What is the difference between Amana and Goodman?
Amana and Goodman are sister brands. Both are made by Daikin Comfort Technologies North America, a subsidiary of Daikin Industries, at the Daikin Texas Technology Park in Waller, Texas. The Amana name itself is licensed from Maytag, which is why you will see it on refrigerators too. The two lines share engineering, a factory and many parts. If you are weighing an Amana quote against a Goodman quote, you are mostly comparing a few hardware details, the warranty paperwork and the contractor.
Do Amana and Goodman sell the same models?
The lineups mirror each other almost model for model. Goodman's variable-speed inverter air conditioners are the GXV9S and GXV6S. Amana's are the AXV9S and AXV6S in its S-Series. Both brands have single-stage and two-stage models below that, and both build current air conditioners and heat pumps on R-32 refrigerant, the same as their sister brand Daikin. If you have an older R-410A system from either brand, it can still be repaired and recharged.
On the furnace side, both sell 80% and 90%-plus models from single-stage up to modulating with variable-speed blowers. More on each brand is on our Amana and Goodman pages.
How is an Amana furnace different from a Goodman inside?
The clearest physical difference is inside the furnace. Amana uses a stainless steel tubular primary heat exchanger. Goodman uses an aluminized steel tubular primary heat exchanger, paired with a stainless secondary on its condensing models.
Stainless holds up better against corrosion, and that matters in a Minnesota furnace that runs a lot of hours every winter. But the metal is not the whole story. A lot of the heat exchanger damage we find on any brand comes from overheating: a clogged filter, undersized return ducts or a furnace too big for the house that short-cycles all winter. Our guide to cracked heat exchanger symptoms explains what that looks like and why it is a carbon monoxide concern. A correctly sized Goodman with good airflow will outlast an oversized Amana.
The warranty gap got smaller in 2025
For years the headline difference was Amana's lifetime unit replacement warranty. If a covered major part failed, the original registered owner got a new unit for as long as they owned the home. That changed. For Amana equipment built after April 2025, the standard registered coverage is 10 years on parts and a one-time 10-year unit replacement on qualifying models. Lifetime-style coverage moved to Amana's optional Asure extended service plan, which you buy separately.
Goodman's registered coverage is 10 years on parts, with a 10-year unit replacement limited warranty on select models, including its variable-speed GXV9S. Goodman also offers Asure extended plans. Both brands require online registration within 60 days of installation.
So if an old review or an older quote tells you Amana comes with a lifetime compressor warranty, check the certificate for the exact model you are being quoted. If your existing Amana was installed and registered before the change, that earlier coverage still stands for you as the original owner. Neither brand's standard coverage pays the labor to swap a unit, which is one reason our installs add a 2-year labor warranty.
Is Amana more expensive than Goodman?
Amana is positioned as the step-up badge, and its quotes tend to run a bit higher than Goodman for the same staging, though the contractor sets the final number. Goodman is widely available to contractors, which is part of why you see so much of it. Price gaps between two quotes still come mostly from the contractor and the scope of work: the coil, the venting, the thermostat and the permit.
What matters more in a Minnesota basement
Since these two are so close, the install decides the outcome. We size replacements with a Manual J load calculation instead of copying the old nameplate, check duct static pressure and plan the venting before we quote. Our furnace installation page walks through that process. Installed prices in our area run roughly $4,500–$6,000 for an 80% AFUE furnace and $6,500–$9,500 for a 96–98% AFUE furnace, and $5,200–$9,800 for central AC. Our furnace replacement cost guide breaks down what moves the number.
We service and repair both brands. If yours is not keeping up, a service call is a $79 trip charge, waived when you approve the repair. Call 612-429-3465.
Questions
Does Amana still have a lifetime warranty?
Not as standard coverage on new equipment. For Amana products built after April 2025, the standard registered coverage is 10 years on parts and a one-time 10-year unit replacement on qualifying models. Lifetime-style unit and compressor coverage moved to Amana's optional Asure extended service plan. If your Amana was installed and registered earlier, check your certificate; earlier lifetime coverage for the original owner still applies.
Is a stainless steel heat exchanger worth paying more for?
It is a real hardware difference. Stainless resists corrosion better than aluminized steel, and a furnace in a Minnesota basement runs a lot of hours. That said, many cracked heat exchangers we find trace back to overheating from restricted airflow, oversizing or short cycling. A clean filter and a correctly sized furnace protect the heat exchanger more than the metal does.
Are Amana and Goodman parts interchangeable?
Many are, since both come off the same factory campus and share engineering. Motors, igniters, flame sensors and many boards overlap between equivalent models. Each brand still has its own model and part numbers, so we order by the nameplate. For you, it means repair parts for either are usually easy to get.
Do I need to register my Amana or Goodman equipment?
Yes. Both require online registration within 60 days of installation for the 10-year coverage, except in a few states. Miss it and coverage drops to the base terms, typically 5 years on parts. We register the equipment we install, but it is worth confirming you received the registration certificate.
Do you repair Amana and Goodman furnaces and ACs?
Yes, both brands. A service call is a $79 trip charge, waived when you approve the repair, and you get a written, flat-rate price before any work starts. We are open 7 days a week, 7am to 9pm. Call 612-429-3465.
