Key Takeaways
- The lineup spans two different jobs: eight ductless mini-splits suit individual zones or open areas, while the two Goodman systems pair a condenser with an air handler for ducted heating and cooling.
- Goodman’s 14.3 SEER2 R-32 system leads for whole-home buyers because its newer refrigerant and included air handler make it a more current system package than the 14 SEER Goodman option.
- MRCOOL’s 115V DIY model stands apart on installation approach; it may suit homeowners seeking a less conventional install, but electrical and local code requirements still need professional attention.
- Capacity and electrical service narrow the shortlist quickly: the 12,000 BTU options are not interchangeable with the 18,000 BTU ROVSUN or 24,000 BTU Senville, and voltage requirements vary.
- SEER2 figures alone do not identify the right pick: the listed mini-splits range from 19 to 22 SEER2, but room load, cold-weather performance, installation quality, and service support also shape real-world fit.

More Details on Our Top Picks
ROVSUN 18000 BTU WiFi Enabled Mini Split Air Conditioner & Heater with Inverter
The ROVSUN pairs 18,000 BTU heating and cooling with a 20 SEER2 inverter, making it a stronger fit for a broad open area than the 12,000 BTU Mountman or COSTWAY. Its listed coverage reaches 1,000 square feet, though actual performance depends on insulation, layout, and climate. App and voice control add convenient temperature changes without relying on the remote, while the 32 dB mute setting is a useful advantage for a living space where indoor noise matters. The tradeoff is that capacity and smart features do not make installation simple: this is a split system, and professional HVAC setup is recommended. The included 16.4-foot copper line set helps with placement, but the required power cord is not included, so buyers should check electrical and installation needs before choosing it.
Pros:- 18,000 BTU heating and cooling suits larger spaces than the 12,000 BTU options in this lineup.
- 20 SEER2 inverter operation is designed to reduce energy use.
- App, remote, Alexa, and Google Assistant controls offer flexible operation.
- 32 dB mute mode and 16.4-foot copper line set add convenience.
Cons:- Professional HVAC installation adds complexity and may require separate labor.
- Power cord is not included.
- Its larger capacity may be unnecessary for smaller, well-contained rooms.
Best for: Owners of a larger, open living area who want higher capacity, app control, and both heating and cooling from one ductless system.
Not ideal for: DIY-focused buyers or anyone seeking a complete plug-and-play package; professional installation is recommended and a power cord is not included.
- Cooling capacity:18,000 BTU
- Heating capacity:18,000 BTU

Our verdict“Choose the ROVSUN for a larger room that needs more capacity than the 12,000 BTU picks, provided you are prepared for professional installation.”
Senville LETO Mini Split Air Conditioner Heat Pump – White, 24,000 BTU
At 24,000 BTU, the Senville LETO is the capacity pick in this group, aimed at medium to large spaces that may outgrow the 12,000 BTU Mountman, COSTWAY, or Temprium. Its DC inverter and Alexa/app controls bring the convenience of a smart ductless system, while heating, cooling, dehumidifying, and air circulation cover more than temperature adjustment alone. The listed 34 dB noise level is quiet, though it is above the ROVSUN’s 32 dB mute figure and well above the Temprium’s 23 dB claim. The main tradeoff is the installation commitment: the product calls for professional setup, and labor is not covered by its five-year parts and compressor warranty. I would choose it for a larger zone, not a smaller room where its added capacity may be unnecessary.
Pros:- 24,000 BTU capacity exceeds the output of the other listed mini-splits.
- DC inverter supports efficient operation as demand changes.
- App and Alexa controls accompany remote operation.
- Five-year parts and compressor warranty is specified.
Cons:- Professional installation is required, and labor is excluded from the warranty.
- The 34 dB listed noise level is higher than the ROVSUN and Temprium figures.
- High capacity may be excessive for smaller rooms.
Best for: Homeowners or light-commercial buyers who need a high-capacity wall-mounted system for a medium-to-large room or open area.
Not ideal for: Buyers heating or cooling a compact room, or those who need installation labor included in warranty coverage.

Our verdict“Pick the Senville LETO when a large space needs substantially more output than the 12,000 BTU systems can provide.”
Mountman 12,000 BTU Mini-Split Air Conditioner and Heat Pump
The Mountman is a 12,000 BTU, 115-volt option for buyers who want heating and cooling in a single room without stepping up to the ROVSUN’s larger 18,000 BTU capacity. Its 19 SEER rating, 26 dB noise claim, and straightforward remote-and-timer controls make it a practical feature set for a bedroom or smaller living area. Sleep, ECO, and turbo modes let buyers tailor operation, while the washable filter, self-cleaning function, and automatic defrost reduce some routine upkeep. Compared with the Wi-Fi-equipped COSTWAY and Temprium, this Mountman listing does not specify app or voice control, so it is less suited to buyers who want smart-home access. Coverage is also inconsistent: the product information gives both 600 and 750 square feet, and installation-kit details are absent.
Pros:- 115-volt supply distinguishes it from higher-voltage options such as the ROVSUN.
- Includes heating, cooling, dry, and fan modes.
- Washable filter, self-cleaning, and automatic defrost support routine upkeep.

Our verdict“Choose the Mountman for a modest 115-volt room setup if basic controls suit you and you can confirm coverage and installation details before purchase.”
COSTWAY 12,000 BTU Mini Split Air Conditioner and Heat Pump, 20 SEER2, 115V
The COSTWAY stands out among the 12,000 BTU choices for its stated heating operation down to -4°F, a useful distinction for buyers in colder areas. It also lists cooling operation up to 127°F, Wi-Fi and voice controls, and 20 SEER2 inverter performance. Against the Mountman, it offers clearer smart-home features and a stated 750-square-foot coverage area; against the quieter Temprium, its noise figure starts at 28 dB rather than 23 dB. Eight fan speeds and washable filters add flexibility, but this is still a split system, not a replacement that avoids installation work: professional installation is recommended, and a new outdoor unit is required. The listed 115-volt supply may suit some homes, but buyers should confirm the circuit and installation requirements with a qualified installer.
Pros:- Listed heating operation extends down to -4°F.
- 20 SEER2 inverter rating and Wi-Fi, Alexa, and Google Assistant controls.
- Eight fan speeds provide more adjustment than a basic low/medium/high setup.
- Includes a 16.4-foot copper connection pipe and washable filters.
Cons:- Professional installation is recommended.
- Requires a new outdoor unit.
- At 28 dB minimum, it is not as quiet on paper as the Temprium’s 23 dB listing.
Best for: Homeowners in colder regions seeking a 12,000 BTU ductless system with a stated low-temperature heating range and smart controls.
Not ideal for: Buyers looking for a DIY-ready replacement or the quietest listed 12,000 BTU option; professional installation is recommended, and the Temprium lists a lower noise level.

12,000 BTU Mini Split Air Conditioner with 22 SEER2, 115V Heat Pump
The Temprium is the most bedroom-oriented of the 12,000 BTU models here, with a listed 23 dB noise level and 22 SEER2 efficiency. That combination gives it a clear paper advantage over the Mountman’s 26 dB and 19 SEER listing, and the COSTWAY’s 28 dB and 20 SEER2 figures. Its 12,300 BTU heating output is slightly above its 12,000 BTU cooling capacity, while Wi-Fi, Alexa, Google Assistant, and Follow-Me add useful control options for a room where comfort needs change through the day. Self-cleaning and a washable filter help with basic maintenance. The compromise is installation flexibility: this split system requires a dedicated 115-volt outdoor unit and cannot retrofit an existing system. Its listed one-year warranty is also shorter than the Senville’s stated five-year parts and compressor coverage.
Pros:- 23 dB listed noise level is the lowest among the 12,000 BTU products in this batch.
- 22 SEER2 inverter efficiency is higher than the COSTWAY’s 20 SEER2 listing.

MRCOOL 12,000 BTU 115V DIY Ductless Mini-Split Heat Pump, 5th Generation
The MRCOOL stands apart from the Tehanld and COSTWAY options because it includes a 25-foot pre-charged quick-connect line set and is designed for DIY installation. That can make it a better fit for a homeowner who wants a ductless system without the usual refrigerant-line connection work, though careful setup still matters. Its 12,000 BTU capacity is listed for spaces up to 550 square feet, a more restrained coverage target than Tehanld’s 750-square-foot claim. The 23.5 SEER rating, inverter operation, and app and voice controls add useful efficiency and convenience for year-round heating and cooling. The tradeoff is a substantial listed system weight of 120 pounds, and DIY-friendly does not mean the installation is effortless or suitable for every home.
Pros:- Pre-charged 25-foot quick-connect line set is designed to simplify installation.
- Heating and cooling support year-round room comfort.
- 23.5 SEER rating and inverter operation support efficient variable output.
- App, remote, and voice controls offer flexible operation.

Tehanld Mini Split AC/Heating System – 12,000 BTU, 19 SEER2, 115 V Heat Pump, up to 750 sq ft, Complete Installation Kit
The Tehanld’s main distinction is its stated coverage of up to 750 square feet from a 12,000 BTU system, making it a candidate for larger rooms than the MRCOOL, which is listed for up to 550 square feet. Its 19 SEER2 rating, inverter compressor, and 42 dB noise level pair efficiency-minded operation with a quieter listed sound level than MRCOOL’s 45 dB. Five operating modes, three fixed fan speeds plus auto, and a 24-hour timer offer practical control without relying on the app and voice features found on MRCOOL. The central drawback is installation: this system requires a professional, so the included kit does not make it a DIY project. It also ships in two packages that may arrive separately, which can delay a planned installation.
Pros:- Listed coverage reaches up to 750 square feet.
- Inverter technology adjusts compressor output rather than relying only on fixed operation.
- 42 dB listed noise level with sleep and eco modes.
- Five modes and a 24-hour programmable timer provide flexible scheduling.

Our verdict“Pick the Tehanld for a professionally installed 12,000 BTU system when its broad stated coverage and timer matter more than DIY setup.”
COSTWAY 12,000 BTU Mini-Split Air Conditioner and Heater
The COSTWAY makes its case with a 23 dB listed noise level, well below the Tehanld’s 42 dB and MRCOOL’s 45 dB figures. That makes it the standout here for a bedroom or other space where indoor sound matters. It also combines heating, cooling, dry, and fan modes with 20 SEER2 efficiency, a washable filter, and self-cleaning and auto-defrost functions. Compared with MRCOOL, it does not offer the same stated DIY-oriented quick-connect line set; a licensed HVAC installer is required, and the description notes a compatible outdoor unit is needed. Its 68-pound listed weight is much lower than MRCOOL’s 120 pounds, though weight alone does not resolve installation requirements. The 750-square-foot coverage is a manufacturer-listed target, so room layout and climate still affect fit.
Pros:- 23 dB listed noise level is the quietest among these five options.
- 20 SEER2 rating with inverter technology.
- Washable filter and self-cleaning and auto-defrost functions support routine upkeep.
- Remote includes a timer and automatically dimming display.

Our verdict“Choose this COSTWAY if low listed operating noise and built-in maintenance features are priorities and professional installation is acceptable.”
Goodman 2 Ton 14.3 SEER2 Multi-Position R-32 Heat Pump System with Air Handler (GLZS4BA2410 Condenser and AMST24BU1300 Air Handler)
Unlike the MRCOOL, Tehanld, and COSTWAY ductless units, this Goodman pairs a 24,000 BTU condenser with a multi-position air handler, making it the more relevant choice when replacing or building a ducted central system rather than conditioning one room. Its 230 V power requirement and 2-ton capacity place it in a different installation category from the 115 V, 12,000 BTU mini-splits. A registered 10-year parts warranty is a useful ownership feature when installed by a qualified professional, and the factory-installed filter drier and corrosion-resistant aluminum air-handler construction support a conventional system setup. The tradeoffs are its non-inverter design and 74 dB listed noise level; it lacks the variable compressor operation and quieter indoor-unit figures offered by the mini-splits. A heat kit for colder climates is sold separately.
Pros:- 24,000 BTU, 2-ton capacity suits a central-system replacement rather than one-room conditioning.
- Multi-position air handler can accommodate different installation orientations.
- Factory-installed filter drier and corrosion-resistant aluminum construction are practical system features.
- Registered 10-year parts warranty is available with qualified professional installation.
Cons:- Non-inverter operation lacks the variable-speed adjustment offered by the mini-split options.
- A separate heat kit is needed for colder climates.
- The listed 74 dB noise level is much higher than the listed indoor-unit levels of the mini-splits.
Best for: Homeowners replacing a ducted central system who need a 2-ton heat pump and can use qualified professional installation.
Not ideal for: Buyers heating a single room, seeking a ductless DIY system, or needing a variable-speed inverter compressor or included cold-climate heat kit.
- Capacity:2 tons
- Cooling power:24,000 BTU
- SEER:14.3 (15.2 reported)
- Voltage:230 V
- Refrigerant:R-32
- Noise level:74 dB
- Compressor:Rotary/scroll
- Inverter:No
- Warranty:10-year parts warranty when registered and professionally installed
Our verdict“Choose this Goodman for a professionally installed ducted 2-ton replacement, not for a single-room ductless heating and cooling project.”
Goodman 2-Ton 14 SEER Heat Pump System with Multi-Position Air Handler
This Goodman is another ducted 2-ton system, not a room-by-room mini-split like the MRCOOL or COSTWAY. Its listed 24,000 BTU capacity, multi-position air handler, pre-charged system, service valves, and gauge ports make it a practical package for a qualified installer handling a central-system project. The product description cites a 15.2 SEER rating, while the title calls it a 14 SEER system; buyers should verify the exact rating and equipment match before purchase. Compared with the other Goodman in this group, it shares the GLZS4BA2410 condenser and AMST24BU1300 air handler model number but presents a different efficiency claim. Neither Goodman has inverter operation, so they offer less variable compressor control than the three mini-splits. A separate heat kit is needed in colder climates.
Pros:- 24,000 BTU, 2-ton capacity is suited to central-system applications.
- Multi-position air handler offers installation flexibility.
- Pre-charged system includes service valves and gauge ports.
- Limited 10-year parts warranty is available with qualified installation.
Cons:- No inverter technology for variable-speed compressor operation.
- Separate heat kit is required for cold-climate use.

Best for: Homeowners replacing a ducted central heat pump who want a pre-charged 2-ton system for professional installation.
Not ideal for: Buyers who need a ductless system, inverter-driven output, or a heat kit included for colder-weather operation.
- Capacity:2 tons
- Cooling power:24,000 BTU
- SEER:15.2 listed in description; 14 SEER in title
- Voltage:240 V
- Refrigerant:R-32
- Noise level:74 dB
- Compressor:Scroll
- Inverter:No
- Warranty:10-year limited parts warranty with qualified installation
Our verdict“Consider this Goodman for a professionally installed central-system replacement after confirming its applicable efficiency rating and cold-weather heat-kit needs.”
How We Picked
I grouped these products by the job they are designed to do: ductless mini-splits for room-by-room heating and cooling, and Goodman systems for homes with ductwork. I compared stated capacity, voltage, efficiency information, included system components, and installation approach. Those details affect whether a unit can fit the space and electrical service, how much work the project may involve, and whether the product is a room solution or a whole-home replacement.
The ranking favors clear use cases and practical fit over a single headline specification. Goodman’s 14.3 SEER2 R-32 package ranks highest for whole-home shoppers, while MRCOOL earns a distinct place for its DIY-oriented format and ROVSUN for higher capacity among the listed ductless units. The remaining mini-splits are differentiated by capacity, voltage, and stated efficiency; products with sparse model detail rank lower because buyers have less information to confirm compatibility. I would still verify heating output at local winter temperatures, warranty terms, installer requirements, and certification before purchase.
Factors to Consider When Choosing Best Home Heat Pumps
Choosing among these heat pumps starts with the home rather than the product list. I would settle the system type, heating load, electrical constraints, and installation plan before comparing efficiency numbers. These checks can prevent a unit that looks suitable on paper from being poorly matched to the rooms or climate it needs to serve.
Choose Ductless or Ducted Before Comparing Models
A ductless mini-split delivers heating and cooling to one or more indoor zones, so it can be a practical fit for additions, converted garages, or homes without ducts. A ducted system connects to an air handler and distributes conditioned air through existing ductwork, making it a different kind of project from installing a wall-mounted head. Do not assume a single mini-split will heat or cool a whole home just because its capacity sounds substantial. Check whether the listed system includes the indoor components you need and whether your existing ducts are in usable condition. New ductwork can change the project scope, while leaky ducts can undermine a replacement system. Pick the distribution method first; then compare products within that category.
Size by Heating and Cooling Load, Not Floor Area Alone
BTU capacity is a starting point, not a room-size guarantee. Insulation, ceiling height, window area, air leakage, sun exposure, and local design temperatures all affect how much heating or cooling a space needs. Oversizing can lead to short cycles and uneven comfort, while undersizing may leave a room struggling during extreme weather. The Tehanld listing gives a floor-area claim, but that kind of estimate should not replace a load calculation for your home. Ask a qualified contractor for a room-by-room Manual J calculation when the system will serve a large or irregular space. That step is especially useful when comparing the 12,000 BTU models with the 18,000 BTU ROVSUN and 24,000 BTU Senville.
Check Cold-Weather Heating Performance
A heat pump’s heating capacity can fall as outdoor temperatures drop, and products with similar nominal BTU figures may behave differently in cold conditions. Look for published heating capacity and operating limits at temperatures that reflect your winters, rather than relying only on cooling capacity or SEER2. If those figures are missing, ask the manufacturer or installer for the performance data before committing. In colder regions, a backup heat source may be part of the plan, adding equipment and operating considerations. Also check whether the home’s insulation and electrical service can support the chosen system. Matching the unit to local winter conditions matters more than choosing the highest efficiency number in isolation.
Confirm Voltage, Breaker, and Installation Requirements
The listings include both 115V and 230V mini-splits, so electrical compatibility can immediately rule out some choices. Have an electrician confirm the circuit, breaker, wire size, disconnect, and local permit requirements before ordering. A pre-charged line set or installation kit does not automatically make a system a safe or code-compliant DIY project. Refrigerant handling, line-set length limits, pressure testing, and commissioning can affect performance and warranty coverage. MRCOOL’s DIY-oriented format may reduce some installation barriers, but it does not remove every electrical or code requirement. Get written confirmation of who can install the unit and keep the warranty valid.
Treat Efficiency Ratings as One Part of Running Cost
SEER2 describes seasonal cooling efficiency, so it cannot by itself tell you how efficiently a heat pump will heat your home in winter. The listed mini-splits include ratings from 19 to 22 SEER2, but a higher figure does not guarantee lower bills if the unit is oversized, poorly installed, or used in a challenging climate. Compare heating performance data and, where available, HSPF2 alongside the cooling rating. Your electricity rate, thermostat habits, and how much of the home the system serves also influence operating costs. I would compare complete performance data for the specific model rather than relying on a product title. A careful installation and sensible sizing can matter as much as a small gap in the published rating.
Check Service, Warranty, and Parts Before Buying
Heat pumps are long-term equipment, so access to trained service and replacement parts should influence the purchase. Confirm the warranty length, registration steps, labor coverage, and any requirement for professional installation; these terms can differ from the headline product description. Ask local HVAC contractors whether they will install and service the exact model, especially for lesser-known mini-split brands. A system that is difficult to support can become inconvenient even if its specifications look appealing. For Goodman ducted systems, confirm the air handler and condenser pairing, refrigerant compatibility, and any required accessories with the installer. Keep the model and serial information, installation documents, and commissioning records together.
Frequently Asked Questions
Can a 12,000 BTU mini-split heat and cool my whole house?
Usually, a 12,000 BTU single-zone unit is intended to condition a defined area, not automatically an entire house. Open floor plans may allow air to reach several connected rooms, but closed doors, long hallways, and separate floors limit distribution. A load calculation should account for insulation, windows, climate, and how the rooms connect. If you want whole-home coverage, compare a properly sized ducted system or a multi-zone design with individual indoor units. Do not rely on a broad square-foot claim without checking the conditions behind it.
Should I choose a 115V or 230V mini-split?
Choose based on the specific unit’s electrical requirements and the circuits available at your home, not on a general assumption that one voltage is better. A 115V model can be easier to accommodate in some homes, but it still may need a dedicated circuit and correct breaker and wiring. A 230V unit requires compatible service and installation. Have an electrician verify the panel capacity and installation details before ordering. Voltage compatibility is only one check; confirm capacity, local code, and warranty conditions as well.
Is a DIY mini-split a good choice if I have never installed HVAC equipment?
A DIY-oriented product can simplify parts of installation, but it does not make every part of the job beginner-friendly. Electrical work, mounting, condensate drainage, line-set routing, and local permits still require care, and mistakes can affect safety, performance, or warranty coverage. Ask the manufacturer which tasks a homeowner may perform and whether commissioning must be handled by a licensed professional. Check local rules before starting, since requirements vary by location. If you are unsure about any connection or refrigerant-related step, arrange professional installation instead.
Are these mini-splits suitable as the only heat source in a cold climate?
That depends on the exact model’s low-temperature operating range and heating capacity, not simply its advertised BTU rating. Request performance tables showing output at outdoor temperatures typical of your winters, and compare them with your home’s calculated heat loss. Some homes may need backup heat during the coldest periods even when a heat pump handles most of the season. If a listing does not provide cold-weather data, ask the manufacturer or an HVAC contractor before treating it as a sole heat source. A backup plan should be part of the design rather than an afterthought.
Can I replace an existing heat pump with a Goodman system without changing my ducts?
Possibly, but a matching capacity does not guarantee that a new condenser and air handler will work well with existing ducts. An installer should check duct condition, airflow, static pressure, electrical connections, refrigerant line compatibility, and the exact indoor-outdoor pairing. A duct system designed for a different airflow may need adjustments for proper operation. Ask for a load calculation and a written scope that identifies any required duct or accessory changes. Confirm the specific Goodman model combination and warranty terms before approving the replacement.
Conclusion
For a whole-home replacement, I would start with the Goodman 2 Ton 14.3 SEER2 R-32 system, provided the air handler, ducts, and home load are a match. The best value direction among the ductless options is a 12,000 BTU model chosen only after checking its electrical needs, full performance data, and local support; the lineup does not provide enough detail to name one clear value leader on efficiency alone. For a premium whole-home choice, the Goodman R-32 package is the strongest fit here, while buyers should compare its installation scope and service terms before purchase. Beginners considering ductless should look first at the MRCOOL DIY-oriented model but still confirm permits, warranty rules, and professional help for electrical or commissioning work. For a larger single zone, compare the ROVSUN 18,000 BTU and Senville 24,000 BTU against a load calculation; for a smaller area, a 12,000 BTU option may be more appropriate. My final recommendation is to confirm system type, sizing, winter output, and installer support before choosing by headline efficiency or capacity.
