How much does a new furnace, AC or heat pump cost in Pennsylvania?

What does heating and cooling work cost?

It depends far more on the job than on the trade. A repair visit is usually a few hundred dollars; a new system is usually several thousand. The figures below come from two published cost surveys, Angi and HomeAdvisor. Both are national. Neither publishes a figure for Pennsylvania or for any county, and both pages show a location-based estimate that changes with the reader, so that estimate is not used here.

ENERGY STAR describes a heating and cooling system as one of the largest purchases you will make as a homeowner. That is the reason to read a quote line by line.

What do repairs and tune-ups cost?

HomeAdvisor reports these national figures:

• Any HVAC repair: an average of $350, with jobs running from $100 to $3,000.
• Furnace repair: an average of $318, with most homeowners paying $133 to $505.
• Labor: $100 to $250 an hour on its HVAC repair page, plus an initial service call of $100 to $250. Its furnace page gives $50 to $150 an hour and a trip fee equal to at least one hour, with extra charges on weekends, holidays and at night.
• Tune-up: $80 to $100 for an inspection and $125 to $200 for a full tune-up.

Angi puts yearly HVAC maintenance fees at $60 to $550.

The price of a repair is mostly the price of the part. HomeAdvisor's furnace repair page lists an ignitor at $150 to $500, a gas valve or control board at $200 to $600, and a blower motor at $150 to $2,000. Its HVAC repair page puts a compressor at $800 to $3,000 and coil repair at $600 to $2,400.

What does a new system cost?

Some notes on the table. Angi gives a national average of $4,814 for a new furnace, from 11,869 projects, with most homeowners paying $2,822 to $6,897. Its heat pump page gives an average of $6,087 from 4,719 projects. HomeAdvisor's air conditioner page gives an average of $5,978. For a complete system, furnace and air conditioning together, HomeAdvisor gives an average of about $7,500, with most paying $5,000 to $12,500 and some jobs reaching $22,000.

The mini-split range is wide: HomeAdvisor says the price depends on the system's size and how many air handlers you need. A propane furnace, which Angi lists at $3,700 to $14,200, is worth asking about separately if your home is on bottled gas.

What moves the price up or down?

The surveys name the same handful of things.

• Size of the equipment. Angi prices a 3-ton heat pump at $3,900 to $6,200 including labor; bigger units cost more.
• Fuel and type. Angi's range for an oil furnace starts at $6,750, against $3,800 for gas and $2,000 for electric.
• Ductwork. Angi puts new ductwork at about $2,000 to $5,000 and HomeAdvisor at $1,000 to $2,700.
• Removal and permits. Angi lists $60 to $330 to remove the old furnace, and $400 to $1,500 for permits where a town requires one.
• Labor time. HomeAdvisor says an air conditioner installation usually takes four to eight hours, at $300 to $1,600 in labor.

Local permit fees are set by the municipality. In Philadelphia, for example, the city's mechanical permit page lists a $100 filing fee credited toward the permit, and $69 for each appliance in a one- or two-family home when submitted separately.

Is there still a federal tax credit?

Not for work done now. ENERGY STAR says the federal tax credits for efficient furnaces, boilers, central air conditioners and heat pumps were available through December 31, 2025. They paid 30 percent of the cost, up to $2,000 for a heat pump and up to $1,200 for the other equipment. If a quote still deducts a federal credit from the price, ask the company to show you where it comes from.

How do you compare two quotes fairly?

ENERGY STAR's advice for hiring a heating and cooling contractor gives the checklist:

• Get written, itemized estimates, and compare cost, energy efficiency and warranties. It adds that the lowest price may not be the best deal if the equipment is less efficient, because your energy costs will be higher.
• Expect a home evaluation. A bigger system is not always better. The contractor should size the system to your house, insulation and windows, and look at the ducts.
• Get model numbers in writing. The signed proposal should list project costs, model numbers, schedule and warranty terms. Two quotes for "a 3-ton system" are not comparable until you know which units they are.
• Ask about the extras. Removal, permits, duct changes, a new thermostat (HomeAdvisor puts thermostat upgrades at $150 to $260) and electrical work are often priced separately.

Should you repair or replace?

Age is the starting point ENERGY STAR gives. It suggests considering replacement when a heat pump or air conditioner is more than 10 years old, or a furnace or boiler is more than 15 years old, and when repairs are frequent and energy bills are rising. It also warns that big air leaks in the house and the duct system are sometimes the real problem rather than the equipment.
