Honestly the only company I trust. I had issues with a previous company and DOC Heating and Cooling literally went above and beyond. The other company is suspected of damaging my unit. It's a long story, but DOC Heating and Cooling came and picked up an old unit for no cost out of my yard along with working in cold weather until late in the evening to make sure I had working heat for the freeze that night. Impeccable service, friendly, and trustworthy! They were also one of the cheapest quotes I found.t
