The short answer
A Hidden Hills home can move to heat pumps all at once or one system at a time. We evaluate each zone's ducts, capacity and electrical feed, recommend ducted, dual-fuel or ductless equipment, and confirm rebates with your actual utility before quoting.
Plenty of Hidden Hills owners are rethinking how their homes are heated and cooled. Gas furnaces are getting harder to replace under regional air quality rules, the climate here is mild in winter, and a heat pump can take over both jobs with one piece of equipment per zone. For a home that already runs two or three separate systems, the switch can be phased one system at a time. We plan and install ducted, dual-fuel and ductless heat pump systems in Hidden Hills, working from our base in Tarzana about six miles east. This page covers how we approach the conversion for larger homes and what to expect along the way.
Phasing the change across a large home
Converting every system at once is not required. Many owners start with the system in the worst shape, or the one serving the most-used part of the house, and replace others as they age. That spreads out the cost and lets you see how a heat pump feels before committing the whole house.
We document every system on the property during the first visit: age, condition, duct performance and electrical feed. That gives you a roadmap for converting the rest over time, with no guesswork when the next unit needs attention.
Options for each zone
Different parts of a large home can be served by different types of heat pump equipment. We choose based on the ducts, the space and how the area is used.
- Central ducted heat pump with a new air handler for wings with good ductwork
- Dual-fuel pairing with a gas furnace for zones where you want gas backup
- Ductless mini-split heads for guest houses, pool houses, offices or converted garages
- Multi-zone ductless systems for rooms the central ducts have never served well
- Variable-speed outdoor units that keep sound down near patios and outdoor living spaces
Ducts, airflow and electrical feed
Heat pumps deliver air at a gentler temperature than a furnace, so they rely on good airflow. Long duct runs, which are common in larger homes, need to be properly sized and sealed. We measure static pressure and check attic runs before recommending equipment, and include duct corrections when they are needed.
On the electrical side, each heat pump needs its own circuit, and backup heat strips add load. We check main and sub-panels for capacity and plan circuits for each system. Where gas heat is retired, the furnace gas line is capped safely.
How rebates work for a Hidden Hills address
LADWP residential electric customers can apply for Consumer Rebate Program rebates on qualifying heat pumps, with amounts based on SEER2 and HSPF2 ratings, and applications filed after the equipment is purchased and installed, within 12 months of purchase. Hidden Hills, however, is outside the City of Los Angeles, and many homes outside the city are served by Southern California Edison rather than LADWP.
So the first step is identifying your utility from your bill, and we confirm its current program before any rebate goes into a proposal. Federal incentives have also changed: the 25C credit covered heat pumps placed in service before December 31, 2025, and it is not available for new installations.
Installation and startup
Each system typically takes two to three days, depending on duct and electrical work. We coordinate property access ahead of time and keep other systems running so the rest of the house stays comfortable during the project.
Line sets are replaced or flushed, brazed under nitrogen, pressure-tested and evacuated. At startup we verify charge, airflow, defrost operation and backup heat staging, then configure thermostats for heat pump control. We walk you through the controls and show you what normal defrost cycles look like on a cold morning.
Keeping heat pumps efficient
Steady thermostat settings work best, since deep setbacks can trigger backup heat. Keep outdoor units clear of plantings, rinse coils when dust or ash builds up, and schedule an annual check for every system so small issues get caught early.
Filtration deserves attention too. Because a heat pump runs its blower for longer stretches than a furnace, it passes more of the home's air through the filter each day. During wildfire smoke events, that steady circulation helps, provided the filter is rated to catch fine particles and is changed before it clogs. We size filter cabinets for each system so you can run a better filter without cutting airflow.
