About Us

Althoff Industries Inc. was started in 1961 by Jim Althoff as a family-owned and operated HVAC business in the Crystal Lake, IL area. Over the years, as more people liked working with honest, well-trained, and experienced professionals, it became clear we needed to expand. Today, we run a company that deals in HVAC, electrical, plumbing, and more.

  • We offer quality services with a 100% satisfaction guarantee.
  • Our team provides solutions, not just quick fixes.
  • Our technicians are licensed and NATE-certified.

Althoff Industries Company Overview

Treating Customers Like Family

We didn’t get where we are today by pulling a fast one on our customers. We simply provide what homeowners want, even if it’s an out-of-the-box solution. We don’t need to lie or push products in order to provide people with the HVAC services they need. Good, hard-work by an experienced and certified team goes a long way in this business.

It’s time to hand it off to us. We care about the quality of your home’s air, the satisfaction of your family when they use drains and sinks, and the safety of your electrical system. Take a look at one of the many services we offer and tell us how we can help you today.
