We finally had some rain yesterday, Labor Day weekend.YEA! My air conditioning quit working during the storm. This morning I called DND SERVICES first thing and being a holiday I was surprised they answered and within 90 minutes Colten arrived checked it out and replaced the thermostat and my house is cool again. This is not the first time I called these folks (it was the furnace last time) and they have always shown up and completed the job in a timely and courteous manner.
Darlene Stinnett
These folks are courteous and professional in every way. They did a complete replacement of an older unit in just one day. They even took care of a few things that were not in the contract at no additional charge. I will certainly use them again and you should too!
Bill Stiles
Honest, responsive, talented technicians. No hard sells and more than one repair has come in UNDER estimate. Highly recommend. Colton is the man!
