Lower winter bills without the sales pitch
If your Cornwall HVAC question is really a money question, you're in the right place. Plenty of homes here heat with electric baseboards, and a cold-climate heat pump can take a real bite out of that winter bill. We explain the rebate in plain terms, give you a guaranteed price, and keep gas furnaces running safely for homes that aren't ready to switch.

Cornwall homes have their own mix of heat sources and costs. These shape every plan we put on paper.
Electric-heated homes feel every rate change. We use your actual bills to estimate what a heat pump would save, not a national average.
Gas-heated homes can still add a heat pump for cooling and mild-weather heat, with the furnace kept as backup.
St. Lawrence summers are sticky and Eastern Ontario winters bite. A heat pump covers both seasons with one outdoor unit.
Cornwall is a bilingual city, and the paperwork should be easy for everyone at the kitchen table. Bring a family member to the visit, or have them read the quote with you.
Most calls here come down to cost or reliability. Here's what we see and what we do about it.
Every kilowatt a baseboard draws comes out as one kilowatt of heat, never more. A cold-climate heat pump moves heat in from outdoors instead, so it uses much less power for the same warmth through most of the winter. Electric-heated homes also sit in the higher rebate tier, up to $7,500.
We walk through it line by line: the heat pump size, the amount that size can qualify for, and the pre-approval that has to happen before installation. If a number depends on program terms, we tell you, because those terms can change.
Old baseboards in drafty rooms fight a losing battle. A multi-zone ductless system puts a head in each main area, and we look for big air leaks before sizing so you don't pay for capacity you won't use.
Dirty flame sensors, failing pressure switches and blocked vents are the usual suspects. Our TSSA-certified gas technicians find the real fault, quote the repair before starting and tell you honestly if the furnace is near the end.
A ductless heat pump cools quietly in summer and heats in winter. In a baseboard home, that one install retires the window units and takes over most of the baseboard load.
Between the rebate for eligible homes, 0% financing for 3, 6 or 9 months and open loans from 2.99% OAC, many households can spread the cost. We lay out each option side by side so you can compare.
An electric furnace is a bank of heating strips in a cabinet, and it costs about the same to run as baseboards. The good news is the ducts are already there. A cold-climate heat pump with a Midea electric air handler drops onto the same ductwork, the strips become backup for the coldest nights, and the home still qualifies for the electric-heat rebate tier.
Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.
You should be able to read the price table as easily as the quote. Starting points are below, in plain dollars, and the rebate comes off after the install.

Pick the job closest to yours. Each page covers what's involved and what tends to drive the cost.
No jargon, no rush, and the numbers in writing.

We measure rooms, look at windows and insulation, check the panel for a 240V circuit and plan where the heads and outdoor unit can go.

We submit the pre-approval before anything else. Then our licensed crew installs and tests the system and shows everyone in the house how to use the controls.
For an electric-heated home, the heat pumps and ductless units matter most. For a gas home keeping its furnace, the two-stage models below are the ones we install and service.

The rebate isn't a discount at the till. It's a payment that comes to you after the install, and the amount depends on the size of the heat pump and how the home was heated before. Here's how we show it so there are no surprises.
Electric-heated homes in the East End, Riverdale and Le Village sit in the higher tier, up to $7,500. Enbridge gas homes commonly see up to $2,000. Pre-approval has to be in place before the install, program terms can change, and we say so on the quote in plain words.

Your quote is your final price. No surprise extras on the agreed scope of work.
Cold-climate heat pumps may qualify through the Home Renovation Savings Program. We confirm eligibility and file the paperwork.
Interest-free for 3, 6 or 9 months, or open loans from 2.99% on approved credit.

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.
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.
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!
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.
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.
