New Heating System in Brentwood: Written Estimate First

Brentwood is a mix of hillside canyon properties along Sullivan Canyon and Mandeville Canyon and larger flat lots on the Westside, many held by the same family for decades. Long private driveways, gated access, and narrow canyon streets are common, and they complicate equipment delivery and staging on a full system swap. Winters stay mild thanks to the coast, but canyon-bottom homes run noticeably colder overnight than open, sun-exposed lots nearby. That swing means your heating system needs to handle genuine cold snaps without being oversized for a climate that spends most of the year in cooling mode. We install heat pumps and dual-fuel systems sized to the specific lot and elevation, not a neighborhood average.

Many of Brentwood's older estate homes came with builder-grade furnaces ducted through attic spaces that bake in summer, some of them original to a house built decades ago. Replacing those units often means upgrading to variable-speed heat pumps that qualify for federal tax credits and cut your electric bill year-round. Homes with the oldest gas furnaces typically see the biggest efficiency gains when switching to electric heat pumps, especially with California's push toward electrification. We map your property's access, confirm electrical panel capacity, and coordinate crane or flatbed staging when your driveway is narrow, gated, or shared. If you need ductless for a guest house or detached office, check our <a href='/services/ductless-mini-split'>ductless mini-split</a> page for options that skip the attic run entirely.

California Title 24 energy code now requires all new heating installations to meet efficiency minimums tied to climate zone, and coastal Southern California zones like Brentwood's still require heat pumps to clear meaningful HSPF2 and EER2 thresholds even though winters here are mild. Gas furnaces must reach 80% AFUE or higher, but the 2023 update pushes builders and retrofit projects toward electric heat pumps first. If your electrical panel can support the load and your ducts pass leakage testing, a heat pump qualifies you for the federal 30% tax credit under the Inflation Reduction Act, up to two thousand dollars back on equipment and installation combined.

Most Brentwood homeowners replacing 15-year-old furnaces discover their existing ducts leak enough air to fail the duct test required by Title 24. We seal those leaks with mastic and foil tape, retest to hit the 6% leakage threshold, and document it all for the building department. If your panel is maxed out, we coordinate a service upgrade with an insured electrician before the heating install begins. Heat pump installations typically run eight thousand to fourteen thousand dollars depending on tonnage, brand, and whether ductwork needs modification. Sticking with a standard gas furnace replacement costs less upfront but misses the tax credit and keeps you on standard utility rates.
