MR COOL Installation Experts
Mr Cool DIY is the only mini-split designed for non-HVAC installers — the pre-charged DIY line sets snap together without a vacuum pump or refrigerant license. That said, getting it RIGHT (line set routing, condensate drain, electrical connection, mounting heights) still takes experience. We install dozens of Mr Cool systems and know every gotcha — from line-set angles to wall-pass-through sealing.
