Description

About this model

The Carrier 24VNA6 is a variable-speed Infinity air conditioner with Greenspeed Intelligence that uses Puron (R-410A) refrigerant. Its inverter-driven compressor adjusts output between 25 and 100 percent of capacity, so it runs long, low-speed cycles that hold steadier temperatures, remove more humidity and keep outdoor sound as low as 51 dBA. It requires the Infinity Control with Greenspeed capability.

Replacement options

Current Carrier alternative: Carrier Infinity 21 Air Conditioner (26VNA1)

Carrier has not named a direct successor to the 24VNA6. The closest current model is the Carrier Infinity 21 Air Conditioner (26VNA1): Carrier’s current variable-speed Infinity model with Greenspeed Intelligence; it requires the Infinity System Control. It is the variable-speed Infinity air conditioner in Carrier’s current lineup, with Greenspeed Intelligence and the same 2- to 5-ton range. It is offered in 2, 3, 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 26VNA1 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 24VNA6 to the 26VNA1 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 24VNA6 still made?

No. Carrier lists the 24VNA6 as no longer in production. Carrier has not named a direct successor; the closest current Carrier alternative is the Infinity 21 (26VNA1).

Can I still get my 24VNA6 repaired?

Yes. GSHA Services, LTD repairs and maintains R-410A Carrier air conditioners, including the 24VNA6, 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 24VNA6 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 24VNA6?

The closest current Carrier alternative is the Carrier Infinity 21 Air Conditioner (26VNA1), Carrier’s current variable-speed Infinity model with Greenspeed Intelligence; it requires the Infinity System Control, 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.
