What 96% AFUE means for your gas bill
AFUE is how much of the gas a furnace turns into heat for your home over a season. A furnace rated 96% AFUE, like the Goodman GM9S96, puts about 96 cents of every gas dollar into the house. Older furnaces typically run well below that, so a replacement can lower your heating bills as well as fix the reliability problem.
What's inside a Goodman 96% furnace
The GM9S96 uses an aluminized-steel tubular primary heat exchanger and a stainless-steel secondary heat exchanger that pulls extra heat out of the exhaust. A silicon nitride igniter lights the burners, a draft inducer moves combustion gases out through the vent, and a multi-speed ECM blower moves air through your ducts. A self-diagnostic control board stores fault codes, which makes future service faster.

How Air Summit installs a Goodman furnace
It starts with a free estimate: we look at the home, the ductwork, the venting and the gas line, then size the furnace to the house instead of copying the old one. A high-efficiency furnace vents through PVC pipe and drains condensate, so we plan both. On install day we put on shoe covers, lay down drop cloths, remove the old furnace, set and connect the new one, then fire it up and check it before we leave.
Goodman's lifetime heat exchanger, 10-year unit replacement and 10-year parts limited warranties on the GM9S96 require online registration within 60 days of installation. We register it for you.
Homes, new construction and commercial spaces
We replace furnaces in basements across the Lee's Summit area, and we also install furnaces and air handlers in new construction, and we handle commercial heating, including rooftop units for shops and restaurants.

Questions, answered.
How long does a furnace replacement take?
Most straightforward basement furnace replacements are done in a day. Jobs that need new venting, gas line work or duct changes can take longer; we'll tell you at the estimate.
Should I repair or replace my furnace?
If the furnace is older, needs a major part, or repairs keep stacking up, replacement usually makes more sense. We show you both options with real numbers, and estimates on new systems are free.
Can I replace my AC at the same time?
Yes, and many homeowners do so the indoor and outdoor equipment are matched. Pair a Goodman furnace with an Amana S-Series AC or heat pump; the S-Series is $500 off when you mention the website ad.
Do you offer financing on a new furnace?
Yes. Financing is available at 12.99% for up to 120 months, subject to credit approval through a third-party lender.
