I canceled my service contract after the 3rd missed 1st call appointment! What's the point of making a first call if you never get put on the schedule or the tech never shows up. Also, when they do show up the techs just like to complain about the company and tell me how the owner isn't really interested in the residential side of the business! Not wasting my money of this business anymore!

Okay, I have to give these guys the best review there is. We had a problem with our AC that happened in March. Home warranty company sent 3 different companies ALL three gave us different problems, tried to ""fix"" things while basically destroying our AC unit as a result. our neighbor recommended Trademasters. I called and Dan came out the next day and checked our unit. He was very quiet and professional. He took his time and checked everything and ended up telling me what the actual problems were. He also recommended replacing the whole system since the problem was more severe than I was informed by 3 other companies(each tried to solve the problem by fixing the parts). Note this was already in June. We decided to get a quote to see how much it would cost to replace the system. Sean their sales rep came out and gave us the best offer he could without trying to upsell his product. He left me with the pile of information to read including the recommendations. He also made sure to accommodate us if we decided to go with the installment of new system since it was the busy time they were booked out three weeks in advance, but he understood our situation having a small child and a dog and they prioritized us. They came out within three days of our decision and installed new system, provided certification and inspection instructions. The city inspector came out checked everything and everything looked great. I just can't thank them enough.
If you are looking for a pressure-free, stress-free company you should defenetly call them

Simply put... they ""inspected"" our hot water heater, per condo rules... and 3 weeks later, there was no hot water. Resulted in a $500 repair to our hot water heater. Beware.

So I had my air conditioner and water heater inspection per my condo rules. 12 months ago I was told my coolant was low and leaking and I should consider a replacement, which I'm more likely to believe. Today a guy came out (and honestly I don't think he ever inspected the ac unit because I didn't see him go back behind the building) and he says nothing is wrong with it. Huh? Did it fix itself? Did my coolant refill itself?! Either the first guy lied or this new guy has no idea what he's doing. Either way, I won't be renewing my agreement. I want a company that provides consistent and reliable service every time, regardless of which representative is sent to my home.

Oh and I know for a FACT that he didn't inspect my water heater because it's in the bathroom and he never went in there. He gave it a pass though. SMH

I seemed to be collecting a list of vendors I would NOT use Again. I finally found one I will. I didn't realize that many HVAC and plumbing firms PAY their technicians a commission on what they sell in your home. Once I learned that ... it explained a lot about the vendors I didn't like. Trademasters has salaried employees who are dedicated to their profession and work to provide you with the right solution for your home and budget. When I asked about putting in a NEST, my technician shared with me the pluses and minuses and spent the time making sure I understood my choices. When the heater just failed, they got someone here to take care of our issue within hours (it was a really cold day.) It's nice to know there are some GOOD companies out there that still do the RIGHT thing.

We had a porch added and wanted some sort of HVAC solution to widen the season. We called Trademasters and they came up with a split system. It is unobtrusive, provides heating and cooling and we are very happy with it. In the hottest of days it brought the temps down quickly (we only have it on when we are out there). The guys who installed were friendly and worked fast- coordinating with the porch crew. We have used Trademasters in the past and will continue!

Have been using Trademasters for years. They've always been dependable and perform quality work. Most of the technicians have been courteous, friendly, and informative with respect to explaining the work they are doing and why. They always come in with shoe protectors when working inside the house. When one of the A/C compressors died outside, we elected to replace both Comfortmaker HVAC systems original to our house with two new, more efficient Trane systems installed by Trademasters. They aren't the lowest priced, but they've always been fair and reasonable on price, and given the quality of workmanship and good people Trademasters sends to our home, I've never hesitated renewing the service agreement with them each year.

Really like these guys. The technicians are very friendly and good at what they do. The ones I've had have been really helpful asking what my heating/AC issues are and trying to help me through it. Even the people you talk to when you call are very friendly and accommodating. Really glad I signed up with them.

Trademasters have been our preferred HVAC provider for nearly 20 years, over the course of three houses we've owned in Arlington during that period. They are unfailingly courteous and efficient and always responsive to our needs, be they the regular bi-annual system maintenance or the occasional equipment problem. Their rates are fair market but they provide supreme value for our dollar.

An added benefit of using Trademasters is that they also provide plumbing services. It makes it so easy to just call one service number for virtually all our HVAC and plumbing needs. From the front desk staff to the experienced journeymen who show up at our door, we love the Trademasters team!! Highly recommend!!

I needed a full HVAC replacement in my ~2000 square foot condo. External condenser, internal evaporator, furnace and blower. I live on the top floor(s) of my building, so the install also required a crane to get the condenser up to the roof.

Shane was very friendly when he came out for the initial inspection and estimate. He explained everything in thorough, but layman, detail so I knew exactly what was going to be done, I understood the scope of work, and even recent legislation that required specific system choices (type of refrigerant, etc).

The workers were very efficient, friendly, and professional. They laid down tarps to cover all of the carpets they had to walk on and/or work around. Even when I had the door propped open if the 'outside' guy (the one working on the condenser) had to come inside, he'd still knock.

Once finished they walked me through the manuals, guides, etc for the system. They showed me the emergency cut-off and moisture cutoff systems they installed. Showed me how to clean the u-bend they installed for the condensate...basically walked me through the whole care and feeding of the system.

I got multiple quotes from HVAC vendors around NoVa, Trademasters weren't the cheapest, they were close, but they were also the most professional, seemed the most interested in forming a business relationship with me, and were the highest recommended....a recommendation I now share and freely provide.
