Zero Heating AC & Refrigeration

Zero Heating AC & Refrigeration operates as a residential-focused HVAC contractor headquartered at 114 Park Plaza in San Antonio, Texas. Backed by a team accumulating more than three decades of field experience, the company maintains a perfect 5.0-star rating derived from 539 client reviews. Their service footprint extends across Bexar County, with dedicated coverage for communities including Alamo Heights, Stone Oak, Helotes, Boerne, and New Braunfels. As a 100% residential specialist, they handle air conditioning repair, heater maintenance, and complete system replacements for homeowners throughout the San Antonio metro area.

Unlike contractors who juggle commercial and residential portfolios, Zero Heating concentrates exclusively on home climate systems. The company offers an annual Maintenance Agreement program designed to preserve system efficiency and extend equipment lifespan. Their technicians deliver upfront, transparent pricing before any work begins, eliminating the surprise invoice scenario that frustrates many homeowners. This specialization allows their team to develop deeper expertise in residential equipment diagnostics and installation techniques specific to Texas housing stock.

Customer reviews name specific technicians who arrived when urgency demanded. During a February cold snap that caused a failed disconnect panel, Michael and Anthony installed an entirely new system so Gloria and her son could sleep warm after a freezing night. Jose Ruiz completed a same-day replacement for Anthony Ortiz, whose newly purchased home hidden defects other contractors had quoted at $17,000. Nathan and his crew finished an AC installation faster than the original quote, then walkthroughed the system operation and maintenance schedule with the homeowner.
