Toptec Htg, Clg, Plmg & Electrical, Inc

Since 1993, we have helped homeowners and commercial property owners throughout Northeastern Illinois maintain comfortable, dependable buildings. Based in Libertyville, we are family-owned and provide heating, cooling, plumbing, electrical, sewer and drain, duct-cleaning, indoor air quality, and geothermal services. Our TOPTEC-Certified technicians service all makes and models, and our team is available for emergencies 24 hours a day, seven days a week.

We offer heating and cooling repairs, maintenance, installations, and upgrades for year-round comfort. Our licensed plumbers handle diagnostics, repairs, replacements, and installations with upfront pricing, while our sewer and drain specialists work to restore flow and help minimize future water damage and inconvenience. Our licensed electricians take on projects large and small, including electrical system upgrades, EV charger installations, and backup generators. We also design, install, and service indoor air quality systems for homes and offices. For commercial properties, multifamily buildings, and property associations, we tailor our work to the property’s needs while prioritizing safety and minimizing operational disruption.

Our geothermal services include system installation, maintenance and repairs, upgrades, energy-efficiency assessments, and geothermal loop field design. We guide customers through the process from the initial assessment to installation and ongoing service, developing efficient systems that use the earth’s natural energy for year-round heating and cooling. As a Lennox Premier Dealer, we combine established products with more than three decades of practical experience. Flexible financing options are available, and our TOPTEC Home Care Club® provides another way to support ongoing comfort and peace of mind. Whether we are helping with a home, office, or larger property, we bring the same focus on reliable service and carefully planned solutions.
