Heat Pump Installation in Oshawa on the Ducts Your House Already Has
Old brick, old ducts, new heat pump. It works when the airflow is measured first.
Heat pump installation in Oshawa is mostly a question about ductwork. The brick homes near downtown and the post-war bungalows around them have supply runs sized for a furnace from another era, and a heat pump needs more air per ton than that furnace ever did. We measure before we size, pair the heat pump with your gas furnace where that makes sense, and handle the rebate paperwork for homes across Durham Region and Ontario.
- Static pressure and airflow tested before any heat pump is sized
- Hybrid setups that keep your furnace as the deep-cold backup
- Running-cost comparison built from your Oshawa Power and Enbridge bills
- Licensed refrigeration techs and ESA-licensed electrical work

What gets in the way of a heat pump in an older Oshawa home
None of these are deal breakers. They are the things we look for during the quote visit so they never become surprises on install day.
Your ducts were sized for a 1960s furnace
A heat pump moves roughly 400 cubic feet of air per minute per ton, and old trunk lines were never built for that. We measure static pressure, compare supply and return sizes to the airflow the unit needs, and size the heat pump to what the ducts can carry. Where a return is missing, we add one.
The furnace is fine but the air conditioner just died
That is the ideal moment for a hybrid. The heat pump takes the old AC's spot on the furnace plenum, uses the furnace blower, and handles cooling plus most of the heating. The furnace stays as the backup for the coldest nights, so nothing you already paid for goes to waste.
The upstairs of a wartime house has no return air
Many 1940s and 1950s homes have supply registers upstairs and not a single return, so warm air pools under the roof in summer and the heat pump cannot do its job. We add a return where the framing allows, or put a ductless head in the upstairs bedroom and let the ducted system serve the main floor.
You heat with gas and wonder if the rebate is worth the bother
Enbridge-heated homes get the smaller Home Renovation Savings Program amount, commonly up to $2,000, and the paperwork is ours to handle, not yours. We build the running-cost comparison from your real Oshawa Power and Enbridge rates so you can see what the heat pump saves before you sign.
An addition or attic conversion runs on electric baseboards
Baseboards turn one unit of electricity into one unit of heat. A ductless cold-climate heat pump for that space gives several units of heat for each unit of hydro, and a home heated mainly by electricity can qualify for the higher rebate tier, up to $7,500.
The water heater still vents up the old chimney
A heat pump on its own does not touch the chimney. If you replace the furnace at the same time, though, the chimney is left serving only the water heater, and that raises the liner question. We plan the furnace, water heater and chimney together so you get one answer, not three.
Lake wind through a drafty brick wall makes you doubt a heat pump
The heat-loss number decides this, not the age of the house. We calculate it room by room, then check the chosen unit's capacity at -15°C against it. The Midea EVOX G3 and Kepler models we install are rated to -30°C, and in a hybrid the furnace covers whatever is left.
The furnace closet has no room for a bigger coil
Older bungalows often have the furnace tucked in a closet with inches to spare. We measure the plenum height, the clearances and the condensate route before we pick the coil and air handler, so the quote matches the space you have.

How a heat pump install goes in an older Oshawa home
Older houses reward a careful order of operations. This is ours.
- 1
Measure the ducts and the panel
We test static pressure, check supply and return sizes, look at the plenum and confirm the panel can take a 240V circuit. The heat-loss calculation follows, and then the written, guaranteed quote.
- 2
Confirm the rebate before booking
The model has to be on NRCan's qualified products list and pre-approval has to be filed before installation. We confirm your eligibility and tier first, since program terms can change.
- 3
Install day
Licensed refrigeration techs fit the coil or air handler, set the outdoor unit on a pad clear of snow and roof drip lines, run the line set and drain, pull a vacuum and weigh in the charge. ESA-licensed electrical work covers the circuit.
- 4
Commission and hand over
We set the balance point so the furnace takes over at the right outdoor temperature, record the commissioning readings, register the warranty and file the final rebate documents.

Hybrid or all-electric? The Oshawa Power and Enbridge math
Most Oshawa homes come to us with a working gas furnace and a dead or dying air conditioner, so the practical question is whether to keep the furnace. In almost every case the answer is yes, at least for now. A hybrid system lets the heat pump carry cooling and the heating from roughly October to April on most days, while the furnace fires only on the deep-cold nights when gas is the cheaper fuel.
Where the furnace changes is the balance point, the outdoor temperature at which the thermostat hands over from heat pump to furnace. We set it from your actual Oshawa Power electricity rate and your Enbridge gas rate, not a rule of thumb. The colder it gets, the less heat the heat pump makes per dollar, and the balance point is where the two fuels cost the same.
- Gas furnace in good shape: hybrid, with the furnace as backup
- Furnace near the end of its life: hybrid with a new furnace, or an electric air handler if you want off gas
- Baseboard-heated addition: ductless heat pump for that space, higher rebate tier may apply
- Ducts too small to fix: ductless multi-zone instead of forcing a ducted unit
Changing the furnace at the same time raises the venting and chimney questions we cover on our Oshawa HVAC page. For ratings, HSPF2 and backup options for homes anywhere in Ontario, read the province-wide cold-climate heat pump page.

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.

Frequently asked questions
How much does heat pump installation cost in Oshawa?
Cold-climate heat pump installation in Oshawa starts at $5,500 installed. Installed pricing depends on size and installation requirements, such as duct repairs, an added return or panel work in an older home, and every item is listed on a guaranteed written quote.
Will a heat pump work with the old ductwork in my Oshawa house?
Usually, once the ducts are measured. We test static pressure and compare duct sizes to the airflow the heat pump needs, then size the unit to match or add a return where a room is starved. If the ducts truly cannot carry it, a ductless system is the honest alternative.
Should I keep my gas furnace when I add a heat pump?
Yes, if the furnace is in good condition. A hybrid system uses the heat pump for cooling and most heating days and the furnace for the coldest nights, and we set the switch-over point from your Oshawa Power and Enbridge rates.
How long does a heat pump installation take in an older Oshawa home?
A hybrid installation on existing ducts is usually a one-day job. Adding a return, replacing the furnace at the same time or upgrading the panel can stretch it, and the quote states the schedule so you are not guessing.
Does an Oshawa home on Enbridge gas qualify for the heat pump rebate?
It can. Gas-heated homes get the smaller Home Renovation Savings Program tier, commonly up to $2,000, while homes heated by electricity, oil, propane or wood can receive up to $7,500. The model must be on NRCan's qualified list and pre-approval must be in place before installation, and program terms can change.
Can I finance a heat pump in Oshawa and still get the rebate?
Yes. Financing is available at 0% interest for 3, 6 or 9 months or as an open loan from 2.99% on approved credit, and the rebate is paid after the installation is complete.
