About Guarantee Plumbing & AC, Inc.

Guarantee Plumbing & AC, Inc. is a family-owned business located in Olmos Park. We have employed HVAC specialists and plumbers in San Antonio since 1934. Few plumbing companies in the United States can match our record of success and dedication to customer satisfaction.

Licensed, Bonded, & Insured

Our employees have the knowledge, experience and dedication to professional excellence you expect from a licensed specialist. A licensed master plumber in Texas must have 8+ years of experience, with at least 4 years as a licensed journeyman. Each of these steps requires a thorough examination process to ensure that the individual has working knowledge of the profession. In addition, each plumber is required to complete continuing education courses each year to maintain their status as a licensed professional.

Offering Green Products & Why It Matters

Many new homes are built with energy-saving systems already in place, from roofing shingles to air conditioning and water heating. Many older homes are remodeled to install these measures. There are two major benefits to going green in the home: saving unnecessary expenses on utility bills and making a positive impact on the local environment.

We have offered green, energy-saving installations and replacements since 2005. As new plumbing, heating, and AC systems become more cost-effective and energy-efficient, we may continue to offer these alternatives to Texas residents who seek to update the comfort of their home and improve the quality of their lives according to their changing needs.

Our 100% Guarantee on Labor & Parts

After we make a repair, we offer a 100% guarantee on the parts and labor for one year—if the covered part fails within the warranty, we replace it at no additional charge. We make this guarantee for two reasons: we are confident in our ability to deliver effective solutions, and more importantly, we put the comfort and satisfaction of our customers first.

Serving Commercial & Business Customers

Many companies offering plumbing and HVAC service in San Antonio may not be available to both residential and commercial customers. At Guarantee Plumbing & AC, Inc., we have the skills and experience to handle our customers’ needs in the home or at the office. Commercial and business establishments of all kinds rely on us for effective solutions.
