What Our Client Says
Great Value Deal
Superior customer service and value. They gave me options and when I shared the details with another contractor doing a totally unrelated job for me, he said “Wow, that is a good deal for top of the line equipment
– Ben C. in Aldie, VA

Andy was very friendly and clear in describing every detail of the product (heat pump). The installer, Pat, was great.

On-Time Service
They came on time and did what they said and it’s been working ever since. No complaints.
– Binny U.
Professional and Thorough
Out of the four recommendations, we went with Millie’s because they broke down the problem and recommended we work on the a/c in stages. We chose them for this, despite the fact they were higher than one other pro. They were professional, on time, and if/when we need a/c work again I will look to using their services.
