IRBIS HVAC services cover the full range of San Carlos homes' needs, cooling, heating, heat pumps, and water heaters - with same-day availability and Carrier-certified status. The mid-Peninsula sun and hillside terrain both shape how these systems should be sized and installed.
San Carlos summers run warm and dry, with August highs near 73°F and zero rainfall in July. IRBIS handles AC repair, maintenance, installation, and replacement.
January lows average 45°F, and hillside homes often run a few degrees cooler than downtown. A furnace sized for the flats can underperform on higher ground.
Mild year-round temperatures make heat pumps a practical choice in San Carlo. One system handles both heating and cooling. Qualifying installations may be eligible for Peninsula Clean Energy (PCE) rebates.

Alert
San Carlos logs 264 sunny days a year, well above the U.S. average of 205. July sees zero measurable rainfall, while average highs run in the low 70s°F, and afternoons can still push past 85°F on inland-influenced days. Winters stay mild, with January lows around 45°F. Hillside neighborhoods run several degrees cooler at night than the flats near El Camino Real, which changes how systems should be sized block by block.
Most of the year brings dry, clear weather with almost no humidity buffer. Filters and coils collect dust faster under these conditions, and a system running constant dry heat needs more frequent service than one in a wetter climate.
San Carlos rarely sees extreme cold, which means a heat pump covers both seasons without the efficiency penalty it would face in a harsher climate. One system replaces both a furnace and a separate AC unit.
IRBIS services every residential property type in San Carlos, from single-family ranch homes near downtown to hillside builds and condos throughout White Oaks and Devonshire.
Most San Carlos housing is single-family, spanning from 1940s ranch homes to contemporary hillside builds. IRBIS handles full system upgrades and replacements across all neighborhoods.
Laurel Street and downtown San Carlos have a growing base of condos and townhomes with shared walls and limited mechanical space. IRBIS sizes systems built for these layouts.
Many San Carlos ranch homes built before central air was standard have no ductwork in place. Ductless mini-split systems deliver full heating and cooling with no major renovation.
Newer hillside builds in San Carlos call for precise load calculation and electrification-ready systems built for California's 2030 gas equipment ban.

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.

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.
