Alert
Sunnyvale is located in a microclimate with technology hub characteristics, making HVAC system sizing important. While July temperatures average 75°F, they may soar to more than 95°F in a heat event, and an undersized air conditioner system will not last long. On the other hand, while the temperature in January averages 49°F but may rarely drop to 35°F, a normal heat pump system performs efficiently without the need for cold-weather modifications, unlike when you move further north. In the Bay Area, dry winter seasons lead to dusty ducts and increased allergy problems; hence, more filter care
Because Sunnyvale temperatures rarely drop below 35°F, standard heat pumps operate at peak efficiency all season. The shorter heating cycle means lower operating costs compared with homes just two hours north.
Bay Area dry winters let dust and allergens accumulate faster in HVAC filters and ductwork. IRBIS recommends seasonal filter changes and can add air purification systems that keep indoor air clean through January and February.

IRBIS services all types of residences in Sunnyvale, from expansive single-family residences to old ranch houses and new builds. Whatever your heating and cooling Sunnyvale needs, we will service, repair, or replace any HVAC system for you
Our main Sunnyvale clientele are residents of single-family homes, using central air conditioning and heat pump systems year-round in their dwellings.
The demand for condos and townhouses in Sunnyvale is increasing. Zoned and mini-split systems are recommended when a common wall or HOA makes central systems installation impossible.
Quite a lot of old Sunnyvale houses don’t have a duct system in place. Mini splits address this problem entirely: there's no need to renovate your residence or tear down its walls, only fast installation.
With new constructions, IRBIS provides whole-house electrification with one visit: heat pump system, heat pump water heater, EV charging station, and more.

Residents of the City of Santa Clara, California, can get up to $10,000 back when they replace an old gas furnace with an electric heat pump. The rebate is offered by Silicon Valley Power (SVP), the city's municipal electric utility.

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.
September 28, 2026
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.
