Guarantee Plumbing & AC, Inc.

Guarantee Plumbing & AC, Inc. operates as a licensed plumbing contractor serving San Antonio homeowners and property managers. Founded in the early 2000s, the company maintains an office on the city's northeast side and currently holds a 3.9-star average across 41 customer reviews. Regular service hours run Monday through Friday from 8 AM to 5 PM, with Saturday and Sunday reserved for emergency callback availability. The business specializes in residential drain clearing, water heater installation, and slab-leak detection under existing concrete foundations.

Negative feedback in recent reviews raises concerns worth noting. Multiple customers describe situations where described services may not have achieved intended results, including one instance involving a cleared drainline that reportedly remained problematic afterward. Billing disputes appear across several reviews, with one customer referencing a $13,000 drain repair project and another mentioning a maintenance agreement where promised preventive checks did not prevent subsequent equipment failure. The company's receptionist consistently earns positive mention for phone handling and professional communication.
