Residential Heating & A C Inc

What Residential Heating & A C Inc does

Residential Heating & A C Inc is a privately held, woman-owned residential HVAC contractor headquartered at 65 Cristich Lane in Campbell, California, operating continuously in Santa Clara County since 1995 under the leadership of founder Cathy Wanzer-Haire (President) and Huy Phung (Vice President). The company positions itself as a Home Performance Contractor (HPC) rather than a conventional HVAC installer, using a building-science "house-as-a-system" methodology that combines blower door testing, infrared imaging, and combustion analysis to diagnose comfort, air quality, and efficiency problems before recommending solutions. Its service catalog spans the full residential HVAC lifecycle — heating and cooling installation, repair, and 22-point maintenance; whole-home energy audits; insulation, air sealing, and duct sealing; crawl space vapor barriers; indoor air quality testing and filtration; radiant heating/cooling; solar thermal; and dryer vent cleaning — and is delivered exclusively through direct field service dispatched across Silicon Valley (San Jose, Mountain View, Los Gatos, Los Altos, Fremont, Campbell).

The company's competitive offering is built on certified expertise rather than proprietary technology: technicians hold BPI Building Envelope and Building Analyst certifications, NATE certifications, ACCA membership, and Build It Green Green Point Advisor/Rater credentials, and the firm holds Mitsubishi Electric Diamond Contractor and authorized Bryant dealer status. Its revenue mechanics blend one-time installation projects (HVAC equipment replacement, home performance upgrades) with professional-services repair/maintenance work and a smaller recurring maintenance-contract stream, all quoted per-project. Go-to-market is sales-led and overwhelmingly referral-driven — 90% of business comes from word-of-mouth — augmented by a website, Yelp reviews, Angie's List (Super Service Award 2012-2014), BBB A+ rating (held since 1997), and lead flow from the Energy Upgrade California rebate program. Headcount is 1-10 employees, revenue is undisclosed, and the company has raised no outside capital, reflecting a stable owner-operated family business rather than a venture-stage growth company.
