COOL SAVINGS
Comfort that pays for itself
Enphase Air fine-tunes every degree using live data—solar, battery, rates, weather, even EV charging—to save you money.
Basic savings
Up to $55/year
In hot, sunny climates, Enphase Air pre-cools your home midday using surplus solar and lower-cost grid power, so your HVAC runs less when rates peak later in the day.
Combined savings
Up to $130/year
With a demand response program from your local utility, Enphase Air briefly adjusts your temperature when grid demand peaks, earning credits on top of everyday savings.
Ultimate savings
Up to $275/year
With an IQ Battery on NEM 3.0 in California, Enphase Air prioritizes storing low-cost daytime energy, making it available to help power your home when evening electricity rates peak.
Estimated average annual savings for homes with electric heating and cooling. Actual savings vary by climate, system configuration, equipment, utility rate plan, and local program availability, and are not guaranteed.
