Air1st Heating & Cooling, LLC

Air1st Heating & Cooling has operated as a family-owned San Antonio business since 2007, delivering two full decades of residential and commercial climate control across the Texas Hill Country and Greater San Antonio region. With a near-perfect 4.9-star average across 174 client reviews, the company maintains standard business hours Monday through Friday from 8 AM to 5 PM, with Saturday service available until 4 PM. Their documented service territory spans at least 13 communities, including Boerne, New Braunfels, Seguin, and San Marcos, making them a regional fixture for homeowners seeking licensed HVAC support beyond the city core.

What distinguishes Air1st is their combination of a 10-year workmanship warranty backed by same-day service availability and flexible financing options that accommodate tighter household budgets. The company offers 24/7 emergency support for furnace, heat pump, and air conditioning failures, a practical feature for South Texas summers when system failures create immediate health concerns. Their bilingual team serves Spanish-speaking clients directly, and military and senior discounts provide additional pathways to affordable climate control.

Reviewers repeatedly name specific technicians who delivered exceptional service: Joseph Mancillas earned recognition as a highly knowledgeable problem-solver over 73 years of homeowner experience, while Nelson and Austin performed a temporary fix on an older unit to prevent a family's discomfort through a weekend when parts were unavailable. Several clients note same-day arrival during heat-wave conditions, with Jesus responding to a late-evening call by arriving the following morning for an urgent repair.
