Picking the wrong size combo unit means you either shiver through January or pay sky-high electric bills every month — but actually matching the tonnage to your square footage changes everything. This article cuts straight through the language of SEER2 ratings (a newer efficiency score that accounts for real ductwork), R-32 refrigerants (a refrigerant with lower environmental impact), and split-system (two pieces) vs. packaged (one box) forms so you know exactly which Goodman unit fits your home and your budget — without wasting a penny on capacity you do not need.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every unit here handles both winter heating and summer cooling, and the full breakdown below reveals which model won’t leave you cold. Whether you are outfitting a small ranch or a sprawling open-plan house, you can use this comparison to find the right combination heating and air conditioning units with confidence.
Our Picks at a Glance
How To Choose The Best Combination Heating And Air Conditioning Units
You are about to make a multi-thousand-dollar purchase that will heat and cool your home for the next decade or more. The three specs that matter most are on the spec sheet: the tonnage (capacity), the SEER2 rating (efficiency), and the type of system (split-system or packaged). Getting these right determines whether your home actually feels comfortable and whether your energy bills stay reasonable.
Match Tonnage to Your Home Size
Tonnage measures the unit’s cooling power in British Thermal Units (BTUs) — 1 ton equals 12,000 BTUs. A 2-ton unit is good for around 1,000-1,200 square feet, while a 5-ton unit might be right for 2,500-3,000 square feet. Undersize the unit and it runs constantly without ever reaching the thermostat setting — oversize and it short-cycles, leaving your home clammy and wasting energy. Stick with the tonnage that matches your home’s square footage and local climate.
Look at SEER2, Not Just SEER
SEER2 is the newer, tougher federal efficiency rating for heat pumps and air conditioners — it replaces the older SEER standard with a more realistic test cycle that accounts for how duct systems actually perform. A unit with a higher SEER2 rating, like 15.2, uses less electricity to deliver the same amount of cooling compared to a unit rated at 14.5. Over a decade of use, the difference adds up to noticeable savings.
Split-System vs. Packaged Unit
You have two main physical setups. A split-system uses an outdoor condenser (the heat pump part) and an indoor air handler (the part that blows air into your ducts) — the two pieces communicate via refrigerant lines. This is the most common setup for homes with an existing furnace or closet space. A packaged unit squeezes everything into a single metal box that sits on a slab next to the foundation — it is simpler and often used when indoor space is tight or you are replacing an existing packaged system.
The Refrigerant Matters: R-32
R-32 is a newer, more environmentally friendly refrigerant with a much lower global warming potential (a measure of its heat-trapping effect in the atmosphere) than the older R-410A. Some Goodman systems in this list already use R-32, which means they meet or exceed upcoming federal regulations and generally perform better in extreme temperatures. If you want to future-proof your purchase and avoid future conversion costs, prioritize units that already run on R-32.

In‑Depth Reviews
1. Goodman 5 TON 14.5 SEER2 Multi-Position R-32 Heat Pump System with air handler
The powerhouse for large homes that cuts future compliance worries with R-32 refrigerant.
This system pairs the 5 Ton 14.5 SEER2 Heat Pump GLZS4BA6010 with the AMST60DU1300 air handler to produce a fu the entire heat pump system — compressor, coil, and blower — lives inside a single gray metal enclosure. That means you do not need to find indoor space for a separate air handler, and installation is essentially a one-day job: set the slab, connect the ducts, and wire the power.
This unit weighs 400 pounds and taps a single 1 circuit power source. The factory installed bi-flow liquid line filter dryer (a device that keeps moisture and dirt out of the refrigerant) is already on board, which protects the system from debris during operation. The permanently lubricated motor condenser fan requires no oiling, so maintenance stays low. The louvered protection cupboard around the coil shields the fins from weather and yard debris without blocking airflow.
The 14.0 efficiency is standard for its size and means steady performance, not a record-breaking utility bill. One reviewer with a 1,800-square-foot home said the unit handled both a brutal summer and a below-freezing snap without a hiccup, which aligns with its strong rating.
Best for Simpler Installations: If you have a concrete pad next to your house and want a single-box heat pump that delivers comfort without a complicated two-piece setup, this package unit is the standout.
One Trade-Off: The 3.5-ton size fits medium-large homes well, but if your home is on the larger side you may want to look at the 5-ton options above — this unit cannot be expanded later.
2. Goodman 2.5 Ton 14 SEER Heat Pump GLZS4BA3010 with Air Handler
The mid-sized split system that is already running R-32 and earning praise from owners.
You get 30,000 British Thermal Units of cooling power from this 2.5-ton heat pump — a 25 percent increase over the 24,000 BTU offered by the 2-ton units on this list. That extra cooling makes it a better fit for moderately sized homes around 1,500 square feet where a 2-ton system might struggle on the hottest days. The unit also uses R-32 refrigerant, same as the top 5-ton pick, so you are future-proofed against the next regulatory shift.
The heat pump and the Multi-Position Air handler AMST30BU1300 arrive as a split system. The air handler uses corrosion-resistant aluminum tubing with grooved surfaces for better heat transfer — plus it passed rigorous helium pressure tests at the factory, which suggests a low risk of refrigerant leaks. The system is pre-charged for 15 feet of line length, so the installer’s job is simpler as long as the line set is within that range. At 303 pounds, this 2.5-ton system is noticeably lighter than the 400-pound 3.5-ton package unit, making it easier to move into place.
Owners mention the 10-year parts warranty as a major draw, but they also point out the same cold-climate note that applies to every split-system without a built-in heat kit — you will need to buy a separate heat kit if you live in a northern state. One buyer with a 1,400-square-foot home said the unit cycled quietly and kept every room at the set temperature, and that the 4.3 out of 5 star rating with 16 reviews reflects consistent satisfaction.
Why This Size Hits the balance
- 30,000 BTUs of cooling power beats 2-ton units by a clear 25% margin.
- R-32 refrigerant offers future-readiness at a mid-range price tier.
- Aluminum air handler with grooved tubing really does improve heat exchange efficiency.
Heads-Up for Cold-Climate Buyers
- No integrated heat kit — budget for an electric heat kit separately if you expect extended freezes.
Best For: A medium-sized home needing a 2.5-ton capacity with the refrigerant of the future and a lighter overall system weight that is easier to install.
skip it if: Your home is under 1,000 square feet — a 2-ton unit will cost less and cover you perfectly.
3. Goodman 2 Ton 15.2 SEER2 Heat Pump Split System GLZS4BA2410 AMST24BU1300
A 4.2-star rated 2-ton system with the scroll compressor (a quiet, durable compressor type) that HVAC techs trust.
You get 24,000 British Thermal Units of cooling power from this 2-ton split system, which is the standard entry point for a small to medium home. The system uses a scroll compressor — the same type of quiet, durable compressor found in the premium units above — and a multi-position air handler that works in upflow, horizontal right, or horizontal left configurations. That flexibility means your installer can route the ductwork in whatever direction your space allows.
The SEER2 rating is 15.2 for this specific unit, but the product listing itself is older and carries a 14 SEER label in the title — make sure to confirm the exact model when ordering. The factory-installed filter drier and the pre-charge for 15 feet of tubing both come standard, which keeps the installation process clean. The AHRI certificate number 215213871 is the same as the 15.2 SEER2 unit above, which confirms this pair’s tested efficiency.
At a 4.2 out of 5 star rating from 45 reviews, this is the most-reviewed unit in our list. Several owners say the scroll compressor runs quietly enough to sit beside the house without disturbing the patio. The main caution you will see in the data is that a heat kit is not included — you will want one if you live in a cold climate — and that the remote controller requires you to download the Goodman app for full control.
Why It Earns Its High Review Count
- 45 reviews with a 4.2 out of 5 star average suggest reliable real-world performance.
- Scroll compressor is known for quiet, consistent operation.
- Multi-position air handler fits almost any attic, basement, or closet layout.
Two Realities from the Data
- No heat kit included — budget extra for electric heat strips if you expect winter temps below freezing.
- The controller is app-based, so you need to be comfortable using a smartphone as the primary thermostat interface.
Reach For This If: You need a straightforward 2-ton split system with lots of owner feedback to back it up, and you plan to install it in a configuration where the air handler orientation matters.
Look at the 15.2 SEER2 Model Instead If: You want the highest efficiency rating at this size — spend a bit more upfront for the long-term energy savings.
4. Goodman 2 Ton 14 Seer 40,000 Btu 81% Afue Gas Package Air Conditioner GPG1424040M41
SEER2 vs SEER
SEER2 is the updated federal efficiency standard that replaces the older SEER rating. It uses a more demanding test procedure that accounts for the added resistance of real duct systems — which means SEER2 numbers are typically a little lower than SEER numbers for the same unit. A 14 SEER unit often scores 13.4 to 13.8 SEER2. Higher is better: a 15.2 SEER2 unit consumes noticeably less electricity than a 13.4 SEER2 unit over a whole cooling season.
Split-System vs. Packaged Unit
A split-system has two main pieces: an outdoor condenser (the heat pump) and an indoor air handler. The two are connected by refrigerant lines. This setup gives you more flexibility for placement and repairs but requires more installation labor. A packaged unit puts everything — compressor, coil, blower, and (in some designs) gas furnace — into one box. Installation is simpler and faster, but the whole unit sits outside and may be slightly less efficient due to shorter coil surface.
R-32 vs R-410A Refrigerant
R-32 is a single-component refrigerant with a global warming potential (GWP) roughly one-third that of R-410A. It is more efficient in extreme temperatures and is the refrigerant chosen by manufacturers for new high-efficiency systems. R-410A is still widely used and serviceable, but regulatory changes are gradually pushing the industry toward R-32 and other low-GWP blends. A unit that already uses R-32 is effectively buying you a longer service life before the next mandatory refrigerant transition.
