ABOUT US

When you choose to live in the community you grew up in, you simply care more. We’re the Carpenters, and we’ve been proudly serving homes and businesses in the Northern Illinois area for more than 50 years.

Founded in 1965 by our grandfather, Walter Carpenter, we adhere to the same principles that established him as a local leader in HVAC, plumbing, sewer, and electrical services.

We do work on a daily basis across Northern Illinois, including Kane County, DeKalb County, DuPage County, and Ogle County. We’ve been able to put together a tremendous and fairly large team of the area’s best tradesmen deployed throughout this area.

When you call us, you can always be certain we have a certified, experienced HVAC technician or plumber near you who is ready to help. Learn about our HVAC Guarantees.
