We not only feel like we have made a smart decision, but we truly feel cared for due to Zack J. Thanks again, Zack, for everything.
Britny Doole
We had a great visit with Vee
We were serviced by Vee and her “co-worker” Waco Flaco. Waco Flaco was a great listener. He sat quietly and never interrupted. Vee, on the other hand, oh my goodness, we couldn’t get her to be quiet! 😂 All this is in jest. We had a great visit with Vee. She did a very comprehensive inspection and gave a clear explanation of options for us. We chose to have the ducts cleaned and also install an IAQ system after seeing the pictures of our duct work. She is friendly, very professional, and the entire visit was great. We enjoyed meeting her and her “co-worker” and look forward to seeing her again when she installs the IAQ system.
