The short answer
PrimeAir installs ducted and ductless heat pumps in Menlo Park homes, starting with a room-by-room load calculation and a check of your ducts and electrical panel. Air District rules don't force you to replace a working furnace, and the federal 25C credit ended for installs after 2025, so we confirm current BayREN and local incentives before you decide.
If you are thinking about replacing a gas furnace or an aging air conditioner in your Menlo Park home, a heat pump can handle both heating and cooling with one system. PrimeAir HVAC Repair Service installs ducted and ductless heat pumps for homeowners in Menlo Park (94025), about 8 miles southwest of our Fremont base. This page covers how we plan an installation, what we check in your home before recommending equipment, and how current Bay Area rules and incentives affect your timing.
Why Menlo Park Homeowners Are Looking at Heat Pumps
A heat pump moves heat instead of burning fuel to make it. In winter it pulls heat from outdoor air and brings it inside. In summer it runs in reverse and works like a central air conditioner. For many households, that means one outdoor unit replaces both a furnace and an AC condenser.
Bay Area Air District rules are another reason the topic comes up. Under Rule 9-4, natural gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date. The rules do not require you to remove working equipment. They apply only when an existing furnace or water heater fails or is replaced. That gives you time to plan a switch on your schedule instead of during a breakdown.
What We Check Before Recommending a System
A heat pump that is the wrong size will short-cycle, struggle on the coldest mornings, or leave some rooms uncomfortable. We size equipment from your actual house, not from the size of the old furnace. Before we quote a system, we look at:
- Square footage, ceiling heights, window area, and which way the house faces
- Attic and wall insulation, and air leaks around doors, windows, and attic hatches
- Existing ductwork: size, condition, leaks, and whether it can carry the airflow a heat pump needs
- Your electrical panel and available capacity for a new outdoor unit and air handler
- Where the outdoor unit can sit with good airflow, reasonable noise levels, and easy service access
- Rooms that run hot or cold today, such as additions, converted garages, or upstairs bedrooms
Ducted, Ductless, or a Mix
If your home already has forced-air ducts in decent shape, a ducted heat pump is often the most direct replacement. We connect a new air handler or coil to your existing ductwork and seal or repair sections that leak.
Homes without ducts, or with additions the original ducts never reached, may do better with ductless mini-split heads. Each head heats and cools its own room or zone. Some homes use both: a ducted system for the main living areas and a ductless head for a hard-to-reach room.
We will explain the tradeoffs for your layout, including where the indoor units would go and how the line sets and condensate drains would be routed.
What Installation Day Looks Like
Most installs follow the same sequence. We protect floors and work areas, disconnect and remove the old equipment, and set the new outdoor unit on a level pad or wall bracket. Inside, we install the air handler or indoor heads, run refrigerant lines, and connect power and the thermostat.
Once everything is connected, we pull a vacuum on the refrigerant lines, check the charge, and measure airflow and temperatures in both heating and cooling modes. Before we leave, we walk you through the thermostat settings, filter location, and what normal operation sounds like. If a gas furnace is being removed, we cap the gas line safely.
Incentives and Tax Credits: What Still Applies
The federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date, so do not count on it for a project starting now.
Local programs may still help. Menlo Park homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change with each funding cycle, so we confirm the current offer before including it in a quote.
If you are also replacing a gas water heater, check the current rule first. The zero-NOx date for small water heaters under Rule 9-6 was set for 2027, and the Air District Board is considering amendments in November 2026 that could delay it.
