Pennsylvania: HVAC Replacement Cost Calculator

Most Pennsylvania homeowners spend between $3,500 and $13,000 to replace an HVAC system, depending on what they're putting in. A gas furnace alone runs $3,500 to $7,000 installed, a central air conditioner runs $4,000 to $7,500, and replacing both at once runs $7,500 to $13,000. Heat pumps land between $6,000 and $12,000, and ductless mini-splits range from $3,500 to $10,000 depending on how many zones you need.

Worked example

Say you own a 1,900-square-foot two-story home outside Harrisburg with a 22-year-old gas furnace and a central AC unit that's on its last summer. Because the furnace and coil are replaced together, this falls in the AC-plus-furnace category at $7,500 to $13,000. With standard-efficiency equipment, existing ductwork in usable shape, and no major venting or electrical changes, a job like this typically lands near the middle of that range, around $9,500 to $10,500. Pushing to higher-efficiency equipment, adding a new liner for the flue, or repairing duct runs in an unconditioned attic moves it toward the $13,000 end.

Frequently asked questions

Is a heat pump worth it in Pennsylvania's climate?

Pennsylvania sits in climate zone 5, which means real winter heating loads, so a heat pump here needs to be sized and selected for cold weather performance. Installed costs run $6,000 to $12,000, above the $3,500 to $7,000 range for a gas furnace, so the payoff depends on your electric rates and whether you're replacing electric resistance heat or a gas furnace.

How much does it cost to replace just the air conditioner in Pennsylvania?

Central AC replacement alone runs $4,000 to $7,500 installed across Pennsylvania. If your furnace is also 15 or more years old, price out the $7,500 to $13,000 combined replacement at the same time, since the labor overlaps and you avoid paying twice to open up the same equipment.

Why do quotes for the same system vary by thousands of dollars?

Equipment efficiency tier, system size, and the condition of your existing ductwork, flue, and electrical panel all move the number. Labor is the other half of the bill; HVAC technicians in Pennsylvania average $31.19 an hour in wages, so a job that takes two days instead of one shows up clearly in the price.

What if my Pennsylvania home doesn't have ductwork?

Ductless mini-splits are the usual answer, running $3,500 to $10,000 installed in Pennsylvania. A single-zone system for one addition or converted attic sits near the low end, while a multi-zone setup covering several rooms of an older home approaches the top of the range.
