Our team of professional HVAC technicians is ready to diagnose and resolve any heating system issue. We service all makes and models, including Carrier, Lennox, Trane, Ruud, and York.
Heating Repair
When your heating stops working, you need more than a quick fix and a guess. Our technicians service any make or model and diagnose the actual issue - whether it's a faulty ignitor, a failing blower motor, a cracked heat exchanger, or a thermostat communication problem. That means your system doesn't just blow warm air - it runs safely and efficiently, so your home stays genuinely comfortable.
Many repairs address symptoms without finding the underlying cause. We take the time to inspect and verify, so the fix lasts and your energy bills stay low.


Heating Replacement
A new furnace is a significant investment, and sizing it correctly makes all the difference. We perform proper heat loss calculations to determine the exact capacity your home needs - not a guess based on square footage alone or a like-for-like swap of the old unit.
Here's what most contractors won't tell you: oversizing is the most common mistake in furnace replacement. An oversized system short-cycles, doesn't run long enough to reach peak efficiency, and wears out components faster. We size your new furnace to your home's real heat loss so you get even heat and efficient runtime - not just a bigger furnace that costs more to run.
Heating Maintenance
Your furnace works hard through Ontario's cold winters. Annual maintenance keeps it running efficiently, prevents costly breakdowns, and extends the life of your equipment. A well-maintained system uses less energy, heats more evenly, and runs safely - year after year.
Our tune-up includes heat exchanger inspection, burner and ignitor cleaning, bl motor and bearing check, venting and safety control testing, and a full system performance assessment. And when you combine your furnace maintenance with an AC maintenance plan, you get a bundled discount - year-round protection for less.

Frequently Asked Questions
If your system is over 15-20 years old, needs frequent repairs, or isn't keeping up on cold days, it may be time to consider replacement. We'll assess your system honestly and help you weigh the options.
High-efficiency furnaces convert more of their fuel into heat for your home, reducing energy waste and lowering utility bills. We'll explain the options and help you decide if the upgrade makes sense for your situation.
We perform proper heat loss calculations based on your home's insulation, windows, square footage, and climate zone. This determines the exact heating capacity you need - not a guess or a like-for-like swap of your old unit.
