Been dealing with Gene from Millfair for everything when it deals to my home and family members. Always prompt courteous and never an issue getting the problem fixed correctly the first time. Do yourself a favor and deal with a technician that actually knows what he is doing.

do not let these people in your house unless you want to spend more than the cost of a new furnace as they replace part after part after part since they do not have a clue as to how to actually diagnose a problem
