I would leave zero stars if I could. We have been customers for 14 years and every winter is a nightmare of miscommunications and nearly empty tanks. This winter, they decided that one of our tanks didn't exist and didn't fill it, even though it's been there the entire 14 years we have lived in the house. Set a date to come and look at it to make sure it was working correctly but didn't tell us we had to be home and then canceled the appointment, even though someone is ALWAYS home at our house. Said they sent an email but didn't. Now we have to "reschedule" a tank check. We will now be waiting 7 to 10 days for a refill even though we are supposed to be on autofill. The autofill option has never worked. Run away from this company. I am no longer sure who owns Quarles. I think it has been sold to a company called Superior, whose service is exactly as terrible as it was under Quarles. This review is for home-delivered propane to heat our home. read more
