Your heating and cooling system is one of the most significant investments in your home. Like any complex mechanical system, HVAC maintenance is crucial for the longevity of your unit. Without regular professional care, your HVAC equipment will break down more frequently, operate less efficiently, and cost you substantially more in energy bills and emergency repairs.
At Unionville Heating & Air Conditioning, we’ve been serving the Markham and Stouffville communities since 1985. Our experience has shown that homeowners with maintenance plans enjoy longer-lasting equipment, lower utility bills, and fewer emergency service calls than those who skip regular maintenance.
Our comprehensive HVAC Maintenance Protection Plan offers exceptional value and complete coverage for your home comfort systems. When you invest in our maintenance plan, you’re not just paying for service visits—you’re investing in protection, priority treatment, and significant long-term savings.
Our certified TSSA Gas Technicians perform a comprehensive 21-point inspection and service of your cooling system, including:

Our maintenance plan members experience tangible benefits that make a real difference in their homes and finances:
Our service records show that homeowners with our maintenance plan have average energy savings of 15-25% compared to those without regular maintenance. On a typical Markham home with $2,400 annual HVAC energy costs, that’s a savings of $360-$600 per year.
The average HVAC system lasts 12-15 years. Our maintenance plan customers regularly see their systems perform reliably for 17-22 years—a significant extension that saves thousands in replacement costs.
In 2024, our maintenance plan customers experienced 78% fewer emergency service calls than non-plan customers. The average emergency repair costs $450-$700, making prevention through maintenance a smart financial decision.

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.
You guys are simply the best. You are always there when we have an item that needs to be looked and always offer trustworthy advice and insight. Technicians are very professional and polite.
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.
