CO Heating sent someone to address the problem I was having in an appropriate timeframe. Chad was friendly and professional. He communicated what he found and what he did to fix the issue. The job was completed quickly. I can't think of a thing they could have done better.

2/16/24 Routine maintenance today. My experiences with COHC&P have all been 5/5.
