Best Mitsubishi Mini Split in Milwaukee WI

Omer from O & W Heating and Cooling was more than accommodating, he came in first for an issue with our thermostat and we had him install a new furnace and air conditioner. He took the time to explain and show us all the issues with our very old furnace . He was prompt/courteous and install was perfect. We love our new furnace! Would only recommend O & W.
