The Carrier Performance 25 5-Zone 36k (37MGRAQ36EA3) is the largest standard-tier condenser, feeding five indoor heads from 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 24, EER2 12, and HSPF2 9.5, is ENERGY STAR certified and AHRI cold-climate designated, on current low-GWP R-454B refrigerant.

Cooling is rated at 36000 BTU, with heating of 37000 BTU at 47F, 31000 at 17F, and 26000 at 5F. The extra capacity suits larger five-room layouts.

Professional installation required.

Frequently asked questions

Can I install the Carrier Performance 25 5-Zone 36,000 BTU R-454B 208/230V (37MGRAQ36EA3) myself, or do I need a pro?
Carrier Performance 25 5-Zone 36,000 BTU R-454B 208/230V (37MGRAQ36EA3) 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 5-Zone 36,000 BTU R-454B 208/230V (37MGRAQ36EA3) keep heating in a cold winter?
The AHRI/ENERGY STAR certification lists 26,000 BTU/h of heating capacity 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 5-Zone 36,000 BTU R-454B 208/230V (37MGRAQ36EA3) need?
Published electrical requirements: 230 V voltage, 30.5 A minimum circuit ampacity, and 35 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 from the outdoor unit to one indoor head is 114.8 ft. The combined piping limit across all heads is 262.5 ft. The outdoor unit's factory charge covers up to 24.6 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
What warranty does the Carrier Performance 25 5-Zone 36,000 BTU R-454B 208/230V (37MGRAQ36EA3) carry?
The manufacturer publishes these warranty tiers: Registered: 10 yr parts / no separate compressor term (eligible timely registered residential installation); Dealer alternative: 5 yr parts / no separate compressor term (Consumer Choice dealer alternative: 5-year parts plus 3-year labor through a participating dealer). Score uses Registered. Additional published terms are shown for reference and not counted in the score.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
