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.
