Frequently Asked Questions About Mini Split Service in Cornell, WI

In winter, a light coating of frost is normal before the system enters its defrost cycle. However, if the outdoor unit is completely encased in thick ice, the defrost control board, reversing valve, or fan motor has likely failed. Call (877) 359-0825 for immediate service.
For maximum energy efficiency, set the thermostat between 72-78°F in summer and 68-72°F in winter. Unlike traditional systems, mini splits use inverter technology and work best when you set a comfortable temperature and leave it alone rather than constantly adjusting it.
Your ductless system should be professionally serviced at least once a year. If you use it year-round for both heating and cooling in Cornell, WI, schedule maintenance twice a year (spring and fall) to ensure maximum efficiency and prevent unexpected breakdowns.
