Performing Jobs FAQs

What happens if I fail my FQC?

Field verification failures will trigger corrective actions. Build It Green will communicate required corrective actions, timing, and documentation protocols required for resolution. Failure to resolve corrective action requirements in the specified timeframe may result in disciplinary action, including increased sampling rates or potential suspension.

How can I find out the results of Build It Green’s Field Quality Control inspections?

Results of completed field verifications are emailed to contractors from Build It Green FQC within days to weeks of the field verification. For more information on completed field verifications, contact Build It Green FQC at (510) 590-3360 ext. 607.

PG&E called my customer to set up a time to inspect the job. Is this a legitimate call?

Yes. PG&E will randomly select and inspect 10% of Home Upgrade applications submitted through PG&E’s rebate processing system. Inspections conducted by PG&E’s Central Inspection Program (CIP) are mandatory. Homeowners can also call the Residential Customer Service Center at (800) PGE-5000 or (800) 743-5000 to verify that the field inspector is an authorized PG&E employee.

How frequently will my company’s jobs be verified in the field?

Field verifications are performed on completed jobs to obtain a representative sample of your company’s work. Separate sampling tiers are established for each contractor and rater based on job performance in accordance with the Home Upgrade program guidelines. For more details on the sampling tiers, see Table 8: Field Verification Sampling Tiers in the Home Upgrade Program Participant Handbook.

How soon after I perform my pre-installation home performance assessment must I complete my post-installation home performance assessment in order to qualify for a rebate?

Participating contractors will need to complete the job within 45 days of their first assessment or risk losing rebate funds reserved for their job. If more than 45 days pass after the pre-installation home performance assessment, participating contractors or raters may need to resubmit the job.

Can the scope of work change after a job has been authorized to proceed by Build It Green?

Yes, the purpose of the pre-installation review is (a) to allow for a pre-installation verification and (b) to confirm that the home and proposed scope of work qualify for the Program. Changing the scope of work after the job has been authorized to proceed is common and acceptable in this program, as long as the post-installation documentation reflects the actual installed measures rather than the proposed upgrade measures. Keep in mind that the final modeled energy savings (and therefore the final rebate value) will be determined by the actual installed post-installation conditions of the home.

Are heat pumps eligible?

For Home Upgrade, heat pumps only qualify for the air conditioning measure if the existing system was a heat pump.

When do we call a gas service representative (GSR)?

In instances where an appliance fails the CAS testing, the participating contractor or rater must call a PG&E or SoCalGas GSR, per Whole House Action Guidelines requirements. To schedule a GSR inspection, call PG&E’s Central Inspection Program (CIP) at (800) 813-1975 during normal business hours or the PG&E Smarter Energy line at (800) 743-5000 for 24-hour service. SoCalGas can be reached at (800) 427-2200. The most current version of the Whole House Action Guidelines will always be on the Home Upgrade website Installation tab.

Where do I test for ambient CO on a furnace?

Ambient CO is tested at the supply grill closest to the furnace and within 6-12 inches in front of or around the appliance.

Do I have to test sealed combustion appliances?

Yes. You will need to test for Worst Case Depressurization, gas leaks, and ambient CO. (Even if the unit is in a vented attic, it will still need to be tested.)

My rating company has multiple BPI-certified HERS Whole House Raters employed. Can I send one rater to complete the test-in assessment and a different rater to complete the test-out assessment?

Yes, you may send different HERS Whole House raters to complete testing on a home if each rater is also BPI certified or if the rating company is BPI accredited and the professionals performing the tests have taken the Advanced Technical training.

At which points during the upgrade does a CAS test need to be performed?

Per BPI standards, Advanced Home Upgrade requires test-in and test-out CAS testing for ALL combustion appliances. Build It Green will not authorize any work without this test.  For more information, refer to the Whole House Combustion Appliance Safety Test Procedure and the Participant Handbook. The most current versions will always be on the Home Upgrade website Installation tab.

What documents do I need to submit jobs?

Refer to the Advanced Home Upgrade Desktop QA checklist for guidance. The most recent version will always be on the Home Upgrade website Submitting Jobs tab.

When do I need to get a signed contract?

A contract must be signed before installing Home Upgrade work. Consult the CSLB for more detailed information on contracts.

Do I need to have an energy audit performed on a home before starting a job?

Yes, an audit in compliance with HERS II standards must be performed by a participating Home Upgrade rater for Advanced Home Upgrade. Once the scope of work has been determined and before the installations have begun, a test-in assessment must be performed – this assessment can take place up to 120 days before work is started.

Program Info FAQs

Do customers still qualify for this program if they participate in Community Choice Aggregation (CCA)?

PG&E manages transmission, distribution and delivery of a CCA customer’s electricity, including providing meter reading, billing, maintenance and outage response services. Additional PG&E services, including energy efficiency rebates, California Alternative Rates for Energy (CARE), medical baseline, balanced payment plans (generally only on PG&E delivery charges), net metering, California Solar Initiative, other solar programs, and some demand response programs, as well as programs such as eBills and Automated Payment Services are still available to CCA customers. Programs administered by the CCA may differ from those provided by PG&E.

Can a homeowner in the PG&E territory participate in this program if that home uses propane?

PG&E electric customers who use propane to fuel items within their home (stove, water or space heating) are eligible for rebates for electric savings through the Home Upgrade pathways. Mobile homes on a chassis and axle constructed under HUD codes do not qualify. Please refer to Program Guidelines for Electric Customers with Propane Gas Appliances for more information.

What types of properties are eligible for the program?

Advanced Home Upgrade allows for single-family detached homes as well as 2-4 unit homes. Mobile (modular) homes may qualify for the program are on foundations (no axels or chassis), and have PG&E service IDs.

Can a PG&E customer install their own upgrade and apply for rebates?

A homeowner must work with a participating contractor to qualify for rebates.

Are solar energy upgrades eligible for Home Upgrade?

No, but solar incentives may be available through other statewide and local programs. Visit PG&E Incentives for Clean Energy to learn about PG&E solar incentive programs.

Can a PG&E customer receive more than one rebate for the same measure?

No.  “Double-dipping” refers to homes that are eligible for multiple rebates from PG&E. PG&E will not pay a homeowner twice for the same upgrade.

What if the PG&E customer only receives one utility from PG&E (e.g., Modesto Irrigation District or SMUD)?

If PG&E provides natural gas service to the home, but electricity is obtained from a utility provider other than PG&E, or vice versa, PG&E will pro-rate the rebate according to the proportion of total savings attributable to natural gas.

Who will issue the rebate check?

PG&E issues the rebate check, which may be issued to the homeowner or contractor. If the rebate is assigned to the contractor, a Customer Incentive Payment Assignment Form will need to be completed and submitted. Build It Green submits the rebate application to PG&E, which initiates the rebate check process, but Build It Green does not issue checks. Checks are processed in 6-8 weeks upon final approval by PG&E.

How much will the homeowner’s rebate be?

Advanced Home Upgrade rebate values are determined by the modeled energy savings achieved by the upgrade and are listed below.*


10% savings:$550 30% savings: $2,500
15% savings: $850 35% savings: $3,000
20% savings: $1,150 40% savings: $3,500
25% savings: $1,450 45% savings: $4,000


*After the $4,000 rebate is achieved, it may be possible to receive a higher rebate up to $6,500, depending on kicker incentives received for kilowatt and therm savings. These savings will be automatically calculated when submitting applications. Note that the estimated post-installation energy savings that you model before work begins may not match the simulated energy savings modeled based on actual post-installation measures. This can happen if the scope of work changes during the job or if test-out results are different from what you expected to achieve.

Why should homeowners participate?

Homeowners participate in this rebate program for many reasons including improving the comfort of their home and saving money on their energy bills. We leave it up to the homeowner and the contractor to decide if this program is right for them.

What is a Participating Rater and what is their role in the Program?

  1. Raters fill a gap between contractors who have a BPI BA on staff and contractors who do not. Raters are hired by contractors to perform test-in/test-out and CAS testing if they do not have an appropriately trained individual on staff. To participate in the Program, raters must meet these minimum credential requirements:
    • HERS II Whole House Rater certification
    • BPI-Building Analyst certification
    • Completion of Home Upgrade Advanced Technical Training
    • Home Upgrade Core Technical Training recommended but not required
  2. In addition to these credential requirements, Raters must also comply with the following program requirements:
    1. Execute the Rater Participation Agreement, including all supporting documentation
    2. Participating Rater must perform diagnostic assessment test-in, test-out and combustion appliance safety tests

What is a Participating Contractor?

Participating Contractors have been selected by Build It Green and specifically trained to deliver Advanced Home Upgrade. Participating contractors have met required qualifications to be part of the program and joined the ranks of Home Performance professionals who are experts in energy efficiency. All Participating Contractors have a valid California contractor’s license, appropriate bonding, and have specified certifications and/or training for the work being performed in the “whole house” concept and the comprehensive building science diagnostic assessments.

Who is eligible for Home Upgrade rebates?

PG&E customers with at least one energy fuel supplied by PG&E (electric and/or natural gas). In regions where Southern California Gas supplies natural gas the gas portion of the rebate is paid by SCG. In regions where electricity is supplied by another entity (eg. SMUD) the rebate is pro-rated for only the fuel supplied by PG&E.

What is the duration of the Program?

Funding comes from utility customers under the auspices of the California Public Utilities Commission. Incentives are offered on a first-come, first-served basis and are effective until funding is expended or the program is discontinued. Programs may be modified or terminated without prior notice.

Can a PG&E customer participate in Home Upgrade more than once?

Yes, as long as the scopes of work for each project are different.

Is there a waiting period after the test-in assessment is completed?

Once the test-in documentation has been submitted, contractors are advised to wait for approval of the Pre-Install application to be issued before starting the upgrade work. Contractors confident that the job qualifies can proceed with work without Build It Green approval at their own risk.

How can I check the rebate status for a job?

You will receive Notice to Proceed and Rebate Approval emails upon your job reaching these stages of approval. For final PG&E approval status, please call or email Build It Green.

How long does it take to process my application?

There is no typical timeline for a rebate to be processed. Once submitted to Build It Green, an application undergoes Desktop Review, where the application is reviewed by Build It Green’s internal review team. If there are no corrections to be made, the application is sent to PG&E for review before final approval. There may be required field quality control inspections from either or both Build It Green or PG&E that may delay the approval process, and in that case both the contractor and homeowner will be notified.

What documents do I need to submit?

For Advanced Home Upgrade applications are submitted in two stages, first as a pre-installation and second as a post-installation.
