Des Moines, Iowa: HVAC Replacement Cost Calculator

Replacing an HVAC system in Des Moines typically runs $3,500 to $7,000 for a gas furnace alone, $4,000 to $7,500 for central air conditioning, and $7,500 to $13,000 when you replace both at once. Heat pumps land between $6,000 and $12,000 installed, while a ductless mini-split system ranges from $3,500 to $10,000. These are installed prices that include equipment and labor, and Des Moines labor rates sit just under the national average, with HVAC technicians in the metro earning about $30.35 an hour.

Worked example

Take a 1,700-square-foot two-story home in Beaverdale with a 20-year-old gas furnace and an outdoor AC condenser of about the same age. Because both pieces are at end of life and share the same blower and refrigerant line set, most Des Moines contractors would quote the pair together rather than one at a time. A mid-efficiency furnace and a standard-efficiency AC with existing ductwork reused would land near the middle of the $7,500–$13,000 combined range, roughly $9,500 to $10,500. Pushing into high-efficiency equipment, adding a variable-speed blower, or repairing undersized return ducts moves the quote toward the $13,000 end.

Frequently asked questions

Is a heat pump a good choice for Des Moines winters?

Des Moines sits in climate zone 5, so winters are cold enough that most homeowners pair a heat pump with backup heat rather than relying on it alone. Heat pump installs here run $6,000 to $12,000, which overlaps heavily with the $7,500 to $13,000 range for a conventional AC-and-furnace pair, so the decision often comes down to your electric and gas rates rather than upfront price.

Why replace the furnace and AC at the same time?

A gas furnace alone runs $3,500 to $7,000 in Des Moines and central AC alone runs $4,000 to $7,500, so buying them separately can total more than the $7,500 to $13,000 combined range. The two units share a blower cabinet and refrigerant lines, so doing both in one visit avoids paying twice for the same labor and prevents mismatched equipment.

How much of my Des Moines HVAC quote is labor?

Labor is a substantial share of any installed price. HVAC technicians in the Des Moines area earn about $30.35 per hour, and local labor costs run slightly below the national benchmark at an index of 0.97, which is why identical equipment can price a bit lower here than in higher-cost metros.

What does a ductless mini-split cost in Des Moines?

Ductless mini-splits range from $3,500 to $10,000 installed in the Des Moines area, depending on how many indoor heads you need. A single-zone unit for a finished attic, sunroom, or converted garage sits at the low end, while a multi-zone system covering several rooms of an older home without ductwork approaches the top of that range.
