MRCOOL® Signature 2 Ton up to 14.3 SEER2 24,000 BTU Split Air Conditioner, MCAESAS4T2421AA

Product Description 

 

MRCOOL® Signature Series 24K 2-Ton Cooling-Only AC Condenser (230V)

The MRCOOL® Signature Series 24K (2-Ton) Air Conditioner Condenser is built for homeowners who want reliable, efficient cooling without unnecessary complexity or rising energy bills. Whether you’re replacing an aging AC system or installing new equipment, this cooling-only condenser delivers dependable comfort for warm-weather climates.

Rated at 14.3 SEER2 and 11.7 EER2, this unit provides consistent cooling performance while helping control monthly energy costs. It arrives factory pre-charged with R-454B refrigerant, a next-generation, low-GWP refrigerant developed to meet today’s environmental standards. This factory charge also helps reduce installation time and labor costs.

At the core of the system is a single-speed scroll compressor, a proven design known for quiet operation, long service life, and steady performance. Inner-groove copper tubing improves heat transfer efficiency, allowing the system to respond quickly to cooling demands and maintain even indoor temperatures.

Despite its solid output, the unit operates at just 60 dBA, making it quiet enough for residential neighborhoods. A sound-dampening top, along with a steel louvered coil guard and wire fan discharge grille, helps protect internal components while reducing noise and extending system life.

Designed to pair with MRCOOL® Signature Series multi-position or stud-mount air handlers, this condenser is backed by a 10-year parts warranty and a limited lifetime compressor warranty, giving homeowners confidence in their long-term investment.

If you’re looking for a simple, efficient, and dependable cooling solution, the MRCOOL Signature Series 24K AC condenser is a smart choice.
