Title 24 HERS 1 Testing & Verification


When a new HVAC is installed in a new or existing home testing needs to be met to satisfy the California Building Code. If any component of the HVAC system is altered there will be local inspection requirements that must be met for compliance by a certified third party HERS Rater.

Infrared Scanning and "Blower Door" Analysis


Infrared scanning (thermography) is used to detect thermal defects and air leakage in building envelopes. By using infrared video and still cameras to measure surface temperatures we can determine whether or not a home is lacking insulation in areas that normally could not be detected. Thermographic scans are also commonly used with a "Blower Door" test. The blower door helps exaggerate air leaking through defects in the building shell. Such air leaks appear as black streaks in the infrared camera's viewfinder. Together, these two mechanisms work to identify escape points for unconditioned air, which detracts heavily from the energy efficiency of a unit. Cost of Service: $200.00

The Home Performance Assessment (HPA)


During the Home Performance Assessment we will conduct our Visual Inspection, measure building air leakage with the "Blower Door" inspection, measure duct leakage with the Duct Leakage Inspection, rate efficiency and performance of the heating and cooling equipment. We will also perform attic/crawl space and window inspections, all of which will build a comprehensive overview of the energy efficiency of your house, as well as identify the components that can be improved/replaced in order to optimize the homes energy efficiency. Within 7 days time, we will meet with you and review our findings in our HPA report (debriefing) which includes custom pictures of your home, measurements obtained and recommended upgrades that will optimize energy efficiency. The consultation takes 1-2 hours and we will answer any questions that you may have about the HPA report. We will layout recommendations on strategy to make your home more comfortable, healthy, safe and energy efficient as well as guide you in garnering the rebates and resources available to homeowners when moving forward with these retrofits. Because of the nationwide push for an increase in energy efficiency, umbrella funds like Energy Upgrade California have been implemented and are providing massive funds for rebates. If you have not already done so at this point, we will guide you in finding the rebates suitable for your location and home, so that your Home Performance Energy Upgrade is as affordable as possible! If you elect to move forward with a Home Performance Energy Upgrade, we will model your home’s energy potential (using approved computer software) and submit a rebate request form to your local utility company. Once the job is approved by the proper energy provider, we will install the energy upgrades and perform the required “test-out” to ensure that the energy measures were installed correctly. The test-out repeats most of the test performed during the test in but generally it is based on retrofits installed or upgraded to meet the rebate requirements.

Cost of Service: $250.00-$500.00 (varies based on size of house, number of systems, etc. Most houses $300.00)

Combustion Gas Analysis


Combustion Gas Analysis is usually needed when applying for local utility companies rebate programs. Lower Home Energy will, per requirement, test all gas appliances for gas leakage and carbon monoxide levels on gas units before and after project completion.



Cost of Service: $100.00

Estimated Timeline: 1-2 hours

Duct Testing


The duct test will confirm that the maximum duct leakage is within the guidelines. By testing the system and using a "fog test" as a visible aid to locate the leaks. Contractors or homeowners can reduce time required to seal the ductwork and avoiding sealing in the wrong areas.
Cost of Service: $240.00
