Took Great Care of Me
Took great care of me. Evan was awesome. I had an issue with a whole-home water filter that was actively leaking. I originally had an appointment set up with a different company who came late and claimed it was going to cost me 1k to fix the issue. I called everywhere and got the runaround, but I contacted Bel O and, without hassle, they responded within an hour and fixed my issue quickly and efficiently. And it was a reasonable price and way below the price listed above the other place was trying to rip me off for.
