Heat Pump Installation
Heat pumps have changed dramatically in the past five years. Modern cold-climate models work effectively down to -25°C and below — well past the -22°C design temperature for Halton Hills — and Ontario's current rebate landscape makes the upfront math more attractive than it's ever been. For many Georgetown homeowners, a heat pump install in 2026 means a system that heats and cools the home year-round, cuts annual energy costs by 30–50% versus an old gas furnace, and pays back its premium upfront cost faster than most expect.
That said: heat pumps aren't right for every home. Older homes with poor insulation, undersized ductwork, or aging electrical service may need other upgrades first. We do the heat-loss math, the electrical assessment, and the rebate stacking properly — and we'll tell you honestly if a hybrid system (heat pump + gas furnace backup) makes more sense than a fully-electric setup. Most Halton Hills installs we recommend are hybrid, because it captures the full rebate stack, keeps winter reliability rock-solid, and gives you the option to lean further into electric later.
When a heat pump makes sense
Heat pumps are not just for new builds. The right Halton Hills scenarios for installation:
- Your existing furnace is at end-of-life (12+ years) and replacement is on the table anyway. Adding a heat pump component to a furnace replacement project captures the full rebate stack.
- You want central air conditioning AND want to upgrade your heating efficiency — a heat pump does both, replacing the need for a separate AC condenser.
- You currently heat with oil or propane. OHPA (Oil to Heat Pump Affordability) plus federal and provincial rebates can cover $15,000–$22,500 of the install cost — often making conversion essentially free or near-free.
- You're committed to reducing your home's emissions and have insulation/envelope reasonable for 2026 standards. Heat pumps run on electricity from Ontario's mostly-clean grid (about 90% emission-free) versus burning gas on-site.
- You're adding a finished basement, addition, or zone that doesn't have ductwork. Ductless mini-split heat pumps are the right answer there — see our ductless page.
- You're in Glen Williams or another area without natural gas service and currently rely on propane or oil. Heat pump conversion math is dramatically favourable.
How a heat pump install goes with us
- 01
Heat-loss & electrical assessment
We do a Manual J heat-loss calculation on your home, evaluate your existing ductwork capacity for the higher airflow heat pumps need, and check your electrical service (heat pumps typically need a dedicated 30–60 amp 240V circuit, and older 100A panels may need an upgrade). This is non-negotiable due diligence — heat pump installs go badly when this step is skipped.
- 02
System design
Based on the assessment, we recommend either a fully-electric heat pump (right for tighter newer homes), a hybrid heat pump + gas furnace backup (right for most Halton Hills homes with existing gas service), or a ductless system (right for spaces without ducts). Each comes with clear sizing, equipment recommendations, and rebate eligibility.
- 03
Rebate paperwork
Heat pump rebates have the most complex stack of any HVAC install — HRS, Greener Homes Loan, OHPA if applicable, local utility, sometimes municipal. We file every form. You sign and we submit.
- 04
Installation
Heat pump installs typically run 1–2 days. The outdoor unit goes on a pad or wall-mount bracket, indoor coil and air handler integrate with your ductwork, refrigerant lines run between, and electrical/control wiring ties into your existing system. We commission the system, run cooling and heating cycles, and verify performance against design specs.
- 05
EnerGuide post-retrofit assessment
For Greener Homes Loan eligibility, a Registered Energy Advisor performs a post-installation EnerGuide assessment. We coordinate this so it actually happens — many installs lose rebate money because the post-retrofit assessment gets forgotten.

Owner walkthrough
Heat pumps work differently from furnaces — they run longer cycles at lower output, which is more efficient but feels different. We walk you through what's normal, optimal thermostat settings, and what to watch for in the first heating season.
Cold-climate heat pumps we install
Not every heat pump on the market handles Ontario winters. We install only models with verified cold-climate performance — rated for full capacity at -15°C or lower, with backup operation down to -30°C:
What heat pump installation costs in Halton Hills
Heat pump installation pricing varies more than other HVAC equipment because of the system type, electrical work needed, and rebate offsets:
- Hybrid heat pump + existing gas furnace: $11,000–$16,000 installed before rebates. After Ontario HRS + Greener Homes stack: $5,500–$10,500 net.
- Fully-electric heat pump (ducted): $13,000–$20,000 installed before rebates. Net after rebate stack: $7,000–$13,000.
- Cold-climate ductless mini-split (single zone): $5,500–$8,500 installed. Net after rebates: $3,000–$5,500.
- Multi-zone ductless (3+ heads): $11,000–$22,000 installed. Net after rebates: $6,500–$15,000.
- Oil-to-heat-pump conversion: pricing similar to above, but with OHPA + Greener Homes + HRS stacking, oil-heated homes often see net costs of $0–$5,000 — covering the entire conversion.
Electrical service upgrades (if your panel is undersized) typically add $1,800–$3,500. We assess this upfront so you know.
Heat Pump Installation questions
Do heat pumps actually work in Ontario winters?
Yes — modern cold-climate heat pumps work very well. Mitsubishi Hyper-Heat and Daikin Aurora units, for example, deliver 100% rated capacity at -15°C and continue operating to -30°C and below. Halton Hills' design temperature is -22°C, well within operating range. The myth that 'heat pumps don't work in cold climates' is based on equipment from 10+ years ago — modern systems are a different generation. That said, in extreme cold snaps (-25°C+), a hybrid system that switches to gas furnace backup is more cost-efficient than running the heat pump alone.
What's a hybrid heat pump system and why do you recommend it?
A hybrid system pairs a cold-climate heat pump with your existing (or new) gas furnace, controlled by a smart thermostat that automatically chooses the more efficient heat source based on outdoor temperature and gas/electricity pricing. Below a 'switchover temperature' (typically -10 to -15°C), the gas furnace takes over. Above that, the heat pump runs. Result: optimal efficiency year-round, full Ontario rebate eligibility, and gas-heat reliability for the coldest 5–15 days a winter when the heat pump's COP starts dropping. For most Halton Hills homes with existing gas service, this is the smartest configuration.
How much can I actually save on energy bills?
It depends on what you're replacing and your gas/electricity pricing. Typical scenarios for a Halton Hills home: replacing a 90% AFUE gas furnace with a hybrid heat pump system → 15–25% reduction in heating costs. Replacing oil heating with a fully-electric heat pump → 60–75% reduction. Replacing electric baseboards with a heat pump → 50–65% reduction. Adding a heat pump where you previously had no AC means you do gain that load, but the heat pump's cooling efficiency is also high (SEER 18+ on modern units), so net AC cost is modest.
What rebates can I stack?
For a qualifying cold-climate heat pump in Ontario in 2026: Home Renovation Savings (HRS) base rebate $4,000–$7,500 depending on heating source displaced; Canada Greener Homes Loan up to $40,000 interest-free (not a grant — financing); Toronto Hydro / Hydro One / local utility incentives $250–$500 typical; for oil-heated homes, OHPA adds $5,000–$15,000. Total stack: typically $4,000–$8,000 in actual rebate value for gas-replacement installs, $20,000+ for oil conversions. Eligibility rules are detailed; we handle the full application on every install.
Will my electrical panel handle a heat pump?
Most modern 200A panels handle a heat pump install with no upgrade. Older 100A panels often need either a panel upgrade or a load management device. We assess this on the in-home consultation — there's no surprise after install.
Do I need an EnerGuide audit?
For the HRS program alone, no — we apply directly. For the Canada Greener Homes Loan, yes — both a pre-retrofit and post-retrofit EnerGuide assessment by a Registered Energy Advisor are required. We coordinate the assessments so they happen on schedule. The pre-retrofit assessment cost is reimbursable up to $300 through the program.
What about Glen Williams homes without natural gas?
Glen Williams and several other Halton Hills hamlets don't have natural gas service. Currently most homes there run on propane, oil, or electric baseboards. Heat pump conversion in these scenarios is often the highest-ROI HVAC investment we see — particularly for oil heat, where the OHPA rebate alone often covers the bulk of conversion cost. We've done a number of these and the math is dramatic. Worth a free assessment.
How long do heat pumps last?
Properly-sized, properly-installed cold-climate heat pumps from major brands typically last 15–18 years on the outdoor unit and 18–22 years on the indoor air handler. That's comparable to a furnace lifespan, but with the bonus that you've also been getting AC out of the same equipment those whole years.
