Miller’s Is Here to Support Your Family

Raising awareness of dementia and how it might impact someone's life is part of our employee training. Employees with further understanding of dementia will act in a more considerate way to support all clients and customers in a patient, kind, and respectful manner, thus allowing our valued customer the dignity of aging in place.

Our Answer to COVID is the Air Scrubber!

The Air Scrubber by Aerus, which is installed in an air duct, cleans bacteria, pet dander, viruses, dust, mold, volatile organic compounds (VOC), smoke, and other contaminants from both the atmosphere and surfaces. In fact, this technology was found to reduce 99.9% of the COVID virus within three minutes and on surfaces within seven hours!

Water Heater Replacement in Grayslake, IL 60030

“GREAT service! The service tech, Shane who came to evaluate my broken water heater was great. Very informative and answered all of my questions about the replacement. Then service tech Joe and his helper who came to do the actual replacement were great. Quick install and took the time to explain the operation of the new water heater. Both service techs very professional and nice people. Also the person in the office was great to talk to on the phone. I highly recommend Miller’s for everything. Great service. Amazingly quick response and turn around time.”
