Claim This BusinessAbout NG Air Conditioning
NG Air Conditioning brings over fifteen years of hands-on experience to Chicago-area homeowners, delivering licensed and insured HVAC solutions across Buffalo Grove and surrounding communities. The company maintains a flawless five-star rating derived from twelve client reviews, reflecting consistent delivery on repair, installation, and maintenance commitments. Beyond standard service calls, NG Air Conditioning handles specialized installs including ductless mini-split systems, heat pumps, and complete furnace replacements.
The contractor differentiates itself through a warranty structure uncommon among regional independents: six months on labor, one year on parts, and as many as ten years on new equipment installation. Their diagnostic fee of eighty-nine dollars dissolves entirely when homeowners proceed with recommended repairs, removing financial risk from the inspection phase. Every major HVAC brand receives service attention, and the team operates around the clock for emergency calls, ensuring a failed cooling system during a July heat wave draws a same-day technician visit.
Client testimonials specifically recognize technicians Vitaliy and Naz, with scenarios ranging from wasp-nest removal near a furnace core to compressor replacements completed within fifty minutes during ninety-five-degree temperatures. One homeowner reported a two-hour response window during extreme heat, restoring air conditioning in fifteen minutes. Another described clear post-service guidance answering follow-up questions after the initial repair concluded.
