FES is a Service &
Solutions Business

Selling a product is never our main goal



Our goal is to increase efficiency

  • Unlike many companies out there, we'll never push our product as the only solution to your problem
  • Our recommendations are always based on data, not commission
  • Our modeling and simulations give a clear idea of what to expect from a retrofit, if followed as outlined

We don't make wild claims

  • Our work is done with service in mind, on behalf of the homeowner at all times
  • Our passion is energy conservation and efficiency (sustainability makes sense!)
