Technician arrived right on time and did a thorough job of doing the maintenance service. He was pleasant and courteous and remembered coming last year. Gave honest opinion of the longevity expectation for my old furnace.

Best experience we have ever had with an HVAC company. We suffered dealing with Enercare until we contacted Unionville. Night and day difference. Unionville HVAC is owner-operated. It means that John makes sure everyone who works for him is qualified and professional. Feel 100% confident in calling John and his people. They are honest and decent people who still believe in customer satisfaction. I’ll never use anyone else.
On short notice, Unionville H&A provided service and support to address and replace broken thermostat, swap out air and humidifier filters and service and clean our furnace. The timely manner in which they responded was impressive and appreciated.
