Gas Furnace Maintenance in Grayslake, IL 60030

“During the maintenance check up, I mentioned that my furnace sounded like a tornado whistle. Josh worked on it and quickly informed me it needed a new diffuser. That done, the furnace decided not to work at all and it needed a gas valve. Now I began to wonder if Josh was a jinx or what. But after explaining things to me, I was glad he discovered problems that could be fixed now preventing a furnace shutdown in the middle of the night on the coldest night of the year because that is how it would have happened for me. Miller has always been a company I feel I can rely on and a company who is honest. Hard to ask for more than that but they are also very nice and friendly!”
