AC & Heating Installation in San Jose

AC & Heating Installation in San Jose

San Jose has the widest housing mix in the region, and installation here splits into two conversations. Summers run 85 to 95 with stretches over 100, so for most homes the cooling load drives the equipment sizing. Heating is mild, with a winter design temperature in the mid-30s, which is comfortably inside any modern heat pump's range. That combination is why heat pump conversion has become our highest-volume install in newer San Jose stock.

Then there are the Eichlers. The mid-century Eichler homes across Willow Glen, Cambrian, and Fairglen were built with radiant-slab heat and no ductwork at all. The radiant systems are copper buried in concrete, so when they fail there is no practical way to fix them, and most failed years ago. For these homes the answer is almost always a ductless mini-split. Wall-mounted heads keep the open ceilings the architecture is known for intact, and the condensers sit out of view in the side yard. We have done a number of these retrofits, and for an Eichler ductless is the standard call.

For 1990s and later homes with intact ductwork, the install conversation is increasingly about replacing an aging gas furnace and AC with a heat pump at end of life rather than putting in another gas system. BAAQMD Rule 9-4 will restrict gas furnace replacement starting 2029, so we factor that into the decision. We run the Manual J load calculation, inspect the ducts, and put the equipment, ductwork, and electrical scope on the written estimate before any sale conversation.

What we run into in San Jose

Eichler ductless retrofit. Dead radiant slab, no ducts, open-ceiling architecture. We install wall-mounted ductless heads and tuck the condenser into the side yard, so the house stays cooled and heated without cutting into the original ceilings or running new ductwork.

Heat pump conversion on newer stock. On 1990s and later homes with good ducts, we replace end-of-life furnace-and-AC pairs with a single heat pump. We recommend lines that hold full capacity through San Jose's mild winter lows, so the house stays warm on the coldest mornings.

Full system replacement on 20-plus-year equipment. Older homes carry a long tail of Trane, Lennox, and York systems past two decades. We size the replacement to the actual cooling load, not the old tonnage, since a lot of these were spec'd by rule of thumb and run oversized.

Duct inspection and sealing with the install. Cooling-driven climate means leaky ducts cost you on the hottest days. We test ducts on every install estimate and seal or retrofit where leakage is high, so the new system's capacity reaches the rooms instead of the attic.
