Jeff helped us out when our Air condition gave out and temps were high 80’s. My wife works from home and we have a 3 month old baby, we were in a real pickle. Jeff was super knowledgeable, quick and honest. Thank you Jeff for the help

Our air conditioner went out and Chris was out right away and got us back up and running! Amazing service and very professional at explaining everything he was going to do and what was wrong. Will definitely be using McHenry Heating & Air, Inc again if needed!
Had an overall great experience with McHenry Heating & Air today. AC went out last night and my call was retuned first thing this morning. Jason, our technician, was working on our AC unit by noon same day. He was knowledgeable, identified the problem quickly and came up with a solution on the spot. Every detailed was explained. Greatly appreciate the authentic and honest approach!
