APS & SRP Rebate Qualification
Your audit is the paperwork that unlocks utility rebates and tax credits — we map every dollar you qualify for.
The energy audit isn't just a diagnosis — it's the key that unlocks money back. Both APS and SRP tie their largest efficiency rebates to a professional assessment, and the federal 25C tax credit stacks on top for the audit itself and the improvements it recommends. Our rebate-qualification service maps every dollar your specific home qualifies for, documents your existing conditions to program standards, and prepares the paperwork so you actually capture the incentives instead of leaving them on the table.

Why the Audit Is the Gateway to Rebates
Utility rebate programs exist to reduce load on the grid, and they're built to fund improvements that genuinely save energy — which means they want proof. A professional energy audit provides exactly that: a documented baseline of your home's current performance, measured leakage and insulation values, and a defined scope of recommended work. Without that documentation, the biggest rebates are simply unavailable.
This is why the audit pays for itself twice. First through the energy savings its recommendations produce, and second by qualifying you for rebates and tax credits that can offset a substantial share of the improvement costs. Homeowners who skip the audit and hire a contractor directly often miss incentives they were entitled to, simply because the baseline was never established.
APS Programs Overview
Arizona Public Service runs a portfolio of residential energy-efficiency programs. Historically these have included a Home Performance pathway that pairs a professional assessment with rebates on high-impact measures like duct sealing, air sealing, and insulation, alongside a rebate marketplace for efficient equipment such as smart thermostats.
APS also offers demand-based rate plans where the timing of your usage matters as much as the total, which changes which improvements deliver the most value. As part of qualification, we confirm the current APS residential offers for your address and identify which apply to the specific measures your audit recommends. Program details and dollar amounts change year to year, so we always direct you to aps.com to verify the live figures before you commit.
SRP Programs Overview
Salt River Project runs its own set of home energy programs, historically including home energy assessments and rebates for measures such as duct testing and sealing, insulation, shade screens, smart thermostats, and AC tune-ups. SRP also offers demand and time-of-use plans where shifting load away from the peak lowers your bill.
If SRP serves your home, we confirm the current program offers and match them to your audit's recommendations, then prepare the documentation you'll submit. As with APS, SRP's exact rebate amounts shift annually, so we verify what's live for your address and point you to srpnet.com for confirmation. For homes on an SRP demand plan, we specifically flag the fixes that reduce peak demand, since those savings are easy to overlook.

APS vs SRP: Comparing Your Options
Homeowners often ask which utility pays more. The honest answer is that it depends on your specific home, the measures you pursue, and each program's budget in a given year — there's no permanent winner, and most homes are served by one utility or the other rather than having a choice. What matters is capturing the maximum available from whichever serves you.
| Consideration | APS | SRP |
|---|---|---|
| Assessment-linked rebates | Home Performance pathway | Home energy assessment programs |
| Common rebated measures | Duct sealing, air sealing, insulation, thermostats | Duct sealing, insulation, shade screens, thermostats, AC tune-ups |
| Demand-rate savings | Available on demand plans | Available on demand/TOU plans |

The Federal 25C Tax Credit
On top of utility rebates, the federal 25C Energy Efficient Home Improvement Credit rewards efficiency work. A qualifying home energy audit is eligible for a credit historically worth up to $150, and the improvements the audit recommends — insulation, air sealing, and certain equipment — carry their own additional credits subject to annual limits.
We provide an itemized report suitable for your tax records so you have the documentation to claim what you're entitled to. Tax rules and credit amounts change, and eligibility depends on your situation, so we always recommend confirming current limits with a tax professional or IRS guidance before you file. The key point is that the credit and the utility rebates stack — you don't have to choose.
Demand-Rate Optimization
One of the most overlooked savings opportunities in Arizona is optimizing for demand charges. If you're on an APS or SRP demand or time-of-use plan, part of your bill is driven by your single highest hour of usage — typically a hot afternoon when your AC works hardest. The efficiency improvements your audit recommends don't just cut total usage; they lower that peak, which can reduce demand charges directly.
We analyze your rate plan alongside your audit findings and flag the measures that most effectively shave your peak. For many homeowners this is found money — savings sitting in the structure of their bill that they never knew how to capture. It's a core part of how we help you get the maximum return from both the fixes and the incentives.
