    Just finished getting the HERS Test rating on my house. What an easy and cost-effective way to meet new regulations on HVAC ducting. I got a two hour window, the HERS Rater arrived on time, was friendly, clean, very knowledgeable, and proceeded in a very professional manner. Although they said it might take up to two days, I got my rating certificate via email the same day. Now I'm good to go and ready for my final inspection. We'll Done. Thanks HERS RATERS, LLC.

    We needed to have a Title 24 field inspection completed for our ADU project and Hers Raters came out on time and completed the Title 24 paper work within 24 hours. Excellent service and took the stress out of it

    The team arrived ahead of time. They tested the air conditioning installation thoroughly and recommended replacing filters more frequently. The guys were friendly and pleasant. I'd highly recommend them to everyone.

    Daniel Degesyan did an outstanding job. He is a true professional. He was so efficient and careful and completed his inspection of our new AC system in less than 30 minutes. I would highly recommend the use of this company for such services. They are first-rate!
