Notes

  • Where the number comes from. The national price for a 90% AFUE furnace replacement is $5,200 installed — gas furnace replacement pricing published for 2026. Labor is about 40% of that. Heating, Air Conditioning, and Refrigeration Mechanics and Installers in Iowa average $63,120 a year against a U.S. mean of $64,780 — a factor of 0.974 — so the labor half is scaled by that and the material half is not.
  • What is in the price: the furnace, removal and disposal of the old one, a new flue or vent kit, gas and electrical connections, a thermostat, permit and labor.
  • What is not: ductwork changes, a chimney liner where an 80% unit is orphaned by a water heater, and any return-air work the new blower needs. These are the lines that turn a $5,147 quote into a $6,433 invoice, so ask about each one before signing.
  • Why state matters more than people expect. Materials ship at national prices; crews do not move. Iowa sits below the national mean by 2.6%, which lands on 40% of the job and moves the total by $53.
  • Use this as a bid check, not a quote. It prices an average job in an average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

An 90% AFUE furnace replacement in Iowa

$5,147 is the typical installed figure, and bids normally land between $3,959 and $6,928. This is a job price, not a unit price.

Why this is not the national number

The same job priced at the U.S. average comes to $5,200 — this one is $53 less.

Heating, Air Conditioning, and Refrigeration Mechanics and Installers in Iowa average $63,120 a year against a U.S. mean of $64,780, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 49-9021. That is roughly $30 an hour of trade pay, a factor of 0.974.

Labour is about 40% of this job; equipment is the other 60% and it costs the same in every state. So only the labour half is scaled here.

$2,059 of labour, $3,088 of equipment.

The efficiency step is not only the box price

Going from 80% to 90% or above means the flue changes. A condensing furnace vents in PVC and produces acidic condensate that needs a drain — neither of which the old metal flue provides.

There is a second-order cost people meet at the worst moment: if a gas water heater shared that chimney, removing the furnace from it leaves the water heater orphaned in a flue far too large to draft properly. The fix is a chimney liner, and it is a line nobody quotes until the installer is on site.

Where the payback actually is

The jump from 80% to 96% saves roughly a sixth of the gas bill. In a cold zone with a large heating load that pays back in a handful of years; in a mild climate it may never pay back on fuel alone, and the honest reason to buy it is comfort from the variable-speed blower rather than the AFUE number.

Rebates change the arithmetic more than the sticker does

Utility and state rebates on high-efficiency equipment are frequently four figures and are rarely included in a quote. Check what is available before choosing the tier — it can make the 96% unit cheaper than the 90%.

Using this against a real bid

Three quotes on identical scope should cluster. One well under $3,959 usually means something was left out rather than found cheaper. One well over $6,928 is either a harder job than average or a crew that does not want the work.
