Michelle from Windsor gives us her feedback on her experience with Reliance:

Our Hot Water Tank suddenly stopped working the night before a big party was planned. I was frantic!! I spoke to agent ALEX first thing in the morning, he listened to my concerns and was able to get a technician out that same day! Our hot water tank was fixed with no glitches and our party was saved! Thank you RELIANCE for your great service!!!"

Windsor residents Barb & Greg Loebach give us their feedback on their experience with Reliance:

"The two guys, Mark & Mike, were on time arriving at our home and dead nuts on time with their estimated completion time....very professional, organized, courteous and skilled.... the entire experience starting with Dan, to the completion with Mark & Mike, was efficient... I have no complaints whatsoever and would recommend Reliance services to anyone."
