Guelph HVAC facts that shape the decision
Before anyone talks equipment, these four things decide what makes sense for your house.
- UtilitiesAlectra hydro, Enbridge gas
Your electricity comes from Alectra Utilities and your gas from Enbridge. The price gap between the two drives the whole heat pump calculation.
- ClimateColder nights than Lake Ontario towns
Guelph sits inland, away from the lake's softening effect, so winter nights run colder. Equipment has to hold its output well below -15°C.
- HousingStone homes to new subdivisions
Historic stone homes downtown, 1970s and 1980s family houses, newer south-end subdivisions and student rentals near the university.
- Rebate tierGas homes: commonly up to $2,000
Homes heated with Enbridge gas fall in the smaller tier. If your home runs on electric, oil or propane heat, the ceiling is up to $7,500.
Who calls a Guelph HVAC contractor about efficiency
People reach the heat pump question from different places. Here are four common starting points.
Going fully electric
A cold-climate heat pump paired with an electric air handler removes the gas furnace entirely. We check your panel and plan the 240V circuits before you commit.
Family houses from the 1970s and 1980s
Original ducts, an aging AC and a furnace near retirement make these houses a natural fit for a heat pump that replaces the AC and most of the heating.
Owners of student rentals
Near the university, owners want low running costs and fewer breakdowns. We price durable equipment and smart thermostats that keep settings in a sensible range.

Efficiency problems an HVAC technician in Guelph can solve
These usually start as nagging doubts about bills or comfort. Each one has a measurable answer.
You want off gas but dread what the hydro bill will do
We estimate your yearly heating load from past gas use, then model the heat pump's electricity use at Alectra rates. You see both bills side by side, before and after rebates.
Your heat pump quote never mentioned a switchover temperature
In a hybrid system, the switchover point decides when gas takes over from the heat pump. We set it from your rates and comfort, and show you how to change it later if prices shift.
The old AC died and you're unsure what should replace it
A heat pump costs more than a plain AC, but it cools just the same and also heats for much of the year. We price both, so you can see the gap in cost and in running expense.
The south-end house is fairly new but the bills aren't low
Builder equipment is often single-stage and sized by rule of thumb. We check sizing with a heat-loss calculation and look at two-stage or inverter equipment that runs longer at lower output.
Upper rooms in a downtown stone house overheat each summer
Older stone homes often have little or no ductwork upstairs. A ductless heat pump cools those rooms in July and covers a good share of the heating in spring and fall.
Someone told you heat pumps quit in real cold
Older models did lose output fast as it got colder. Today's cold-climate units like the Midea EVOX G3 are rated to heat down to -30°C and keep strong capacity at -15°C.
Your hydro bill is on time-of-use rates and you wonder when the heat pump will run
It runs when the house needs heat, which in winter means a lot of overnight and early-morning hours when rates are lowest. A smart thermostat can hold a slightly lower setting through the afternoon peak and recover before dinner. Ontario utilities also offer other rate plans, and we'll look at which one suits a heat pump household before you commit to one.

Guelph installed prices before rebates and running costs
Efficiency math needs three numbers: the installed price, the rebate and the running cost. This table covers the first one. The quote adds the other two for your house.
| Service | Typical price in Guelph |
|---|---|
| Cold-climate heat pump, installed Midea EVOX G3 or Kepler, 2 to 5 ton, rated to -30°C | From $5,500 |
| High-efficiency furnace, installed Lennox ML296V or Midea MGH96, 96% to 97% AFUE, two-stage variable-speed | From $3,300 |
| Central air conditioner, installed Lennox or Midea, sized from a heat-gain calculation | Written quote |
| Ductless mini split, one zone Midea or Kepler wall unit with outdoor unit and line set | Written quote |
| Furnace repair Diagnostic visit plus common parts such as ignitors, flame sensors and capacitors | Quote after diagnosis |
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.

How we build a Guelph running-cost estimate
Most heat pump savings claims come from a brochure. Ours come from your bills. Here's the method.
- Your past year of Enbridge gas use, in cubic metres, tells us how much heat the house actually needed, once we subtract the water heater and the stove
- The heat-loss calculation checks that figure against the house itself: the windows, insulation and air leakage of a stone home downtown or a 1980s house in Kortright Hills
- The heat pump's efficiency changes with outdoor temperature, so we model it against Guelph's typical winter hours rather than a single average
- Alectra's electricity rate and Enbridge's gas rate, including delivery charges, go in as they appear on your bills
The result is a before-and-after estimate for a hybrid system and for an all-electric one, with the rebate shown separately. It's an estimate, not a promise, because weather and rates move. But it's built from your house, and you can see every input on the 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
Will heat pump installation in Guelph lower my bills if I already have gas?
It can, depending on the gap between gas and hydro prices and how the system is set up. For gas homes a hybrid system often strikes the best balance, and we show you the estimate before you buy.
What's the difference between a hybrid and an all-electric heat pump system?
A hybrid system pairs a heat pump with a gas furnace that takes over in deep cold, while an all-electric system pairs it with an electric air handler for backup. Both cool the house in summer.
My Guelph house heats with Enbridge gas. Is the heat pump rebate still worth claiming?
Yes. Enbridge gas-heated homes commonly qualify for up to $2,000 through the Home Renovation Savings Program. Pre-approval must be in place before installation, and program terms can change.
Do I need an energy audit before a heat pump install in Guelph?
No, not for a heat pump on its own under the current program. You do need pre-approval before installation, and we file it for you.
Can you put heat pumps in Guelph student rentals?
Yes. Ducted or ductless heat pumps suit many rental houses, and we sort out access with your tenants once you give the go-ahead.
Is furnace installation in Guelph still worth it?
For some homes, yes. If your ducts or panel make a heat pump costly, a 96% to 97% AFUE two-stage furnace from $3,300 installed is a solid upgrade, and a heat pump can be added later.
How much does a heat pump cost in Guelph before the rebate?
A ducted cold-climate heat pump in Guelph starts from $5,500 installed. An Enbridge gas-heated home commonly qualifies for up to $2,000 back, and an electric, oil or propane home for up to $7,500. Installed pricing depends on size and installation requirements, and the quote you sign is guaranteed.
