Marty is the best! Professional, hard-working and reliable. He has taken care of my home and my sons home since 2015. He installed a new boiler and A/C. and keeps them in perfect working order. Friendly and extremely reliable. He and his capable staff are the kind of men you can trust in your home to do the job. I love that it is a family business. Karen who answers the phone and schedules the appointments keeps you updated and communicates effectively and in a friendly manner. I will never use another company!

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.
