"Schulz Heating and Cooling helped us solve a heating issue. The service was excellent. The new Lennox furnace is warmer, quieter and heats more efficiently than what we had. The work was completed in one day and the workmen were friendly and helpful. We also had AC installed for the first time. I would recommend their services to anyone looking at upgrading their heating and cooling needs." Mary L. Keshena, WI

"He fixed the problem right away, courteous and seemed very knowledgeable." Rated us 10 out of 10 - J. Bretl
