From Woodbridge to Kleinburg, Maple to Thornhill — Megacity HVAC provides Vaughan homeowners with expert heating, cooling, and air quality services. Our licensed technicians specialize in high-efficiency furnace installations, central air conditioning, heat pump systems, and whole-home air purification. As an Enbridge Sustain partner, we help you save on every upgrade. Vaughan has experienced massive residential growth over the past two decades, with sprawling subdivisions in Vellore and Maple alongside established Italian-Canadian communities in Woodbridge and rural estate properties in Kleinburg. Our team handles the full range — from standard suburban furnace swaps to complex multi-zone systems for Kleinburg's 5,000+ square foot estate homes.
Vaughan's housing stock is largely post-1990s suburban construction, with many homes in Maple and Vellore built between 2000 and 2015. These homes typically have builder-grade 80% efficiency furnaces and 13-SEER AC units that are now 15–25 years old and due for replacement. Woodbridge's older core features 1970s–80s backsplits and side-splits, while Kleinburg has large rural estate homes on acreage that often require multiple HVAC zones, humidification systems, and backup heating due to their size and exposure. Many Vaughan homes also have finished basements with inadequate heating that benefit from supplemental ductless units.
Vaughan's position north of Toronto makes it one of the colder GTA municipalities, with Kleinburg and rural areas regularly hitting -25°C on the coldest winter nights. The large open lots in newer Vaughan subdivisions offer little wind protection, meaning furnaces work harder and homes benefit significantly from upgrading to variable-speed, modulating furnace technology that adjusts output to match demand.

All specifications are published by the manufacturer. We install and service these systems across Toronto & the GTA.
Describe the issue. We dispatch a technician with common parts already on board.
We test refrigerant pressure, electrical connections, heat exchangers, and airflow — finding the root cause, not just the symptom.
A clear explanation and a fixed price. You approve before any work starts.
We fix or install, run a complete system cycle, confirm temperatures, and clean up before leaving.
Most are resolved same-day with parts we carry on our trucks.
Faulty ignitor, tripped limit switch, failed inducer motor, or cracked heat exchanger — common winter calls we resolve same day.
Low refrigerant, dirty condenser coils, or a failing compressor. We carry refrigerant and the most common parts on every truck.
The system turns on and off without completing a cycle — usually a clogged filter, low refrigerant, or an oversized unit.
Grinding, squealing, or rattling from any HVAC unit. Often a failing blower motor, loose hardware, or compressor wear.
Clogged condensate drains, frozen evaporator coils, or a cracked secondary heat exchanger. High humidity makes drain clogs frequent.
Hot rooms upstairs, cold rooms in the basement — often caused by ductwork imbalance, blower issues, or an undersized system.
Authorized Lennox Dealer — and fully equipped to install, repair, and maintain every major HVAC brand sold in Ontario.












As a certified Enbridge Sustain Trusted Partner, we offer Vaughan homeowners a new furnace, AC, heat pump, or water heater with nothing down. Standard ACs and furnaces are not covered by current rebate programs, but the Sustain lease-to-own program keeps the upfront cost at $0.
