Builder I purchased had this company install a tankless water heater . The unit has failed in the last year over 4 times . Everytime I called them for service they say nothing wrong but change a part in the unit. I had the exhaust vent leaking co2 in my basement for over a week and Daniel the owner I believe says its nothing wrong . I just called another company and they shut the unit down not safe . Now I have 4 kids and have to go my parents house again to bath them . Stay away from this company there dishonest and take advantage of people .
