One of the worst companies I've ever dealt with in my life.
I purchased a home, at closing found out the hot water tank was leased from Reliance. Seeing that we waited 5 months for closing and sold my other property, I had no choice but to sign off on accepting their terms.
After 6 months, we sold our house and wanted to transfer it to the new owner. They made the transfer difficult. We sold the property and after closing Reliance continued to take money from our account each month because the new owner didn't want to do auto payments from their bank account. I no longer owned the properties nor was using the hot water tank, yet Reliance said I had to pay the fee on the tank (for the unrelated home owners) until they signed the form.
We paid for 4 months at which point we got our lawyer involved to force the new home owners to sign Reliance demands. It's a complete joke, this company does not have good intentions. Sign or else. That's their moto. If you sell or buy a house with a Reliance product, it's better to get it sorted out before closing, because not matter what the case is, Reliance will take money from your account no matter what.
1 year later, we were purchasing another home, saw that the owner were tricked into signing a 10 year Reliance hot water tank contract and we walked on the deal because we knew it would be such a headache dealing with this company to resolve any issue.
