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!!”

“Technician was very professional. Again, I had problems with appointment time. Apparently it was told to me and the time given. However it was never placed in the appointment book. This is getting to be a problem and I have to follow up with appointments”
