About GG Heating & Air Inc
GG Heating & Air Inc has operated from Vallejo since 2009 under California Contractor License #1073623. The company holds an A+ accreditation from the Better Business Bureau and has amassed a flawless 5.0-star rating across five client reviews, a rare achievement in the heating and cooling trade. Owner Israel and his team serve residential and commercial customers throughout the Greater Bay Area, including San Francisco, Alameda, Contra Costa, and San Mateo Counties, bringing over 15 years of hands-on expertise to every installation and repair call.
What distinguishes GG Heating & Air from neighboring contractors is their authorized dealer status with York HVAC and their specialized focus on Samsung mini-split systems, a growing favorite among Bay Area homeowners seeking zoned cooling solutions. The company stocks equipment from fourteen major manufacturers including Carrier, Lennox, Trane, and Mitsubishi Electric, giving them flexibility to recommend systems based on each property's unique load requirements rather than pushing a single inventory line. Their maintenance program includes post-installation follow-through, and their service department handles both routine filter changes and emergency breakdowns across all makes and models they install.
Recent client feedback illustrates why the company enjoys its standing reputation. Reviewer Samara Pines highlighted owner Israel's punctuality, respectful on-site conduct, and efficient work ethic during her home installation, noting he completed the project without disrupting her household routine. Another client, Yvette Bravo, mentioned the team has returned multiple times for scheduled maintenance without any system complications since the original install. The recurring service relationships reflect what several reviewers described as reliable, explain-it-first professionalism.
What Customers Say
All five client reviews award a perfect five stars, with four reviewers specifically naming owner Israel and praising his on-time arrivals and clear explanations. No critical feedback appears in the dataset, and multiple clients mention booking the company for repeat maintenance visits.
