MRCOOL® Signature 2.5 Ton up to 14.3 SEER2 30,000 BTU Split Air Conditioner, MCAESAS4T3021AA

Product Description 

 

MRCOOL® Signature Series 30K 2.5-Ton Cooling-Only AC Condenser (230V)

The MRCOOL® Signature Series 30K (2.5-Ton) Air Conditioner Condenser is built for homeowners who need strong, reliable cooling during peak summer heat without unnecessary complexity or rising energy costs. It’s an excellent solution for replacing an older AC system or installing a new cooling-only setup in warm-weather climates.

With an efficiency rating of 14.3 SEER2 and 11.7 EER2, this condenser delivers consistent, cost-effective cooling while helping keep utility bills under control. The unit ships factory pre-charged with R-454B refrigerant, a next-generation, low-GWP refrigerant that meets modern environmental standards while maintaining dependable performance. The factory charge also helps reduce installation time and labor costs.

At the heart of the system is a durable single-speed scroll compressor, a proven design trusted for long service life, steady operation, and quiet performance. Inner-groove copper tubing improves heat transfer efficiency, allowing the system to cool more evenly and respond quickly to changing indoor temperatures.

Despite its higher capacity, the unit operates at just 63 dBA, making it well-suited for residential neighborhoods. A sound-dampening top, along with a steel louvered coil guard and wire fan discharge grille, helps protect internal components, reduce noise, and extend the life of the condenser.

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

If you’re looking for powerful cooling, quiet operation, and proven reliability, the MRCOOL Signature Series 30K AC condenser is a smart, dependable choice.
