MRCOOL DIY Select Mini Split Systems - 1 Room

The MRCOOL DIY Select is MRCOOL's most affordable single-zone mini split. It's designed for homeowners who need to condition one room — a home office, garage, sunroom, or spare bedroom — in a moderate climate where winter lows stay well above freezing.

What you get:

• 💰 Lowest upfront cost: The most budget-friendly entry into MRCOOL's DIY lineup.
• 🔧 True DIY installation: Pre-charged Quick Connect® line set and DIYPRO® cable mean no HVAC professional is required.
• ⚡ 16.5–17.5 SEER2 efficiency: Solid for a single room, but not as efficient as other MRCOOL lines.
• 📦 Single-zone only: One indoor unit, one outdoor condenser, one room.
• 🛡️ 2-year compressor / 1-year parts warranty: Standard coverage — no registration required for these terms.

The honest take: Select is the right choice if upfront price is your primary constraint and you're willing to accept lower efficiency and shorter warranty coverage to get there. It'll heat and cool a single room — just know you're trading long-term value for a lower sticker price. See how it compares to Easy Pro and 5th Gen →
