Goodman 3.5 Ton 15.2 SEER2 Heat Pump System with Multi-Positional Air Handler (R-32)
This Goodman stands out among the ducted options for pairing 3.5-ton capacity with a 15.2 SEER2 rating and an air handler that can be installed upflow or horizontally. That flexibility can simplify fitting the system to an existing mechanical space. Its 9-speed ECM blower offers more airflow adjustment than a basic fixed-speed setup, though the compressor is not inverter-driven, so it will not modulate output as precisely as a variable-speed system such as the MRCOOL DIY Select.
The R-32 refrigerant and corrosion-resistant aluminum coil add practical appeal, but this is not a complete answer for every installation: heat and downflow kits are separate, and professional installation is required for warranty eligibility. I rank it ahead of the smaller Goodman 3-ton system when a home needs the extra capacity, while buyers should confirm sizing with an HVAC contractor rather than choose by tonnage alone.
Pros:- 15.2 SEER2 efficiency with R-32 refrigerant
- Upflow and left- or right-horizontal air-handler configurations
- 9-speed ECM blower allows more airflow adjustment
- Corrosion-resistant aluminum coil
Cons:- No inverter compressor for variable-capacity operation
- Heat kit and downflow kit are sold separately
- Warranty requires qualified professional installation and registration
Best for: Homeowners replacing a ducted system who need 3.5-ton capacity and an air handler that can fit an upflow or horizontal installation.
Not ideal for: Buyers seeking inverter-driven temperature modulation or a ready-to-install package with every required kit included.
- Capacity:3.5 tons (42,000 BTU)
- Efficiency:15.2 SEER2
- Refrigerant:R-32
- Compressor:Rotary scroll
- Blower motor:Direct-drive, 9-speed ECM
- Air-handler configurations:Upflow, horizontal right, horizontal left
- Voltage:240V
- Warranty:10-year parts warranty with registration
Our verdict“Choose this Goodman if you need a flexible 3.5-ton ducted system and value its efficiency and installation orientations over inverter modulation.”
Goodman 3-Ton 15 SEER2 R-32 Heat Pump System with Air Handler
For a ducted home that does not call for 3.5 tons, this Goodman provides a 36,000 BTU split system with both the outdoor heat pump and air handler included. Its 15 SEER2 rating and R-32 refrigerant put it close to the larger Goodman 3.5-ton system, but the smaller capacity may suit a properly sized mid-size home better. Capacity should still be confirmed through a load calculation; a lower tonnage is not automatically the better fit.
The main buying wrinkle is accessory compatibility. You will need a compatible HKSC or HKSX heat kit, and line sets and thermostats are separate; HKR-series kits are not supported. Compared with the MRCOOL DIY Select, this is a conventional central system for existing ductwork, not a DIY-friendly single-zone solution. Its listed outdoor noise level and substantial system weight also call for careful site planning.
Pros:- Heat pump and multi-position air handler are included
- 36,000 BTU capacity for a correctly sized mid-size home
- R-32 refrigerant and 15 SEER2 efficiency
- Compatible with HKSC and HKSX heat kits

Our verdict“Pick this system for a properly sized, ducted mid-size home if its heat-kit requirements and separate accessories fit your installation plan.”
MRCOOL DIY Select 24,000 BTU Mini-Split Heat Pump, 230V
The MRCOOL DIY Select serves a different buyer from either Goodman central system: it is a single-zone ductless heat pump with a pre-charged Quick Connect line set intended to make installation more accessible without refrigerant handling. For a garage, addition, or other separated space, app and voice controls and inverter operation offer more room-level control than a conventional ducted setup. Its listed quiet mode, starting at 21.5 dB(A), is another advantage for spaces where indoor noise matters.
Its 24,000 BTU capacity is specified for areas up to 1,050 square feet, but that does not make it a whole-home replacement for the 3-ton Goodman system. It also needs 230V power, and the supplied data lists a two-year warranty. Compared with the Temprium 24,000 BTU mini-split, this model has a smaller stated coverage area but offers the Quick Connect DIY installation approach.
Pros:- Pre-charged Quick Connect line set supports DIY-oriented installation

- Controls:App, voice, and remote
- Warranty:2 years
Our verdict“Choose the MRCOOL for one space where DIY-oriented installation and quiet, app-controlled operation matter more than whole-home coverage.”
Temprium 24,000 BTU Mini-Split Air Conditioner and Heat Pump, 230V, 19 SEER2
The Temprium’s main distinction in this group is its stated coverage up to 1,500 square feet from a 24,000 BTU ductless system, paired with inverter operation and a 19 SEER2 rating. That makes it an option for buyers comparing room-sized mini-splits who want app and voice control, multiple operating modes, and a washable filter. The high-temperature self-cleaning function adds a maintenance feature not listed for the MRCOOL DIY Select.
Its heating specification needs careful attention: operation is stated down to 5°F, so it may be a poor match for a home that depends on the mini-split during colder winter conditions. The one-year warranty is shorter than the MRCOOL’s listed two years, and unlike that model, this listing does not describe a pre-charged Quick Connect installation system. Treat the area figure as a guide, not a substitute for proper sizing and climate planning.
Pros:- 19 SEER2 rating with inverter operation
- Listed coverage up to 1,500 square feet
- App, voice, and remote controls with several operating modes
- Washable filter and high-temperature self-cleaning function

Goodman GPH1442H41 3.5 Ton 14 SEER Packaged Heat Pump
Unlike the split systems elsewhere in this lineup, the Goodman GPH1442H41 puts its heating and cooling components in a single packaged unit. That can suit a property where a rooftop or ground-level installation is preferable to separate indoor and outdoor equipment. Its 3.5-ton, 42,000 BTU capacity lines up with the Goodman 3.5 Ton 15.2 SEER2 split system, but this package is rated at 14 SEER and uses R-410A rather than R-32.
The galvanized-steel cabinet has a UV-resistant finish, and the listed 10-year parts and compressor warranty may appeal to buyers seeking a packaged format with long component coverage. The tradeoff is the 400-pound unit, which complicates transport and placement, plus the electric heat kit is a field option rather than included. It also uses a single-circuit design, limiting zoning flexibility compared with a multi-zone arrangement.

How We Picked
To determine the best EVI heat pumps, I evaluated each model based on its Seasonal Energy Efficiency Ratio (SEER2) and Heating Seasonal Performance Factor (HSPF2), which directly correlate to long-term operating costs. I prioritized systems using R-32 refrigerant, as this is the current industry standard for efficiency and environmental compliance. Build quality and warranty support were also critical factors, given that heat pumps are major home investments requiring long-term reliability.
The ranking logic favors models that offer a balance of high efficiency and practical installation requirements. For instance, while packaged units are convenient for specific home layouts, they generally rank lower than split systems due to noise and slightly lower efficiency ceilings. I also weighted the availability of integrated smart thermostats and inverter technology, which allow for variable-speed operation and better temperature maintenance.
Factors to Consider When Choosing Best EVI Heat Pumps
Selecting the right heat pump involves more than just picking the highest efficiency rating. You must match the unit’s capabilities to your home’s insulation, climate zone, and existing infrastructure. This guide breaks down the key factors that influence your decision.Understanding SEER2 and HSPF2 Ratings
The transition from SEER to SEER2 represents a stricter testing methodology that reflects real-world operating conditions more accurately. A higher SEER2 number means the unit uses less electricity to produce the same amount of cooling, directly lowering your summer bills. Similarly, HSPF2 measures heating efficiency, which is the most important metric for EVI (Enhanced Vapor Injection) heat pumps in cold climates. When comparing models, look for a minimum of 15 SEER2 and 7.5 HSPF2 for a modern, efficient system. Do not be misled by older marketing materials that still use the old SEER scale, as these units may perform differently under the new standards.
The Impact of R-32 Refrigerant
Refrigerant type has shifted toward R-32, which offers a higher heat transfer efficiency and a lower Global Warming Potential than the previously dominant R-410A. This change means newer R-32 systems are generally more efficient and compliant with upcoming environmental regulations. However, R-32 is mildly flammable, requiring specific handling procedures during installation and maintenance. This might slightly increase labor costs if your HVAC technician is not yet certified for R-32 handling. Ensure your installer is trained in R-32 protocols to avoid safety hazards and warranty issues.
DIY Mini-Splits vs. Professional Central Systems
DIY mini-split heat pumps like the MRCOOL series eliminate the need for expensive licensed HVAC contractors, saving thousands in labor costs. These systems come pre-charged with refrigerant in the line sets, allowing homeowners to connect indoor and outdoor units without special tools. However, they are typically limited to zone heating and cooling, meaning you need multiple indoor units to cover an entire house. Central ducted systems, while requiring professional installation, offer seamless whole-home climate control and often integrate better with existing smart home ecosystems. Choose DIY for additions, garages, or specific rooms, and central systems for main living areas.
Sizing and Capacity for Cold Climates
Correct sizing is critical; an undersized unit will struggle to maintain temperature during extreme cold snaps, while an oversized unit will short-cycle, reducing efficiency and wear. For EVI heat pumps, check the low-temperature capacity curves provided by the manufacturer. These charts show how much BTU output remains at temperatures like 5°F or -13°F. Many standard heat pumps lose up to 40% of their capacity at freezing temperatures, whereas true EVI models maintain closer to 80-90%. Never rely solely on the square footage rule of thumb; consult a Manual J calculation for accurate load requirements.
Noise Levels and Placement Constraints
Outdoor unit noise can be a nuisance if placed near bedroom windows or neighboring properties. Look for models with variable-speed compressors and fan motors, as they operate much more quietly than single-stage units. Packaged units, which combine all components in one box, often generate more noise because the compressor and fan are in the same enclosure. If noise is a concern, prioritize split systems where the noisy compressor can be placed away from living spaces. Additionally, check local ordinances regarding decibel limits for outdoor HVAC equipment to avoid compliance issues.
Frequently Asked Questions
Do EVI heat pumps require a backup heat source in very cold climates?
While EVI technology significantly improves low-temperature performance, it does not eliminate the need for backup heat in extreme climates. Most EVI units are rated to operate down to -13°F or -22°F, but their capacity drops as temperatures fall. In regions where temperatures frequently stay below 0°F for extended periods, a hybrid system with a gas furnace or electric resistance heat kit is recommended. This ensures you have reliable heating capacity when the heat pump’s output is at its lowest.Can I install a DIY mini-split heat pump myself if I have no HVAC experience?
Yes, systems like the MRCOOL DIY line are specifically designed for homeowners with no professional HVAC certification. They come with pre-charged line sets and quick-connect fittings that eliminate the need for vacuum pumps or refrigerant gauges. However, you still need to mount the indoor unit, drill through the wall, and run electrical wiring, which requires basic handyman skills and adherence to local electrical codes. If you are uncomfortable with electrical work or structural modifications, hiring a licensed electrician for the final connections is a wise safety precaution.Is the R-32 refrigerant more dangerous than older types?
R-32 is classified as A2L, meaning it is mildly flammable under high concentrations and high temperatures. Under normal operating conditions in a sealed system, it is safe and poses no risk to occupants. The danger only arises during improper installation or repair, where a large leak could ignite if exposed to an open flame. Technicians must be trained in R-32 handling procedures, which differ slightly from non-flammable refrigerants. Always ensure your installer is certified for R-32 to guarantee safe system integrity.How does SEER2 differ from the old SEER rating?
SEER2 uses a new test procedure (ASHRAE 16-2020) that includes higher external static pressure and more realistic operating conditions than the old SEER test. This means a unit rated 16 SEER2 is roughly equivalent to 14-15 SEER under the old standard. You cannot directly compare a SEER2 rating to an old SEER rating without conversion. The new metric is more representative of actual energy consumption in homes with ductwork resistance, making it a more reliable indicator of real-world efficiency.Are packaged heat pumps less efficient than split systems?
Generally, yes. Packaged units house the compressor, fan, and coil in a single outdoor cabinet, which often leads to higher noise levels and slightly lower efficiency due to shorter refrigerant lines but less optimized airflow. Split systems allow the indoor air handler to be placed in conditioned space, reducing duct losses and improving efficiency. However, packaged units are an excellent choice for homes without basements or crawl spaces where installing a split system’s indoor unit would be impossible or prohibitively expensive.Conclusion
