The team at Controlled Heating and Cooling is superb! Day before Thanksgiving we had found out our furnace was broke. Marty came out and investigated late that evening to find out the issue. We loved he was pet friendly, wore a mask and was down to earth! Great company! Services: Heating system repair, Heating system maintenance, HVAC system maintenance

Report
We called them for furnace repair as we had a unit that would occasionally not turn on. They spent 5 hours on site and when they finished the furnace did not work at all. The tech then demanded payment with no explanation as to what the stat of the furnace was and threatened to call the police when questions were asked. Bunch of con-artists, don't let them in your house.
