“From our first call for help and quote, Gross showed their personal concern for our well-being—the first question [they asked] was ‘do you have heat now?’ From that point forward, Gross was quick, punctual, and efficient. Great service. Great work, and great guys to work with. Thank you, Gross Heating. You’ve earned us as a customer hands down.”
Brian T.

“Our family recently had our furnace replaced by Gross Heating & Air Conditioning. The attention to detail was meticulous with a high quality of work… We were very pleased with the entire process and would highly recommend Gross Heating & Air Conditioning.”

“In the beginning of February, Milwaukee was experiencing extremely cold temperatures and our 17-year-old furnace failed. We called Gross Heating and within an hour, they had a repair person at our house… Very professional all the way around. Thank you, Gross Heating!”

“They were terrific. They responded immediately and installed two new furnaces for my duplex… They did a beautiful, professional job.”
Barbara P.

“The Gross crew worked diligently to meet our heating and cooling needs and did so in a professional and timely manner. No easy feat when working on a nearly 100-year-old three-story duplex with hot water heat. We could not be more satisfied with excellent work done by Gross Heating & Air Conditioning.”
Charles L.

“Mike and Erik were friendly and informative with our AC, radon, and humidifier/dehumidifier installation. I would highly recommend their services.”
