New Heating System in Brentwood: Written Estimate First

This page is for Brentwood homeowners with a furnace that has failed, cracked or become too costly to keep fixing, and for owners deciding between a new gas furnace and a heat pump. Brentwood Air installs both and quotes both from the same visit.

A furnace sits in an attic, a closet or a garage in most of these houses, and where it sits changes the job. We look at the flue path, the return and the ducts it feeds before we name a price.

If you only need a repair, we take that call too. Heating Repair is a separate service, and we tell you plainly when repair no longer makes sense.

Replacement usually makes sense when the part that failed is expensive, such as a heat exchanger, or when the furnace has failed more than once. We lay out both costs so you can see where the line falls for your house.

Gas furnace replacement costs $4,500 to $7,500. A complete ducted heat pump installation in a typical Brentwood Westside home runs $8,000 to $14,000. The two figures are for different systems, and each one moves with the factors below.

The estimate lists the work by line so you can compare a furnace against a heat pump side by side.

Replacing a furnace or heat pump in Brentwood is permitted work through LADBS. Natural gas comes from SoCalGas and electric service from LADWP. Title 24 Part 6 can require duct sealing and a leakage test verified by a HERS rater on a change-out.

The install day ends with a startup check and a walk-through of the thermostat, the filter location and the shutoffs, so you know where everything is. Ask about a Heating Maintenance plan if you want the new unit looked at on a schedule.

California law requires carbon monoxide alarms in homes with a fuel-burning appliance, so the new furnace visit includes a look at yours. If you smell gas, leave the house first and call SoCalGas or 911 from outside.
