Featured Review

Verified review from Google

I got home from work to learn we had no hot water. We called Reliance around 9pm. They had us set up with a tech to arrive the following morning. The tech showed up bright and early, identified the issue immediately and fixed our tank in minutes. Tech was polite and professional, made a stressful situation a breeze!
