I saw all the good reviews of Shane, the owner of this company on line and was tired of the overcharging that all the other companies I have used before. Shane told me my coils were leaking and said I could either use stop leak or get new coils. HE suggested that he might call and see if possibly the part might be under warranty. IT WAS! Thanks to Shane I saved $600.00. His is very courteous and honest. He has won my A/C business for life.
