HERS for Heating & Air Conditioning jobsAs HERS raters we provide third party verification for home and business owners to test duct leakage, refrigerant charge and in some cases airflow and energy use. HERS verifications are also needed to complete building permits in certain cases. If you don't know which verifications you need, give us a call at 1-800-597-7153 and we can walk you through the process.
On January 1st, 2010 new Title 24, building code standards came into effect. HERS ratings are required in most cases to at least verify duct leakage or refrigerant charge. According to the California Energy Commission, the average duct system leaks 30% in CA homes. So if you are a home owner you want to make sure your system is not leaking and as a contractor you can tell customers that duct leakage will be verified by a third party to ensure quality.

How to find your climate zone
for commercial jobs climate zones do not apply
For residential jobs you will need to know the Climate Zone (CZ) your home/job is in.
To find your Climate Zone enter the address ( 411 HERS Rd. Title24 Town, CA) in the space provided above the map and click the goto! button . Once the map zooms to where your home or job is click the color area around the home. It will say Outline zn then a number. That number is your climate zone,
HERS tests are required in Climate Zones 2 and 8 - 16.
This map is from the Energy Maps of California.
For non-residential jobs the climate zone does not apply but jobs you will need a HERS rating if you meet requirements listed below.
