What furnace repair costs for furnace repair.

What furnace repair costs

Prices in this category are quoted per unit — per square foot, per linear foot, per pier, per job — and the unit is where most quotes become incomparable. The table below is the range we verified in November 2026, with what each line includes.

JobTypical rangeNotes
Furnace repair$150-$600Diagnostic plus common parts
Furnace replacement$3,000-$8,00080-96% AFUE, installed
Tune-up and safety check$100-$250Annual
Heat pump installation$5,000-$12,000Including ductwork changes
Duct cleaning$300-$800Per system
Emergency call-out$200-$500Nights and weekends

What moves the price

  • Access. Height, water, tight side yards and finished interiors all add labour.
  • Prep. Cleaning, grinding, draining or removing an old system is often the largest hidden line.
  • Materials. The same job in a premium finish can double the material cost.
  • Permits and disposal. $100–$800 depending on the jurisdiction and the waste stream.
  • Season. Spring and autumn are busy; February is not.

What a quote should show

Ask for the same five lines from every contractor: unit price and quantity, prep included, materials by brand, permits and disposal, and the warranty. A quote that only shows a total is a price, not a scope.

The methods hub explains what each option actually does, and the problems hub starts with the diagnosis every quote should follow.

Is the cheapest quote a red flag?

Usually it is a scope difference — less prep, no permit, thinner material. Compare the five lines, not the total.

How long is a quote valid?

30 days is common; material prices move. Ask what happens if you sign after the window.
