Goodman has built its reputation on a simple promise: dependable heating and cooling at a price real families can afford. Backed by Daikin — one of the largest HVAC manufacturers in the world — Goodman’s heat pump lineup has quietly become one of the strongest value plays in residential HVAC. And with the industry’s transition to next-generation refrigerant now behind us, the 2026 Goodman heat pump family runs on R-32 from top to bottom.
But the lineup spans everything from a straightforward single-stage unit to a variable-speed inverter system rated up to 21 SEER2, and the model codes (GLZS4B? GZV9S?) don’t exactly explain themselves. This guide walks through every current Goodman heat pump tier, what the ratings actually mean for your utility bill, how to size the system, and how to decide which model is the right fit for your home and climate.

Why Choose a Goodman Heat Pump?
A heat pump is the only piece of HVAC equipment that both cools and heats your home — it runs like a normal air conditioner in summer, then reverses in winter to pull heat from outdoor air and move it inside. Because it moves heat rather than generating it, a heat pump can deliver two to three units of heat for every unit of electricity it consumes, which is why heat pumps have become the default recommendation for so many homes, especially anywhere electric resistance heat or propane would otherwise be the alternative.
Within the heat pump market, Goodman occupies the value sweet spot. Since Daikin acquired Goodman in 2012, the brand has benefited from Daikin’s engineering and manufacturing scale — most Goodman equipment is built at the enormous Daikin Texas Technology Park near Houston — while keeping the no-frills pricing that made the brand famous. If you want a deeper dive on how the two brands relate, read our comparison: Goodman vs. Daikin 2026: Same Parent Company, Two Very Different Systems.
The short version: Goodman heat pumps are simple, widely supported, easy to get parts for, and priced well below premium brands with comparable efficiency ratings. That combination is hard to beat.
The 2026 Goodman Heat Pump Lineup at a Glance
Every current Goodman split-system heat pump uses R-32 refrigerant, the low-GWP (global warming potential) refrigerant Daikin standardized on across its brands as the industry moved away from R-410A. (Curious how R-32 compares to the other new refrigerant, R-454B? See our guide: R-32 vs. R-454B: Which New HVAC Refrigerant Is Better?)
Here is the current family, from entry level to flagship:
- GLZS4B — single-stage, up to 15.2 SEER2 and up to 7.8 HSPF2. The workhorse.
- GLZS5B — high-efficiency single-stage, up to 16 SEER2 and up to 8.2 HSPF2.
- GLZT7C — two-stage, up to 17.5 SEER2 and 8.2 HSPF2, with communicating ComfortBridge technology.
- GZV6S / GZV7S — side-discharge, variable-speed inverter models, up to 19 SEER2 and 8.8 HSPF2.
- GZV9S — the flagship variable-speed inverter heat pump, rated up to 21 SEER2.
Note that “up to” matters: the exact SEER2 and HSPF2 you achieve depends on the tonnage you choose and the indoor coil or air handler the outdoor unit is matched with. A 2-ton match often rates higher than a 5-ton match within the same series. Always check the AHRI-matched rating for your specific combination before you buy — it’s what determines the numbers on your paperwork.
Model-by-Model Breakdown
GLZS4B: The Value Workhorse
The GLZS4B is the entry point to the lineup and the model most homeowners in moderate climates actually need. It pairs a single-stage compressor with a straightforward control board, a factory-installed filter drier, and a galvanized steel cabinet. Ratings run up to 15.2 SEER2 and up to 7.8 HSPF2 depending on the match — comfortably above the federal minimum efficiency standards. Because it’s the simplest machine in the family, it’s also the least expensive to buy, the least expensive to repair, and the easiest for any technician in the country to service. If your priority is reliable comfort per dollar, start here.
GLZS5B: A Little More Efficiency, Same Simplicity
The GLZS5B is essentially the GLZS4B’s higher-efficiency sibling: still a single-stage design, but rated up to 16 SEER2 and up to 8.2 HSPF2. The bump in HSPF2 is worth noting for anyone in a heating-dominated climate — that’s the rating that describes winter efficiency, and it’s where a heat pump earns its keep. For homeowners who want lower operating costs without paying for staged or inverter technology, this is the sweet spot.
GLZT7C: Two-Stage Comfort and Communicating Controls
The GLZT7C steps up to a two-stage Copeland scroll compressor, which means the system can run at a lower capacity most of the time and reserve full output for the hottest and coldest days. Longer, gentler run cycles translate into steadier temperatures, better humidity removal in summer, and quieter operation. It’s rated up to 17.5 SEER2 and 8.2 HSPF2, has earned ENERGY STAR Most Efficient recognition, and features Goodman’s ComfortBridge communicating technology, which coordinates the outdoor unit and indoor equipment automatically and lets technicians commission and diagnose the system from a phone app via Bluetooth. If you’ve ever felt your current system blast on, overshoot, and shut off — this tier is the fix.
GZV6S and GZV7S: Side-Discharge Inverter Models
These two are a different shape of machine, literally. Instead of the traditional cube that blows air out the top, the GZV6S and GZV7S are slim, side-discharge units that hug the wall — a design Daikin pioneered for its FIT system. They’re a great answer for zero-lot-line homes, narrow side yards, and anywhere a traditional condenser won’t fit or would sit under a deck. Both use variable-speed inverter compressors rated up to 19 SEER2 and an excellent 8.8 HSPF2, ramping output up and down smoothly to match your home’s load rather than cycling on and off.
GZV9S: The Flagship
At the top of the lineup, the GZV9S is Goodman’s premium variable-speed inverter heat pump, rated up to 21 SEER2. This is the model for homeowners who want near-premium-brand efficiency and comfort — whisper-quiet modulation, precise temperature control, strong part-load performance — while staying inside Goodman’s value pricing. Paired with a matched variable-speed air handler, it delivers the kind of steady, even comfort that makes people forget their HVAC system exists.
Single-Stage vs. Two-Stage vs. Inverter: Which Tier Is Worth It?
The honest answer depends on three things: your climate, your utility rates, and how long you’ll stay in the home.
Single-stage (GLZS4B, GLZS5B) makes sense for moderate climates, rental properties, budget-driven replacements, and homes where the ductwork or insulation would limit what a premium system could deliver anyway. You give up some comfort refinement, not reliability.
Two-stage (GLZT7C) is the comfort upgrade with the most sensible payback for many families: noticeably better humidity control and temperature stability for a moderate price premium.
Inverter (GZV6S, GZV7S, GZV9S) is worth it when you run your system a lot — long cooling seasons, serious heating loads, high electric rates — or when comfort and quiet are top priorities. Inverter systems also shine in heating because they can adjust output as outdoor temperatures fall.

Sizing: Get the Tonnage Right Before Anything Else
No model choice matters more than correct sizing. An oversized heat pump short-cycles — it blasts to temperature and shuts off before it can dehumidify in summer or run efficiently in winter, wearing out components in the process. An undersized unit runs constantly and leans too hard on backup heat. Square footage alone is not enough to size a system; insulation, windows, ceiling height, ductwork, and your local climate all move the number.
Start with our free HVAC System Sizing Tool to get an estimate for your home, and for a larger project consider having a load calculation (Manual J) performed. When in doubt between two sizes on a heat pump, resist the old habit of rounding up — modern equipment performs best when it’s matched closely to the real load.
Cold-Climate Performance and Backup Heat
Can a Goodman heat pump handle a real winter? In most of the country, yes — with the right design. Every heat pump loses capacity as outdoor temperatures fall, which is why systems in colder regions are designed around a balance point: the outdoor temperature below which supplemental heat makes up the difference. In an all-electric home that usually means electric heat kit strips in the air handler; in a home with a gas line it can mean a dual fuel setup (more on that below).
The inverter models hold their capacity better in cold weather than single-stage units, which makes them the stronger choice as you move north. For the full picture — balance points, backup sizing, and what to expect at single-digit temperatures — read our guide: Cold-Climate Heat Pumps 2026.
Matching Indoor Equipment and Dual Fuel Options
A heat pump is only half the system. Outdoors you have the condenser; indoors you need either an air handler with an electric heat kit or, for dual fuel, a gas furnace with a matched coil.
Air handler + heat kit: The standard all-electric configuration. The air handler moves air and houses the coil; the heat kit provides emergency and supplemental heat. Choose a variable-speed air handler with the higher-tier heat pumps to unlock their full comfort and efficiency ratings.
Dual fuel: Pairing a heat pump with a gas furnace lets the system heat with the cheaper fuel automatically — the heat pump handles mild and moderate weather, and the furnace takes over when it’s cold enough that gas wins. Goodman’s furnace lineup pairs naturally with these heat pumps; see our Goodman Gas Furnace Guide 2026 and our full dual fuel guide for how the economics shake out.
Whichever configuration you choose, buy the outdoor unit, indoor unit, and coil as an AHRI-matched system. The match is what guarantees your rated efficiency and keeps your warranty coverage clean.
Warranty and Registration
Goodman’s heat pumps carry one of the better standard warranties in the value segment: a limited parts warranty of up to 10 years for registered residential installations. The key word is registered — take the few minutes to register your equipment online promptly after installation, because unregistered units revert to a shorter base coverage period. Keep your AHRI certificate and installation paperwork with the registration; if you ever need a warranty part, having those on hand makes the claim painless. Also remember that parts warranties don’t cover labor, which is one more reason a quality installation matters as much as the box you buy. Our guide to reading an HVAC quote covers what to look for.
Installation Notes for the R-32 Era
For contractors — and homeowners who want to understand what their installer is doing — a few things are different with the current R-32 lineup than with the R-410A equipment it replaced. R-32 is classified as a mildly flammable (A2L) refrigerant, so current equipment ships with A2L-compliant components and installations follow updated handling, brazing, and leak-detection practices. Recovery machines, gauges, and detectors need to be A2L-rated. None of this is exotic anymore — A2L refrigerants are now the industry norm — but it does mean working from the installation manual rather than from old habits. If you’re weighing whether to keep repairing an aging R-410A system or move to current equipment, our guide Still Running an R-410A System in 2026? walks through that decision.
Technicians can find A2L-ready meters, gauges, and leak detection equipment in our Tools department, along with line sets, pads, disconnects, and everything else for a clean install in Parts & Supplies.

Frequently Asked Questions
Is Goodman a good heat pump brand?
Yes — particularly on value. Goodman equipment is built by Daikin, uses widely available parts, and carries a strong registered parts warranty. You’re trading some premium refinement at the entry tiers, not reliability. Our honest take is here: Is Goodman a Good AC Brand?
What refrigerant do 2026 Goodman heat pumps use?
The current lineup uses R-32, a lower-GWP A2L refrigerant that replaced R-410A across the industry. Existing R-410A systems can still be serviced, but new Goodman equipment is R-32.
Which Goodman heat pump is best for a cold climate?
The variable-speed inverter models (GZV6S, GZV7S, GZV9S) hold their heating capacity best as temperatures drop. In any cold climate, plan the balance point and backup heat as part of the design rather than an afterthought.
Can I replace just the outdoor unit?
Usually not a good idea — and with the refrigerant change, an old R-410A indoor coil is not compatible with a new R-32 outdoor unit. Replace the system as an AHRI-matched pair to get rated efficiency, proper operation, and full warranty coverage.
Bottom line: from the budget-friendly GLZS4B to the flagship GZV9S, the 2026 Goodman heat pump lineup covers nearly every home, climate, and budget — and every model in it shares the same DNA of simple, serviceable, Daikin-backed engineering. Figure out your size, pick your comfort tier, match the indoor equipment, and you’ll have a system that quietly does its job for the next decade and beyond.
