Fred Petrus

Frederick S. Petrus, CPA, MBA

President and Chief Operations Officer

Owner and president, Fred Petrus has knowledge and experience in all areas of the business. You can feel good about hiring CFS Service because it is under the leadership of a Master HVAC tech, Master Plumber, Master Technician and a real estate professional. Plus, he holds a class “A” contractor's license, has an MBA and is a CPA certified to work in both Virginia and Maryland.

This wide range of knowledge and experience, plus a passion for doing things the right way means that CFS Service has the best leadership possible. Sit down and talk with Fred and you’ll realize how important great customer service is to him too. One of his biggest pet peeves is when companies use free repair call offers to get in the door with the goal of finding things to sell the customer and to pad the bill to pay for the "free" service call. This will never be the case at CFS Service. The free repair call tactic does not fit with the company values. Honesty is more than just a buzzword, it is the way we run the company.
