Air Conditioner Repair in Ingleside, IL 60182

“Our air conditioning failed on Friday early evening, extremely hot and humid and the weather forecast said it would be getting worse for Saturday. Called first thing on Saturday morning and Shane got to our house around 11. He had been to the house before.
We knew our 20 year old furnace was on borrowed time. Shane replaced the capacitor cleaned everything out really well and got it going. But about 10 minutes later it stopped. Nice try Shane.
Shane worked with the office and others and was able to give me a quote on a new furnace. It was very reasonable but couldn’t get done for 3 or 4 days. Now 2 senior citizens and an old dog were in the swamp without any air conditioning.
Shane told me he talked to the boss and that they could help us out with a couple window units in the meantime. He then went to finish some other jobs and returned with 2 window units he then installed. Everything was working, he left and our circuit breaker tripped. I called and he came back (again) and got us hooked up into different outlets/circuits. Shane was awesome in every way. Likewise, the fact that the folks at Miller’s were able to get us the window units is simply outstanding. We would’ve had to go stay with family or a hotel.
Millers really went out of their way on a really busy weekend, with temps in the 90s and humidity just as high. We really appreciate it. Thank you so much.”

Water Heater Repair in Mundelein, IL 60060

“I had a very positive experience with Miller’s Heating. I had called another company and the technician had no idea what he was doing it was very frustrating. The service man came to work on my issue and I was fully confident in his expertise. I wound up purchasing the service plan and a new water heater. I would highly recommend this company they are very responsive to your problems.”
