New Heating System in Brentwood: Written Estimate First

Brentwood's coastal-moderated climate keeps winters mild overall, but canyon and hillside properties along Sullivan Canyon and Mandeville Canyon see colder overnight lows than the flats, and homes tucked into shaded canyon bottoms run noticeably colder after sunset than homes a half-mile away on open, sun-exposed lots. Many homes on the Westside are older estate properties where the original gas furnace has logged decades of service, often sized for a floor plan that later additions and remodels have since outgrown. Homeowners replacing older furnaces today face a choice: stick with gas or switch to a heat pump that qualifies for federal tax credits and meets California's push toward all-electric new construction.

Brentwood subdivisions on the Westside often include HOA design guidelines that regulate outdoor equipment placement and sight lines. Heat pump condensers sit outside year-round, so we confirm HOA setback rules and screening requirements before installation. Most Brentwood homes have attic or garage furnace locations with ducted returns, which makes retrofitting a ducted heat pump straightforward. For homes without existing ducts or with additions that never had heat, a ductless mini-split offers room-by-room control without tearing into walls. Our crews know the Brentwood Westside street grid, typical lot layouts, and compliance pull timelines at the city building department.

California Title 24 now requires new homes and major renovations to install electric heat or show compliance through a performance calculation. While existing homes can still replace a gas furnace with another gas furnace, many Brentwood homeowners choose an ENERGY STAR-certified heat pump to claim the federal 30% tax credit, capped at $2,000 per system. A complete ducted heat pump installation in a typical Brentwood Westside home runs $8,000 to $14,000 depending on system size, ductwork condition, and electrical panel capacity. Gas furnace replacement costs $4,500 to $7,500. Heat pumps cost more up front but eliminate the gas line and monthly gas service charge, and they provide air conditioning in summer without a separate condenser.

We size every system using Manual J load calculation, not by guessing from the old furnace nameplate. Brentwood winters rarely drop below freezing, so modern cold-climate heat pumps maintain full heating output down to 5°F outdoor temperature. All of our installations include a written estimate before we start, insured and bonded technicians on the job, and compliance documentation with the city. If you're unsure whether a heat pump fits your home, we walk the attic and electrical panel during the estimate and explain both options with upfront pricing for each.
