Find out where your home loses energy.
California Home Energy Wise provides AI-powered energy audits that identify efficiency gaps without pressure to buy. Get clear, actionable insights for your Sacramento home or business.
Six systems that shape your energy costs
Every area we audit has a direct, measurable impact on your home's energy performance. Understanding each one helps you make smarter, more confident decisions about where to invest.
Roof
Your roof is the primary barrier between your home and the Valley heat. Poor insulation value, aging materials, or inadequate attic ventilation beneath the roof deck cause heat to radiate into living spaces, forcing your cooling system to work overtime. We assess roofing condition, reflectivity, and the thermal boundary below to identify how much your roof is contributing to energy loss.
Ventilation
A poorly ventilated home traps heat, moisture, and stale air — all of which drive up energy use and degrade comfort. Inadequate attic ventilation causes heat to build up and transfers directly into your living space. We evaluate your whole-house ventilation strategy, exhaust systems, and attic airflow to ensure your home breathes efficiently and your HVAC isn't overcompensating.
Windows
Windows are among the highest-impact sources of unwanted heat gain and loss in California homes. Single-pane glass, failed seals, and west- or south-facing unshaded windows can account for 25–30% of heating and cooling load. Our thermal imaging pinpoints exactly where your windows are underperforming and whether sealing, shading, or replacement makes the most financial sense.
HVAC
Heating and cooling typically account for 40–50% of a home's total energy use. Aging equipment, improper sizing, dirty coils, and leaky ductwork all reduce efficiency and increase your monthly bills. We inspect your entire HVAC system — unit condition, duct integrity, thermostat behavior, and airflow balance — to identify where performance and savings are being lost.
Solar
California's abundant sunshine makes solar a high-ROI opportunity — but only when your home's energy load is optimized first. Installing solar on a leaky, inefficient home means generating power to offset waste rather than need. We assess your roof orientation, current energy load, and shading conditions so you know exactly what solar investment is justified and when it pays off.
Hot Water Source
Water heating is typically the second or third largest energy expense in a home — and often the most overlooked. Tank-style heaters lose energy around the clock through standby heat loss, and older units operating past their rated efficiency years cost significantly more to run. We evaluate your system's age, fuel source, efficiency rating, and usage patterns to determine where savings are available.
