For residents in Illinois, choosing John J. Cahill Plumbing, Heating & Air Conditioning is an investment in stability, expertise, and integrated service. The key factor worth choosing is the unparalleled combination of historical trust and modern, diversified service offerings.
In a region like Chicagoland, which experiences extreme seasonal weather, having a Heating contractor and Plumber from the same highly-rated company is a significant advantage.

Their team is intimately familiar with the demands placed on both Boiler Systems and plumbing from constant temperature fluctuations.
Furthermore, the presence of an in-house Bathroom remodeler and Kitchen Remodeling Contractors is a unique selling point. It means the critical and often complicated plumbing work during a renovation is seamlessly integrated with the design and construction, preventing the common coordination issues between trades. Customers seeking a full-service remodel can rely on their expertise from the initial design phase to the final installation of Bath Vanities and Kitchen Bathroom Fixture.
While one customer review noted that pricing could be "pricey," they immediately followed up by stating, "you pay for what you get! I got a very skilled and nice professional," confirming the value aligns with the quality of the service delivered. For many Illinois residents, particularly those with older homes who require specialized knowledge for challenging projects, choosing a company that is “reliable, trustworthy and gets the job done” every year—as one 30-year customer attested—is worth the investment. This reliability, combined with the convenience of a 24/7 Hour Emergency Service and the professional support of a local company with more than a century of experience, solidifies John J. Cahill as a top-tier choice for comprehensive home services in the Illinois region.

★ 5★ 4★ 3★ 2★ 1Charley came to my home and quickly repaired my a/c unit. He was very knowledgeable, pleasant, and put up with my dog. The cost was pricey for someone in my condo building, but you pay for what you get! I got a very skilled and nice professional. 😊I’d give five stars, except for the price.
July 14 · Chitown SI have been a Cahill customer since 1989 when we bought our home. Charlie just serviced my AC unit which Cahill installed in 2022 after the old one broke. Dave has yearly worked on cleaning roots from our sewer pipes as well as interior projects. Also, we have our furnace maintenance done each year. Cahill is very reliable, trustworthy and gets the job done. Use them, they are the best!
June 27 · Lucy FarrCharlie from John J. Cahill serviced both our air-conditioning and furnace today. (5/13/25)He was on time, professional, knowledgeable, friendly, & courteous.He explained both written and verbally what he did on each unit.I know some people feel Cahill in Evanston is higher priced than other companies. However, having someone in your home you can trust, honest, and stands by their work is well worth it.Thanks so much Cahill & Charlie,Julie Worden
May 13 · Julie WordenJohn J. Cahill Plumbing, Heating, and Air Conditioning is fantastic. It has serviced our house for 12 years and we have always found their employees to be reliable and responsive for both routine services and complicated projects. Most recently Tad from Cahill installed a new high efficiency Triangle Tube boiler for our radiator heat system. The boiler is connected to a "passive" hot water tank, which eliminates the need for a separate electric or gas hot water tank. Brilliant! Cahill also recently installed a hydronic (hot water) tubing-based radiant heating system to heat the floor in our remodeled kitchen (we didn't have the room for a radiator in the remodeled kitchen). This system also draws water from the Triangle Tube boiler. Also brilliant. The workmanship was excellent, and both run flawlessly. We also use the company for routine sewer maintenance. In short, we could not be happier with John J. Cahill's, Inc.'s service.
February 18 · John MooreI'm updating my previous review. I had gotten a bill from Cahill that I didn't agree with and left a review here. I got a very thoughtful call from Charlie Cahill to clear up the confusion. He was kind and thoughtful and I appreciated his professionalism. We settled for the full amount immediately thanks solely to his approach. Thanks, Charlie!
