Hey everyone, Russell here from Greenfoot Energy Solutions. I'm standing outside a home that, like a lot of houses across the Maritimes, was built around electric baseboards. The homeowner is tired of getting walloped every winter by their power bill, so today we're swapping out the system doing the most damage to that bill. We're installing a ductless mini-split heat pump. In this post, I want to walk you through why baseboard-to-heat-pump is one of the highest-return upgrades a Canadian homeowner can make, and exactly what happens when our crew shows up to put one in.
Why Are So Many Canadian Homes Still Heated with Electric Baseboards?
Across Atlantic Canada, BC, and large parts of Quebec and Ontario, electric baseboard heat is everywhere. Statistics Canada data on household energy use shows that roughly four in ten Canadian dwellings still rely on electric resistance heating as their primary source. Builders have leaned on it for decades because the upfront cost is low: cheap wire, cheap heaters, no ductwork, no chimney. But cheap to install does not mean cheap to run, and that math has only gotten worse as electricity prices have climbed.
Baseboard heat works by converting electricity into heat at a one-to-one ratio. Every kilowatt-hour you pay for puts about one kilowatt-hour of heat into your home. That is the ceiling. There is no way to make a resistance heater more efficient, because the heater is already doing the most it can do. The bill just reflects the physics.
How Much More Efficient Is a Mini-Split Heat Pump Than Baseboard Heat?
A modern cold-climate ductless mini-split does not generate heat by burning electricity. It moves heat from the outside air into your home using a refrigeration cycle. Even at -25°C, the outside air still holds usable heat energy, and the heat pump simply concentrates it and pumps it indoors.
The result is what is called a Coefficient of Performance, or COP. A good cold-climate mini-split running in mild Maritime weather will deliver a COP of 3 to 4, which means for every kilowatt-hour of electricity you put in, you get three to four kilowatt-hours of heat out. Even in deep cold, where COP drops, you are still well ahead of baseboard. Compared to electric resistance, an ENERGY STAR certified cold-climate heat pump can cut your heating cost by 50 to 60 percent over a Canadian winter. That is not a marketing line, that is what the Natural Resources Canada heating and cooling guidance shows.
And here is the part baseboard cannot do at any price: in summer, that same mini-split runs the cycle in reverse and gives you air conditioning. One system, two seasons, one bill.
What Actually Happens on Mini-Split Install Day?
This is where the video at the top picks up. Our crew is built from two trades working side by side: a refrigeration technician and a licensed electrician. That pairing matters, because a heat pump install is half refrigerant work and half electrical work, and you do not want either side getting handed off to someone who is improvising.
Here is the sequence we follow on a typical single-head residential install:
- Walk-through and placement. The technician confirms where the indoor head and outdoor unit will live, based on airflow patterns through the house, the homeowner's furniture layout, and required clearances around the outdoor unit.
- Mount the wall bracket. The indoor head gets a bracket fastened to the wall studs, with very specific levelling so the condensate drain line will run downhill on its own, without a pump.
- Core drill. A small hole (typically 2.5 to 3 inches) goes through the exterior wall behind the indoor head. This is the single penetration that carries the refrigerant lines, the condensate drain, and the low-voltage communication cable from inside to outside.
- Outdoor unit set. The compressor (the box that sits outside) gets mounted on aluminum stands. We either bolt those stands to the foundation wall or secure them to a patio stone, depending on the site.
- Line set and electrical. The refrigerant lines, drain, and communication cable get run between the two units, then dressed with a slim white line-set cover for a clean exterior look. The electrician brings a dedicated circuit in from your panel and ties the outdoor unit through a disconnect switch.
- Vacuum, charge, and commission. Before the system gets refrigerant, we pull a deep vacuum on the line set, hold it, and check for leaks. Then we release the factory refrigerant charge, power the system on, and run it in both heating and cooling to confirm it is operating correctly. All of this is done to the refrigerant handling standards published by the CSA Group.
- Homeowner walkthrough. The last thing we do is sit down with the homeowner and show them the remote, the app if their system has one, how to clean the filters, and what the basic seasonal maintenance looks like.
How Long Does a Ductless Mini-Split Installation Take?
A standard single-head install runs about five to six hours from arrival to walk-through. Multi-zone systems (one outdoor unit feeding two, three, or four indoor heads) usually take a full day, and occasionally two if the line-set runs are long or the wall penetrations are difficult. The actual disruption inside your home is minimal. Most of the work happens outside, and homeowners normally stay in the house while we install.
What Does a Mini-Split Heat Pump Cost in Canada After Rebates?
Before rebates, a professionally installed single-head ductless mini-split in Canada typically lands somewhere between $4,500 and $7,500, depending on capacity, brand, and complexity of the install. Multi-zone systems scale up from there.
The rebate picture is where things get interesting. Every province we operate in (New Brunswick, Nova Scotia, PEI, Newfoundland and Labrador, and British Columbia) has its own utility or efficiency program offering meaningful rebates on heat pump installs, and several of them stack with federal incentives. The amounts and program names change often, so rather than list numbers that will be out of date next month, we maintain a live page that pulls all of the current Canadian heat pump and home energy rebates into one place. See our Canadian heat pump and home energy rebates hub for what is actually available in your province this season.
For the federal government's own breakdown of how heat pumps work in a Canadian climate, the NRCan Heating and Cooling with a Heat Pump booklet is the single best plain-English reference, and it is free.
Is a Ductless Mini-Split the Right Fit for Your Home?
If your home is on electric baseboards, oil, or propane, the answer is almost always yes. The payback math, once you stack the rebate against the difference between what you pay now and what a heat pump will cost to run, usually lands somewhere between three and seven years for most Maritime homeowners. After that, the system is paying you back every month until it is retired (typical service life is 15 to 20 years with annual maintenance).
Homes that already have central forced-air ductwork may be a better fit for a centrally ducted heat pump instead of a ductless mini-split. And older homes with poor insulation may benefit from doing some envelope work first, so the heat pump you buy can be sized correctly and not oversized to compensate for losses.
