Our second-generation family business, based in Troy, IL, has been serving the Metro East and greater St. Louis region for more than 30 years.

RESIDENTIAL & COMMERCIAL SERVICES

Our Services

We do everything from minor plumbing repairs to electrical installations to full-scale kitchen and bathroom upgrades. We sell, install, maintain, and fix air conditioners, furnaces, water heaters, water softeners, ducts, boilers, walk-in cooling units, garbage disposals, and many more appliances.

Because we’re concerned with cost savings and with healthy environments, we approach projects with energy efficiency in mind. We look at indoor air and water quality to address avoidable pollution problems.

We strive for same-day repair service for both our commercial and residential customers.

“I just wanted to give a shout out to the amazing on-call tech last night that came out and fixed our plumbing issue. He was professional, courteous, and answered all the questions we had. He made an extremely stressful situation so much more bearable.”
