Service First Air Conditioning and Heating has served San Antonio since 2007, building a track record of 400 customer reviews that average 4.6 stars. The company operates under license TACLA27100C and maintains 24-hour availability across every day of the week, responding to heating and cooling emergencies throughout Bexar County, Comal County, and Guadalupe County. Homeowners in neighborhoods like Stone Oak, Alamo Heights, and Terrell Hills rely on this contractor for both routine maintenance and urgent repairs, reflecting deep roots in the local community.
What distinguishes this contractor is a commitment to transparent service that reviewers repeatedly highlight. Technicians arrive, assess the problem, and explain what repairs are needed without applying pressure to purchase additional work. The company handles indoor air quality improvements including duct sealing and IAQ equipment installations, and offers heat pump systems for homeowners seeking dual-function heating and cooling. These capabilities place Service First among a smaller group of San Antonio contractors who address both air conditioning and heating needs under one roof.
What Customers Say
Across 400 reviews, the predominant sentiment is satisfaction with honest diagnostics and fair pricing. Technicians Shane, Joseph, and Jack earn repeated mention for thoroughness and patience. Five reviewers specifically describe same-day or next-day emergency response, and none of the five-star reviews report pressure to upsell unnecessary parts or services.
