What is a dual-fuel system?
A dual-fuel system combines an electric heat pump with a gas furnace. In mild weather, the heat pump heats efficiently. When temperatures drop below the balance point (usually 35-40°F), the gas furnace takes over. Call (925) 578-3379 for a free Brentwood estimate — we serve all Contra Costa County neighborhoods.
Are dual-fuel systems worth it?
In Brentwood, dual-fuel can be an excellent choice. You get heat pump efficiency 90%+ of heating hours, with gas backup for the coldest days. This often results in the lowest annual heating costs.
Why Choose Professional Dual-Fuel Systems in Brentwood?
Brentwood dual-fuel installations address one of the Bay Area's most demanding climates for any HVAC system. Deer Ridge and Harvest Park properties with existing gas furnaces face the choice between a heat pump-only replacement that needs to perform at 105°F in summer and 32°F in winter, or a dual-fuel configuration that assigns each task to the equipment best suited for it: the heat pump handles the majority of the heating season at high COP, and the gas furnace handles the coldest events when heat pump output declines.
Brentwood's extreme climate means the crossover temperature calculation for the dual-fuel control is particularly important. At 32-35°F outdoor temperatures — which Brentwood experiences during January and February cold spells — the heat pump's heating COP has dropped to near 1.5, and the gas furnace becomes the less expensive heating option. Galaxy configures Brentwood dual-fuel systems with a crossover in the 35-38°F range, which captures the maximum heat pump efficiency hours while ensuring the furnace takes over before the heat pump is operating at a disadvantage. Vineyard area properties with newer construction and better insulation have lower crossover temperatures because the well-insulated envelope retains heat pump output more effectively at marginal temperatures.
Brentwood Climate & HVAC: Brentwood experiences some of the Bay Area's most extreme summer heat-temperatures routinely reach 95-105°F from June through September, with occasional heat waves pushing even higher. This makes powerful, efficient air conditioning absolutely essential for comfortable living. We recommend high-efficiency variable-speed heat pumps specifically rated for extreme heat performance. These systems deliver strong cooling during peak heat while using minimal energy during milder weather, providing year - round comfort with lower utility bills.
From newer developments in Deer Ridge and Harvest Park to established neighborhoods throughout Brentwood, the city's family-friendly housing serves East County residents and commuters.
