Signature TruInverter
Homeowners and professionals can purchase this equipment online. This is an individual outdoor condenser, not a complete indoor/outdoor system. Matching equipment and installation materials are separate unless expressly listed as included.
The MRCOOL TruInverter outdoor-unit manual requires installation by professionals or qualified personnel. Use the exact-model installation instructions and a verified equipment match. Refrigerant connections, evacuation, commissioning, electrical work, ductwork and permits require appropriate expertise. A licensed contractor is required where applicable law or manufacturer-directed diagnostics require one.
The applicable limited warranty provides 10-year limited parts coverage and limited lifetime compressor coverage for the original owner, as defined in the document. Labor, installation, diagnostics, refrigerant and freight are excluded under the linked terms. Coverage is subject to authorized-dealer purchase, compliant installation, approved matching, maintenance and the other conditions and exclusions in the warranty.
Keep proof of purchase and installation records. Follow any registration instructions supplied with your equipment; the linked warranty does not state a registration-based extension deadline. Optional CPS protection is separate from the manufacturer warranty.
Read the Signature TruInverter warranty PDF ↗The MRCOOL Signature Series TruInverter 48K heat pump condenser provides efficient, variable-speed heating and cooling for whole-home comfort. TruInverter technology continuously adjusts compressor output to reduce temperature swings, improve humidity control, lower sound levels, and avoid the energy waste of frequent on-off cycling.
The MRCOOL Signature Series TruInverter 48K heat pump condenser provides efficient, variable-speed heating and cooling for whole-home comfort. TruInverter technology continuously adjusts compressor output to reduce temperature swings, improve humidity control, lower sound levels, and avoid the energy waste of frequent on-off cycling.
The outdoor unit is factory-charged with lower-GWP R-454B refrigerant. Follow the exact-model manufacturer requirements for refrigerant piping, leak testing and commissioning. A durable gunmetal cabinet and protected outdoor coil help it stand up to demanding year-round operation.
This listing includes the outdoor condenser only. Pair it with the compatible TruInverter multi-position air handler MCAEAMPVT48F21BA. A thermostat, line set, heat kit, and other installation materials are sold separately. Licensed professional installation is required.

Coverage starts from proof of purchase and is non-transferable. Authorized-dealer purchase, approved equipment matching, compliant installation and maintenance are required.

PLAN YOUR WHOLE-HOME COMFORT
A matched air handler and outdoor heat pump connect with refrigerant piping. Plan indoor space, duct airflow and the exact connection method.
Buying difference: verify the actual equipment package and line-set configuration. HyperHeat, VersaPro, Universal and Signature have distinct purchasing rules; Signature stays professional/traditional.
Explore central ducted systems ↗Heating and cooling equipment is assembled outdoors and connected to your ducts. Verify discharge direction, design-temperature heating output and electrical service.
Buying difference: no split-system line set. Optional auxiliary heat needs an exact compatible kit and circuit plan; it is not assumed included.
Explore packaged equipment ↗One outdoor cabinet combines a gas furnace and air conditioning. Your qualified installer must verify fuel supply, combustion, exhaust and duct configuration.
Buying difference: gas input is not delivered heat output. Do not assume conversion-kit availability or homeowner installation.
Explore gas/electric equipment ↗REPLACEMENT SEASON, PLANNED WELL
For cold-weather replacement, compare exact heating output at your local design conditions—not nominal tonnage alone. Existing ducts, available fuel, electrical capacity and professional installation all matter. Have a qualified installer verify the exact model’s heating performance, available service and site requirements.
