Boiler Repair in Grayslake, IL 60030

“I called in the morning and received a really quick call back. A technician was at our house very soon after and identified and fixed the issue. Service from Miller’s is always great. I’m knocking a star off due to the continuing issues with our mini split and because I think the igniter (the problem with the boiler this time) was replaced just a few months ago – although I may be mistaken about that.”

Air Conditioner Installation in Lake Villa, IL 60046

“This was a follow-up visit from the initial Furnace & A/C install this winter.
Your Technician was great polite, professional & informative. When the A/C was installed it was really cold out, so he was back to fill the remaining R410 need. He also check the Furnace and change the filter. I’m so pleased that we are working with your company.
Thank you”
