Best Security Systems in Phoenix AZ

Horrible experience. My pilot light wouldn't stay light on my water heater. The technician came out and told me I need a new thermopile but that it couldn't be ordered because my 4 year old water heater was missing the serial and model number. Was told I need ed to spend $3000 for a new water heater.I watched a YouTube video and was able to do a factory reset. Solved my issue and took only seconds.Why didnt the technician reset it ? They charged my $70 for a service call and only wanted to upsale me. It was a simple fix that the technician should have been able to figure out himself. Stay away from these guys.
