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!”

“Russell, our tech was on-time, friendly, skilled and professional. As he worked he made sure to keep the rest of the house clean. He kept the doors closed as he went in and out and used shoe covers. He explained the problem and resolution well, so that we could understand and coached us on future maintenance. The charge was as quoted. The finished results looks better than we imagined. We we use and recommend Miller’s again.”
