Furnace Installation in Decatur, Indiana
A new furnace is the biggest comfort decision a Decatur homeowner makes, and the one most often rushed in a cold snap. Summers Plumbing Heating & Cooling installs gas and electric furnaces, heat pumps, and dual-fuel systems for residential homes across Adams County — sized to the house rather than copied off the old unit’s nameplate. Trucks and install crews run from 702 Nuttman Ave in Decatur, not Fort Wayne. Estimates are free, in your home, with the price in writing. Current special: $200 off or 0% interest on furnace installation (see specials for this month’s details).

What’s Included in a Summers Furnace Installation in Decatur
- A Manual J load calculation on your house — not a guess from the old furnace’s size. Undersized and oversized units are a top cause of short cycling in older Decatur homes north of the St. Marys River and the farmhouses outside city limits.
- Removal and haul-away of the old furnace.
- New furnace, venting, condensate drain, and gas connection, with permit and inspection as required.
- A new filter rack and, where needed, return-air corrections so the furnace can breathe.
- Thermostat setup and a walkthrough of the system before we leave.
- Registration of the manufacturer’s warranty in your name.
Furnace Options for Adams County Homes
- 80% AFUE gas furnaces — the lower-cost option, common where an existing metal flue is already in place.
- 96%+ AFUE condensing furnaces — PVC venting, lower gas bills, and the models that often qualify for utility rebates and federal efficiency credits while available.
- Two-stage and variable-speed furnaces — quieter, steadier heat for larger or two-story homes with hot and cold rooms.
- Heat pumps and dual-fuel — a heat pump for the shoulder months with gas taking over on the coldest Adams County nights.
We install and service the major residential brands. We don’t install oil furnaces. Outside city limits, hard, iron-heavy well water can scale humidifiers and leave mineral film on coils — tell us if you’re on a well so we size condensate and filtration the right way.
What a New Furnace Costs in Decatur
Rather than a price range you can’t act on, we give you three written options at the estimate — good, better, or best. Financing with approved credit is available on every tier. Current install specials ($200 off or 0% interest) are applied when they run — confirm this month on our specials page. Removal of the old furnace, permit, and inspection are included in every quote.
How Fast Can You Install in Decatur?
Estimate within a day or two of your call, installation usually within a few days of approval, and same-week when you have no heat. A typical furnace swap takes one day; a furnace-and-AC system takes longer. The crew that installs it also handles the warranty follow-up.
Before and After Your Installation
If you’re deciding between fixing the old unit and putting in a new one, start with furnace replacement in Decatur for the repair-or-replace math. After installation, a fall furnace maintenance visit keeps the warranty valid and catches small issues before January. Need heat restored first? See furnace repair.

Furnace Installation FAQs for Decatur Homeowners
How long does a furnace installation take in Decatur?
Most straight furnace swaps finish in one day. A furnace-plus-AC changeout or a conversion that needs new venting or gas line work can take two. We’ll give you a clear schedule at the estimate.
Do you haul away the old furnace?
Yes. Removal and disposal are included in every installation quote.
What size furnace does my Decatur home need?
We run a Manual J load calculation — square footage, insulation, windows, and how the house is used. Copying the old nameplate is how homes end up short-cycling or never catching up on the coldest nights.
Is financing available on a new furnace?
Yes. Financing with approved credit is available, and when the install special is running you can choose $200 off or 0% interest. Ask when you book the estimate so we apply the current offer.
Do you install oil furnaces?
No. We install and service gas and electric furnaces, heat pumps, and dual-fuel systems for residential homes. If you’re on oil today, we’ll talk through conversion options that fit Adams County fuel and venting realities.
