Description

About this model

The Carrier 24ABB3 was sold as the Comfort 13 single-stage air conditioner with Puron (R-410A) refrigerant. It runs at one speed, works with a standard thermostat, and was offered in 1.5- to 5-ton sizes.

The specifications below are Carrier’s published figures for the 24ABB3 itself, not for any newer model. Carrier rated this model under the older SEER/EER method and never published SEER2/EER2 figures for it, so the efficiency figures are legacy ratings.

Replacement options

Current Carrier alternative: Carrier Comfort 14 Air Conditioner (26SCA4)

Carrier has not named a direct successor to the 24ABB3. The closest current model is the Carrier Comfort 14 Air Conditioner (26SCA4): Carrier’s current single-stage Comfort series model at the entry point of the current line. It is Carrier’s current entry-tier single-stage model in the same 1.5- to 5-ton range; 13 SEER equipment like the 24ABB3 is below the efficiency required for new installations today. It is offered in 1.5, 2, 2.5, 3, 3.5, 4 and 5 tons and is installed by GSHA Services, LTD as a complete installed package with a free in-home estimate; installed pricing by size is on its product page.

The 26SCA4 uses Carrier’s current R-454B refrigerant (Puron Advance), the lower-global-warming-potential refrigerant in Carrier’s current residential line. R-454B cannot be added to an existing R-410A system, and an existing R-410A system does not need to be replaced because of its refrigerant. A change from the 24ABB3 to the 26SCA4 is a full system change rather than a swap of the outdoor unit alone, and a free in-home estimate confirms the correct size and the matching indoor coil. See our air conditioner installation page for how an installation works; financing is available with approved credit.

Frequently asked questions

Is the Carrier 24ABB3 still made?

The 24ABB3 is no longer in Carrier’s current residential air conditioner lineup. Carrier has not named a direct successor; the closest current Carrier alternative is the Comfort 14 (26SCA4).

Can I still get my 24ABB3 repaired?

Yes. GSHA Services, LTD repairs and maintains R-410A Carrier air conditioners, including the 24ABB3, and R-410A refrigerant remains available for servicing existing systems. Schedule AC repair online or call (224) 220-3660.

Do I have to replace my 24ABB3 because it is discontinued?

No. A discontinued model can keep running as long as it is repairable and maintained. Replacement becomes worth discussing when repair costs climb, the compressor fails, or the system can no longer keep the house comfortable; a technician can give you an honest picture at a repair visit.

What replaces the Carrier 24ABB3?

The closest current Carrier alternative is the Carrier Comfort 14 Air Conditioner (26SCA4), Carrier’s current single-stage Comfort series model at the entry point of the current line, with R-454B refrigerant. It is not a Carrier-designated direct replacement, so a free estimate determines whether it is the right fit for your home.

Can a new R-454B unit connect to my existing indoor coil?

Usually not. In most replacements the indoor coil is replaced along with the outdoor unit so the two are a matched R-454B system; line-set and control compatibility are checked at the same time. Our free in-home estimate determines exactly what your system needs.
