Plumbing, and Electrical Since 1965.


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.

“Prices were extraordinarily high. 2 parts that probably TOTALED a cost of less than $150 and my elderly mom was charged $304.70 FOR EACH! Call and ask about it and get told "It's the price of doing business." What a crappy operation that is being run here! First tech couldn't even get it fixed after 4 hours, and had to go back and get help to finally get it working. I told the manager that I was surprised they even had a business, and in a smug tone was told "have been for 35 years."

Steer clear of this business if you value money and quality people to help with your A/C repairs!

Can't give ZERO stars for the review, but would if I could!”

“I've been a member and customer for more than 20 years and have never once been anything but impressed with all aspects of the relationship and services. AC, furnace water heater replacements over the years. I know it's because of Chris Carpenter's leadership and commitment to the customer. Good man. I had routine HVAC maintenance done yesterday by Ethan who has been my tech a few times now and can't say enough about him, his professionalism, knowledge, personality, respect for the customer, etc, etc. Great "kid" as has been the case for all prior techs. It's been a consistent theme. These days, you just don't see this level of consistent service and caring much. I can only give five stars here but I give them a ten.”
