Fantastic experience replacing our outdated gas furnace and water heater with a new heat pump system. The team was professional and efficient. The best part? We saved thousands thanks to the generous rebates available. This upgrade is definitely worth it.

Cannot be happier with my new Heat pump water heater. It's been 2 weeks since I have it and it's working great! Tim did a thorough evaluation and installers performed neat work. Evan called to make sure we are all set up! Definitely use them again!

IRBIS provides full heating and air conditioning services across San Mateo — cooling, heating, heat pumps, and water heaters — with same-day availability and Carrier-certified status. The Peninsula fog keeps mornings cool, but inland heat events push temperatures to 90–95°F+, and the coast does not fully protect. Having a reliable system matters more than residents expect.
July averages 72–76°F, but inland heat waves push San Mateo to 90–95°F+, and the marine layer offers no guarantee. IRBIS handles AC repair, maintenance, installation, and replacement.

Alert
July highs average 72–76°F, but heat waves push inland areas to 90–95°F+ — the coast does not fully protect. January lows hit 42°F, with coastal fog dropping the felt temperature to around 35°F. San Mateo sits within the California Fog Belt, with 100+ fog days per year and summer humidity ranging from 65–80% in Bayside neighborhoods. Systems here face conditions that differ significantly from those in the inland South Bay. Annual rainfall reaches ~24 inches — well above Sunnyvale (16") and Santa Clara (15") — and salt air near Foster City, Coyote Point, and Mariner's Island accelerates corrosion on outdoor HVAC units. San Mateo is served by Peninsula Clean Energy (PCE), the local community choice energy aggregator, which offers rebates for heat pump and high-efficiency AC upgrades.

Alert
San Mateo sits in one of the Bay Area's foggiest corridors. Humidity stays elevated through summer, condensation builds inside units year-round, and equipment that works fine in drier climates wears faster here. Maintenance intervals matter more than most homeowners realize.
Homes near Foster City, Coyote Point, and Mariner's Island are exposed to salt-laden air that corrodes condenser coils and electrical contacts faster than standard Bay Area conditions. Coil coatings and annual inspections extend unit life by years in these neighborhoods.
IRBIS delivers HVAC services to every residential property type in San Mateo — from single-family homes in Aragon and Beresford to condos near Hillsdale and pre-1960 properties across Baywood and San Mateo Park.
San Mateo's single-family housing spans mid-century ranches and two-story builds from the 1950s through the 1990s. IRBIS handles full HVAC system upgrades and replacements across all neighborhoods.
Hillsdale, Bay Meadows, and Downtown San Mateo have a growing base of attached homes with shared walls and limited mechanical access. IRBIS sizes and installs systems built for these layouts.
Older homes in Baywood, San Mateo Park, and College Heights were built without central ducts. Ductless mini-split systems deliver full heating and cooling — no major renovation required.
Heat pump, water heater, and EV charger installed as one coordinated package — built for California's 2030 gas equipment ban and eligible for PCE rebates.

July 15, 2026
Most plumbing problems don’t announce themselves in advance. A water heater that’s quietly filling with sediment, a supply line under the sink that’s slowly degrading, a drain that’s 80 percent blocked but still technically draining — these issues build up over months and years until the day they turn into an emergency call and a water-damaged floor.
July 8, 2026
Air conditioner replacement cost in San Jose almost never lines up with the national figures online. Most national estimates land between $5,000 and $12,000.
July 6, 2026
Most homeowners don’t think about their pipes until something forces the issue — a persistent drop in water pressure, water that runs orange when you first turn on the tap, or leaks that keep appearing in different spots, no matter how many times they’ve been patched.

Choosing the right heating and cooling system for your home is more important than you might think. It affects your comfort, energy bills, and even the environment.
