Goodman has quietly become one of the most popular air conditioner brands in America, and it’s not hard to see why: solid engineering backed by parent company Daikin, straightforward warranties, and pricing that consistently undercuts the premium brands. But the lineup changed significantly with the industry-wide refrigerant transition, and if you’re shopping for a Goodman AC in 2026, you’re looking at a completely different set of model numbers than you would have seen just a couple of years ago.
This guide walks through the full 2026 Goodman central air conditioner lineup — from the budget-friendly GLXS3B to the top-of-the-line GXV9S inverter system — and explains what the tiers actually mean for your comfort and your utility bill. It rounds out our Goodman series alongside the Goodman heat pump guide, the gas furnace guide, and the air handler guide.

Why Goodman? A Quick Brand Overview
Goodman was founded in Houston in 1982 with a simple pitch: build dependable equipment without the premium-brand markup. In 2012, the company was acquired by Daikin, the largest HVAC manufacturer in the world, and today Goodman equipment is built in Daikin’s massive Texas manufacturing campus. That parentage matters — Goodman’s newest inverter-driven models borrow heavily from Daikin’s variable-speed compressor technology, which has been refined over decades in markets around the globe.
The value proposition is straightforward: you get much of the engineering of a premium system at a mid-market price, with one of the more generous standard warranties in the industry. For a deeper dive on reliability and how the brand stacks up, see our honest review of Goodman as an AC brand and our Goodman vs. Daikin comparison.
The R-32 Refrigerant Transition: What Changed
As of January 1, 2025, new residential air conditioners can no longer be manufactured with R-410A refrigerant. Manufacturers had to pick one of two lower-GWP (global warming potential) replacements, and the Daikin family — Goodman included — chose R-32, while many competitors went with R-454B. R-32 is a single-component refrigerant, which makes it easier to charge and recover, and it has been used in millions of systems worldwide for over a decade.
Practically, this means every current Goodman air conditioner is an R-32 unit, and the model numbers now start with “GLX” or “GXV” instead of the old “GSX” prefixes. An R-32 condenser must be paired with an R-32-rated indoor coil and line set components — you cannot simply bolt a new condenser onto an old R-410A coil. If you want the full technical background on the two new refrigerants, our R-32 vs. R-454B comparison covers it in detail, and if you’re nursing along an older R-410A system, our guide on running an R-410A system in 2026 explains the repair-vs-replace math.
The 2026 Goodman AC Lineup, Tier by Tier
Goodman’s current split-system air conditioner family spans seven models across three broad tiers. Efficiency ratings below are “up to” figures from Goodman’s published literature — the exact SEER2 you achieve depends on tonnage and which indoor coil or air handler you pair with the condenser.
Entry Tier: GLXS3B and GLXS4B (Single-Stage)
These are the workhorses of the lineup — traditional “cube” condensers with single-stage compressors that run at 100% capacity whenever cooling is called for.
The GLXS3B (up to 15 SEER2, depending on size and match) is the entry point: a rotary compressor on the smaller 1.5–2.5 ton sizes and a scroll compressor on 3–5 ton units, a 10-year parts limited warranty, and the lowest price of any current Goodman AC. It’s a strong choice for rental properties, budget-conscious replacements in moderate climates, and anyone who wants simple, proven cooling. Note that the lowest-efficiency ratings in this family only meet the federal minimum in northern states — more on regional rules below.
The GLXS4B (up to 15.2 SEER2) steps efficiency up a notch with the same single-stage simplicity. For many homeowners this is the sweet spot between purchase price and operating cost, and its ratings clear the stricter Southeast and Southwest minimums in common configurations — though you should always verify the certified rating of your exact condenser-plus-coil combination before buying.
Mid Tier: GLXS4M and GLXS5B (High-Efficiency Single-Stage)
The GLXS4M (up to 15.2 SEER2) and GLXS5B (up to 16.5 SEER2) use more efficient scroll compressors and coil designs to squeeze more cooling out of every kilowatt. The GLXS5B is the efficiency leader among Goodman’s single-stage cubes, and in hot climates where the AC runs five-plus months a year, the energy savings over an entry-tier unit add up year after year. These remain single-stage machines, so they’re best for homeowners who want lower bills without paying for staging or inverter technology.
Two-Stage: GLXT7C
The GLXT7C (up to 17.2 SEER2) adds a two-stage compressor that can run at a reduced capacity for most of the day and ramp to full output only when needed. The payoff is longer, gentler run cycles: steadier temperatures, better humidity removal, and quieter operation, helped by a factory sound blanket on the compressor. If you’ve read our guide to single-stage vs. two-stage vs. variable-speed systems, the GLXT7C is the classic middle path — a meaningful comfort upgrade without inverter-tier pricing.
Inverter Tier: GXV6S and GXV9S (Side-Discharge Variable-Speed)
At the top of the lineup sit two side-discharge inverter units that look and behave very differently from a traditional cube. Instead of blowing air out the top, they exhaust horizontally from a slim, low-profile cabinet that tucks neatly against a wall, under a deck, or into a zero-lot-line side yard.
The GXV6S (up to 17.2 SEER2) and the flagship GXV9S (up to 19.0 SEER2) use variable-speed swing compressors that continuously modulate output to match your home’s load. Rather than slamming on at 100% and shutting off, they glide along at partial capacity for hours at a time — which translates into very quiet operation, excellent humidity control, and the lowest operating costs in the lineup. These models also carry Goodman’s strongest warranty package, covered in the warranty section below. If the side-discharge concept sounds familiar, it’s the same format Daikin pioneered with the Daikin Fit — we covered it in our Daikin Fit explainer — brought to the Goodman badge at a Goodman price.
SEER2 Ratings and Regional Minimums
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling output per unit of electricity over a simulated season, using a more realistic test procedure than the old SEER metric. Higher is better, and as a rough rule of thumb, moving from a 14-class unit to a 17-class unit cuts cooling energy use meaningfully — how meaningfully depends on your climate, your electric rate, and how long your cooling season runs.
Two things trip up AC shoppers here. First, federal minimums are regional: since 2023, new central air conditioners under 45,000 BTU must meet 13.4 SEER2 in the North but 14.3 SEER2 in the Southeast and Southwest. If you live in a southern state, the lowest-rated configurations of the entry tier cannot legally be installed in your region, so check the certified rating for your specific condenser-and-coil match. Second, the rating belongs to the matched system, not the condenser alone — the same GLXS4B condenser can certify at different SEER2 values depending on the coil, furnace, or air handler it’s paired with. Our full explainer on SEER2, EER2, and HSPF2 breaks down how much efficiency is actually worth paying for.
One note on incentives: the federal 25C tax credit that helped offset high-efficiency AC purchases expired at the end of 2025, but many state and utility rebate programs are still active in 2026. See our 2026 tax credits and rebates guide for what’s still on the table, and check your local utility before you buy.
Matching Your Condenser to a Coil, Air Handler, or Furnace
A central air conditioner is only half of a system. The outdoor condenser must be matched with one of the following indoors:
- A cased evaporator coil sitting on top of a gas furnace, which handles both heating and the blower function — see our Goodman gas furnace guide for the furnace side of that equation.
- An air handler with a built-in blower and optional electric heat kit, common in all-electric homes — our Goodman air handler guide walks through the AMST and AMVT families and heat kit sizing.
Three matching rules matter in 2026. The refrigerant must match — R-32 condenser, R-32-rated coil. The capacity must match — a 3-ton condenser needs a coil rated for 3 tons. And the technology should match — the inverter-driven GXV models deliver their comfort and efficiency benefits when paired with the communicating, variable-speed indoor equipment Goodman specifies for them, so follow the manufacturer’s approved match list rather than mixing and matching. The AHRI certificate for your combination is the document that proves the pairing and protects your warranty and any rebate claims.
How to Choose the Right Model
Start with sizing, not SEER2. An oversized air conditioner short-cycles: it cools the air quickly but shuts off before wringing out humidity, leaving the house cold and clammy while hammering the compressor with starts and stops. An undersized unit runs forever and never catches up on the hottest days. Square footage alone isn’t enough — insulation, windows, orientation, and climate all matter. Our free HVAC system sizing tool gives you a solid starting estimate, and our guide on how to size your heating and air conditioner explains the Manual J logic behind it.
Then match the tier to your situation:
- Short cooling season, tight budget, or rental property: GLXS3B or GLXS4B. Single-stage cooling has worked for decades, and the money saved up front may never be recouped through efficiency in a northern climate.
- Long, hot cooling season: GLXS5B at minimum. When the AC runs from April through October, the efficiency gap between tiers shows up on every monthly bill.
- Humidity complaints or uneven temperatures: GLXT7C two-stage. Longer run cycles at lower capacity are the fix for muggy, up-and-down comfort.
- Tight lot lines, noise concerns, or maximum efficiency: GXV6S or GXV9S. The slim side-discharge cabinet solves placement problems, and inverter modulation delivers the quietest, most even cooling Goodman makes.
And one timing note: if your current system is limping, don’t wait for a June heat wave to replace it. As we covered in our shoulder-season buying guide, fall and winter are the smartest time to buy an air conditioner — equipment availability is better, installers have open calendars, and you’re not negotiating from a 95-degree house.
Warranty: What’s Covered and the Registration Step You Can’t Skip
Every current Goodman air conditioner carries a 10-year parts limited warranty for registered units. The top of the lineup goes further: per Goodman’s published literature, the GXV9S, GXV6S, and GLXT7C add a 10-year unit replacement limited warranty (if the compressor fails in the first decade, you can get a whole new unit rather than just a part) plus a one-time compressor replacement provision that extends beyond year ten.
The catch: registration. The extended coverage terms require online registration, generally within 60 days of installation (some states, such as California and Florida, have rules that make registration unnecessary there). Unregistered units in most states revert to a shorter base warranty. Registration takes ten minutes on Goodman’s website — do it the week your system goes in. Also keep your installation paperwork and AHRI certificate; warranty claims and labor coverage questions go much smoother with documentation in hand. For the bigger picture on what voids coverage, our HVAC warranty guide is worth a read before you buy any brand.
