What Drives Heating System Costs in Renfrew County?
Heating system replacement costs in Renfrew County are shaped by the same variables as elsewhere in Ontario, but with some regional nuances. Rural properties often have longer service call distances — a factor that can add to installation and maintenance costs. Ductwork condition varies considerably in older rural homes, and many properties requiring a heat pump installation also need electrical panel upgrades to handle the additional electrical load. The following cost ranges reflect installed prices, including equipment and labour, in the Renfrew County region for 2026.
Furnace Replacement Costs by Fuel Type
Standard Gas Furnace (80% AFUE)
An 80% AFUE natural gas furnace — the minimum efficiency rating now permitted in Ontario for new installations — costs approximately $3,000–$5,500 installed. This includes the furnace unit, installation labour, flue connection, and gas line hookup. These systems are most common in Pembroke, Petawawa, Renfrew, and Arnprior where Enbridge natural gas distribution is available.
High-Efficiency Gas Furnace (95%+ AFUE)
A high-efficiency condensing gas furnace — rated 95% AFUE or higher — runs $4,500–$8,000 installed. The higher price reflects both premium equipment and additional installation requirements: condensate drainage for the secondary heat exchanger and typically PVC vent piping rather than traditional metal flue. The efficiency gain (15+ percentage points over an 80% model) reduces annual gas consumption meaningfully, with faster payback at current Ontario gas prices.
Propane Furnace
Propane furnace equipment and installation costs are broadly similar to natural gas: $3,000–$8,000 depending on efficiency rating. The key difference is ongoing fuel cost — propane consistently runs 1.5–2× more per BTU than natural gas. For rural Renfrew County homeowners currently on propane, the heat pump operating cost comparison is worth running before committing to another propane furnace.
Oil Furnace Replacement
Replacing a like-for-like oil furnace costs approximately $4,000–$7,000 installed. However, given the OHPA grant program and current oil price volatility, many homeowners planning to replace an aging oil system are choosing to evaluate a heat pump conversion instead. A new oil furnace is a reasonable choice when the home has no existing ductwork compatible with a heat pump, or when the homeowner plans to sell within a few years and switching systems creates too much project complexity.
| System Type | Installed Cost Range |
|---|---|
| Natural gas furnace (80% AFUE) | $3,000 – $5,500 |
| Natural gas furnace (95%+ AFUE) | $4,500 – $8,000 |
| Propane furnace | $3,000 – $8,000 |
| Oil furnace replacement | $4,000 – $7,000 |
| Air-source heat pump | $5,000 – $14,000 (before grants) |
| Ground-source heat pump | $15,000 – $35,000 (before grants) |
| Hydronic boiler system | $5,000 – $12,000 |
| Annual furnace tune-up | $150 – $350 |
| Emergency call (off-hours) | $200 – $500 + parts |
Heat Pump Installation Costs
Air-Source Heat Pump
A ducted air-source heat pump system — compatible with existing forced-air ductwork — costs $5,000–$14,000 installed before any grants. The wide range reflects home size, ductwork condition, refrigerant line length, whether a backup furnace is being retained or a fully electric system is installed, and whether an electrical panel upgrade is needed. Cold-climate models rated to −25°C or lower are strongly recommended for Renfrew County and carry a price premium over standard heat pumps, but perform far better through local winters.
Ductless Mini-Split Heat Pump
Single-zone ductless mini-splits (one indoor unit, one outdoor compressor) start around $3,000–$6,000 installed. Multi-zone systems covering several rooms or a full home run $8,000–$16,000 or more. These are ideal for homes without ducts, room additions, or as supplementary heating zones.
Ground-Source (Geothermal) Heat Pump
Ground-source systems are the most efficient heating option available but carry the highest upfront cost: typically $15,000–$35,000 depending on loop type (horizontal, vertical bore, or pond loop), ground conditions, and home size. Rural Renfrew County properties — many with sufficient land for horizontal loops — are good candidates technically, though the payback period is longer and the system is best suited to new construction or major renovations.
Hydronic Boiler Systems
Hydronic (hot water) boiler systems, which distribute heat through radiant floor tubing or baseboard radiators, cost approximately $5,000–$12,000 for the boiler and primary components — not including radiant floor installation if that component is new. These are common in older Renfrew County homes and provide very even, comfortable heat. Boiler replacements are generally straightforward; full radiant floor retrofits are a larger project.
Factors That Affect Your Installed Cost
- Home size and heating load — larger homes require larger-capacity equipment, which costs more.
- Ductwork condition — older or undersized ductwork may need modifications to handle a new system, particularly heat pumps which move more air volume than oil furnaces.
- Electrical panel upgrade — heat pumps typically require a 200-amp panel and a dedicated circuit. If your panel is 100 amps or older, an upgrade is needed — add $2,000–$5,000 for the ESA-permitted panel upgrade.
- Refrigerant line run length — longer distances between the indoor and outdoor heat pump units increase labour and refrigerant costs.
- Oil tank decommissioning — if replacing an oil system, the tank must be properly decommissioned or removed, which adds $500–$2,000 depending on tank location (above-ground vs. buried).
- Backup heat requirements — some cold-climate heat pump installations retain an existing furnace as backup; others install electric resistance backup strips. The configuration affects total cost.
- Service location — rural Renfrew County properties farther from Pembroke, Renfrew, or Arnprior may see higher travel/service fees from contractors.
After-Grant Costs: The OHPA & Greener Homes Loan Impact
For homeowners currently heating with oil, the grant landscape dramatically changes the net cost calculation:
- The Oil to Heat Pump Affordability (OHPA) program reduces heat pump installation cost by up to $15,000 — paid directly or as an upfront reduction depending on program delivery.
- The Canada Greener Homes Loan provides up to $40,000 interest-free for eligible energy upgrades including heat pumps. This can finance the remaining cost after grants with no interest burden.
Example scenario: a $12,000 cold-climate heat pump installation minus $15,000 OHPA = net cost of $0 for qualifying households. For installations above the grant ceiling, the Greener Homes Loan covers the remainder interest-free. The combination makes switching from oil to a heat pump financially viable for a wide range of Renfrew County homeowners.
