Heating, cooling & hot water — installed and replaced right.
Whether you're replacing a worn-out boiler, upgrading to an efficient heat pump, or installing a new furnace or AC, Kanata HVAC delivers honest advice and quality workmanship to homeowners across Hamilton, Niagara, and Southwestern Ontario. Boilers and heat pumps are our specialty.
Boilers & Hydronic Heating
Few things beat the steady, draft-free warmth of a well-designed hydronic system. We install, replace and service high-efficiency boilers, radiant floor heating and hot-water (hydronics) systems for homes throughout Hamilton and the surrounding region.
If your boiler is leaking, short-cycling, or simply old and expensive to run, replacing it with a modern condensing unit can dramatically cut your heating bills while keeping every room evenly comfortable. We'll size the system properly, set up your zones, and make sure the install is clean and built to last.
- High-efficiency boiler installs & replacements
- Radiant & hydronic heating expertise
- Even, quiet, draft-free comfort
- Lower energy bills & fewer breakdowns
Most boilers last 15–20 years. If yours is near the end, we'll give you a straight comparison of repair vs. replacement — no pressure, just the smart move for your home and budget.
Heat Pumps
A heat pump is one efficient system that both heats your home in winter and cools it in summer — making it one of the smartest upgrades available to Ontario homeowners today.
Modern cold-climate heat pumps perform beautifully through Hamilton winters and can slash your energy use compared with older systems. We install, service and repair every type — air-to-water heat pumps for hydronic and in-floor heating, ducted central-air heat pumps for whole-home comfort, and ductless mini-splits for room-by-room control. Replacing an aging furnace-and-AC pair with a single heat pump (or a hybrid setup) often qualifies for valuable rebates, and we'll handle everything end to end.
- Heating & cooling in one system
- Cold-climate models for Ontario winters
- Lower carbon footprint & energy costs
- Rebate guidance included
If your furnace and AC are both aging, replacing them with a heat pump can be the most cost-effective move long term. We'll lay out the options honestly so you can decide with confidence.
Gas Furnaces
A dependable gas furnace is still the heart of heating for many Hamilton homes. We install and replace high-efficiency furnaces that keep your house warm without running up your bills.
If your furnace is more than 15 years old, struggling to keep up, or cycling on and off, a modern high-efficiency replacement pays you back in comfort and lower energy costs. We size it correctly for your home and install it cleanly so it runs reliably for years.
- High-efficiency furnace installs
- Right-sized for your home
- Reliable, even warmth
- Lower monthly heating costs
We'll tell you honestly whether a repair makes sense or whether replacement is the better value — and we'll never upsell you on capacity you don't need.
Air Conditioning
When Ontario summers hit, a properly sized air conditioner keeps your whole home cool, quiet and comfortable. We install and replace efficient central AC systems across Hamilton, Niagara Falls and beyond.
An aging AC that's noisy, weak, or using old refrigerant is costing you money every hot day. A new high-efficiency system cools better, runs quieter, and trims your summer hydro bills. We'll match the system to your home and ductwork so it performs the way it should.
- Efficient central AC installs
- Quiet, even cooling
- Right-sized for your space
- Lower summer energy bills
Replacing your furnace and AC together often saves on installation and gives you a perfectly matched system. Ask us about bundling — or about a heat pump that does both.
Water Heaters
No hot water is no fun. We install and replace tank and tankless water heaters quickly and cleanly, so your household gets back to normal fast.
If your water heater is rusting, running out too soon, or leaking, we'll help you choose the right replacement — a high-recovery tank or an endless-hot-water tankless unit — sized for how your family actually uses water. Reliable hot water, installed by people who do it right.
- Tank & tankless options
- Fast, clean replacements
- Sized to your household
- Endless hot water with tankless
Don't wait for a flooded basement. Call us and we'll get a reliable new unit in fast — with honest pricing and no upsell.
