Heating Capacity and AFUE Guidance
This furnace is perfect for 600–1,000 sq. ft. homes in various climates when properly sized and installed. With a 40,000 BTU input rating and 96% AFUE efficiency, it is designed to provide dependable heating for compatible residential applications. Proper furnace sizing should always be confirmed through a professional load calculation based on climate, insulation, windows, ceiling height, layout, air leakage, and other home-specific factors.
Efficient Everyday Heating Performance
A 96% AFUE furnace provides high-efficiency gas heating performance by converting approximately 96% of fuel consumed into usable heat for your home. For example, a 40,000 BTU input rating at 96% AFUE provides approximately 38,400 BTUs of usable heating output. Because this is a 96% AFUE furnace, it uses PVC venting instead of the metal flue venting required for 80% AFUE furnaces. This furnace is designed for enhanced comfort control compared to basic single-stage equipment.
Advanced Airflow with a 9-Speed ECM Blower
The integrated 9-speed ECM blower motor provides improved electrical efficiency compared to older PSC blower designs. This blower helps support consistent air circulation throughout the home while reducing electrical consumption during operation.
Built for Long-Term Reliability
A heavy-gauge steel cabinet, durable hot surface igniter, self-diagnostic control board, and Goodman’s proven heat exchanger design work together to support long-term performance. The self-diagnostic controls simplify troubleshooting and service, while the insulated cabinet helps reduce operating noise.
Goodman Gas Furnace System: How Does it Work?
Goodman Gas furnaces provide dependable whole-home heating by using a controlled combustion process to create warm air and distribute it through the home’s ductwork.
Key components such as the burner, heat exchanger, blower motor, and venting system work together to deliver consistent comfort while helping maintain safe and efficient operation.
Understanding how these parts function together can make it easier to compare furnace options and choose a system that fits the home’s heating needs.

Customers Say
Multiple buyers report quiet, reliable operation from 60,000–100,000 BTU models, including a 96% efficient 80,000 BTU unit replacing an older 60–66% furnace, with one heating a 1,300 sq ft home in low 20°F weather and others noting lower energy bills and improved two-stage performance. Installations were often completed by homeowners in 6 to 22 hours, though some encountered loose screws, minor shipping damage, wiring cleanup, sensor or setup adjustments, and occasional delivery coordination issues.

- New FurnaceGreat unit! Showed up on time and in great condition. Packaging was excellent and very secure. All pieces were included. Got the plenum kit which came with a lot of metal screws too. Unit hooked up and is working great! I was without heat so having these guys to talk with and sort out details was key to my purchase. Contacting them during shipping to make sure everything was on time was easy and no hassle. Unit was well priced and I feel I got a great deal over all and isn't that what it's all about?
If I ever upgrade and add A/C I'll be buying from here only. Once you treat me right you keep my business until you don't. Only fair.Posted on
- Great furnaceThis furnace is replacing a Goodman I installed in 2002. Everything went smoothly but I wished it would be easier to read the wiring markers. I pretty much had to lay on the floor to see them because they're marked on the bottom not the top of the connections.

- 30 year old Furnace replacementFirst time installing a Goodman, I have replaced quite a few of the older models. Everything hooked up fine only issue was shutting off the R32 sensor , didn't realize i needed to do that until it was to late. Took a few attempts to reset the codes but after a quick video on YouTube from their links it was fixed. Over all I'm very happy with it and so is the customer. It's nice when the install takes less that 6 hours start to finish.

- Smooth RunningUnit runs smoothly as you'd expect for a new furnace. It replaced a 70,000 BTU from the late 80's and hasn't had any problems so far with low 20 degree weather in a 1,300 SF northern mid-west home.
My only hits on the quality would be there were several screws loose on the unit randomly all over, so we looked at it closely in case of the feared "Friday or Monday build". Perhaps this happens in shipping, or some fasteners like the gas hookup are left loose for ease of connecting gas first.
The cabinet had some damage I'd assume came during shipping, so it required some field adjustments to get the upper door on straight and hooking up the plenum. Pricing compared with about every other competitor, but the unit was available in stock and the reliability and customer service of HVACDirect won out with us.Posted on
- replacement insallthis is a furnace replacement. our heating installers use this brand all the time. though they were 4k for furnace and install, i figured I would give it a shot myself. it showed up packaged like a tank, so it was well protected, though the delivery company failed to call me prior to showing up, instead they left out in the driveway. unit isn't that heavy, shorter than old one. was pretty easy to install with gas, vents, and wires.
BE SURE to read the tag near the wire terminals about A2L. the furnace ran full fan only. you have to go into setting and tell it no, then it will work as it should. my nest thermostat allows for 2 stage heating which is absolutely amazing. house heats up way quicker, and it runs way less.
I myself being very handy at fixing things, if can do handy things, buy from here as prices are great, and fast shipping, and most things seem in stock a lot.Posted on
