Check Price on Amazon

This is the only true 5-ton package unit in the lineup — a horizontal-discharge Goodman that slides directly onto an existing slab and ties into your ductwork with zero indoor equipment. The scroll compressor is R-410A ready and built for the long haul; owners report reliable operation after two years with heat strips only engaging when outdoor temps drop into the 30s. At 13.4 SEER2, it’s not the efficiency king, but for a straight-across replacement of an older 5-ton unit, the drop-in simplicity saves thousands in labor vs a split conversion.

The form factor is critical here — this is a low-profile horizontal package unit, not a vertical or mini-split. That means it fits where a 5-ton package unit already sits, but if your slab was poured for a vertical unit, you’ll need a new pad. Some buyers received units without the factory refrigerant charge or without heat strips installed, so verify those details upon delivery and plan for a professional startup. The 5-ton capacity is overkill for most homes under 2,500 sq ft, but for open-concept commercial spaces or large manufactured homes, the brute-force BTU delivery is unmatched.

Customer reports indicate the heat pump performs well in mild winters, but in regions below 30°F, auxiliary heat strips become necessary. One owner noted the unit tripped the breaker during extreme heat, suggesting the need for a correctly sized breaker and proper charge verification at startup. For a straightforward slab swap that prioritizes raw capacity over modulation, the Goodman GPHH36041 is the definitive choice.

At 3.5 tons, this Goodman package unit sits below the 5-ton range, but it deserves attention for buyers who need a reliable mid-range capacity with a proven track record. Owners report these units lasting decades in secondary structures like barns and woodworking shops, with one reviewer on their third Goodman in 41 years. The 14 SEER rating translates to roughly 13.4 SEER2 under the new test procedure, so expect solid but not spectacular energy savings compared to a 16+ SEER inverter system.

Installation is straightforward for a licensed tech — the package unit design means all connections are at the cabinet. Some buyers needed to modify or rebuild their existing curb because the footprint didn’t match older units, so measure your slab dimensions and duct offset before ordering. At 400 pounds, moving this unit requires a dolly and at least two people, but the all-in-one construction eliminates the need for an indoor air handler and refrigerant line runs.

The scroll compressor is the same reliable R-410A design Goodman has used for years, and the single-circuit electrical requirement simplifies wiring. For a shop, rental property, or home where 3.5 tons is sufficient (roughly 1,500–2,000 sq ft depending on insulation), this unit offers the lowest cost-per-BTU in the package-unit category. Just budget for a new curb if your existing one doesn’t match the GPH1442 footprint.

While not a package unit in form factor, this Cooper & Hunter 3-ton dual-zone mini-split delivers the raw 36,000 BTU capacity of a 5-ton heat pump in a much more flexible configuration. The inverter scroll compressor modulates between 12,000 and 36,000 BTU as needed, so you get the benefit of variable-speed efficiency without the energy spikes of a single-speed 5-ton unit. The 24 SEER2 rating — nearly double the Goodman package unit’s efficiency — translates to real monthly savings in heating-dominated climates.

The system ships with two wall-mounted indoor units (12K and 24K), two 25-ft installation kits, and two smart control modules. That means you can independently heat or cool a 1,500 sq ft main area and a 500 sq ft bedroom from one outdoor condenser. Owners report silent indoor operation and very low power consumption compared to window units or central AC. The catch: this is a mini-split, so it requires refrigerant line sets running from the outdoor unit to each indoor head, plus a condensate drain. Professional installation is mandatory to preserve the warranty.

Long-term reliability is a mixed bag. Some owners report flawless multi-year performance, while others experienced compressor or fan motor failures after five years, with costly repairs. The included smart control works well via app, but the voice control integration can be finicky. For buyers who want true zone control and premium efficiency over a slab-mounted package unit, this Cooper & Hunter is hard to beat — just budget for professional maintenance every six months to maximize lifespan.

At 28,000 BTU (2.3 tons), this Cooper & Hunter system is smaller than a true 5-ton package unit, but its 25 SEER2 rating makes it the efficiency leader in this comparison. The inverter compressor and dual-zone setup mean you can run a 9,000 BTU head in a small bedroom and an 18,000 BTU head in a main living area, each at its own temperature. For a well-insulated home under 1,500 sq ft, this system can replace a much larger single-speed unit while using a fraction of the electricity.

The 25-ft installation kits and smart control modules are included for both zones, and the outdoor condenser is pre-charged for up to 25 ft of line set. Owners praise the silent operation — both indoor and outdoor units are nearly inaudible — and the rapid cooling performance in hot climates. The downsides are typical of mini-splits: the remote control’s button layout is poorly designed (mode button sits too close to the up arrow), and there’s no room temperature display on the unit or remote itself. The directions are notably sparse, making professional installation a must unless you’re an experienced HVAC tech.

Reliability is a concern worth noting. One owner reported a complete outdoor unit failure (E1 error code) after two years, with no support from Cooper & Hunter’s customer service. Another buyer had three compressors and multiple wall units fail after five years. The efficiency is exceptional, but the longevity track record suggests this is a 5-7 year system rather than a 15-year investment. For a short-term upgrade or a secondary structure, the energy savings may still justify the purchase.

Senville markets this 36,000 BTU (3 ton) system as a “central air conditioner heat pump split system,” but it’s functionally a mini-split designed to tie into existing ductwork via a central air handler. The inverter-driven scroll compressor is rated to deliver heat down to -22°F, making it one of the best cold-climate performers in this list. For buyers in northern climates who need a 5-ton heat pump’s capacity but want modern inverter efficiency, this 3-ton unit can often satisfy a well-sealed 2,000 sq ft home without short-cycling.

The 16 SEER2 efficiency is decent for a non-package unit, and owners report real energy savings — one saw a 1,700 kWh reduction in the first month. The variable-speed compressor never fully turns off, instead modulating to maintain set temperature, which eliminates the temperature swings of single-speed units. However, the outdoor unit is physically massive, so confirm your installation location has enough clearance. The included 16-ft line set is often too short, and the 3/4″ flare connectors can be hard to source locally.

Customer support is a weak point. One owner reported a PC 04 error code after three months with no response from Senville after three hours on hold. The manuals are also notoriously poor, even for experienced HVAC techs — the wiring requires two separate 230V services and specific S1/S2 and HA/HB communication wires that aren’t clearly documented. For buyers willing to work through the installation complexity, the sub-zero heating performance is unmatched at this price tier, but factor in the potential for support headaches.

This single-zone Cooper & Hunter delivers 36,000 BTU (3 tons) through one wall-mounted indoor unit, making it an ideal solution for open-concept spaces like a 1,500 sq ft shop, garage, or great room. The 19.5 SEER2 rating and inverter technology provide strong efficiency, and the system can heat down to -13°F. The included 16-ft installation kit, smart control module, and pre-charged outdoor condenser simplify the professional install process, though the 16-ft line set may be too short for some placements.

Owners consistently praise the whisper-quiet operation — both indoor and outdoor units are nearly silent. One reviewer cools a 2,000 sq ft metal shop with 14-ft ceilings, maintaining a comfortable 82°F when outdoor temps exceed 100°F, and noted that the power bill increase was half of what they expected from a non-inverter unit. The smart app control works reliably, allowing remote temperature adjustments and scheduling.

The biggest limitation is the single-zone design — you can’t independently control different rooms. For a shop, garage, or open-plan living area, that’s fine. But if you need to cool separate bedrooms or partitioned spaces, you’ll need a multi-zone system. Some DIY-minded owners self-installed in about 10 hours, but the unit is shipped via freight and requires a professional for warranty compliance. The reported humidity control is excellent, making this a strong choice for humid southern climates where dehumidification is as important as cooling.

The DELLA 35,000 BTU (2.92 ton) dual-zone system is the entry-level multi-zone option, using the newer R-454B refrigerant that has a lower global warming potential than R-410A. The 19 SEER2 rating and DC inverter technology promise up to 30% power savings compared to older units. The system includes two indoor heads (12K and 24K BTU), two 16-ft installation kits, and smart control compatibility with Alexa and WiFi.

Performance is impressive for the price — one owner reported cooling a 1,000 sq ft space from 98°F to 70°F in under 30 minutes, with power bills cut by roughly 40% compared to four window units. The outdoor unit is extremely quiet at 36 dBa, and the indoor heads are barely audible at normal fan speeds. However, the included copper lines are thin and kinked easily during installation, and the manual warns that altering line-set length requires adjusting refrigerant levels — a tricky process for DIY installers.

Reliability is a gamble. While many owners report excellent performance, there are notable complaints about error codes on the display immediately after purchase, a compressor replacement that didn’t fix the issue, and poor tech support that sent confusing diagrams instead of practical help. The system also lacks the self-cleaning function that some competitors offer, even though the display shows the option. For cost-conscious buyers willing to work with a knowledgeable installer and accept some risk, the DELLA delivers impressive cooling capacity per dollar — but the support and build quality trail the premium brands.
