Examples of our work
Is it time to replace your AC?
Replacement is worth pricing when several of these are true:
- The system is about 10 to 15 years old or more.
- It has needed more than one repair in a short time.
- The repair quote is large compared with the value left in the system.
- Your energy bills have climbed without a change in how you use it.
- Rooms cool unevenly, or the system runs constantly on warm days.
- It uses R-22 refrigerant, which is no longer produced and is costly to recharge.
No single item decides it. We look at age, what failed, repair history, efficiency and comfort together, and give you a repair price and a replacement price side by side.
How a San Jose AC replacement works
- We look at your home, not only the old unit. We check the existing equipment, the ducts, the attic or crawlspace, the electrical panel and where the equipment sits.
- We size the system. Capacity should come from the home's size, layout, insulation, windows and sun exposure, not from the old unit's tonnage. A system that is too big short cycles and cools unevenly. One that is too small never keeps up on a heat wave day.
- You get options and prices. We explain the efficiency choices, whether a heat pump suits you, and what each option costs, before any work begins.
- We handle the permit and the energy code steps. Replacing equipment in San Jose generally needs a city permit, and California's Title 24 energy standards can require duct testing and sealing, airflow checks and refrigerant charge verification.
- We install and test. We set the equipment, connect the lines and electrical, start the system, check airflow and refrigerant charge, and confirm it is cooling properly.
- We walk you through it. We show you the thermostat, the filter and what to do when something seems off.
AC or heat pump?
A heat pump is an air conditioner that can also run in reverse to heat your home. In San Jose's mild climate, one heat pump can replace both your AC and your furnace.
If your furnace is also near the end of its life, it is worth pricing both together. If you have a newer furnace in good shape, a straight AC replacement may make more sense.
Federal refrigerant rules have changed what goes into new equipment. New residential systems now use lower global warming potential refrigerants such as R-454B or R-32 instead of R-410A, under the EPA's Technology Transitions rule.
Existing R-410A systems can still be serviced.

Ducts matter as much as the unit
Many San Jose homes have ducts that were designed for heating only, or that leak into the attic. A high efficiency air conditioner connected to leaky, undersized ducts will not deliver the comfort you paid for.
That is why we look at the duct system during the estimate and tell you if repairs, sealing or a return air upgrade would help. Duct testing is part of California's energy requirements when a system is replaced in many homes.
Rebates, efficiency ratings and financing
Cooling efficiency is rated in SEER2. A higher rating uses less electricity and costs more up front.
San Jose runs air conditioners fewer hours than the Central Valley, so the very top efficiency tiers take longer to pay back. We will walk through the trade off for your home.
On incentives: the big California heat pump rebate (HEEHRA) is closed to new single family reservations and the federal 25C credit ended after 2025, which our rebates and rules guide explains.

Common questions
How much does a new AC cost in San Jose?
Average installed prices in our guide are about $7,200 for a 2 ton, $9,500 for a 3 ton and $11,500 for a 4 ton. Your price depends on size, efficiency, ducts and electrical needs.
How long does an AC replacement take?
Many replacements take about a day, but it depends on the system, the ducts and the permit. We give you an expected schedule with the quote.
Do I need a permit to replace my AC in San Jose?
In most cases yes. We handle it as part of the job.
What size AC do I need?
It depends on your home's layout, insulation, windows and sun exposure, not just its square footage. We size it for your home. Square footage tables are only a rough guide.
Can I replace just the outdoor unit?
Sometimes, but the indoor and outdoor parts need to match for the system to perform and for warranty coverage. We check what makes sense for your equipment.
Should I get a heat pump instead of an AC?
In San Jose, often yes if your furnace is also old. A heat pump cools and heats from one system. If your furnace is new and working well, an AC alone may be better. We compare both.
Is there a federal tax credit for a new AC?
No. The federal 25C credit ended for equipment placed in service after December 31, 2025.
