My heat went out in November, I made a claim through AHS, and they dispatched Robert. My service was excellent! Robert communicated at every step. Luckily it was a pretty easy fix. Robert ordered the parts and installed them as soon as they came in. My furnace has been working fantastic ever since.

Report
Mill Creek Mechanical has gone above and beyond to service our heat pump. Robert's service has been prompt and he has communicated with us every step of the way between returning phone calls, part ordering, assessment of the unit, and working with our home warranty company. He even came out on a holiday and called to follow up with us a few days later to ensure the unit was working properly. Highly recommend and will definitely give them our future business!
