Signature 1.5 Ton up to 14.3 SEER2 18,000 BTU Split System Heat Pump

The MRCOOL® Signature Series 18k Heat Pump Condenser offers efficient, reliable comfort all year long. Rated at 14.3 SEER2 and 11.7 EER2, it delivers dependable heating and cooling while helping lower monthly energy bills. Whether upgrading an old system or installing new, this unit balances performance, efficiency, and value.

Pre-charged with eco-friendly R-454B refrigerant, this unit supports reduced environmental impact while maintaining strong performance. The pre-charged design streamlines installation and cuts labor time, making it ideal for both contractors and homeowners.

At the heart of the system is a single-speed scroll compressor, engineered for stable, efficient operation. Inner-groove copper tubing enhances heat transfer, boosting responsiveness and energy efficiency. Built-in sensors monitor internal temperature and pressure, helping protect against extreme conditions. An intelligent defrost function keeps the unit running smoothly in cold weather.

Despite its power, the unit runs quietly at just 60 decibels, about as loud as the average dishwasher, with a specially-engineered sound-dampening top to reduce noise.

Compact and lightweight, the unit installs easily in tight spaces. And maintenance is simple with accessible service valves and gauge ports. A 10-year limited parts warranty and a limited lifetime compressor warranty offers added peace of mind. The MRCOOL® Signature Series 18k Heat Pump Condenser is a durable, efficient, and smart investment in home comfort.
