Frontier Utilities customer service is very good, easy to set up and would recommend to friends
I switched when I moved- my house is smaller, but my bill is bigger. Granted, my new house is all electric- but when combining cost of gas/electric from my previous home- it’s still more expensive.
The website and information on your energy plan is not easy to access and not all of the features work. Also upon further research, frontier is not very green friendly. the prices for my area are very affordable than the other options though.
