Energy Efficient Retrofitting
If you have heating and cooling equipment over ten years old, you could significantly improve your costs by upgrading — up to 30%.

Upgrading saves money because new equipment uses less energy, has less down-time, and costs less to maintain and repair. The upgrade costs are usually made back in energy savings in a very short time. It’s a win-win for both the environment and your budget.

Trademasters uses the latest state-of-the-art equipment and methods, applying a comprehensive approach to retrofitting that ensures your HVAC system’s efficiency, reliability, and safety. Energy Star rated heating and cooling equipment can help you save on costs and meet new environmental standards.

Our Client Care Agreement includes scheduled maintenance, which will keep your equipment running at peak efficiency, extend its life, and increase its reliability. Should you need emergency service, our CCA customers are given PRIORITY service and a 10% discount on repair services. Our experts can also conduct Performance Evaluations and Energy Audits and suggest ways to optimize climate control and resource usage for your particular needs.

We had a fantastic experience with Trademasters installing a ductless 1-room hvac system in our basement. They were extremely responsive and helpful, explained everything, charged a reasonable price, and gave us exactly what we were looking for. Great service, great product, great value.

Trademasters inspected our water heater & A/C as required by our Condo HOA. The tech was friendly, professional and showed up on time. The fee for their service was fear and reasonable. We decided to obtain their annual service contract for our Heating and A/C.

We have used Trademasters for almost 25 years. Their service is excellent and timely. We have never had a problem requesting emergency service. They are always accommodating. We recently contracted with Trademasters for a new furnace, air conditioner and hot water tank. All three jobs were done on time on the day they were scheduled. They were in and out in a few hours. There have been no followup issues. A job well done by the Trademasters staff.

Being in the commercial real estate industry for the past decade, I have worked with countless contractors. When it came time to evaluate overhauling my residential HVAC system and water heater, I received a few quotes from vendors and was then referred to Trademasters. I instantly felt confident with this vendor from the onset while meeting Shane for over 2 hours for the initial site visit. After several subsequent calls, given the project's scope and financial investment, we released Trademasters and could not be more satisfied. I was overly impressed by the prompt communication by Tabatha and the team at the main office from pulling the permit, scheduling around inclement weather and meticulous record-keeping of all necessary documentation.Further, I was blown away by the attention to detail, work ethic and ability to quickly problem-solve the day of the installation performed by Chris P., Chris F. and of course, Phil. They truly went above and beyond. I can genuinely state that I will be referring Trademasters to clients & friends and cannot wait to get them on board for my commercial projects!

Trademasters was quick to provide a quote for a replacement HVAC unit. Price was responsible with no "hidden" costs. They were sure to include and explain the little things that really make a difference that we would not have even though of as a homeowner. Things that seem “small” but are worth it such as a trap we can see and clean, a drip pan sensor and float sensor to detect leaks and clogged lines to prevent water damage to our house, and a new equipment pad and risers for the outdoor unit. Really appreciated the honesty and transparency of the quote. They additionally provided great information for us to decide on the type of replacement unit we wanted/needed. They answered any questions we had promptly and thoroughly. When the two technicians arrived on site they were on time, professional, and incredibly knowledgeable. They wore face masks (COVID), shoe covers, and laid down a drop cloth from the front door to the indoor unit to protect the house during their work and trips inside and out. They were impeccable when they cleaned up their work inside and out. They were extremely professional, hard working and efficient during their time here. The orientation of the new unit, explanation of the initial startup, testing of the unit and all the details of the work completed were above standard. Trademasters really goes above and beyond from start to finish.

I'm giving Trademasters five stars thanks to the five-star service we received. We recently had our ancient (and dead) HVAC unit replaced by this company and the quality of work was excellent! Also, the staff worked with a high level of professionalism.From our initial estimate meeting with Shane, I was very comfortable with his knowledge and was confident that they could do the job, which wasn't and easy one due to the age of our previous unit and the orientation of it. Shane gave a competitive quote and we decided on Trademasters largely due to his understanding of the situation and his experience.The staff worked from 7 am to 4 pm. It was an all-day job, but they got the work done earlier than previously estimated. Safety precautions were definitely taken and the technicians kept their masks on for the duration of the work, which alleviated any concerns. Once that air conditioning kicked it, relief was granted! Payment was easy as well and the office staff did a great job coordinating everything.Awesome service and highly recommended!

A Saturday air conditioner emergency was the reason for the call. I am so grateful to the technician that came and helped me out. He was very professional and knowledgeable and resolved my problem quickly. I owe him a big thanks for getting my AC working before the 100 degree days started!

We had our air conditioning go out unexpectedly on a weekend. I called first thing on a Saturday morning, and a technician came out later that same morning. He was able to get the system back working in the morning, but in the afternoon we heard a sound that indicated a further problem. We called and the technician came out again that same day, was able to do some additional diagnostics and determined that a bear in the motor had gone. While Trademasters was not able to fix it that day, they called first thing Monday morning and got a technician out to replace the motor. We have a regular service agreement and they only charged us for replacing the motor. I very much appreciate the expertise and professionalism of the technicians and prompt response from the support staff. I will definitely stay with Trademasters.

Trademasters' staff worked diligently to diagnose and solve my problem. They took extra care to be sure they were pursuing the most cost effective fix, including a "second opinion" visit at no charge. The staff were pleasant and professional, and the price was fair.

TradeMaster. From the first moment Shane Allen walked into my house and game me the estimate I know I can trust them. He Diddy push me to buy he did not called me to book his service instead he gave me space for me to think about it. Few days later after I spoke with my wife we decided to move forward with TradeMaster/Shane. Do you know how horrible is that during the summer you ac broke down! That’s exactly what happened to me. But after I booked the service they came next day and reemplace my units for a new one within 7 hours. Those people now how to get the job done professionally, fast and clean. Thank you so much for your amazing services and for faster response to my emails. You guys are the best. If you need this services don’t look no further I highly recommend it.

Our experience with Trademaster was a very welcome exceptional experience in replacing our HVAC system. We had contact with five representatives/technicians for the entire process. All were most professional in presenting the information we requested to the actual installation. With the average daily temperature reaching 90 degrees, the time for replacing our system was important. From the initial request for an estimate to the installation, Trademaster folks did it in a little less than three weeks. We certainly would recommend Tademaster Services to anyone needing HVAC or plumbing service

We love Trademasters! Whether it was for planned improvements, like a new AC unit before the start of summer, or same-day repairs when the furnace died during the coldest days this winter, Trademasters has been wonderful to work with. Pricing is reasonable, with no upselling. We recommend them to everyone.

Gabriel was my technician and he was awesome. Very courteous, informative, and knowledgeable. He answered all my questions in layman's terms. The company was easy to deal with and gave me a courtesy call 10 minutes before my technician got there to let me know he was on his way. I highly recommend this company.

This week, we had our hot water heater replaced by Trademasters. We are long time clients of this company and, after pricing different providers for this installation, we decided to have them accomplish the job. Devon was our technician and I was so impressed, I sent a message to the company! Devon was not only very capable and efficient, but just such a great guy! He went way above and beyond helping me to clear the area around the hot water heater location, was kind and thoughtful and just a joy to have about for the duration of a pretty complicated job. I highly recommend Trademasters after years of dealing with this company, and I certainly recommend Devon Houston as one of their best representatives! My sincere thanks for a job well done!! ?

We had a total of 5 estimates for replacement of a heat pump and air handler for our townhouse. We found a wide range of prices, as much as $800 between them. We chose Trademasters, which was in the middle of that range, in part because they installed a furnace/ a/c in another home for us and have done fall and springs checks since then. They had always been easy to work with and schedule. That system is still working well. We had the townhouse checked out when we purchased it. David was the technician. He did a great job, explained everything about the heat pump and air handler, what potential problems we might have and the new R-ratings for coolant. The hardware was very dated (1985 and 2004), so when it had problems later, we had Trademastesr prepare an estimate. The estimator, Shane, like David, gave us cogent and detailed information and explained what he thought our best choices were. Chris (crew leader), Stephen, and Luis did the installation. They called ahead, were on time (early, even), watched out that the muddy outside did not come inside, even put up with the rambunctious puppy with grace. They worked straight through until the work was done and the house was heated, just before the unusual very cold spell that occurred in November 2019. Kudos to all of them. We would fully recommend Trademasters.
