Alert
Average temperatures in July are around 77 degrees F in Milpitas, although the easternmost neighbourhoods near Ed Levin Park & Calaveras can reach the 90s- 95 degrees or above. This is because the hills block out the Bay Breeze, which cools the western parts of the city in the I-880 corridor. The average temperature during the month of January is 48 degrees with a minimum of 38 degrees. Systems must be designed to provide the cooling and heating demands year-round. The concentration of high-tech workers living in Milpitas increases the demand for smart thermostats, premium systems, and energy efficiency. Silicon Valley Clean Energy (SVCE) supplies electricity and provides rebates for qualifying heat pump and AC upgrades.
Eastern Milpitas neighborhoods near Ed Levin Park and the Calaveras area get less Bay Breeze — temperatures run 5–8°F higher than western Milpitas near I-880. System sizing must reflect this difference.
Bay Area dry summers cause dust and particulate buildup in HVAC systems faster than in humid regions. Annual filter replacement and coil cleaning are recommended for Milpitas homes — especially near the I-680/880 corridor.
SVCE (Silicon Valley Clean Energy): Rebates for qualifying heat pump and AC upgrades.
California Energy-Smart Homes: Up to $4,250 on qualifying systems.
Tech Clean CA: Equipment credits for eligible installations.

Search for a cold weather plumbing checklist, and you will get the same list every time: insulate your pipes, disconnect the garden hose, let the faucets drip overnight. It is good advice, and it is written for Chicago.

Your furnace has been sitting idle since spring. On some October evening, the Bay Area drops into the 40s, you push the thermostat up for the first time in months, and the system pulls air through whatever furnace filter was left in the slot back in May. That first heat cycle is when a neglected filter does the most damage: months of collected dust, pollen, pet hair, and summer wildfire smoke particles sitting directly in front of your blower.
