Most straightforward replacements are done in one day. New installs or jobs that need extra ductwork or venting can take longer — we'll tell you in your quote.

It depends on your home's heat loss — insulation, windows, square footage and air leakage — not just the size of the old unit. We calculate it during the free visit.

If your air conditioner is more than about 10–12 years old, replacing both together often makes sense because the indoor coil and blower are matched. We'll quote both options.

Ontario's current Home Renovation Savings rebates focus on heat pumps, thermostats and insulation. A hybrid system (furnace + cold-climate heat pump) may qualify — ask us.

A heat pump cools exactly like an AC and also heats your home efficiently in spring, fall and much of the winter. With Ontario rebates for cold-climate heat pumps, many homeowners now choose one instead of a plain AC.

Higher SEER2 means lower running costs. Two-stage and variable-speed models are also quieter and better at removing humidity. We'll show you the difference in your quote.

Yes — a ductless mini-split is the usual answer for homes with radiators or baseboard heat.

Cold-climate models keep heating at very low temperatures — for example, the TOSOT APEX is rated to heat down to −30 °C. Many homes also keep a gas furnace as backup for the coldest days.

Ontario's Home Renovation Savings Program lists up to $7,500 for a cold-climate air-source heat pump, depending on size and eligibility. Programs change, so we confirm what's open when we quote.

Usually, yes. We check your duct sizes and airflow during the visit.

A heat pump plus a gas furnace. The heat pump does most of the work; the furnace takes over on the coldest days. It's a popular, efficient choice in the GTA.

Usually, yes. Rental contracts have buyout terms; we can help you understand the process and handle the removal and return of the rental tank.

Sometimes. Tankless units use a lot of gas for short periods, so we check the line size and meter during the visit.

With regular descaling, a quality tankless unit typically lasts longer than a tank. Check each brand's warranty — some heat exchangers are covered for 15 years or more.

One appliance — usually a tankless water heater — provides domestic hot water and heats water for the air handler, which warms the air in your ducts.

Yes. Most AirMax units take a DX cooling coil connected to an outdoor condenser or heat pump.

Yes — tell us the brand and model when you book.

Leave the home right away and call your gas utility's emergency line (Enbridge Gas in most of the GTA) or 911 from outside. Don't use switches or phones inside.

We service most residential brands of furnaces, ACs, heat pumps and water heaters.

If it's over 15 years old and needs a major part like a heat exchanger or control board, replacement is often better value. We'll give you both prices.

A tank costs less up front; tankless gives endless hot water and saves space. We'll quote both.

Yes, we can remove it and help you arrange the return.

Insulation makes any heater work far better. We can size for an uninsulated space, but it will need a larger heater.

Gas is usually cheaper to run in larger or uninsulated spaces; electric is simpler for small, well-insulated garages.

Yes — we can extend supplies and returns from your existing system, or recommend a separate zone.

Leaky ducts lose heated and cooled air into walls and ceilings. Sealing the accessible joints usually improves comfort and airflow.

Lower than in summer — usually around 30–40%, and lower on very cold days so windows don't fog up. A modern control adjusts this automatically.

Ontario's Home Renovation Savings Program lists a smart thermostat rebate of up to $100 for eligible models. We confirm when we quote.

Yes — call 905-667-2823 any time.

Homes with high winter humidity usually suit an HRV; homes that get too dry often suit an ERV. We'll check during the visit.

Typically every few months — more often if you have pets or renovation dust.

Yes — ductless mini-splits or a high-velocity system are common options.

A thick media filter in a proper cabinet usually filters better with less restriction than a thin high-rated filter. We check airflow after installing.

Furnaces in early fall, air conditioners in spring — but any time is better than never.

Yes — tell us how many units you have and we'll propose a schedule.

Yes, we can schedule around your business hours.

Yes, our licensed gas technicians install and modify gas lines for heaters and equipment.
