Homeowner’s Guide to Carrier’s Best Mini Splits

 A ductless mini split buyer’s guide helps homeowners evaluate seven key factors: system type, number of zones, BTU capacity, SEER2 and HSPF2 efficiency, Carrier series and features, installation requirements, and total budget.

Before choosing a ductless mini split, consider:

• System type: Decide whether you need cooling only or a heat pump that provides both heating and cooling.
• Zones: Choose a single-zone system for one room or a multi-zone system for multiple rooms or areas.
• BTU capacity: Match the system’s heating and cooling capacity to the size, layout, insulation, windows, and climate of the space.
• Efficiency: Compare SEER2 for cooling and HSPF2 for heating to understand seasonal energy performance.
• Features and tier: Compare Carrier Infinity®, Performance™ and Comfort™ Series based on efficiency, controls, heating performance, and available features.
• Installation: Account for indoor-unit placement, refrigerant-line length, electrical requirements, outdoor-unit location, and professional commissioning.
• Budget: Carrier estimates professionally installed ductless mini split systems typically cost about $2,500 to $15,000 or more, depending on the number of zones, efficiency, equipment, and installation complexity.

Carrier’s ductless mini split systems use inverter technology to adjust heating and cooling output based on demand. Depending on the model, Carrier systems can provide high-efficiency cooling, heating in cold outdoor temperatures, and independently controlled comfort by zone.

Use the guide below to narrow your options, then have a local Carrier expert Carrier dealer perform a professional load calculation and recommend a properly matched system for your home. Ask your local Carrier dealer about financing plans available that can help make your purchase more manageable with convenient monthly payments.

Carrier’s 7-Step Mini Split Selection Framework

Choosing a mini split starts with the space you want to condition, not a particular model. Use these seven steps to compare systems before requesting an installation quote.

The right mini split is the one whose capacity, efficiency, configuration, features, and installation requirements match the space being conditioned—not necessarily the system with the highest efficiency rating or largest capacity.

Carrier Mini Split Series: Infinity®, Performance™ and Comfort™

Carrier offers ductless systems across three series: Infinity®, Performance™ and Comfort™. When comparing them, look beyond the series name and evaluate the specific model's SEER2, HSPF2, heating performance, sound rating, controls, indoor-unit options, and other available features.

For example, Carrier's Infinity® 35 37MPRA heat pump is rated up to 35.1 SEER2 and 30 HSPF2, while the Performance™ 25 37MGRA is rated up to 25.2 SEER2 and 10.4 HSPF2. The Comfort™ 22 37MHRAQ is rated up to 22.4 SEER2 and 9.4 HSPF2. Actual performance depends on the specific matched system configuration.

Infinity® Series (Premium Performance)

Carrier’s Infinity® line represents the top tier of ductless innovation, designed for homeowners who want the highest level of energy efficiency and comfort. These systems feature advanced inverter technology that continuously adjusts output to maintain precise temperatures, resulting in ultra-quiet operation and minimal energy waste. Infinity® systems are ideal for whole-home zoning or high-demand areas where consistent climate control is critical.

Casey McAllister, Vice President of Comfort Now By Bob McAllister in Egg Harbor Township, New Jersey, explains why his company recommends the Carrier Infinity® Series for homeowners looking for high-efficiency ductless heating and cooling.

“We pretty much exclusively sell the Infinity line at our company,” McAllister said. “The system’s high efficiency is a major selling point because it gives us confidence that homeowners are getting the efficiency and performance they’re looking for. With a modulating Carrier Infinity system, I’m confident I’m getting the performance I’m asking for.

“For us, another big advantage is the combination of utility incentives and financing programs that can make these systems more accessible to homeowners. Homeowners are increasingly looking for highly efficient electric heating and cooling solutions. The Infinity system checks a lot of those boxes.”

Performance™ Series (Balanced Value & Features)

The Performance™ series is the versatile “workhorse” of Carrier’s ductless lineup, offering a strong balance between upfront cost and advanced functionality. With up to a 25.2 SEER2 cooling efficiency rating and a 10.4 HSPF2 heating efficiency rating, Performance Series mini splits can help lower heating and cooling bills and reduce your carbon footprint. These systems can automatically adjust operation based on real-time conditions, delivering efficient heating and cooling. It’s a popular choice for homeowners who want dependable performance and high efficiency.

Comfort™ Series (Reliable & Budget-Friendly)

For those looking for a more economical option, the Comfort™ series provides a straightforward path to Carrier reliability. While it doesn’t include all the high-end features of the other tiers, it still delivers efficient zoned comfort and typically outperforms traditional window units or older central systems in both comfort and energy efficiency.

Beyond choosing the right series, professional mini split installation—especially proper air handler placement—is critical. Unlike DIY systems, your local Carrier expert will position indoor units for optimal airflow, efficiency, and coverage, avoiding common issues like hot and cold spots, poor circulation, or reduced system lifespan.
