Poor Service, never returns you calls, sold me an Aquastat for my indirect boiler tank that didn't fix the issues we were having and then wouldn't take the part back and refund me. I called and left messages for 4 days straight and when I finally got ahold of him he said he is a busy man...really! In comparison when I called Canyon, he returned my call in 2 hours, came out and fixed the issue the next day and replaced the components on the boiler tank that actually needed to be fixed. Looking for a boiler expert, call Canyon.
