Gas Furnace Maintenance in Lake Villa, IL 60046

“I received a call from Miller’s that Josh the technician was on his way around 11am. He arrived about 15 minutes later. He put on his booties and wore his mask and introduced himself before coming in. I showed him where the Furnace/AC unit was located. He confirmed he was going to do annual maintenance on both units. He got right to work and did all the maintenance including the outside AC unit. He was here for about an hour to service everything. He was thorough, efficient and polite. Everything went smoothly. Thanks Josh and the Miller’s team!”
