"I just want to say how great they were!!! I called for my mother who had no heat and they came out the same day, at the time they said, went and got the part, and put it in the same day!!! I cannot say thank you enough for the service!!!"

"Mr. Koval is a professional. He is prompt and reliable. Twice, Mr Koval responded to emergency situations, and he dealt with the problems effectively. Today the water to my home had to be shut off due to plumbing problems in my laundry. After that was taken care of he took the time to fix my laundry doors! All this was done at a reasonable rate. I would recommend Mr. Koval without hesitation."
