“We had a new furnace/filter/humidifier/thermostat installed. Terry and PJ did a great job – neat, thorough, considerate. We had one issue: after they did their testing they apparently forgot to flip a switch on the gas valve and so after the showed us all about programming the thermostat and the furnace was seemingly working fine, they left and the furnace would not cycle back on. After I checked what I knew to do, and it still didn’t cycle back on, I called the after hours number and spoke to the on call person (whose named I failed to write down and now can’t remember) came right over, found the problem and corrected it. If you wonder at the 5 stars I rated them, I can only say that my clue that this is the company you want to work with is this: little oversights can always occur; what is important is the quality of the service recovery when those things happen. ESI was first rate.”
