Air Conditioning Gajic Chicago HVAC Engineering

Air Conditioning Gajic Chicago HVAC Engineering operates as a family-owned contractor serving the Chicago metropolitan area with recorded credentials and verifiable customer feedback. Eight client evaluations posted to reputable directories consistently award five stars, documenting completed projects spanning residential lighting conversions, electrical service upgrades, and new construction builds across neighborhoods including Wicker Park and the North Shore. The company maintains standard weekday and Saturday availability from 7 AM to 7 PM, with Sunday hours extending from 9 AM to 5 PM for urgent matters.

What distinguishes this contractor from generalists lies in their dual capability spanning both custom residential lighting design and structural new development. Client testimonials reference LED fixture conversions requiring specialized engineering, electrical panel upgrades meeting current code requirements, and full building construction for single-family residences and multi-unit condominiums. The team executes projects at quoted prices without undisclosed charges, with multiple reviewers noting completion timelines shorter than initially estimated by competing bids.

Several named technicians appear across client narratives handling distinct scenarios. One reviewer documents a complete LED lighting conversion where the crew delivered a written estimate and commenced work within seven days, finishing the entire upgrade in two days. Another client describes custom lighting installation for a North Shore property alongside a full electrical service increase, completed to specification without callbacks. Multiple five-star reviewers specifically recommend the team for future electrical and building projects, citing responsiveness maintained over periods exceeding fifteen years.
