Description

The MRCOOL 18k DIY 5th Generation Mini‑Split Air Handler 230V is built for larger rooms up to 750 sq. ft., making it an excellent choice for living rooms, large master suites, open‑concept spaces, workshops, and bonus rooms. As part of the 5th Generation DIY lineup, this air handler delivers powerful heating and cooling performance while allowing homeowners to install the system without professional HVAC tools or training.

When paired with MRCOOL’s DIY QuickConnect® pre‑charged line sets (sold separately), installation becomes fast, clean, and accessible — no vacuum pump, gauges, or refrigerant handling required. The included DIYPRO cable provides enhanced durability and eliminates the need for electrical conduit, simplifying installation even further.

Comfort control is flexible and intuitive. Use the SmartHVAC app, the included wireless remote, or hands‑free voice commands through Amazon Alexa and Google Assistant. With Follow Me® technology, the system adjusts temperature based on the remote’s location, ensuring more accurate comfort throughout the room.

Built for long‑term reliability, the air handler features a Gold Fin anti‑corrosion coating, making it ideal for coastal environments like Corpus Christi. Backed by MRCOOL’s industry‑leading warranty — including a limited lifetime compressor warranty when paired with a DIY condenser — this 18k air handler is a durable, efficient, and smart solution for year‑round comfort.
