Shamrock Air Conditioning, LLC

Founded in 1999, Shamrock Air Conditioning, LLC is an independent firm in San Antonio, Texas. Specializing in custom duct work, installations, repair and refurbishing of old and obsolete systems, we pride ourselves in providing you with excellent, knowledgeable and friendly service.

Most of our business comes from satisfied customers’ referrals, and we work very hard to keep your business. Your comfort and safety is our number one goal. We arrive on time, we respect your privacy and your property, and we treat each and every customer as we would a member of our own family.

At Shamrock Air Conditioning, LLC, we want to earn your trust, and we show our thanks by providing you with quality, affordably-priced and 100% guaranteed work. If we repair or install your heating or air conditioning system, we will back up our work 100%. Any time there is an issue, even if it is not related with the work performed, you will not be over charged or double billed.

We understand that sometimes unexpected issues arise during a repair or installation job. We will not back out of our original estimate, and we see no reason to alter or change our prices or guarantee just because a minor (or not quite so minor) problem arises.


We treat every job as if our business depends on it, and that is exactly what each job is to us: our reputation and our business depend on your satisfaction and your safety. Without you and your recommendations we would not be in business for over 20 years.

We hope you will recommend Shamrock Air Conditioning, LLC to your friends and family, and we will treat them with the same respect and care we have shown you.
