Whether you’re a homeowner or a business owner, we are committed to identifying leaks quickly and accurately.

If you have a central air conditioner or furnace installed or replaced, California’s Energy Code (Title 24) requires having your ducts tested whether it’s in your residential home or your commercial building. HERS Rating in So-Cal performs comprehensive duct testing that complies with state regulations. We offer a very extensive testing for your ducts that compliant with state regulations to ensure your system meets all legal requirements.

Duct leaks are very common in homes, and they are responsible for significant energy losses. If you have a Duct leakage, it will reduce the air quantity in a system and most times the efficiency in which it operates. As a matter of fact, if your ducts have more than 15% leakage they must be sealed or repaired so you can comply with California Standard Energy Code. Our equipment will locate your ducts existing leaks and fix any problems quickly so you will not have any long-term loss of money.

It’s easier to seal duct during new construction than in an existing house.

With our methods for testing ducts pressure, we can quickly identify leaks and assist you to remedy them efficiently. Our testing device for duct leakage is a diagnostic tool designed to measure the air tightness of a forced air heating, ventilating and air conditioning system.

We use a duct leakage tester to diagnose and measure the airtightness of forced (HVAC) air heating, ventilating and air-conditioning ductwork. The tester is calibrating the fan for measuring an air flow rate, and we also use a  device for pressure sensing to measure the pressure created by the fan flow. We use the testers on residential multi-family, single family, and commercial buildings that have a forced air delivery system for heating and cooling.
