DIY 4th Generation 9K - 36K BTU Heat Pump Wall Mount Air Handler 115-230 volt and Enhanced WiFi (Works with Alexa, Works with Go – 115v / 12K BTU

MrCool DIY 4th Gen Air Handler for Quiet Room Climate In a sealed grow room or greenhouse, a swing between hot and humid stresses the canopy and invites mold. A loud window unit only trades one problem for another. This wall-mounted indoor air handler answers with a 12,000 BTU inverter heat pump. It cools and heats a space up to about 500 square feet. The inverter ramps output to hold a set temperature instead of cycling hard. The canopy stays even and the humidity holds where plants want it, at a quiet 23.5 dBA. It runs on standard 115V house power, so no special circuit is needed for a single-zone install. That drops precise, quiet climate control into a grow tent, greenhouse corner, or indoor garden. WiFi Indoor Unit, Pairs with a DIY Condenser Built-in WiFi and the SmartHVAC app let a grower set temperature and schedules from a phone. It also works with Alexa and Google Assistant for voice control. A grower can hold a night-and-day temperature curve while away from the room. Auto-restart brings it back after a power blip, and a sleep mode trims output overnight. This is the indoor air handler only. It pairs with a matching DIY 4th Gen condenser and a pre-charged line set for a complete single-zone system. The quick-connect design keeps the install to drill, mount, and connect, with no special tools or vacuum pump. At 24 pounds and Energy Star efficient, it mounts high on a wall and out of the canopy.
