Best Environmental Services in Phoenix AZ

I was interested in changing from a 75 gallon gas water heater to a tankless gas water heater. Zippity employee, Devante, was scheduled to give me an estimate at my home. He arrived on time and evaluated my current 20 year old water heater. After discussing the water usage, Devante explained the unit he was suggesting and answered all my questions. After providing the written quote he was able to schedule the install the following day. He returned the next morning and completed the job within.the estimated time. Devante is very knowledgeable and professional. He completed a nice retrofit of the unit and had it up and running. I am very happy and highly recommend Zippity!
