"Fabulous! We needed our water conditioner serviced and other company wouldn't touch it because they didn't install it and just wanted to sell us a new one. Rebecca scheduled us for the following day! Steve Venditti was great, has 20 years of experience and knew what he was doing. He spoke with the manufacturer and they decided what needed to be done. He had the parts on his truck and 4 hours later the job was done. $500 included parts and labor and service call. Very fair price and excellent service. Totally professional. Highly recommend."
