 year warranty which was great because a few weeks later, a field mouse somehow found its way into the housing and shorted the darn thing, so it had to be replaced. I would definitely recommend Donmar/ Raphael! Rest in peace little field mouse.

First the GFI was not working property, I couldn't push the button and reset it after several tries. Bob, the Senior technician according to the email this company sent me, was able to push the button and made it work. So he told me that my home warranty won't pay for the replacement if it works. OK, fine! The next problem is the ventilation fan above the stove that was in the ceiling that won't turn on and there is a switch that we suspect was the control. He took off the plate of the switch, and told me that the switch had no electricity in it. And I asked him if he could figure out if it was a bad switch, a bad breaker, a bad or the wiring or the fan that is not working. He replied: "I don't know what that is, and I have never seen it in my life!" "I won't touch that greasy thing!" I told him it has been cleaned by professional cleaners twice and acknowledged that it was still greasy, but asked him if he could wear a gloves to at least to look at the fan. Nope! Bob just walked off the site and told me that he would refer me to another company. What a diva! Even though I am not an electrician, I have seen several fans like this in old houses. For an electrician who is not hired to strut the runway but solving my problems, this diva is not up to the job! They took more than a week to send someone but that person is not here for work. What a waste of time! The following day, a handyman came and figured out that the wiring in the switch was reversed and he corrected it, took the cover of the fan off, cleaned it up and made it work.

January we called because our hot water heater was leaking. Bowman's came out quickly (for a $130…read moreservice charge), confirmed it was leaking, and told us it was under warranty. We were informed they would contact us within a few days to schedule the replacement. More than a month later, after numerous unanswered calls and messages, I finally reached someone who scheduled the replacement for the end of that week. However, we were then told the labor cost would be $1,500. The installers themselves were great, but unfortunately the experience with the company left a very bad impression. The installation took a little over an hour, and when I called to ask about the labor charge, I was told it was simply a flat installation fee. It felt like the warranty ultimately provided little value because the labor cost essentially offset any benefit. I reached out to discuss paying what seemed like a fair labor amount and to see if there was any flexibility, but true to the overall experience, my call was never returned. There are too many companies that value customer service and long-term relationships to continue supporting one that doesn't respond or work toward a reasonable solution. Losing a long-time customer may not matter to them, but it matters to me. I would recommend looking elsewhere, as my experience was that the warranty meant very little, communication was poor, and management never made an effort to resolve the situation. Reading other reviews, it all makes sense.

The office manager, Jennifer, was rude and curt on the phone when scheduling yet another service call to my house. Again she would not provide me with a name or contact info to escalate this saga. The only reason I continue to use Bowmans is the warranty. There are many, many other choices of companies for others. Choose wisely, not Bowmans. June 2026: We are now six months without HVAC and I just found out Bowmans never ordered the parts to repair my HVAC... even though it is fully warrantied for parts and labor by them. And now the office manager Jennifer will not return my phone calls after getting American Standard (Trane) involved. May 2026: My HVAC system is under a parts and labor warranty with Bowmans. However, they have failed to properly service the system or obtain the necessary parts to complete repairs for over four months. As a result, we have been left without both air conditioning and heat. Despite the urgency of this issue, there has been no clear timeline for repair, no meaningful communication, and no resolution. Their lack of responsiveness and failure to act demonstrate a concerning disregard for the situation.
