The HVAC Mirage WINTEK 12000 BTU Air Handler (110V) is a high-performance indoor component designed for quiet, efficient cooling and heating. Ideal for replacing an existing unit or building a custom system, this air handler delivers reliable variable-speed comfort.
As a standalone 12000 BTU indoor wall-mounted air handler, this component requires a matching outdoor condenser to function. Built for the R-454B Low-GWP mandate, it incorporates variable speed comfort technology when paired with a compatible inverter-driven system. Proper installation by a licensed professional ensures maximum efficiency and longevity.
Indoor Air Handler
Wireless Remote Control
- Requires dedicated 110V (115V / 60Hz 1Ph) electrical circuit.
- Requires 3/8" Liquid x 7/8" Suction copper line set.
- NOT INCLUDED: Outdoor condenser, line set, or wall mounting bracket.
Pro-Installer Tip: When installing this non-DIY air handler, leaking flare connections are the most common cause of early failure. To prevent refrigerant loss and ensure system longevity, always use an Eccentric Flaring Tool and a Digital Torque Wrench to tighten fittings to factory spec. Under EPA 608 mandates, a professional must pull a deep vacuum below 500 microns before releasing the R-454B refrigerant. Use 14/4 AWG stranded wire between indoor and outdoor sections to prevent communication codes.
- Variable Speed Comfort: Delivers consistent temperature control when paired with an inverter condenser.
- 18 SEER2 Efficiency: Optimizes energy usage to lower utility bills.
- Eco-Friendly: Compliant with the 2026 R-454B Low-GWP refrigerant mandate.
- Quiet Operation: Designed to minimize indoor noise levels.
