Description
This MRCOOL DIY 5th Generation 4-Zone Mini Split pairs a 36,000 BTU ductless heat pump condenser with four wall-mount indoor air handlers rated at 18K + 9K + 9K + 9K BTU, giving each zone independent temperature control. The condenser is rated at SEER2 23 and HSPF2 9.9, and the system's DIY QuickConnect line sets come pre-charged with R-454B refrigerant, so installation doesn't require vacuuming or a licensed HVAC technician.
Highlights
- Pre-charged 25-ft DIY QuickConnect line sets (R-454B refrigerant) eliminate the vacuuming step, cutting installation time and cost.
- Included DIYPRO cable removes the need for electrical conduit while adding durability against outdoor elements.
- Control every zone from the included wireless remote, the SmartHVAC app (iOS/Android), or hands-free through Amazon Alexa and Google Assistant.
- Follow Me function tracks the temperature near the remote's location so each zone stays evenly comfortable.
- Rated SEER2 23 / HSPF2 9.9 for efficient year-round heating and cooling.
- Gold Fin condenser coil offers extra corrosion resistance, a benefit in coastal environments.
- Dry Mode helps the system pull excess humidity out of the air.
Details
Avermont Direct is an authorized MRCOOL dealer, and this 4-Zone DIY Mini Split System is well suited to homeowners who want to condition several rooms — such as a primary suite, home office, and living areas — from a single outdoor condenser using wall-mount air handlers. The system is backed by a 5-year parts warranty and a 7-year compressor warranty from MRCOOL, with a Limited Lifetime Replacement warranty available to owners who enroll in the MRCOOL Care Program. Because the line sets arrive pre-charged with R-454B refrigerant, most homeowners can complete the installation themselves without hiring an HVAC contractor.
