What does furnace replacement gas typically cost in New Brunswick?

Furnace replacement in New Brunswick typically ranges from $4,500-$8,500 for a standard natural gas unit, with high-efficiency models reaching $6,000-$12,000 installed. The wide range depends on your home's size, existing ductwork condition, and efficiency rating you choose.

For a typical New Brunswick home (1,200-1,800 sq ft), expect these ballpark costs:

Basic efficiency gas furnace (80-85% AFUE): $4,500-$6,500 installed. These meet minimum code requirements but aren't eligible for utility rebates. Good for older homes where you're planning other major upgrades down the road.

Mid-efficiency units (90-92% AFUE): $5,500-$8,500 installed. The sweet spot for most NB homeowners — solid efficiency gains without premium pricing. Often qualify for NB Power rebates.

High-efficiency condensing furnaces (95%+ AFUE): $6,500-$12,000 installed. Maximum efficiency and utility rebates, but require additional venting and condensate drainage. Worth it if you're staying long-term.

What affects your final cost? Ductwork modifications can add $2,000-$5,000 if your existing system needs upgrading. Many 1970s-1990s NB homes have undersized returns or leaky ducts that should be addressed. Venting changes for high-efficiency units add $800-$1,500. If you're switching from oil to gas, expect gas line installation costs of $1,200-$3,000 depending on distance from the street.

The permit process requires a gas installation permit from TIS (Technical Inspection Services) — your contractor handles this, but it adds $150-$300 to the project. Only licensed gas fitters can install gas furnaces in New Brunswick, and TIS must inspect before the system can be activated. Never let an unlicensed contractor touch gas lines.

Smart timing considerations: Many NB contractors offer better pricing in spring and summer when demand is lower. Winter emergency replacements often carry 20-30% premiums due to urgency and limited availability.

Your first step should be getting quotes from at least three licensed gas contractors in your area. Ask specifically about NB Power rebates you might qualify for — these can offset $500-$1,000 of your upgrade cost. Also verify their TIS gas fitting licence and WorkSafeNB coverage before signing anything.
