Recently, we had Trademasters replace an aging furnace and air conditioner system. In addition, they installed a damper system with a second thermostat for the second floor, which allows us to set the temperature separately for the first and floors. The difference in the upstairs temperature has been astounding! Where it used to be an oven, it is now very comfortable. From the initial call to the final installation, their team was prompt, friendly, and exceptionally responsive. What really set Trademasters apart was their approach to helping us choose the right system. Instead of pushing a high-pressure, one-size-fits-all sale, their technicians took the time to discuss multiple equipment alternatives with us. They walked us through the pros and cons of different brands, efficiency ratings, and installation options so we could make a confident, well-informed decision. We couldn't be more happy with the final result! It's rare to find a team that combines top-tier technical knowledge with genuine, customer-first service. If you want a trustworthy HVAC team that shows up on time and truly knows their stuff, call Trademasters. Highly recommend!

I cut out the drywall ceiling, identified the joint where…read morethe pipe was leaking, determined a third floor toilet was the source of the water, set up a bucket, and then called swiftpro. Tyson came out and quickly determined the leak was not coming from the joint but rather from somewhere above. So now there was a mystery leak hidden behind the walls somewhere between the third floor and the basement. He suspected the pipe to be behind and certain section of wall on the middle floor and thought maybe a nail could be the culprit and checked to see if we had anything nailed to the wall, we didn't. So he had to pick a section of wall to cut behind to check and on his first try found the pipe and showed me exactly where the previous owner put a nail through the toilet drain pipe. I was originally concerned we'd have to open many walls and ceilings to find it and I'm still wondering how he found it so quickly. He also answered a ton of my questions.

Called Friday morning and the receptionist was amazing and got someone to our house that morning. Full diagnostic told us the compressor went bad. Our unit was 13 years old, so it was about time for a new system. We decided to replace whole system as replacing a compressor is quite expensive basically half the cost of a new one. Mike came that night to price out a new system. I got two quotes from other companies. But decided on Shanahan because of their reputation, service as well as pricing. Talked with Mike and Conner (the owner) about our options and they came on a Saturday to install even though they didn't have an opening until Thursday. The owner himself came with a couple guys and replaced our system. They were very polite, did excellent work and we were back up and running. Plus they had very affordable pricing. These guys care! Use 'em. We loved our experience from start to finish!

This is a great company! Sam, John and Joseph are conscientious about their work and the products…read morethey sell. I was referred to Winds of Valley by a company in Southern Virginia that does not work in NoVa. When I contacted Sam about my Bosch condenser that stopped working, he came out free of charge to diagnose the problem. Sam immediately noticed that the condenser unit was not matched with the proper blower and evaporator. The company that installed the Bosch system made calculation errors and told me that the two different devices would work well together; they didn't and quit working after about 2 years. Sam gave me his suggestions, showed me his prices and let me make my own decision. I made my choice and was still skeptical. Sam literally wrote into the contract that I had a year to decide if I was happy with the equipment he installed and that if I wasn't, he would replace what he installed. I never took him up on that offer. The system he installed is quiet and dehumidifies the house, which is something my other system did not do, even though I was told it would. Sam, John and Joesph removed the old components, installed the new ones and cleaned up everything. They swept up after themselves, removed the old stuff, the new boxes and made sure I was happy with everything before leaving. They also walked me through the settings on the new thermostat. They also provided a year of maintenance with the system. Two years later, I replaced the water heater and again called Winds of Valley. The water heater replacement process was as smooth and efficient as the process for the HVAC system. Sam is a small business owner who knows what it means to provide great service, use quality products and keep customers happy. If all contractors were as good as this company, contractors would have a better reputation. I have complete faith in Winds of Valley and highly recommend the company.

The young lady who answered our call was courteous, friendly and professional. I was very pleased with their ability to get Patrick out to our house the next day. Their service fee seemed reasonable and I felt comfortable with 90% of Patrick's advice. His service seemed thorough and quick. I know just enough about a/c units to have an idea of what was wrong and Patrick confirmed- the system was low on R22 refrigerant (Freon) and the coil for the compressor had gone out. He replaced the parts, but told me that it wouldn't work for long because it was very low on R22 and there was no more R22 available. He explained the history of R22, which I already knew most of, and told me the only option was to replace the entire system. This is where I became nervous because he quoted a price off the top of his head for a new Carrier system. In my profession we say that "the appearance of impropriety is as bad as the impropriety itself. How could he possibly know the exact amount and instantly recall the number? He hadn't even seen the interior unit or duct system, but said it was all inclusive - $9,500 installed inside and out. His next statement made me more concerned as it is frequently used in high pressure tactics. He said that if we decided before June 1, he'd deduct the $500 service charge from the install cost. I asked several questions to explore the issue, but he quickly shut down the questions with the emphasis on how little time I had to decide. He reminded me several times that the current a/c was not repairable due to the R22 issue and that it wouldn't last without R22. He made it clear that R22 hadn't been available for two years. Due to Patrick's statements feeling false to me, I googled it and to my surprise- Freon is available from many suppliers. I was even able to order it myself as long as I ordered it in 2lb containers or less. I was beyond upset and after a few emails received a call from their GM Tim. He danced around the statements for a while before saying that Patrick had told "half truths" about Freon. It is available, but his company chooses not to stock it- although he later acknowledged he has a 25lb can of it in his service truck. He denied that Patrick was trying to sell me a new unit using false statements and again called them half truths that were the result of poor training. Regardless, my 72 yr old neighbor who recommended them was also upset about the "half truths" she was told that made her buy a new a/c. I'm pleased to say I found a different company that is happy to install my Freon for a $90 service call. They can call it half truths all they want, I believe it is called theft by fraud and although I'm not familiar with Virginia laws- in every other state I've lived in this is called Financial Fraud of an Elder in the case of my neighbor. Please be careful- bigger isn't always better. Ps- Tim referred to company as "ARS" which could explain a lot. American Residential Services is a massive corporation out of Memphis, but DM Select claims to be a "small...family owned business" on their website. Something doesn't add up, but that's not for me to decide- I'll refer my neighbor to state criminal investigators to figure out what lies may have been told and if those lies constitute a criminal violation. Update- I found out just how badly they ripped me off when I jumped online to check the parts the installed. One part was under $12 and the other was available for under $30. The technician took less than 15 mins installing both. I believe these people are straight up criminals and you should avoid them at all cost.
