QUICK FACTS

  • This furnace is ideal to heat a smaller house (depending on climate)
  • 30,000 BTU 96% efficient natural gas furnace
  • Requires plastic/PVC flue venting
  • Can be used in the upflow or horizontal orientation
  • Can be converted to an LP furnace with a conversion kit (sold separately)
  • Innovative design for electrical efficiency, safety, and lower sound output

30,000 BTU

The GMES960403AN Goodman gas furnace is 30,000 BTU’s, which is the smallest Goodman furnace size currently available. This BTU count is a measure of the input of the furnace per hour, while the output of this furnace is 28,800 BTU’s (30,000 X 96% AFUE) per hour. In ideal climate conditions, this 30,000 BTU furnace is usually used to heat a small house.

96% Efficiency Rating

The GM9C960303AN Goodman gas furnace is 96% efficient, and the standard furnace efficiency on the market today. This means that 96% of the gas going into the furnace is used to heat your home and the remaining 4% is lost out of the flue venting. Please note that all 96% furnaces must be vented using plastic/PVC flue venting, while anything higher than 90% efficient must be vented using plastic/pvc venting.

Natural Gas or LP Furnace

From the factory, the GM9C960303AN runs on natural gas. However all Goodman gas furnaces can be converted to propane using the furnace’s corresponding LP conversion kit, an optional accessory at an additional cost that consists of a replacement set of orifices and springs.

9-Speed ECM Blower Motor

Instead of the last generation PSC blower motor, the GM9C960303AN utilizes a 9-speed ECM motor, which uses less power and provides smarter air circulation. All of this causes an overall increase in the electrical efficiency of your furnace, which saves you money.

Warranty

With installation that follows your state and local codes and with online registration, all Goodman furnaces come with a 10-year parts and lifetime heat exchanger warranty through the manufacturer.

Durable Hot Surface Igniter

The hot surface igniter on modern Goodman furnaces are more durable than previous designs, decreasing related issues and lowering maintenance costs. These hot surface ignitors are also more efficient than standing pilot and older HSI designs, saving you even more money.

Self-Diagnostic Control Board

The Goodman brand has improved technology from years of production experience, allowing for a long-lasting product that rarely has any issues. However, if something does go wrong on the furnace, the control board has a set of sensors that allow it to diagnose basic issues, allowing for easy troubleshooting and to notify the owner if basic maintenance or warranty work is recommended. This increases the overall safety of the unit, for the furnace itself and the occupants of the home where it is installed.

Heavy Gauge Steel Cabinet

The heavy-gauge steel cabinet on new Goodman furnaces provide adequate protection to the internal mechanisms of the unit. The cabinet is also more air-tight than previous models, allowing for a quiet, more economical unit due to losing less heat and preventing more sound from exiting the unit.

Ease of Installation

The value of modern Goodman furnaces doesn't end at efficiency. Today’s Goodman furnaces feature many different connection options to reduce installation. The GM9C960303AN model has a more universal design, which consists of its ability to be installed in both an upflow or horizontal configuration. This allows for an easier installation in more locations, from your attic to your basement. The furnace also comes with color-coded low-voltage terminals that allow for a shorter and easier installation time, which decreases installation costs.

Please note that this furnace requires a drain kit if installed horizontally. Upflow configurations do not require the kit.

Customers Say

Across DIY and professional installs, buyers report quiet, reliable heating from 60,000 to 100,000 BTU models, including a 96% efficient 60K two-stage unit that lowered energy bills and an 80,000 BTU replacement that improved output over an older 60–66% efficient furnace. Installation is generally described as straightforward—even for first-timers taking up to 22 hours—with some noting wiring label visibility issues, loose or stripped screws, minor shipping damage, sensor error codes, and the need for small duct or gas line modifications.

    The ID fan pressure sensor was not working on the first day, giving an EE1 error, but it cleared by itself on the next day.

    Great 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.

    This 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.

    First 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.

    Unit 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.

    this 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.
