Conrad P. did an amazing job - from the initial estimate to the actual install, the entire service was professional, efficient, and detailed. He took the time to explain possible causes, the reasoning for each, and the best path forward. He was courteous, mindful, and highly knowledgable. Communication was excellent and we especially appreciated that the same individual who did the estimate also was assigned the actual job. Highly recommended!

Unprofessional in handling phone calls.

This is the worst, non responsible company imaginable. They charge a fee for coming out, 40 minutes late for their appointment, then you never hear from them again, they have your $99.00 hostage. Not professional, not responsible, not worth it!

Charley came to my home and quickly repaired my a/c unit. He was very knowledgeable, pleasant, and put up with my dog. The cost was pricey for someone in my condo building, but you pay for what you get! I got a very skilled and nice professional. šIād give five stars, except for the price.
