Furnace replacement FAQs
When should you replace a furnace?
Replace a furnace when the current unit is more than 15 years old and requires frequent fixing, or when repairs cost more than half the replacement cost.
Signs a furnace should be replaced:
Energy bills are increasing.
Rooms heat unevenly.
Fuel lines rust or system chamber cracks.
The thermostat malfunctions.
The furnace cycles on and off frequently or makes loud noises.
Dust or soot buildup appears.
Interior air smells like a gas leak.
The gas-furnace flame is yellow instead of blue.
How long does it take to replace a furnace?
Replacing or installing a new furnace takes 4 to 18 hours, depending on the fuel type, size, and job complexity. Extra time applies for modifying ductwork, electrical, or gas lines, adding vents or zoning, or retrofitting a larger furnace.

Choose HVAC professionals with certifications from:
American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE)
State-certified natural gas journeyman training programs in gas fittings
Avoid choosing the lowest bids that signal low-quality work.
Select licensed, insured, and bonded HVAC contractors.
Read their reviews on HomeGuide and Google.
Request copies of estimates, plan diagrams, heating-load calculations, equipment orders, permits, warranties, and contracts.
Verify the estimates include material, labor, equipment costs, and the installation schedule.
Set up a payment schedule. Never pay in full up front.
Ask the questions below before signing a contract.
