What a New Furnace Installation Includes
Every installation starts with a free estimate. I do a proper Manual J load calculation so the system is sized for your specific house. An oversized furnace short-cycles, wears out faster, and leaves the house humid during shoulder seasons. Getting the size right costs nothing extra and makes a real difference in comfort and operating cost.
Remove and haul away the old unit

Commission the system and verify proper combustion
I install Trane and RunTru by Trane as my primary gas furnace lines. Both are built in the same Trane factory. I also install Amana, Carrier, and American Standard. Financing available through Synchrony, Wells Fargo, Wisetack, Klarna, and JB Financing.

>Gas vs. Electric Furnace
In Central Oklahoma, most homes run gas. Gas furnaces are cheaper to operate and heat faster on those January mornings when temps drop to single digits. Electric furnaces or air handlers make sense when there’s no gas line or when paired with a heat pump. I’ll walk you through the right choice at the estimate.
Frequently Asked Questions
How much does a new furnace cost in Oklahoma?
A standard gas furnace replacement in Central Oklahoma runs $3,200 to $6,500 installed, depending on efficiency (80% vs. 96% AFUE), tonnage, and ductwork modifications. I provide a firm written quote at the free estimate. No surprises on installation day.
How long does furnace installation take?
Most replacements are completed in a single day, typically 4 to 6 hours. I remove the old unit, install the new one, connect gas and venting, verify combustion, and commission the thermostat before leaving.
What size furnace do I need for my Oklahoma home?
Sizing depends on square footage, insulation, window area, and ceiling height. I use Manual J load calculations rather than rule-of-thumb guesses. An oversized furnace is a common mistake that causes short cycling, humidity problems, and premature wear.
Do you offer financing on furnace installation?
Yes. Financing is available through Synchrony, Wells Fargo Home Projects, Wisetack, Klarna, and JB Financing, offering same-as-cash promotional options and standard financing with terms up to 84 months, subject to credit approval. I’ll walk you through the options at the estimate. Call 405-375-4822.
Is a high-efficiency furnace worth it in Oklahoma?
A 96% AFUE furnace costs $400 to $700 more than an 80% unit. In Central Oklahoma, gas bills are moderate and the heating season is shorter than northern states. Payback is typically 7 to 10 years. If you plan to stay in the house long-term, the 96% is worth it.
