          Frequently Asked Questions about MRCOOL Universal 4-5 Ton 18 SEER Central Heat Pump Split System with 25 ft. Lineset, MDU18048060-25

          Most Frequently Asked Questions

          The life expectancy of a MRCOOL mini-split system is typically 12 to 20 years with proper installation, regular maintenance, and normal usage.

          Yes, most MRCOOL mini splits are manufactured in China, as MRCOOL partners with established Chinese HVAC manufacturers to produce their systems.

          The MRCOOL 18,000 BTU mini split typically requires a 208/230V, 60Hz, single-phase power supply with a 15-20 amp dedicated circuit and appropriately sized wiring (usually 12- or 14-gauge), but you should always consult the specific model’s manual and local electrical codes for exact requirements.

          Other Questions

          MRCOOL HVAC systems are designed, branded, and distributed by MRCOOL LLC, an American company based in Kentucky, but the manufacturing is primarily carried out by established HVAC factories in China, such as Midea and Gree, under contract for MRCOOL.

          The cost to run an 18,000 BTU mini split depends on its efficiency and your local electricity rate, but typically, if the unit has a SEER rating of 20 and electricity costs $0.15 per kWh, running it at full capacity for 8 hours would cost about $1.08 per day (calculated as 1.8 kW × 8 hours × $0.15/kWh = $2.16; however, mini splits rarely run at full capacity continuously, so the average cost is usually less, around $1 to $2 per day).
