I used HomeStars to suggest/find contractors who could replace my rented tank water heater with a purchased tankless unit for a 4-bedroom, 2.5-bath house. Ali contacted me soon after submitting the request via the HomeStars site, text message, and voicemail. I was very pleased with the prompt initial contact, the quick scheduling of an on-site visit, and then subsequent installation of the new unit. It was a relief to hear that a tankless unit could be installed in our un-finished basement that has no frames or drywall.
We agreed on a Navien 210-series unit which may be a little more than what we needed from what a flow-rate perspective. Yet, we will be ready if there was a higher demand for hot water at a single time, such as having visitors over who are using both showers simultaneously. Based on a message from Ali before installation, I thought we would be getting the "A" unit installed which has an integrated circulation pump included, but the "S" unit (210-S) was installed. I didn't notice until after a few days, but it has still worked great and can get hot water to the washroom furthest away within about 20 seconds of running the hot tap on, and did not deem it necessary to bring it up as it is working exceptionally.
I should point out that the original installation date was pushed back by a couple of days due to unforeseen events taking place. Ali was forthcoming, apologetic and quick to schedule a new installation date.
Also, Ali and his team helped with the removal of the rented tank and for the return of the unit to the appropriate location. Those who read this should be aware that contact should be made to the rental company in advance and to have paper documents prepared so that a seamless return can be made and that your rental charges will be pro-rated as early as possible,
I was also very surprised and happy that Ali and his group also changed the gas line going into the furnace while doing the line for the water heater. He walked me through all the connections and operations for the water heater while his team were cleaning up around the work area. He also gave good advice about some future considerations when it comes to HVAC such as the furnace in the house.
In the month that has passed since having the tankless water heater installed. My family and I are very happy with the results. Continuous supply of hot water throughout the house and not having to worry if there will be enough hot water for when I take my shower if I'm the last one in. I will definitely give Ali and AZ System strong consideration down the road for future projects such as replacing/maintaining the furnace as I was very happy throughout the entire process and the results using the new tankless unit for a month now.
