About Us

Althoff Home Services 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.

Hand It Off to Althoff.

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.

Backed by more than 60 years of doing things right. Hand it off to Althoff!

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.

Did we mention that we provide all of our quotes before we perform any work? You get honest prices from pros that know what they’re doing when you call us. We even provide true 24-hour emergency services for homeowners in the Greater Chicago Area that need our help.

We are focused on exceeding expectations with every visit. Contact us today.

Core Values

We adhere to a strict set of core values that fuels our passion. Every service call, every installation, and every maintenance visit is a good time for us to exhibit these values.

  • Give Remarkable Service. Work should speak for itself. If we can wow our customers with our work, then that’s what really matters. We want to exceed expectations and honor our commitments.
  • Don’t Get Beat. We’ll own every outcome and strive to do better if anything doesn’t meet your expectations. We don’t back down from a challenge and we won’t give up on making things right for our customers.
  • Lead Ourselves. By embracing positivity and change, we want to be pioneers and leaders in this industry and in the local community. True leadership starts from within, and cultivate a team of leaders who know what they’re doing.
  • Excellence Together. A company is only as good as its people. We cultivate a community of sharp, experienced, and friendly employees who embody these core values on a daily basis.
  • Stronger Together: Community & Family. When we trust our team members as well as our customers, our jobs get a lot easier. We take part in community events and regularly treat each other like friends and family.

With Althoff, Good Enough Isn’t Good Enough. We work hard to wow our customers and get things done the right way, every time.
