You shouldn’t have to worry about...

  • Dealing with multiple vendors and contracts for HVACR, plumbing and electrical. We offer product selection advice, installation, service, and maintenance.
  • Finding a qualified, licensed, insured and bonded team that is self-managed and knows what the heck they are doing. CFS Services has been around since 1965, and we have the credentials, expertise and fiscal backing to take on all of your commercial projects.
  • Technician not showing up, equipment that isn't the right fit, and poor installation techniques. Yeah, that makes us mad too. We keep our promises so you can keep yours, by operating with transparency, integrity and consistent follow through.
  • Having subcontractors hire felons and criminals to work on your job site. Not a problem with CFS Services, we do a full background check on all of our technicians.

Premier services you can count on.

I have personally worked with CFS Service Corporation for over fifteen years, and will still continue on every project whenever I can. CFS Service Corporation has always provided beautiful and excellent work at a very competitive price; their overall talent, competence and ethical behavior put them at the top of our list. They are very easy to work with and you don’t have many problems or issues. They handle it all, great if you use them for multiple trades.
