Heat Pump Conversion in Mississauga

Heat pump unit + install only: $12,000–$22,000 (cold-climate ducted). Add 100A → 200A panel upgrade (often required): +$3,500–$6,000. Add ductwork resizing: +$2,000–$5,000. Add HRV/ERV pairing: +$3,800–$7,500. Bundled deep-retrofit: $25,000–$45,000. Hybrid (dual-fuel with high-eff furnace backup): +$3,500–$6,500 over equivalent ducted heat pump.

Canada Greener Homes Loan up to $40,000 interest-free over 10 years (federal). Ontario HRSP up to $10,000 (requires pre/post EnerGuide audit). Enbridge HER+ up to $6,500. Mississauga HELP Loan up to $125,000 via property tax. Typical mid-range Mississauga bundle stacks $15,000–$25,000 in combined rebates. RenoHouse prepares and submits all paperwork; final approval rests with the program administrator.

Yes. Cold-climate heat pumps (Mitsubishi Hyper-Heat, Daikin Aurora, Lennox Quantum, Bosch IDS Premium) maintain 100% rated heating capacity to about -15°C and continue operating with reduced capacity to -25°C without auxiliary heat. Mississauga's design temperature is -22°C; properly sized CCHPs cover the heating load for ~95% of winter hours. Hybrid (dual-fuel) configurations add a high-efficiency gas furnace as backup for the coldest 5–10 days, common in larger homes.

About 60–70% of pre-2010 Mississauga homes need a 100A → 200A upgrade to add a heat pump (50A breaker for indoor air handler, 30A for outdoor unit), especially when EV charger or generator loads are also planned. Manual J load calc determines whether the upgrade is mandatory or optional. Panel upgrade $2,500–$5,500. ESA permit and inspection coordinated by our certified electrician partner.

No — RenoHouse does NOT physically install gas-fitted or refrigerant equipment. TSSA G2 gas-fitter licensing and ODP refrigerant certification are held by our certified HVAC subcontractor partners (Enbridge HER+-registered firms). RenoHouse signs the construction contract, manages the project, pulls Building/ESA permits, prepares rebate paperwork, and finishes the construction wrap (drywall around new ducts, paint, hardwood refinish around equipment) in-house. The customer has one point of contact: us.

Mitsubishi Hyper-Heat (M-Series and P-Series H2i, rated to -25°C) — most common Mississauga install. Daikin Aurora (rated to -25°C with Aurora controller). Lennox Quantum (premium tier, smart load-matching, -23°C). Carrier Infinity 24 SEER Greenspeed. Bosch IDS Premium (-25°C). All units we specify are AHRI cold-climate certified and rebate-eligible. Equipment selection happens at site visit based on heating load, footprint, electrical capacity, and rebate requirements.

Heat pumps deliver heat at lower air temperatures than gas furnaces (~38–43°C vs. 49–54°C), so they need ~20–30% more airflow (CFM) to deliver the same BTUs. Existing Mississauga homes built for furnaces frequently have undersized supply trunks and undersized return-air paths — leading to noisy operation, short-cycling, and underperformance after a heat pump swap. Manual J load calc + Manual D duct design at the start of project determines whether resizing is needed. About 50% of pre-2010 Mississauga retrofits need at least one supply trunk replaced; about 30% need return-air upgrades.

Canada Greener Homes Loan: up to $40,000 interest-free over 10 years, no payments in the first year, repayable in quarterly installments. Eligible for heat pump installations meeting ENERGY STAR cold-climate criteria. Application requires (1) NRCan-Registered Energy Advisor pre-retrofit EnerGuide audit, (2) eligible equipment from registered installer, (3) post-retrofit EnerGuide audit, (4) submission package to NRCan. RenoHouse coordinates the audit referral and prepares the submission package; the loan is between the homeowner and the federal lender. Approval typically 4–8 weeks after post-audit.

Permit and EnerGuide pre-audit: 2–4 weeks before equipment install. Equipment install (outdoor unit, indoor air handler, refrigerant lineset): 2–4 days for typical residential. Electrical panel upgrade if required: 1–2 days. Ductwork resizing: 3–7 days. Construction wrap (drywall, paint): 2–5 days. Post-install EnerGuide audit: 1–2 weeks after commissioning. Rebate close-out: 4–8 weeks after post-audit. Total project clock: 6–10 weeks contract-to-commissioning, plus 2–3 months rebate processing.

(1) Furnace under 8 years old and serviced — wait for natural end-of-life unless deep-retrofit cost is funded by Greener Homes Loan. (2) 100A service plus active EV charger plus planned generator — panel upgrade is mandatory and may exceed available service capacity. (3) Heritage Conservation District with restrictive outdoor-unit placement rules — case-by-case feasibility. (4) Very small condos or apartments where ductless mini-split coverage isn't economic — sometimes electric baseboards are still the right answer. We tell you honestly at the site visit when heat pump is wrong-time-wrong-house.
