MRCOOL 12K BTU Advantage 5th Generation Complete Ductless Mini-Split System

For a single-zone 12,000 BTU system, the best-built option we carry from MRCOOL is the MRCOOL 12K BTU DIY 5th Generation Complete Ductless Mini-Split System. It features the strongest warranty in the MRCOOL 12K single-zone lineup with 7 years on the compressor and 5 years on parts. This model is also the only 12K single-zone system we stock that holds an Energy Star listing in addition to the standard AHRI, ETL, and UL listings. It is the quietest option at 43 dBA indoors and ships complete with the air handler, condenser, and a pre-charged 25-foot DIYPro lineset. It operates on 115V, uses R-454B refrigerant, has an anti-corrosion fin coating, and can cover up to 550 square feet. If you desire similar build quality at a lower price point, the MRCOOL 12K BTU DIY EZ Pro Complete Ductless Mini-Split System - R454B is the next best option. It comes with a 5-year compressor and 3-year parts warranty, a pre-charged lineset, Gold Fin corrosion-resistant condenser coating, and CSA and ETL listings. The air handler, condenser, and installation kit are all included. The MRCOOL 12K BTU Advantage 5th Generation Complete Ductless Mini-Split System, which you are currently viewing, is the entry-level option in this range. While it is a capable unit featuring DC inverter technology, Goldfin corrosion resistance, and leakage detection, it has a shorter 2-year compressor and 1-year parts warranty. Additionally, MRCOOL requires installation by a licensed HVAC technician for the warranty to remain valid. The DIY and EZ Pro systems are designed for self-installation without special tools. All three systems ship the same business day. Our Mini Split Buyers Guide can help you confirm if 12K BTU is the correct capacity for your space.
