Finding your Goodman AC age is quite simple if you know where to look. Finding your Goodman furnace age is the exact same process.
Goodman HVAC equipment has to be by far the most popular brand I see daily. I don’t track the percentages, but I would guess well over 50% of the HVAC equipment I see as a home inspector is Goodman.
This is partly due to the brand’s low cost and widespread availability- even through internet sales where most brands of HVAC equipment are not available, Goodman is. When things are cheap and easy to get your hands on, you’ll no doubt see more of it.
Aging your Goodman air conditioning, furnace, or heat pump is easy if you know where to look on the label. Goodman is not the only brand that decodes their equipment like this either, aging Daikin HVAC equipment uses the same system.
The first 4 digits will give everything you need to know to age a piece of Goodman AC, Furnace, or Heat Pump. The first two digits will be the year of manufacturing, and the second two digits will be the month.
How to age a Goodman Gas Furnace?
A Goodman gas furnace will have the data label inside the upper compartment (usually along the left-hand side). Find the Serial Number, and look for the first 4 digits.
How to age a Goodman AC?
Goodman places their data label on their air conditioners along the bottom of the cabinet down where the line set connects to the condensing unit. These labels can be tricky to read sometimes as the sun will fade them out to the point you can’t read them.
The rules for a Goodman A/C unit are the same as a Goodman furnace. The first two digits of the serial number are the year the unit was manufactured, and the second two are the month.
The image below shows an A/C unit that was produced in 04-2021.
How to age a Goodman Heat Pump?
Aging a Goodman Heat Pump is exactly the same as aging a Goodman AC unit. The data plate will be in the same place as well (along the base of the unit). The unit pictured below was manufactured on 05-2013.
How Long Does Goodman HVAC Equipment Last?
In my world, Goodman HVAC equipment can catch a bad wrap for quality or a lack thereof.
In my opinion, I don’t think it’s that bad. Is there better stuff available? Sure. But for what you pay for Goodman equipment I don’t think you can gripe too much.
The truth is, most of the time a poorly performing HVAC system can be traced back to a shotty install. And since you can buy Goodman on the internet with no restrictions, a lot of this equipment gets installed by hacks that either do not know what they are doing or just don’t care if they do a bad job.
The most common HVAC installation errors I run across are:
- Poorly fitted filters racks so the evaporator coils become clogged with gunk.
- Air Ducts that are not properly sealed (see my review of Aeroseal to help with duct sealing).
- Little to no insulation in the attic or walls of the home. (Link to my DIY Attic Insulation Article)
- Improperly sized ductwork (you’d be shocked at how many homes do not have proper sized ducts).
- Improperly sized HVAC equipment (you’d also be shocked at the amount of equipment that gets sized incorrectly).
All that said, most folks get around 20 years for a gas furnace, 10-12 years for a heat pump, and 12-15 years for an air conditioner before having to replace it. Of course, that is assuming your install or house is not completely screwed up.
