Western Air Systems Certification's Mission Statement is To provide accurate HERS information, training, technical field and administrative support for our HVAC Customers.

Western Certification provides the right test for each application and does so accurately, extremely cost competitive, and in a timely manner.

Western's founder Ralph Coleman, is a former HVAC industry professional with over 35 years experience.

Our staff includes a former HVAC Service Manager, two dedicated HERS Raters, one with over 4,00 certifications, and an Office Administrator.

Western Certification is fully insured, for both our protection, and your protection. In addition to general liability, and vehicle insurance, we hold a policy dedicated to Error and Omissions, usually carried by law firms.

Vehicles and field staff are easily identified, and both are equipped with state of the art testing and communication technology.

Nothing is complete until the paperwork is completed; and this is where Western Certification excels.

Whether you choose to have us manage all your form from the CF-1Rs to secure your permit, or you select our web-based HERS program.
Take a quick tour of our web-based HERS program, and see how this program makes HERS testing easier. 

Document processing is handled by our administrative staff with electronic communication to you culminating in a "worry-free" process for you.
We are able to provide references from both large a small HVAC companies who look to us for these professional services.


We look forward to serving you soon!
