Fantastic experience replacing our outdated gas furnace and water heater with a new heat pump system.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!

Licensed CA CSLB #1048009 | Same-Day Service Available
IRBIS is the HVAC Morgan Hill homeowners call for heating, air conditioning, heat pumps, and water heaters — with same-day availability and Carrier-certified status. The city sits deeper in the South Valley than San Jose, where summer heat builds and holds longer. Air conditioning is not optional here from June through September.
Summer highs in the South Valley reach 85–94°F+ — further inland than Campbell or Los Gatos, with no marine layer to cut the heat. IRBIS handles AC repair, maintenance, installation, and replacement.
Overnight lows drop to 39–45°F from November through February — colder than most South Bay cities at the same latitude. Furnace prep before the season matters.
Dry, mild winters make heat pumps a practical year-round choice here — one system for both heating and cooling. Qualifying installations may be eligible for SVCE rebates.
Repair, maintenance, and installation — traditional and heat pump water heaters — for residential homes across the South Valley.
Alert
July highs reach 85–94°F+ in an enclosed valley with no Bay breeze to cut the heat. December and January nights drop to 39–43°F — colder than Sunnyvale or Campbell at the same latitude. Both extremes demand equipment sized for the actual conditions, not Bay Area averages. Zero rainfall from July through August accelerates dust and particulate buildup in filters. Add harvest-season dust from Hecker Pass vineyards, and proper sizing becomes critical — especially in the large newer homes of Tennant Ranch, Coyote Estates, and Las Animas. SVCE rebates are available for qualifying heat pump and high-efficiency AC upgrades.
The city sits in an enclosed valley corridor south of San Jose. Summer heat builds and holds here longer than in cities with Bay access — peak temperatures run 8–10°F above coastal South Bay. Oversized or undersized systems both fail under these conditions.
The area is surrounded by working vineyards along Hecker Pass and East Main Avenue. Harvest season stirs dust and particulates that clog HVAC filters fast. Annual cleaning and MERV-rated filtration matter more here than in suburban San Jose neighborhoods.
IRBIS serves all residential property types in Morgan Hill — from older ranch homes near Downtown to large newer builds in Tennant Ranch, Coyote Estates, and Las Animas.
The primary residential housing stock runs ranch-style and two-story homes from the 1970s through the 2000s. IRBIS handles full HVAC system upgrades and replacements across all neighborhoods.
Older homes near Downtown and along Monterey Road were built without central ducts. Ductless mini-split systems deliver full heating and cooling — no renovation required.
Newer developments — Tennant Ranch, Coyote Estates, Las Animas — feature large square footage that demands precise system sizing. Undersized equipment fails fast in South Valley heat.
Heat pump, water heater, and EV charger installed as one coordinated package — built for California's 2030 gas equipment ban.

A damaged sewer line used to mean one thing: heavy equipment tearing up the yard, driveway, or landscaping to get to the pipe. Trenchless repair changed that, but it's not automatically the right fit for every situation, and homeowners looking into sewer line services are often left wondering what the method actually involves, when it doesn't apply, and how the cost compares to a traditional dig.

If you've searched "electrify my home" and come away with more questions than answers, you're not alone. Whole-home electrification is one of the biggest shifts happening in residential HVAC and plumbing right now, and it's also one of the most misunderstood.
