60+ years of Sauk Valley comfort
Loescher Heating & Air Conditioning has been a family-owned fixture in Sterling since 1962. We are proud to be the team your neighbors recommend.
Rooted in Sterling, IL
We started with a simple promise: treat every home and business like our own. Three generations later, that promise still drives everything we do, from a midnight no-heat call to a planned system upgrade.
Our technicians are factory-trained, background-checked and licensed in Illinois. They take the time to do the job right and leave your space cleaner than they found it.
