Credential Your Contractors

Welcome to Commercial Insurance Services’ (CIS) national network of quality contractors. For over a 40-year history, CIS has worked with the insurance industry and our national network of contractors reviewing commercial and residential mechanical insurance claims.

Who is Commercial Insurance Services (CIS)?
CIS was established in 1978 and has been servicing the insurance industries ever evolving needs. We are not a warranty company. We do provide a valuable service to our clients in the form of consultation. Our objective is to achieve a high level of satisfaction by chartering our Network Service Contractor’s services to obtain factual, non-bias data when performing visual and diagnostic inspections. In addition, we also look to obtain pricing based on a scope of work outlined by CIS’ Consultant. CIS, utilizing our Network Service Contractor, may have the potential to produce work which had been inspected. All of the projects CIS is authorized to perform will be produced under our sister company, NHG.

Who is National HVAC Group (NHG)?
Over the years of consulting, CIS has been asked to perform projects that were consulted on by CIS. As such, CIS created their sister company, NHG. NHG facilitates all repair and replacement jobs captured during or after the CIS’ consultation phase. Due to CIS’ partnerships within the insurance industry, when authorized, NHG is the go-to in HVAC-R, Chiller, Electrical and more. NHG is currently expanding our footprint by targeting non-insurance related work such as new construction, restoration, temporary heating/cooling/electrical, general contractor networking, and many other areas where repair & replacement projects are needed.

Why Join Our Network?
CIS consults on thousands of insurance claims across the nation for over 120 different insurance carriers, in both residential and commercial markets. We have built our network over the years by having quality contractors, who are experts in their related field. We simply match our client’s needs with our Network Service Contractor who can perform the service requested. Whether it’s a service call, visual/diagnostic evaluation of equipment, or a repair/replacement; our success is measured by sending those requests to you.
