A&J Heating & Air Conditioning

A&J Heating & Air Conditioning has earned a 4.9-star average across 80 verified reviews in Lansing, Illinois. The family-operated business provides residential heating and cooling services throughout the greater Lansing area, responding to emergency calls with same-day or next-morning appointments. Technicians arrive on time, assess problems thoroughly, and explain repair options before proceeding with any work.

Reviewers consistently praise the responsiveness and transparency of lead technician Ulysses, who replied to emails within hours and arrived at homes the very next morning after initial contact. Multiple customers mention same-day service during critical situations, including a gas leak discovered in a kitchen and an air conditioner that stopped blowing cold air entirely. The team identified multiple gas leak locations beyond the initial inspection point, completed repairs the same morning, and ensured the home was safe and comfortable before leaving.

Homeowners who switched from longer-term service contracts report high satisfaction with the level ofdetail provided during diagnostics and the honest approach to repairs. One reviewer specifically notes the technician was described as honest, personable, and fast-paced during the entire service call. The Saturday hours until 1 PM accommodate working schedules, and the business has handled emergency water heater installations with same-day turnaround when parts arrived quickly under warranty.
