Local conditions that affect your system
Eichler radiant heat
In-slab radiant systems can develop leaks or failing boilers, and adding AC without an attic usually means ductless heads.
Title 24 permits
Most replacements need a permit and duct leakage testing verified by a HERS rater.
Heat waves and smoke
Late-summer heat and wildfire smoke make AC and MERV 13 filtration more valuable than the mild averages suggest.
Seasons and peak demand in San Jose
San Jose summers bring highs in the 80s with heat waves into the upper 90s, mostly from July through September. Winters are mild and rainy, with frosty mornings in December and January. Wildfire smoke is most likely in late summer and fall.

San Jose HVAC FAQ
How do I add AC to an Eichler home in San Jose?
Eichlers have flat roofs and no attic, so ductless mini-splits are the usual choice. The radiant floor can stay for heat, or a heat pump can take over both jobs.
Does San Jose require a permit for a new heat pump?
Yes. Equipment replacements need a city permit, and California's Title 24 usually requires duct testing on ducted systems.
