Our Customer Reviews

Real Feedback from Past Jobs!
Anaheim, Ca
"We had trouble with the hydronic (Hot Water Heating) system in our condominium. We called DIAL ONE. They sent out a technician that knew what we has doing. He ordered the special part and fixed our system so we would have heat. He used drop cloths under his ladder when he went into our attic and cleaned up everything before he left. We were very happy with the experience."

"We called this company at 7:00 am and they were at our home before 10:00 am. They worked very clean and told us of all the options and prices before any work was done. Terry, the serviceman, did the repairs and installed a new wireless thermostat so I now can control the heat in my bedroom the way I want it. Thank you"
