I have worked continuously with Energy StarServices for the last five to six years. I operate a property management company and they have serviced our HVAC systems, done electrical work, and a number of installs and repairs for us. I have found them easy to work with and professional. They have very good office support. They are good with processing work orders and invoices which tends to be problematic with most other companies. The communication is also great. I can communicate very well through email with them (sending invoices and such), and sometimes over phone if necessary. If there is ever a problem, they will fix it in the end. They are very dependable.
