Tom's Mechanical Systems

Tom Brust founded Tom's Mechanical Systems in Grayslake, Illinois, in September 2009, establishing a father-and-son operation that now serves Lake County communities including Gurnee, Waukegan, Libertyville, and Vernon Hills, alongside portions of lower Wisconsin and the Chicago metro area. With 21 verified reviews yielding a 4.2-star rating, the company holds proper licensing and carries full insurance coverage. Operating hours run Monday through Friday from 7:30 AM to 4:30 PM, with 24-hour emergency service available for after-hours dispatch. The business specializes in sales, service, and installation for both heating and cooling systems, targeting homeowners in the northeastern Illinois corridor.

What distinguishes Tom's Mechanical Systems is their commitment to transparent communication and rapid turnaround times. They offer same-day service for urgent situations, a notable differentiator when competing contractors quote extended wait times for parts. Their technicians provide detailed explanations of diagnostic findings and recommended repairs, guiding homeowners through the decision-making process rather than pushing unnecessary work. The company maintains competitive flat-rate pricing on seasonal tune-ups and provides free estimates for all new installation projects, backing their labor with a workmanship guarantee.

Customer reviews spotlight specific scenarios demonstrating the company's problem-solving capability. When Caitlin Cervac's entire AC unit required replacement during a brutal heat wave, Tom and Tommy completed the four-day installation in sweltering attic conditions without delaying the project. Doug Wisbey presented a cracked heat exchanger that another contractor wanted $4,000 to repair with a 30-day parts wait, Tom secured the component and completed installation within 48 hours at a significantly lower cost. Steven Hamilton, a tax professional, has relied on the company for both residential and commercial properties for years, citing Tom's willingness to go above and beyond on every service call.
