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.

HVAC Contractor in Brockville for Stone Homes Leaving Oil Behind
Cold-climate heat pumps sized for river-town winters
Brockville HVAC jobs often start in a stone or brick house near the St. Lawrence, with an oil tank in the basement and a boiler older than anyone can remember. We replace oil furnaces and boilers with cold-climate heat pumps, using ductless or slim-duct units where new ductwork won't fit. Sizing comes from a heat-loss calculation, and your price is written and guaranteed.
- Oil furnace and boiler replacement

Heat pump installation in Brockville for homes on oil
Oil heat in an older Brockville home costs you three ways: the fill-ups, the yearly service and the tank itself, which gets harder to insure as it ages. A cold-climate heat pump takes most or all of that off your plate. It gathers heat from outside air down to -30°C, runs on electricity, and cools the house on humid river days as well.
The house is the tricky part. Stone and double-brick walls hold and lose heat differently from insulated frame walls, and many heritage homes have no ductwork at all, only radiators fed by a boiler. So we never size from square footage. We do a room-by-room heat-loss calculation, then choose how to deliver the heat: ductless heads where walls can take them, slim-duct units hidden in an attic or closet for bedrooms, or a ducted heat pump where old furnace ducts are already in place.
Many owners keep the boiler or oil furnace as backup for the first winter, then retire the tank once they trust the new system. Oil-heated homes can qualify for the higher rebate tier, up to $7,500, with pre-approval in place before installation.
- Room-by-room heat loss for masonry walls
- Ductless, slim-duct or ducted, matched to the floor plan
- 240V circuit and panel review as ESA-licensed electrical work
- We prepare and file the rebate pre-approval

HVAC services in Brockville, by the kind of house you have
Most Brockville calls are about getting off oil or making an older house comfortable year round. Start here.
St. Lawrence house problems we're asked to solve
Older homes by the river come with their own list. This is the short list we hear most along the river.
An aging oil tank sits in the basement and you'd like it gone
Once a heat pump carries the heating, the tank can go on your schedule. Some owners run the oil system as backup for one season first. Removal itself is done by a licensed fuel oil contractor.
The boiler works, but the house has no cooling at all
Radiator homes can't take central AC without new ducts. Ductless or slim-duct heat pumps add cooling for muggy summers and take over much of the heating, while the boiler stays on as backup if you want it.
The lower floor feels damp all summer
River humidity finds its way into older foundations. A properly sized heat pump pulls moisture out as it cools, and an HRV or ERV keeps fresh air moving. We size it to dry the air as well as cool it.
A neighbour swears heat pumps quit in a Brockville winter
Older heat pumps did struggle in the cold. Cold-climate models rated to -30°C are a different machine, and we size them to your home's heat loss with backup heat planned for the rare nights colder than that.
You were told central air means tearing open original plaster
That's rarely true now. Slim-duct units fit in an attic, closet or bulkhead and feed two or three rooms through short runs, and ductless heads need only a small opening for the line set.
A post-war bungalow still runs on its first oil furnace
If the ducts are in decent shape, a ducted heat pump with an electric air handler can replace the oil furnace outright. We check static pressure and duct leaks first so the new system has room to breathe.

What Brockville homeowners can expect: our customers in their own words
Rated 4.5 on Google and voted Best Company 2019, 2020 and 2021 on HomeStars.
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.

Frequently asked questions
Can a heat pump replace oil heat in a Brockville stone house?
Yes, when it's a cold-climate model sized from a room-by-room heat-loss calculation. Many owners keep the old system as backup at first, then retire the oil tank once they're comfortable.
Do I have to remove my boiler if I get a heat pump?
No. Your boiler can stay as backup heat for the coldest nights, while the heat pump handles most of the season and all of your cooling.
Is there a heat pump rebate for oil-heated homes in Brockville?
Yes. An oil-heated home can be eligible for as much as $7,500 toward a cold-climate heat pump under the Home Renovation Savings Program, with the amount set by the unit's size. Pre-approval has to come before installation.
Which suits a heritage home better, ductless or slim-duct?
It depends on the room. Ductless heads mount on a wall and suit open living areas, while slim-duct units hide out of sight and suit bedrooms where you'd rather see a small grille, and many homes use both.
Does your crew also work in Prescott and Maitland?
Yes. Our crews serve Brockville, Prescott, Maitland, Lyn and Elizabethtown, and we set install dates with you.
Who handles the electrical work for a heat pump in Brockville?
The 240V circuit and any panel work are done as ESA-licensed electrical work, and we check your panel capacity on the first visit.
