What is MRCOOL?

MRCOOL has carved out a unique and popular niche in the HVAC industry by pioneering the Do-It-Yourself (DIY) ductless mini-split system.

The core innovation is the use of pre-charged line sets and quick-connect fittings, which allows almost any homeowner to install a complete heating and cooling system without the specialized tools (like vacuum pumps or manifold gauges) or the professional expertise typically required for handling refrigerant. This design choice makes MRCOOL the go-to brand for reducing installation costs and bringing comfort to spaces like detached garages, sunrooms, and new home additions.

Beyond the revolutionary DIY line, MRCOOL also offers the Advantage Series for professional installation and the Olympus Series for flexible multi-zone configurations. All systems feature high SEER ratings (up to 22 SEER depending on the model), ensuring that the ease of installation does not come at the expense of energy efficiency. Furthermore, MRCOOL systems are designed as effective heat pumps, with many models capable of operating efficiently for heat generation in freezing conditions, providing year-round comfort.

DIY-Friendly Installation and Valid Warranty

The most significant benefit of the MRCOOL DIY series is its unique warranty structure. Unlike most competitor mini-splits, the MRCOOL DIY limited warranty remains valid even when the system is installed by the homeowner, provided the installation follows the manufacturer's instructions. This eliminates the friction point between DIY installation and standard HVAC warranty requirements. The company also offers a pathway to an Extended Limited Lifetime Compressor Warranty for DIY models through enrollment in their MRCOOL Care Kit Program, ensuring long-term protection for your investment.

FAQs/Frequently Asked Questions

Q: What makes the MRCOOL DIY Series installation process so easy?

A: The MRCOOL DIY series is easy because it uses pre-charged refrigerant line sets with specialized quick-connect fittings. This eliminates the need for expensive HVAC tools, such as a vacuum pump, and means the homeowner never has to handle or charge refrigerant, simplifying the entire setup.

Q: Does installing a MRCOOL DIY unit myself void the warranty?

A: No. The MRCOOL DIY Series is unique in that its warranty is explicitly valid for self-installation, provided you follow the included instructions and local electrical codes. A state-certified HVAC contractor is not required.

Q: What is the "MRCOOL Care Kit Program"?

A: The MRCOOL Care Kit Program is a subscription service that provides the registered owner with a DIY cleaning kit every six months. Enrollment in this program is a requirement to qualify for the Extended Limited Lifetime Compressor Replacement Warranty on DIY models.

Q: Are MRCOOL systems energy efficient and capable of cold-climate heating?

A: Yes. MRCOOL systems boast high SEER ratings, with some models reaching up to 22 SEER, which ensures substantial energy savings. Many units are designed to function as effective heat pumps, providing reliable heating performance even in low ambient temperatures, some as low as -13°F.

Q: Does the MRCOOL DIY system require special electrical wiring?

A: Some smaller, single-zone MRCOOL DIY units (typically 9k and 12k BTU) operate on a standard 115V power supply, which can make installation simpler. Larger units and all multi-zone condensers require a 230V connection and a dedicated breaker, similar to traditional HVAC systems.
