Operating on R454B refrigerant at 208-230 volts, 1-phase power, this unit carries a 19 SEER efficiency rating and is marketed under the RunTru product line. It handles both cooling and heating functions as part of a matched outdoor unit system. Licensed HVAC technicians install this unit as part of a ductless split system in applications where running ductwork is impractical or cost-prohibitive. The indoor section mounts to a wall plate and connects to the outdoor condensing unit via refrigerant lineset and low-voltage control wiring.\u003c\/p\u003e\u003cp\u003eThis indoor air handler is suited for residential and light commercial single-zone applications. Typical installations include room additions, converted garages, server rooms, or any conditioned space where a standalone ductless solution is required. The unit operates with R454B refrigerant, a lower-GWP alternative to R410A, aligning with current industry refrigerant transition requirements. It is intended to be paired with a compatible Trane or RunTru outdoor condensing unit to form a complete mini-split heat pump system. HVAC technicians familiar with inverter-driven mini-split systems will recognize the standard wall-mount configuration with front-panel access for the air filter and internal components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24,000 BTU\/h cooling capacity suitable for spaces up to approximately 1,000-1,200 square feet depending on load conditions\u003c\/li\u003e\n\u003cli\u003e19 SEER efficiency rating for reduced operating costs relative to standard single-speed systems\u003c\/li\u003e\n\u003cli\u003eR454B refrigerant compliance meets current low-GWP refrigerant transition standards\u003c\/li\u003e\n\u003cli\u003e208-230 volt, 1-phase electrical connection compatible with standard residential and light commercial service\u003c\/li\u003e\n\u003cli\u003eWall-mount design with mounting plate, front-access air filter, and integrated drainage pipe for straightforward installation\u003c\/li\u003e\n\u003cli\u003eHeat pump IDU supports both heating and cooling modes from a single indoor unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe M5MHWUN24A1N0A is a RunTru-branded Trane ductless indoor air handler designed to be paired with a compatible Trane or RunTru 24,000 BTU outdoor condensing unit in a matched single-zone mini-split heat pump system using R454B refrigerant.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 refrigerant handling certification for R454B systems. Before any service or connection work, confirm that all power to the circuit is de-energized at the breaker. Refrigerant lineset sizing, line set length, and system evacuation procedures must follow the manufacturer installer guide (document 88-M5MHWUN-1A-EN) and applicable local mechanical codes. Do not operate the unit in cooling mode below the manufacturer-specified ambient temperature range, and ensure the condensate drain line is pitched correctly to prevent standing water in the drain pan.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Capacity\u003c\/strong\u003e: 24,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSEER Rating\u003c\/strong\u003e: 19 SEER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: R454B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208-230 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1-phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Type\u003c\/strong\u003e: Wall-mounted ductless indoor air handler (heat pump)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line\u003c\/strong\u003e: RunTru\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Trane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M5MHWUN24A1N0A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51077825462578,"sku":"M5MHWUN24A1N0A","price":609.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308797324.webp?v=1780589007","url":"https:\/\/voomisupply.com\/products\/trane-m5mhwun24a1n0a-ductless-runtru-24k-19-seer-idu-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
