Electrical and HVAC Services in Chicago, IL

In Ireland in the late 1930s, John Heskin was hard at work learning the electrical trade. By 1941, he was a professional electrician in Belfast, working for Harland & Wolff. Those history buffs among you may recognize that name, as they were the ship builders that built the Titanic. Another 15 years later, and John found himself in Chicago, IL, leading his own electrical contracting company. He specialized in wiring single- and multi-family homes throughout the Chicagoland area.

John's son, Tom, got his start early, when he was still in kindergarten, installing plates on outlets and switches—usually with crooked results. His pay was a dollar a day, and .50 cents if he took a half day. That is all that it took to get the seed planted, and in 2002, Tom graduated from the Milwaukee School of Engineering. He now operates Brilliant Home Services, providing homeowners throughout the area with truly exceptional HVAC, electrical, and generator services, all completed by some of the finest technicians and electricians in the industry. His pedigree is evident in the high standards that he holds himself, his company, and his employees to.
