HVAC Services in Belleville, Ontario
Johnston Mechanical HVAC LTD serves Belleville and the surrounding Hastings County area. Brandon Johnston — TSSA certified gas technician (FS-R-52252) — personally oversees most jobs in Belleville, from furnace replacements to full new-home HVAC rough-ins.
Serving Belleville and Hastings County
Belleville is approximately 20 minutes west of our Trenton base along Highway 2 and the 401. It is one of our most active service areas — we schedule Belleville jobs regularly and can typically respond within one to two business days for non-emergency work, and same-day for heating emergencies when our schedule allows.
Belleville's housing stock ranges from older downtown homes with original ductwork to newer subdivisions in the east and west ends that need cold-climate heat pump systems. Brandon has worked across all of it. He visits the site before quoting, sizes equipment to the actual home, and is on the job himself — not sending a crew.
Every installation comes with a written quote, no surprises on the invoice, and a 5-year labour warranty as standard. A 10-year labour warranty upgrade is available at the time of installation. Brandon is TSSA certified (FS-R-52252), and all gas work is done to code.
Belleville homeowners looking for furnace installation, AC, heat pumps, HRV ventilation, tankless water heaters, or new-home HVAC rough-in can reach Brandon directly at (613) 827-8973 or by email at contact@johnstonmechanical.ca.

HVAC in Belleville: What to Know
Belleville experiences the same Lake Ontario-influenced climate as the rest of the Quinte region — cold winters, humid summers, and rapid shoulder-season swings. A properly sized and commissioned system handles all of it without short-cycling or running constantly.
Belleville has a wide range of housing stock. Older homes in the downtown core and west end often have original ductwork that was sized for lower-efficiency equipment. When replacing a furnace or adding central AC, Brandon checks duct sizing and static pressure before recommending equipment. Installing a high-efficiency furnace in an undersized duct system creates noise, uneven heating, and premature heat exchanger failure.
Belleville's newer east-end and north-end subdivisions are well-suited for cold-climate heat pumps. The TOSOT Apex Ultra Heat operates efficiently down to -30 degrees Celsius, making it a practical primary heating source for Belleville winters when paired with a backup furnace or electric resistance element. Brandon can assess whether a heat pump makes sense for your home during the site visit.
Belleville also has a significant number of multi-unit residential and light commercial properties. Brandon handles residential work only — single-family homes, townhomes, and small multi-unit buildings. For larger commercial scopes, he will tell you upfront if the job is outside his scope rather than taking it on and underdelivering.
