About Shafer Services Plus
Shafer Services Plus has anchored itself in San Antonio since 1988, building a multi-generational legacy that traces its roots to a family craftsmanship tradition dating back to 1884. The company holds itself to a "Fixed Right The First Time" guarantee, backed by licensed HVAC and plumbing specialists who undergo continuous training in Central Texas. With 2,262 verified reviews yielding a 4.9-star average, this contractor has earned the trust of homeowners across San Antonio, extending service into surrounding Central Texas communities. The business operates six days weekly with flexible hours, including Sunday availability for emergencies.
What distinguishes Shafer Services Plus is its transparent approach to repair-versus-replace decisions, driven by integrity rather than profit motives. The company partners with trusted equipment brands and offers REME HALO air purifier installations, a specialized indoor air quality solution that many area contractors simply don't carry. Technicians provide same-day service with real-time text updates, and homeowners receive clear pricing before any work begins. Financing options and maintenance plans help spread costs, while a 24/7 emergency line ensures help arrives when systems fail during South Texas heat waves. The "You're Safer with Shafer" promise reflects a commitment to doing right by customers even when no one is watching.
