The M5THS19 is a RunTru RunTru single-zone heat pump mini-split system paired with a wall-mounted indoor unit. Available in capacities from 9,000 to 36,000 BTU, it uses R-454B refrigerant and reaches up to 19.0 SEER2. Core Comfort HVAC installs the M5THS19 throughout the Phoenix metro area for garages, casitas, bedrooms, home additions, and light commercial spaces.
As a single-zone system, the M5THS19 pairs one outdoor condenser with one wall-mounted indoor unit to condition a single room or space. We review your room size, insulation, sun exposure, and ceiling height to confirm the right capacity, then plan placement, line routing, drainage, and the electrical connection.

EQUIPMENT & INSTALLATION
Core Comfort HVAC installs the M5THS19 single-zone heat pump across Phoenix, Scottsdale, Mesa, Tempe, Gilbert, Chandler, and the surrounding valley. Whether you're cooling a garage workshop, a bedroom addition, a casita, or an open commercial area, we size the system to your space and explain the equipment, placement, and schedule before work starts.
A 9,000 BTU unit suits a small room or one-car garage, while the 36,000 BTU configuration handles larger garages, workshops, and open living areas. We review your room's square footage, insulation, window exposure, and ceiling height, then recommend the capacity that keeps the space comfortable without short-cycling. The wall-mounted indoor unit sits high on an exterior-facing wall for clean line routing and even airflow.
Your installation covers mounting the indoor and outdoor units, connecting the refrigerant lines, installing line-set covers, arranging condensate drainage, and completing the required electrical connection. We include a concrete-grade equipment pad and basic electrical when the unit is garage-adjacent. Additional electrical work, long line runs, or difficult access can affect the scope — we explain what's included in your written quote before scheduling.
Every M5THS19 installation by Core Comfort HVAC is backed by a 10-year labor warranty on installation workmanship, plus the manufacturer's parts warranty on the equipment. We walk you through the controls, filter care, and what to watch for after install. Keep your written quote and equipment documents with your model and serial numbers for warranty registration.
