Furnace Installation & Replacement in Carthage, MO
New gas and electric furnaces installed by certified technicians.
A new furnace is a 15–20 year decision, and the right install matters as much as the brand on the box. Escos Heating & Cooling installs new gas and electric furnaces across Carthage, Joplin, Webb City, Carl Junction, Neosho and surrounding Jasper, Barton and Newton County, MO.
We don't sell you a furnace from the front of the showroom — we size it for your house. Proper sizing means lower bills, more even temperatures, fewer breakdowns, and a system that lasts. Oversized furnaces short-cycle and wear out early; undersized ones never quite keep up. We use a real load calculation, not guesswork.
Our installations include proper venting and combustion air, a new flue when required, sealed and properly-sized return ductwork, electrical safety checks, a new high-efficiency air filter setup, and full system commissioning. We also re-evaluate your AC at the same time — installing a new furnace without checking the cooling coil and refrigerant matching is asking for trouble next summer.
Looking at brands — Goodman, Amana, Carrier, Trane, Rheem, Lennox — we install the right one for your budget, efficiency goals, and home. Financing makes it manageable: no interest the first year, then 7% after, so a new furnace doesn't have to mean draining savings.

Furnace Installation FAQs
How long does furnace installation take?
A standard residential furnace replacement in Carthage, MO takes 4–8 hours. Adding new ductwork or upgrading to a different fuel type can extend it to a full day.
What size furnace do I need?
We perform a Manual J load calculation rather than rule-of-thumb sizing. Square footage, insulation, ductwork, window count and Missouri's climate zone all factor in.
How much does a new furnace cost?
Most residential furnace installations in Jasper County run $4,500–$8,500 depending on AFUE rating, BTU size, and whether modifications to ductwork or venting are needed.
Should I get 80% or 95% AFUE?
A 95%+ high-efficiency furnace costs more upfront but uses 15% less fuel — payback in southwest Missouri is typically 5–8 years. For homes you'll stay in, it's usually worth it.
Do you offer financing for furnace installation?
Yes. Our in-house financing is no interest for the first year, then a low 7% rate after. Most homeowners qualify with a quick application.
