The short answer

ArcticPoint HVAC Repair installs ducted and ductless heat pumps in Los Altos homes, each sized to the house through a load calculation. Bay Area rules don't force you to replace a working furnace, but gas furnaces made from 2029 must be zero-NOx, so planning ahead helps. The federal 25C credit has ended, so check BayREN and your clean energy provider for current local incentives.

Many Los Altos homeowners are looking at heat pumps as a way to heat and cool the house with one electric system. ArcticPoint HVAC Repair installs heat pumps in homes across Los Altos (ZIP 94024), about 20 miles northwest of our San Jose base. This page covers what a heat pump installation looks like for a Los Altos home, how local air rules affect the timing of your decision, and what to check on incentives before you commit.

Why a heat pump makes sense for a Los Altos home

The Santa Clara Valley has a Mediterranean climate with dry summers and mild, damp winters. That pattern suits heat pumps well. Winter nights get chilly, but they rarely stay cold for long stretches. In summer, the same unit runs in reverse to cool the house, so you don't need a separate air conditioner.

Inland and southern parts of the valley run noticeably hotter in summer than areas closer to the Bay. Even so, many Los Altos homes have warm afternoons that make cooling worth having, especially in upstairs bedrooms and rooms with west-facing windows. A heat pump lets you add that cooling while replacing an aging furnace, instead of buying two separate pieces of equipment.

How Bay Area air rules affect your timing

Under Bay Area Air District 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.

That does not mean you have to rip out a furnace that works. The Air District rules apply only when an existing furnace or water heater fails or is replaced. What the rule does change is planning. If your furnace is getting older, it can make sense to think through a heat pump now, on your own schedule, instead of deciding in a hurry on a cold night after a breakdown.

Water heaters fall under a separate rule, Rule 9-6. Its zero-NOx date for small water heaters was set for 2027, and the Air District Board is considering amendments in November 2026 that could delay it. If you are thinking about a heat pump water heater along with a heat pump for heating and cooling, check the current rule before you plan that replacement. We can talk through both at the same visit.

What a heat pump installation involves

Every house is different, so we start with the home itself rather than a standard package. A typical Los Altos installation follows these steps:

  • A walk-through of your current furnace, ductwork, thermostat and electrical panel
  • A load calculation based on your home's size, insulation, windows and layout, so the system is sized for the house instead of guessed
  • A review of options, including a ducted system that uses your existing ducts, a ductless mini-split setup, or a mix of both
  • Removal of the old equipment and installation of the indoor and outdoor units
  • Electrical work as needed, refrigerant line setup, and a new or updated thermostat
  • Startup, testing in both heating and cooling modes, and a walk-through of how to run the system

Choosing the right setup for your house

If your home already has ducts in decent shape, a ducted heat pump is often the most direct swap for a furnace and air conditioner. We check the ducts for leaks, damage and sizing first. A new heat pump connected to leaky or undersized ducts won't deliver the comfort it should.

Ductless mini-splits can be a good fit for homes without ducts, for rooms added on later, or for spaces that always run too warm or too cold. These units mount on a wall or ceiling and let you control each zone separately.

Electrical capacity matters too. Switching from gas heat to a heat pump adds electrical load, and some older panels need attention before a new system goes in. We look at this up front so it isn't a surprise on installation day.

Incentives and tax credits: what is current

The federal Energy Efficient Home Improvement Credit, known as 25C, covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date, so don't count on it when planning a heat pump today.

Local programs work differently. Bay Area homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in any quote.

We install and service heat pumps throughout Los Altos and nearby parts of Santa Clara County, including Sunnyvale, Cupertino, Santa Clara, Saratoga and Campbell. If your heating or cooling fails outright, we also offer 24/7 emergency service. That can help keep you comfortable while you decide on a longer-term plan.

FAQ

Common questions

Do I have to replace my working gas furnace with a heat pump?

No. The Bay Area Air District appliance rules do not require replacing working equipment. They apply only when an existing furnace or water heater fails or is replaced.

What changes in 2029 for furnaces?

Under Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when they replace a furnace after that date.

Will a heat pump keep my Los Altos home warm in winter?

The Santa Clara Valley has mild, damp winters, which is a good match for modern heat pumps. Proper sizing based on a load calculation is what makes the biggest difference in comfort.

Can I still claim the federal 25C tax credit for a heat pump?

No. The 25C credit covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date.

Are there local incentives for heat pumps in Los Altos?

Check BayREN and your local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before quoting it.

Can a heat pump use my existing ductwork?

Often, yes. We inspect your ducts for leaks, damage and sizing first. If they aren't a good fit, or a room has no ducts, ductless mini-splits are another option.
