Gravenhurst HVAC for Cottages Becoming Year-Round Homes
From May-to-October cottage to a home you can live in all year
Plenty of HVAC work in Gravenhurst begins with the same plan: the cottage on Lake Muskoka or Gull Lake is about to become a full-time home. That means real winter heat, a way off propane and baseboards, and a plan for the weeks the place still sits empty. We do all three with ductless and ducted cold-climate heat pumps, sized for Muskoka cold and backed by a price you get in writing.
- Ductless heat pumps that heat the whole cottage, no ducts needed
- A path off propane and baseboards, with the old heat kept as backup
- Outdoor units mounted to suit rock, slopes and deep snow
- Up to $7,500 in rebates for electrically or propane-heated homes

Heat pump installation in Gravenhurst: is the cottage ready?
Before we size a single unit, we walk through the building with you. A cottage built for summer often needs a few things sorted before any heat source can keep up with a Muskoka winter.
- Insulation in the walls, attic and under the floor, especially over an open crawlspace
- Skirting or a sealed crawlspace so cold air isn't blowing under the floor
- Electrical service with room for a heat pump's 240V circuit, or a panel upgrade planned in
- A spot for the outdoor unit that's off the rock, above the snow and away from the roof's drip line
- A winter route to the door, so service visits are possible when the road is snowed in
- Water lines protected where they enter the building
- Your current propane furnace, wood stove or baseboards checked for use as backup heat
- A list of the rooms you'll live in most, so heat goes where you spend your time
Getting a Gravenhurst cottage off propane and baseboards
Most Gravenhurst cottages were heated for shoulder seasons, if at all. A propane wall furnace in the main room, a few baseboards in the bedrooms, maybe a wood stove. That's fine for Thanksgiving. It's expensive and patchy for a full winter.
A cold-climate heat pump changes the math. It pulls heat from outdoor air even in deep cold and moves it inside, so it delivers far more heat than a baseboard for the same hydro. Going ductless means each indoor head connects through one small wall opening, a good match for cottages on piers or slabs with nowhere to hide ducts.
We usually keep the propane unit or baseboards in place as backup. That matters most when the house still sits empty for a few weeks. If the heat pump stops, the backup holds the line, and a connected thermostat lets you see it happen from the city.
- Higher rebate tier for homes heated by propane, electricity, oil or wood
- Indoor heads sized room by room from a heat-loss calculation
- Backup heat left in place for the coldest nights and the empty weeks

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 ductless heat pump be the main heat for a Gravenhurst cottage?
Yes, in a cottage that's insulated for winter and sized from a heat-loss calculation. We keep a backup source in place for the coldest nights and for any stretch when nobody's there to notice a problem.
Do I need to insulate the cottage before installing a heat pump?
Usually some, yes. A cottage with an open crawlspace or thin walls loses heat faster than any reasonable system can replace it, so we point out the upgrades that matter most before we size the equipment.
How much rebate can a propane-heated cottage in Muskoka get?
A cottage heated by propane falls in the higher bracket of the Home Renovation Savings Program, worth up to $7,500 depending on heat pump size. Confirm eligibility before installation, as the rules can change.
What keeps the pipes safe if the heat pump stops while I'm away?
Backup heat and an alert. We leave your propane unit or baseboards ready to take over, and a Wi-Fi thermostat can warn you when the indoor temperature drops.
My Gravenhurst lot is mostly rock. Where can the outdoor unit sit?
Wherever it can sit high, drain well and dodge the roof's snow load. On Shield rock that usually means pinning a stand to the granite or hanging the unit on the wall, and we choose the spot together on the site visit.
Are you an HVAC company in Gravenhurst?
Not in town. We work out of Stouffville, and Gravenhurst and the lakes nearby are part of our regular service area, with visits and installs set up in advance around your plans.
