Heat Pump Installation · Hamilton
Rated to -30°C, sized for the lower city or the Mountain
Heat pump installation in Hamilton starts with one question: what does your house already have? A century home on Locke Street with hot-water radiators needs a different plan than a 1960s side split on the Mountain or a ten-year-old build in Binbrook. We install cold-climate Midea and Kepler heat pumps in all three kinds of Ontario home, from $5,500, with a guaranteed quote and the rebate paperwork handled.

Every one of these comes from a real kind of Hamilton house. If your situation isn't here, our Hamilton HVAC page covers the rest of what we do in the city.
You don't need ducts. A multi-zone ductless heat pump runs up to five wall or ceiling heads off one outdoor unit, each room on its own remote. The boiler stays for the coldest stretch of January, and the heat pump carries cooling, the shoulder seasons and most of the winter.
Post-war ducts were built for a big single-stage furnace pushing slow, hot air. A heat pump moves more air at a lower temperature, so we test static pressure before we quote. Often a larger return and two or three upsized runs are enough. If not, a compact small-duct system or ductless heads are the honest answer.
One head in the attic room, one on the second floor and one on the main gives each level its own setting. No more hauling a window unit up three flights of stairs every June.
That is the cleanest hybrid case we see. A ducted EVOX G3 replaces the AC, takes over heating down to its balance point, and a new two-stage furnace or your existing one backs it up. One outdoor unit, one coil, one warranty.
Most cold-climate heat pumps need a dedicated 240V circuit. Our ESA-licensed electricians run a load calculation first. Many Hamilton homes fit the new breaker as is; some need a subpanel or a service upgrade through Alectra, and that goes in the quote, not on the final invoice.
Lake air sits under the escarpment all summer. An inverter heat pump runs long, slow cycles instead of blasting on and off, which pulls far more moisture out of the air than an oversized single-stage AC ever did.
It doesn't, it's just smaller. Enbridge gas-heated homes commonly qualify for up to $2,000 through the Home Renovation Savings Program, while homes on electric baseboards, oil or propane can get up to $7,500 based on heat pump size. We confirm eligibility before installation because program terms can change.
Outdoor units need clear airflow and some distance from the neighbour's bedroom window. We use wall brackets, raised stands and a quiet unit like the Kepler where the lot is tight, and we walk the clearances with you on the first visit.
Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.
Ducted cold-climate systems start at $5,500 installed. Ductless pricing depends on the number of heads and where the line sets run, so it is quoted per home. Either way, the number you sign is the number you pay.
| Service | Typical price in Hamilton |
|---|---|
| Cold-climate heat pump, installed Midea EVOX G3 or Kepler, 2 to 5 ton, rated to -30°C | From $5,500 |
| Ductless mini split, one zone Midea or Kepler wall unit with outdoor unit and line set | Written quote |
Installed pricing depends on size and installation requirements, and every job gets a written, guaranteed quote. Qualifying cold-climate heat pumps can bring back up to $7,500 through the Home Renovation Savings Program, and financing runs 0% for 3, 6 or 9 months on approved credit.
Four steps, and you see the price before any of the hard ones.
We measure every room, note the brick, windows, insulation and existing ducts or radiators, and run a Manual J heat-loss calculation. Mountain homes get a higher design load than lower-city homes of the same size because of the wind.
You get model numbers, size in tons, the electrical work and the installed price in writing. If you want the rebate, we file the pre-approval and wait for it before booking the install.
Licensed refrigeration technicians set the outdoor unit, run and pressure-test the line set, pull a vacuum and weigh in the charge. ESA-licensed electricians run the 240V circuit. Most single-family homes take one day; a multi-zone ductless system with four or five heads can take two.
We run heating and cooling, check the temperature split, set up the thermostat or remotes, register the warranty and file the final rebate paperwork.
Every model below is on NRCan's qualified list, which the rebate requires. We're an authorized Midea and Kepler dealer, so the warranty is factory-backed and registered in your name. For the engineering behind the -30°C rating, read our cold-climate heat pump page.

Hamilton is two climates with one postal prefix. Below the escarpment, lake air keeps winters a touch milder and summers heavier. Up top, Hamilton Mountain, Ancaster and Binbrook sit higher, catch more wind and hold snow longer. The same 1,800 square foot house can have a noticeably different heat loss depending on which side of the Jolley Cut it sits on.
That is why we don't size from square footage. We run a Manual J calculation that accounts for wall construction, window area, air leakage and the design temperature for your part of the city. From that we pick the tonnage and find the balance point, the outdoor temperature where the heat pump's output equals the house's loss. For most Hamilton homes a cold-climate unit carries the load well below -15°C on its own.
Below the balance point, backup takes over: the existing boiler in a radiator home, a gas furnace in a hybrid system, or electric strips in an air handler. We show you where that point lands for your house, so you know what the hydro and gas bills will look like, not just the purchase price.

We had a heat pump/AC unit installed by EHI, on time, on budget, great workmanship. Julian and team were knowledgeable and courteous. Dustin communicated well and is managing our government rebate for the new efficient system. Thank you Team!
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.

Cold-climate heat pump installation in Hamilton starts at $5,500 for a ducted system. Ductless systems are quoted per home based on the number of indoor heads. Installed pricing depends on size and installation requirements, and you get a guaranteed written quote before any work starts.
Yes. A multi-zone ductless heat pump heats and cools a radiator home with no ductwork, and the boiler stays as backup for the coldest nights. Cold-climate heads keep producing heat down to -30°C.
A gas-heated home commonly qualifies for up to $2,000 through the Home Renovation Savings Program, while electric, oil, propane or wood-heated homes can receive up to $7,500 based on size. Pre-approval must be in place before installation and program terms can change, so we confirm eligibility first. Financing runs 0% for 3, 6 or 9 months on approved credit, and the rebate comes back on top of that.
Most ducted and single-zone ductless installations take one working day. A multi-zone system with four or five heads often takes two. We give you the booking date once the quote is signed and, if you're using the rebate, once pre-approval comes back.
Not always. Many Hamilton homes on a 100 amp service have room for the dedicated 240V circuit. Our ESA-licensed electrician runs a load calculation during the quote visit, and if a panel change or a service upgrade through Alectra is needed, it goes in the written price.
Yes, when it's sized from a heat-loss calculation for that part of the city. Midea EVOX G3 and Kepler units are rated to operate at -30°C, and we pair them with a furnace, boiler or electric backup for the few nights that go past the balance point.
