“My AC unit was leaking the night before leaving for vacation. I was treated with respect, professionalism, and a fair price. I left for vacation on time with the comfort knowing my unit was fixed right. The repair person they had sent was Ben. I couldn't be happier with his work and friendly personality. Thank you very much. For those looking for a company. Please take this review to heart. Look no further.”

Air Conditioner Installation in Round Lake Beach, IL 60073

“I was originally told that installation would happen on Friday @ 10:00 a.m. CST; however, due to one guy calling in sick and another tech working another job, I didn't get assistance until Noon'ish. Paul (I think that was his name) was amazing – he did everything by himself and got the job done. He was pleasant and I made sure he had bottled water since it was so hot outside! He wore his booties, too. Thank you!!”
