Heat Pump Replacement & Installation
Bay Area's #1 Choice

Too old, too damaged, running on a refrigerant nobody can legally service anymore – that’s heat pump replacement territory. United HVAC, Plumbing & Electrical handles ducted and ductless replacements across San Jose, Santa Clara, and Cupertino, Belmont, Atherton, Menlo Park and other Bay Area cities start to finish: assessment through the final permit sign-off.

When Does a Heat Pump Need to Be Replaced Rather Than Repaired?

Three things push a heat pump toward replacement instead of repair: the refrigerant it runs on has stopped being made, the compressor gives out on a system already near the end of its life, or the repair bill starts closing in on what a new system would cost anyway. Age and refrigerant type tend to answer that question before price ever does.

Signs Your Heat Pump Has Reached the End of Its Service Life

A system running on R-22 refrigerant is the clearest sign – that refrigerant hasn’t been produced for years, and any unit still using it is already well past the point most Bay Area homeowners would consider replacing it. Carrier and Lennox ducted systems installed across South Bay homes in the 1990s are hitting this point in large numbers at the same time, which is why so many heat pump replacement near me searches these days trace back to the same handful of aging system models. Sometimes we see old General Electric units and even some units from the makers that don’t exist anymore. Of course, these units are to be replaced as you can barely find spare parts for them now. 

A compressor failure is usually the final signal, since replacing that single component rarely makes sense on a system already old enough to need it.

Repair vs. Replacement: How to Make the Right Call

R-22 systems settle this question outright – that refrigerant can’t legally be recharged if a unit develops a leak, since production ended years ago and remaining supply is both scarce and expensive. On a newer system running current refrigerant, a compressor failure is the next dividing line: replacing a compressor on a unit already twelve or more years old rarely pencils out against the cost to replace heat pump equipment entirely with a new one. We’ll tell you plainly which side of that line your system is on.

Heat Pump Replacement: How the Process Works

Replacement starts with a full reassessment, not a copy of what’s already installed – the old system’s sizing may not have been right to begin with. Most single-zone ductless jobs finish in a day; ducted whole-home replacements with a panel upgrade can run one to two days.

System Assessment, Equipment Selection, and Permitting

A Manual J load calculation gets run fresh, since the failing system’s original sizing isn’t assumed to be correct. The electrical panel gets checked against the new unit’s requirements – moving from an older single-stage system to a modern variable-speed inverter often draws more continuous load than the existing panel was built for. The permit and any required panel upgrade get sorted before the old equipment comes out.

What Happens on Replacement Day

The old outdoor unit and any indoor components being replaced come out first, with refrigerant recovered and the equipment disposed of according to EPA guidelines – R-22 in particular requires documented handling. The new system goes in, electrical and refrigerant lines get connected, and the whole setup runs through a full test cycle at both heating and cooling output before the crew leaves.

Heat Pump Replacement Cost in the Bay Area

$6,000 to $8,000 covers a single-zone ductless system. Push into ducted whole-home territory and heat pump replacement cost climbs to $16,000, sometimes $30,000 or beyond – tonnage and a possible panel upgrade are what drive that spread.

Factors That Affect the Final Price

System tonnage and zone count drive most of the cost difference between a single-room replacement and a whole-home one. A panel already sized for a variable-speed inverter keeps the job toward the lower end; one that needs upgrading adds a separate cost on top of the equipment itself. Ductwork condition matters too – usable existing ducts cost less to work with than ones needing repair or replacement alongside the new system.

Rebates and Incentives Available to Bay Area Homeowners

The Bay Area runs a wide range of rebate programs – San Jose Clean Energy, Silicon Valley Clean Energy, Peninsula Clean Energy, Eco Homes, BayREN, and others, each tied to different equipment and service territories. Funding shifts throughout the year, so the real number comes from the on-site assessment rather than a phone estimate. Some programs offer rebates outright; others pair with low-interest financing instead. A few clients have financed an entire $30,000 project between rebates and low-interest terms combined – worth asking a home comfort advisor what’s available before assuming the sticker price is the final number.
