"Nathan, the owner of the company, responded quickly and made it a point to come to the house to determine the cause of water leak that was discovered. He was more than professional and communicated very well about the situation. He was able to determine the cause of the leak quickly and made repairs the next morning. His communication throughout the entire repair proceds was exemplary which was very much appreciated given the nature of the leak. Superior service!"

"Mike responded to my request immediately, set up an appointment to look at my job and give an estimate right away, and then completed the work in 4 days. Within 8 days of my call my new water heater was installed. The contract was clearly set out, and the work was very professionally completed exactly as per the bid. Mike was very friendly and easy to work with. He left the work area clean when he left. I highly recommend Mike and Jax Mechanical."

Comment: RO system is Watts Premeir and has been installed since 2021 in a newly built ADU. Last guest was 14 months and he didn't use RO. System now makes gurgling noise for about 15 minutes after use. No leaks and the drain hose has been cleaned. Noise still persists.
