Air Conditioner Maintenance in Round Lake, IL 60073

“Shane is absolutely amazing. From the minute he showed up he was nothing but professional. After walking through everything before he started work I felt absolutely comfortable with him and knew the service was going to get done right. He even helped me identify another issue I was having in the basement and I was able to get it repaired quickly. He walked me through everything he completed and showed me a possible future issue with my compressor. I just moved here from Virginia and am so impressed with Shane that Miller’s will have my business for the three years I am here (I’m military). You guys have an outstanding technician in Shane.”
