Furnace replacement & installation

When it's time for a new furnace, you deserve straight answers, not a sales pitch. John will help you choose a system that fits your home and your budget.

Watching your budget? See our affordable replacement options and starting prices.

When replacement makes sense

  • Your furnace is roughly 15–20 years old or more
  • Repairs are getting frequent or expensive
  • Some rooms are always too cold, or the house never feels comfortable
  • Heating bills keep climbing
  • A cracked heat exchanger or other safety problem has been found

What you get with Greenley

  • An honest recommendation. If a repair will do, we'll tell you.
  • The right size. A furnace that's too big or too small wastes money and wears out faster.
  • Efficiency options explained plainly. Standard vs. high-efficiency (95%+ AFUE) furnaces, and when a heat pump or dual-fuel system is worth it in Iowa.
  • Rebate help. We'll point you to the utility rebates you qualify for. See 2026 Iowa rebates.
  • Clean, careful installation and a walk-through of your new system.

We install and service all major brands.

Questions we hear a lot

How long does a furnace replacement take?

Most straightforward replacements are done in a day. John will tell you what to expect for your home.

Is there still a federal tax credit for a new furnace?

No. The federal 25C credit ended for equipment installed after December 31, 2025. Utility rebates are still available. See our rebates page.

Should I get a heat pump instead?

It depends on your home, ductwork and fuel. Many Iowa homes do well with a dual-fuel setup (a heat pump plus a furnace for the coldest days). John can walk you through it.

β€œHe was amazing. No upsale, he just quickly replaced a part he already had in his van. Professional and skilled are the words I would use to describe him.”
