Every summer, Sacramento homeowners brace for the same painful reality: air conditioning bills that climb higher than the temperature outside. If your cooling costs seem to grow year after year despite no change in habits, the problem likely isn’t how much you use your HVAC — it’s how efficiently your home uses the energy it consumes. A professional HERS rating in Sacramento is the most accurate way to find out exactly where your money is going and how to stop the waste.

Why Sacramento Energy Bills Keep Rising
Sacramento sits in one of California’s most demanding climate zones. Summer temperatures routinely exceed 100°F from June through September, and PG&E’s tiered pricing structure penalizes high-usage households — pushing the biggest consumers into the highest cost-per-kWh tiers. Add aging duct systems, degraded insulation, and equipment that was never properly commissioned, and you have a recipe for runaway cooling costs.
The frustrating part: most of this waste is invisible. Your thermostat doesn’t tell you that 25% of your cooled air is escaping into the attic before it reaches your living room. Your utility bill shows the result, not the cause. A certified HERS evaluation is the diagnostic tool that connects those dots.
What Is a HERS Rating?
HERS stands for Home Energy Rating System — a standardized scoring method developed by RESNET and required by California under Title 24. A score of 100 represents a typical 2006 code-compliant home. A score of 0 is net-zero. Lower is better. Most existing Sacramento homes that haven’t had energy upgrades score between 100 and 150.
A certified HERS rater from Express Duct Test performs on-site diagnostic tests and delivers the completed report the same day — no waiting, no paperwork delays.

7 Ways a HERS Rating Reduces Your Energy Costs
1. Finds Duct Leakage — the #1 Silent Budget Killer
California data shows the average home loses 20–30% of its conditioned air through duct leaks. A HERS duct leakage test pressurizes your system and measures exactly how much air escapes — giving you a precise percentage and a clear fix target. For many Sacramento homeowners, sealing leaky ducts is the single most impactful upgrade they can make. Learn more in our guide on uncovering hidden savings with duct testing.
2. Catches Refrigerant Charge Errors
A refrigerant charge that’s off by just 10% can increase your cooling costs noticeably and shorten your compressor’s life. HERS refrigerant charge verification uses calibrated protocols to confirm your system is within spec — something most routine service calls skip entirely.
3. Detects Airflow Restrictions
Insufficient airflow across the evaporator coil forces your system into longer, less efficient cycles. HERS airflow measurement verifies your system is actually moving the volume of air it’s rated for — and flags restrictions that are quietly driving up your bill.
4. Checks Fan Efficacy Against Title 24 Standards
California’s 2019 and 2022 Title 24 cycles introduced air handler fan efficiency requirements. An oversized blower operating outside the required watts-per-CFM range adds to your electricity bill every single day it runs. HERS fan efficacy verification catches this directly.
5. Reveals Insulation Gaps
Sacramento attics can reach 160°F in summer. Without adequate insulation between that heat and your living space, your AC fights a constant uphill battle. A HERS evaluation assesses your insulation levels and identifies whether your home meets California’s current energy standards — or is significantly underperforming.

6. Gives You a Prioritized Upgrade Roadmap
Instead of guessing whether to replace windows, add insulation, or buy new equipment first, your HERS rating in Sacramento delivers a data-driven list of improvements ranked by energy-savings potential. Every dollar you invest goes to the upgrade with the highest return.
7. Unlocks PG&E Rebates and California Incentives
Many California and PG&E energy efficiency rebate programs require documented HERS testing to qualify. Getting a HERS evaluation before undertaking upgrades ensures you’re eligible to capture every available rebate — reducing the net cost of improvements like duct sealing, new HVAC equipment, or attic insulation.

When Should You Get a HERS Evaluation?
- Before replacing your HVAC system — ensures proper sizing and fixes duct issues that would undermine new equipment
- When energy bills are consistently high — HERS testing diagnoses the root cause with precision
- Before listing your home for sale — a documented HERS score is a verifiable, bankable asset in Sacramento’s market
- After major renovations — post-improvement testing documents performance gains and confirms work was done correctly
- When a permit requires it — many Sacramento HVAC permits trigger mandatory HERS field verification before finaling
