Overview

Product Overview

The MRCOOL® Signature Series 30k Heat Pump Condenser delivers reliable, energy-efficient performance year-round. With ratings of 14.3 SEER2 and 11.7 EER2, it offers consistent heating and cooling while helping homeowners manage energy costs in every season. Whether battling intense summer heat or chilly winter air, this system is built to maintain a comfortable indoor environment.

The unit comes pre-charged with R-454B refrigerant, a low-GWP alternative that aligns with current environmental standards. This refrigerant reduces environmental impact without compromising performance. The pre-charged design speeds up installation, reducing both time and labor expenses.

At the heart of the system is a rugged single-speed scroll compressor that ensures steady, efficient operation. Inner-groove copper tubing enhances heat transfer, while integrated pressure and temperature sensors protect against extreme conditions. An intelligent defrost function maintains reliable performance in cold weather by preventing frost buildup.

Despite its powerful capabilities, the Signature Series 30k runs quietly at just 63 decibels. A sound-dampening top helps keep operational noise to a minimum, making it suitable for residential areas. For added durability, the exterior features a steel louver coil guard and wire fan discharge grille for extra protection.

With sweat connection service valves and an easy-access gauge port, installation and maintenance are simple. Backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, it’s a dependable investment in long-term home comfort.

Manufacturer Warranty

Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.

Professional Installation Recommended

Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us before you order.

Before You Order

Make sure it is the right size, and that you have the rest of it

Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.
