What is a HERS Rater?

H.E.R.S.  Stands for Home Energy Rating System.

A HERS Rater is a special building inspector who has been certified by the California Energy Commission to verify that California Title 24 Energy Standards are met by the installing contractor.
To find out more about HERS visit the California Energy Commission Website.  

What Tests and Verifications Does a HERS Rater Perform?

The Title 24 Building Energy Efficiency Standards apply to new construction, additions and alterations. Additions are changes to an existing building that increase the conditioned floor area and volume. Alterations that are not additions are changes to a building's envelope, space conditioning system, water heating system or lighting system.

HVAC Alterations

HVAC System Evaluations for Home Purchases

The heating and air conditioning system accounts for almost 50% of the energy used in a home and when it’s time to replace it the costs can run into the thousands of dollars. Having it tested and evaluated before you buy a home can save you a lot of grief and money later on. If you don’t have it tested…You’re just guessing..

When do You Need a Building Permit?

According to the California Building Standards Code, no building or structure may be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished unless a separate permit for each building or structure has first been obtained from the building official. Yes, that includes installing a new or replacement furnace, air conditioner, or ductwork. There are several different types of permits, based on the type of construction: structural, plumbing, mechanical, electrical and combination (used for single-family home construction and other small projects).
Code requirements vary in different cities. You may need to create plans to submit to the department, make a plot plan for your property showing the improvements, and show the type of construction you'll be using. We know what’s required by all the different city and county offices and for a small fee we can fill out all the forms and apply for your permits for you.
