How much does it cost to upgrade from oil heating to a heat pump in NB?

Switching from oil heat to a heat pump in New Brunswick costs $3,000-$18,000 depending on whether you choose a ductless mini-split or a central ducted system — before rebates that can reduce the net cost by $2,000-$6,000 or more through NB Power and federal programs.

The oil-to-heat-pump conversion is the most impactful energy renovation a New Brunswick homeowner can make right now, and it is happening across the province at a rapid pace. NB's housing stock has an unusually high concentration of oil heat compared to most Canadian provinces, and rising oil prices combined with maturing cold-climate heat pump technology have made this conversion financially compelling for most households.

For a ductless mini-split system, a single-zone unit providing heating and cooling for a primary living area costs $3,000-$5,000 installed. A multi-zone system with 3-4 heads covering most living areas of a typical NB home runs $7,000-$14,000 installed. Multi-zone systems suit homes where one or two heat pump heads can serve open-concept living spaces, with existing oil heat (baseboard electric or oil furnace) retained for bedrooms and less-used spaces. For many NB homeowners, this hybrid approach — heat pump as primary for 80%+ of heating hours, oil as emergency backup — provides the best balance of efficiency and peace of mind for cold snaps.

For a central ducted heat pump system replacing an oil furnace, costs run $8,000-$18,000 installed. If existing ductwork from the oil furnace is in good condition, an air handler replaces the furnace and connects to an outdoor heat pump unit. If ductwork needs modification or extension, add $2,000-$6,000 for duct work. A ducted system heats every room uniformly and is often preferred for two-storey homes where mini-splits leave upper floors inadequately served.

Electrical requirements add an important layer to oil-to-heat-pump conversions. Mini-split systems typically need one or more dedicated 240V circuits. If your panel is currently a 100-amp service (common in NB homes built before 1985), upgrading to 200-amp service adds $2,000-$5,000 for the electrical work alone, but it is often needed anyway for a modern home and unlocks the capacity for EV chargers, induction ranges, and other future upgrades. Plan this as part of the overall project cost.

After rebates, the economics shift significantly. NB Power's Total Home Energy Savings program offers rebates on qualifying heat pump systems — rebate amounts should be confirmed with NB Power for 2026 values. The federal Oil to Heat Pump Affordability Program has provided an additional $2,000-$5,000 for qualifying low- and moderate-income households. Stacking provincial and federal programs has allowed some NB homeowners to complete the conversion for net costs under $5,000 on systems that would have listed at $10,000-$15,000.

On operating costs, NB homeowners who have switched from oil to heat pump report annual heating bill reductions of 40-65%. With NB Power electricity rates and recent oil prices, the payback on a typical conversion (excluding rebates) runs 6-10 years. With available rebates factored in, payback periods of 4-7 years are realistic — followed by decades of lower operating costs and a home that also has air conditioning for summer comfort.

The installation must be done by a TSANB-licensed refrigeration mechanic — this is provincial law, not optional. Ask each contractor quoting the job to provide a heat load calculation for your specific home. A contractor who quotes without measuring your home's heat loss is guessing at system size, and an improperly sized heat pump either cannot keep up in cold weather or short-cycles and wears out prematurely. Get 3 quotes and compare scope, system brands, and warranties, not just price.
