About Stay Cool Air Conditioning & Heating
Stay Cool Air Conditioning & Heating has earned its reputation as San Antonio's premier HVAC contractor through nearly two decades of reliable service. With an exceptional 4.9-star rating from 553 verified reviews, this family-centered company serves homeowners across San Antonio, Lytle, and the surrounding Texas communities. Their team of certified technicians handles every make and model, from routine maintenance to complex system installations, operating Monday through Friday from 7:30 AM to 5 PM with emergency availability.
What distinguishes Stay Cool from other area contractors is their exclusive partnership as the only Daikin Comfort Pro dealer in San Antonio. This certification unlocks 12-year parts and labor warranties on all Daikin installations, with parts shipped directly from Daikin's manufacturing facility in nearby Waller, TX. They also offer flexible financing packages starting at $89 per month and an innovative seasonal promotion: buy an AC unit and receive a free furnace. Their 24/7 Club membership provides ongoing preventive care, while the commitment to never upselling unnecessary services reflects their old-fashioned business philosophy.
Customers consistently name specific technicians who went above and beyond. Christian has earned multiple mentions for diagnosing persistent problems that other contractors missed, once even bringing portable cooling units to a home while waiting for a manufacturer part, delivering the second unit on his day off. Lionel received high praise for thorough mini-split maintenance, explaining his process professionally while cleaning both indoor and outdoor units. Kimberly's review describes how Stay Cool responded quickly when her AC failed the week before Thanksgiving, completing a full replacement with new wall and floor modifications in time for the holiday, leaving no mess behind.
What Customers Say
Among the 553 reviews, technicians Christian, Lionel, and Dion receive repeated recognition for professionalism and thorough explanations. Positive reviews consistently praise transparent communication and same-week scheduling, while the two 1-star reviews cite pricing disputes and ongoing unit problems despite maintenance plans. Notably, one reviewer describes Stay Cool bringing portable AC units during a part delay, service beyond what was originally contracted.
