Diamond Certified


What to Ask References
Learn From Clients of Marin Home Energy Assessment Companies

All Diamond Certified home energy audit services, like all other Diamond Certified companies, have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a home energy audit service in Marin County and the greater Bay Area, you can have confidence choosing a Diamond Certified company.

Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

If you can’t find a Diamond Certified home energy auditing company in San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross and Belvedere or within reach, you’ll want to do some research on your own. If you do, it’s wise to call some references provided by your home energy audit service.

Remember, references provided by home energy audit services are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers.

If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.
