We asked a legitimate HVAC and water heater question, and the President of the company responded with "Fuck off"

We were in need of a house re-pipe after moving in a few months ago, and Fred's estimate came in well below anyone else who took a look at what needed to be done. He and his team did an incredible job and were in and out of our house in no time at all. Not only did they complete the re-piping in two days, they put in several new fixtures for us and discovered (and repaired) several issues with our plumbing we didn't even know we had. I cannot recommend this company enough and would absolutely refer anyone I know to them for any plumbing needs!

Ky was the best, most honest repair man I have ever had. Not only was he prompt but he also gave me his professional and personal recommendations. 10/10. they came the same day, and fix the issues right away. Thank you 10000x

I am currently into a remolding project for my home, which entails a new kitchen and replacing flooring throughout the house. During the beginning stages of the project I hired a "certified" electrician who was dishonest, unreliable and moreover not qualified. Because of this I contacted CFS Services Inc and spoke with Mr. Fred Petrus. Mr. Petrus immediately listen to my existing problems with respect to the electrical work.
He assigned one of his top electricians to come to my house and assess the existing work, then base on the findings provided a sound plan to correct the previous electrician mistakes. CFS perform the work flawlessly, they corrected all the mistakes, as well as made sound recommendations which enhanced the project. When dealing with CFS I have found them to be straight forward, honest and their contractors professional. I highly recommend CFS as a company.
