Description

About this model

The Carrier 24SCA5***C is the coastal version of the Comfort 15 (24SCA5), a single-stage Comfort series air conditioner using Puron (R-410A) refrigerant. Carrier’s product data for the coastal version carries the same ratings as the standard Comfort 15. It runs at one speed, cycling on and off as the thermostat calls for cooling, and works with a standard thermostat.

The specifications below are Carrier’s published figures for the 24SCA5***C itself, not for any newer model. Carrier published both legacy SEER/EER and SEER2/EER2 ratings for this model; both are shown and labeled.

Replacement options

Current Carrier alternative: Carrier Comfort 16 Air Conditioner (26SCA5)

Carrier has not named a direct successor to the 24SCA5***C. The closest current model is the Carrier Comfort 16 Air Conditioner (26SCA5): Carrier’s current single-stage Comfort series model (previously listed on this site as the Comfort 15). The coastal version’s extra corrosion protection is intended for salt-air locations and offers no additional benefit inland in our service area; Carrier also offers a coastal version of the 26SCA5 (26SCA5***C) if one is ever required. 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 26SCA5 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 24SCA5***C to the 26SCA5 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 24SCA5***C still made?

No. Carrier lists the 24SCA5***C as no longer in production. Carrier has not named a direct successor; the closest current Carrier alternative is the Comfort 16 (26SCA5).

Can I still get my 24SCA5***C repaired?

Yes. GSHA Services, LTD repairs and maintains R-410A Carrier air conditioners, including the 24SCA5***C, 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 24SCA5***C 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 24SCA5***C?

The closest current Carrier alternative is the Carrier Comfort 16 Air Conditioner (26SCA5), Carrier’s current single-stage Comfort series model (previously listed on this site as the Comfort 15), 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.
