Real reviews from Connecticut homeowners who made the switch to CPP.
"Many companies say they are the best, have reasonable prices and great service — but Billy and CPP is the real deal. Great service, great prices and very knowledgeable staff."
"We were Amerigas customers for 20 years. One call to CPP and I learned they'd been charging us almost $5/gallon when propane was at an all-time low! I switched and my budget went from $414/mo to $160/mo. Do yourself a favor!"
"From sales to professional service, it was a pleasure working with these people. Very friendly and they knew what they're doing."
