Q. Will you install products such as a water heater or a faucet that I purchase elsewhere?
A. We will gladly install any product you purchase. While we’ll guarantee the installation of your product for one year, we can’t offer a guarantee on your product. If there is a problem with your item, you will have to contact the store where you purchased it or the manufacturer to discuss their warranty.

Q. What is your warranty?
A. We offer a one-year warranty on labor. Product warranties vary based on product, brand, and where it is purchased from.

A. Unfortunately, we can’t work on window units. They are not currently designed in a way which allows us to work on them.
