Claim This BusinessExtreme Air, Inc. has served Hollister and the surrounding San Benito County region as a family-owned HVAC contractor since establishing operations locally. The company holds proper licensing for heating, ventilation, and air conditioning work in California and maintains an outstanding 4.9-star rating across 16 verified customer reviews. Their service area encompasses Hollister, San Juan Bautista, and the broader Gilroy area, with the team responding to both scheduled tune-ups and urgent calls from homeowners across these communities.

This contractor distinguishes itself through a certified partnership with Carrier, offering the Infinity Series with Greenspeed intelligence that achieves efficiency ratings up to 26 SEER for air conditioners and 24 SEER combined with 13 HSPF for heat pumps. Their offerings include Carrier's Captures & Kills air purification technology designed to filter allergens and pathogens from indoor air. The company participates in Carrier's Cool Cash rebate program, which can provide up to $2,100 in savings on qualifying system purchases. Notably, Extreme Air maintains in-house sheet metal fabrication capabilities, allowing for custom ductwork and venting solutions rather than outsourcing these components to third-party shops.
Customer reviews consistently highlight specific technicians who delivered exceptional service. Bryan Olson's review describes how team member Albert arrived to assess ductwork, provided a thorough quote, and returned to resolve a cooling issue that another contractor could not diagnose, even though it fell outside the original scope of work. Shawn is named across multiple reviews for installing complete HVAC systems including modern air conditioning and whole-house fans, with one reviewer noting Shawn completed a full heating system update for a 1970s-era home in San Jose. Raylene Nunes mentioned her whole-house fan installation works effectively to cool her home given the local coastal influences, demonstrating the team's expertise with region-specific climate solutions.
All 16 reviews carry a 5-star rating, with customers particularly noting technicians Shawn and Albert by name. Reviewers describe the company as family-owned and emphasize post-installation follow-up responsiveness when issues arise.
