Carrier Performance 25 24k R-454B 208/230V 4-Zone Mini-Split
The Carrier Performance 25 4-Zone 24k (37MGRAQ24DA3) steps up to four indoor heads on one 208/230V outdoor unit, dealer-quoted through Carrier's installer network rather than sold as buyable equipment. It carries a certified nominal SEER2 of 25, EER2 13.5, and HSPF2 9.5, is ENERGY STAR certified and AHRI cold-climate designated, on current low-GWP R-454B refrigerant.
Cooling is rated at 24000 BTU, with heating of 25000 BTU at 47F, 23600 at 17F, and 18000 at 5F. Heating stays strong through 17F before tapering at 5F.
Professional installation required.

Frequently asked questions
- Can I install the Carrier Performance 25 4-Zone 24,000 BTU R-454B 208/230V (37MGRAQ24DA3) myself, or do I need a pro?
- Carrier Performance 25 4-Zone 24,000 BTU R-454B 208/230V (37MGRAQ24DA3) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
- Will the Carrier Performance 25 4-Zone 24,000 BTU R-454B 208/230V (37MGRAQ24DA3) keep heating in a cold winter?
- The manufacturer publishes 18,000 BTU/h of heating output at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 9.5 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
- What electrical circuit does the Carrier Performance 25 4-Zone 24,000 BTU R-454B 208/230V (37MGRAQ24DA3) need?
- Published electrical requirements: 230 V voltage, 23 A minimum circuit ampacity, and 25 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
- How far can the outdoor unit be from the indoor head?
- The published maximum line-set length is 262.5 ft, and the included line set comes pre-charged for 24.6 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
- What warranty does the Carrier Performance 25 4-Zone 24,000 BTU R-454B 208/230V (37MGRAQ24DA3) carry?
- The manufacturer publishes these warranty tiers: Standard: 10 yr parts / no separate compressor term (Consumer Choice 10-year parts-only option). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
