We had RP Carder Mechanical install an American Standard(Trane) furnace/air cleaner/air conditioning system in our home. We couldn’t be happier with the service we received. Ryan Carder, the owner, was knowledgeable, efficient and an all round pleasant guy to deal with. His crew, Rob and Anthony, were also just wonderful to have working in our home. They were busy from the time they arrived to the time they left. Our basement was left clean and swept, with no materials left behind. Ryan patiently answered all our questions and explained how to operate our new system. Big thumbs up to Ryan and his crew!
