1st service tech was ok but fixed our problem asap. I was asking questions he was hesitant to answer which was annoying. I needed them to come back to follow up a noise I was hearing after the ac unit was fixed by first tech. Paul came out and was super helpful in all aspects including giving us home owners tips that we didn't know. Like servicing your gas heater prior to the season to avoid carbon monoxide issues and hosing down the outside of the ac units and even what type of filters to use in the house (all things we didn't ask about but he happily shared) he also provided more info about how's and whys of our ac unit which was more than the first tech. We will request Paul for any future needs from this company!
