Quality Electric, EV & HVAC Services in Northern Illinois

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. Another 15 years later, John found himself in Chicago, IL, leading his own electrical contracting company. He specialized in electrical work such as; electrical wiring and rewiring in homes throughout the Chicago area.

John’s son, Tom, got his start early, when he was still in kindergarten, installing plates on outlets and switches. His pay was a dollar a day. That is all that it took to get the seed planted. 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. His pedigree is evident in the high standards that he holds himself, his company, and his employees to.
