HVAC in Waterloo: Heating and Cooling From Your Neighbours

We look after residential heating and cooling in Waterloo, from a furnace that quit overnight to a full heat pump install. Everything is done by licensed gas technicians, and we install Lennox and York equipment.

• Heating: furnace repair in Waterloo, furnace installation and replacement, and heat pump installation for homes that want to heat with less gas, plus heat pump repair and maintenance.
• Cooling: AC repair in Waterloo, central air installation and ductless mini-splits for additions, attic rooms and homes without ducts.
• Everything else: tank and tankless water heaters, gas lines for BBQs, ranges and fireplaces, and seasonal tune-ups.

We don't do duct cleaning, boilers or commercial work. If that's what you need, we'll tell you up front.

Waterloo's housing falls into a few eras, and each one tends to have its own HVAC problems. Knowing which one you live in tells us a lot before we open the furnace door.

Uptown and the older core. Homes near Uptown Waterloo and the streets around the old town centre include pre-war houses with ductwork that was added or rebuilt over decades. Expect undersized returns, rooms that never quite heat, and old chimneys that no longer suit modern equipment. A new high-efficiency furnace vents through plastic pipe out the side wall, which can leave a gas water heater alone in an oversized chimney that needs a liner.

1960s and 70s neighbourhoods. Beechwood started with a handful of homes in the late 1950s and grew mostly in the 1970s. Lakeshore and the streets around the universities are from the same broad period. Many of these homes are on their second or third furnace, and the ductwork was sized for equipment that ran very differently. Bungalows and backsplits here often have one floor that's too hot and one that's too cold.

1990s to 2010s subdivisions. Laurelwood, Columbia Forest, Clair Hills and the newer parts of Eastbridge were built with builder-grade furnaces and AC units. A lot of that original equipment is now 15 to 25 years old, which is when inducer motors, control boards and heat exchangers start to fail. If you bought new in one of these areas and never replaced anything, it's worth planning before a January breakdown forces the decision.

Rentals near the universities. Northdale and the streets around the University of Waterloo and Laurier have many converted houses. Landlords there usually want reliable, fast repairs and straight answers on repair-versus-replace.

Natural gas in Waterloo is delivered by Enbridge Gas, and electricity by Enova Power (formed when Waterloo North Hydro merged with Kitchener-Wilmot Hydro). That matters because Ontario's main home efficiency rebates run through those utilities.

The Home Renovation Savings Program, delivered by Save on Energy and Enbridge Gas, offers rebates of up to several thousand dollars on qualifying cold-climate heat pumps, plus smaller rebates on items like smart thermostats. Amounts depend on the equipment and how your home is heated now, and the program's rules change, so check current eligibility before you buy. Our Ontario heat pump rebate guide walks through the steps.

Rebates rarely cover a standard gas furnace on its own, so don't expect a furnace replacement to come with a cheque.

Waterloo Region's heating systems are sized for a winter design temperature of around -19°C to -20°C, and our summers regularly bring humid stretches in the 30s. That range is why equipment sizing matters here.

An oversized furnace short-cycles, wears out its parts early and leaves the house drafty. An oversized AC cools the air before it can pull out humidity, so the house feels clammy. We size to your home, its existing system and how it's been performing, not just to whatever was there before.

If you're weighing a heat pump, today's cold-climate units keep heating well below -20°C, and many Waterloo homes pair one with a gas furnace as backup (a dual-fuel setup). Our heat pump vs furnace guide covers the trade-offs for this climate.

If your furnace is under about 15 years old and one part has failed, repair it. If it's near 20, needs a major part and has needed other repairs lately, start planning a replacement. The same logic applies to air conditioners, with one extra flag: an older AC that runs on R-22 refrigerant and starts leaking is rarely worth recharging.

Our furnace replacement cost guide shows typical regional price ranges, so you know roughly what you're weighing before anyone quotes.

If your furnace stops in the middle of the night, call 519-498-4710. A person or our after-hours receptionist takes your details, and we'll get back to you to book the visit.

Before you call, check the obvious: thermostat batteries and setting, the furnace power switch, the breaker, and a clogged filter. If you smell gas, leave the house and call Enbridge Gas from outside. If a technician from another company has red-tagged your furnace, read our red tag guide first so you know your options.

We also serve the rest of the region, including Kitchener, and the townships listed on our service area page.
