Alert
Mountain View averages 79.7°F in July, with a record of 105°F. December lows reach 44°F, rarely dropping below 36°F. The city gets just 14.7 inches of rain per year — well below the US average of 38" — with zero rainfall in July. At 261 sunny days annually (vs. the US average of 205), systems here work harder and longer than most homeowners expect.


Mountain View is home to Google HQ, Waymo, LinkedIn, and NASA Ames. With 261 sunny days and hybrid tech schedules, HVAC systems here run longer during peak midday heat — smart, high-efficiency units are essential for home-based professionals.



Zero July rainfall and the wildfire season running from June through October mean accelerated particulate buildup and VOCs in dry air. HEPA filtration and air purifiers are practical necessities, not optional upgrades.

Monta Loma, Waverly Park, and St. Francis Acres are among the highest concentrations of Eichler homes in the US — hundreds of 1950s–60s mid-century modern builds, all designed with radiant floor heating and zero central ductwork. Forced-air AC is simply not possible without gutting walls and ceilings. Ductless mini split systems solve this completely: no structural work, no renovation, installed in one day. IRBIS technicians know these floor plans in detail — they understand how to size and position indoor units around open-plan layouts and oversized glass walls. Many homeowners have been told, "You can't add AC." IRBIS hvac service proves them wrong.
IRBIS serves every kind of property, from Eichler clusters in Monta Loma and Waverly Park to modern builds near the Googleplex and North Bayshore.
IRBIS hvac service covers air conditioning and heat pump systems for regular single-family homes — full-home comfort, even for properties near Castro Street and Cuesta Park.
More and more people are living in townhouses and condos near Shoreline West and the tech campuses. IRBIS can install systems that control the temperature in each room and mini-splits for homes that have rules about what can be installed.
Mountain View has a lot of Eichler homes. Monta Loma, Waverly Park, and St. Francis Acres have hundreds of these mid-century homes. These homes were designed with heating in the floors and no central air ducts. IRBIS thinks ductless mini split systems are the solution for Eichler homes: they do not need any big changes to the house, and they can be installed in just one day. The technicians at IRBIS know the floor plans of these homes and how to put the units in the right places around big open rooms and large windows.
Mountain View has a lot of dwelling units, which are like backyard homes or offices. Many people have converted their garages. Built separate units for offices or to rent out. IRBIS can install split systems that control the temperature in these separate units. They have their own thermostat and do not share air ducts with the main house.

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.
