Heating and cooling in King City homes off the gas line
Out on the Oak Ridges Moraine, the wind has nothing to slow it down and winter nights run colder than in the city to the south. Plenty of properties around King City, Kettleby and Pottageville were never connected to natural gas, so they heat with propane, oil or electric baseboards.
Those are the homes where a cold-climate heat pump pays off fastest. Units like the Midea EVOX G3 are rated to heat down to -30°C and keep strong capacity at -15°C. Homes heated by propane, oil, electricity or wood can qualify for the higher rebate tier of up to $7,500 through the Home Renovation Savings Program, as long as pre-approval is in place before installation.
We never pull out the old system without a plan for the coldest nights. Most rural installs keep a backup, either the existing propane or oil furnace in a hybrid setup, or electric heat strips inside a new air handler.
- Manual J sizing that accounts for open, windy exposure
- Outdoor units raised above the drifts on stands or wall brackets
- 240V circuits and panel upgrades by ESA-licensed electricians
- Rebate pre-approval filed before install day

Problems we solve on King Township estates and farms
Large homes and rural lots bring their own set of calls.
Filling the propane tank feels like a second mortgage
Propane prices move with the market, and a large house burns through a lot of it. A cold-climate heat pump can take over most of the heating, leaving the propane furnace for the coldest stretches.
One wing of the house never matches the other
Big homes with separate wings or a walkout lower level rarely do well on one system. A multi-zone ductless setup or a second ducted system gives each part of the house its own control.
A winter power outage leaves the house cold
A heat pump draws a lot of power, so it may not run on a small generator. We plan backup heat around the generator you have, often a propane furnace whose blower needs far less power, and tell your electrician what load to allow for.
Drifting snow buries the outdoor unit
Open fields mean big drifts. We mount outdoor units on stands or wall brackets above the usual snow line and keep them out of the main wind path, so defrost works and airflow stays clear.
The oil furnace is old and the tank is due for replacement
Instead of paying for a new tank for a fuel you'd rather leave, many owners switch to a heat pump with an electric air handler. Homes leaving oil often qualify for the higher rebate tier.
The office over the garage freezes in January
A single-zone ductless heat pump heats and cools a garage suite or guest house without running ducts or gas, and it works on its own thermostat.

Replaces our AC with a new heat pump in Ottawa and the whole experience was outstanding. From the first call, Dustin was incredibly responsive and communicated clearly every step of the way. He cut through all the usual sales fluff and got straight to what mattered — options, costs, timelines, and what made the most sense for our home. They addressed every concern I had, explained the details discussed my technical questions, and handled the installation quickly and professionally. The quality of the work is excellent, everything was done cleanly, and the system has been running perfectly since. Pricing was fair and transparent, and there were no surprises. It’s rare to find a company that combines speed, honesty, and solid workmanship like this. Highly recommended.
Recently got a shiny new heat pump installed. Went very well, nice unit and it works soooo quietly. These fine folks were very easy to deal with, professional and thourough. Would highly recommend.
Efficient Home Improvements truly went above and beyond. Our furnace failed on Christmas Eve in Ottawa, and their team stayed up late (3:00am) that night to replace it. Their responsiveness, professionalism, and dedication during the holidays were exceptional. The work was completed efficiently, and everything was explained clearly. It’s rare to find a company willing to sacrifice their own holiday time to ensure a customer’s home is warm and safe. I highly recommend Efficient Home improvements to anyone in need of reliable and compassionate service.
I recently had a new furnace and tankless water heater installed by this company. Excellent service by both office and technicians , I highly recommend!
The Installers were great.. Got in and got the job done..the furnace works amazing compared to the old one !!! Need a furnace..A/C water tankless system..there your guys!!!!
Had a tankless water heater installed and couldn’t be happier. The installation was quick, professional, and the system works great — endless hot water and more efficient than my old tank. Highly recommend!
Dustin and his team were really responsive and helpful in getting us a new heat pump to replace our broken AC unit. The team went above and beyond helping us through the process and answering other questions about the house we recently moved in to. I would highly recommend Efficient Home Improvements for any of your HVAC needs.

Frequently asked questions
Can a heat pump heat a large King City home in January?
Yes, when it's sized from a heat-loss calculation that accounts for wind exposure. Cold-climate units are rated to -30°C, and we add backup heat for the coldest nights.
Will my heat pump run on a generator during a power outage?
Only if the generator can handle the heat pump's starting and running load, which many portable units can't. We often keep a propane furnace or plan a smaller backup load so the house stays warm on generator power.
How much is the heat pump rebate for a King City home on propane?
Homes heated by propane, oil, electricity or wood can qualify for up to $7,500, based on heat pump size, through the Home Renovation Savings Program. We file the paperwork, and pre-approval has to be in hand before installation.
Is multi-zone ductless a good fit for an estate home?
Often, yes. One or more outdoor units can feed separate wings, a guest house or rooms the ducts don't reach, each with its own control.
Do your HVAC services in King City reach Nobleton and Schomberg?
Yes. We serve King City, Nobleton, Schomberg, Kettleby and the rest of King Township.
Who handles emergency HVAC in King City on weekends?
We do. Our technicians answer emergency calls on evenings, weekends and holidays. Call 1-647-694-5845 and we'll tell you when a technician can get out to you.
