    They were able to diagnose the root cause and fix an issue that had been a nagging problem ever since the HVAC was installed by another company. 3 years of frustration cured in under an hour!

    I am very happy with the professional informative technicians and office people at Reliable Air. I HIGHLY recommend this San Marcos company who now does plumbing. Today they installed my new water softener and I am very happy with their service. Thank You Geoff and Cheryl!!

    As a contractor myself, I’ve worked with Reliable on several projects in the past. Knowing their quality of work, when I needed work on my own home I knew who to call. Arrived on schedule. Diagnosed to problem and fixed it quickly. Travis was friendly and helpful and answered my questions. I would recommend them to anyone.

    When I called to request service they were able to send someone out that same day. When Edgar arrived he was polite and courteous. He explained what he was going to complete the diagnostics first. He then explained what needed to be done and made sure I understood. It was very appreciated that he gave me time to decide on my repair because it was going to cost a bit of money. He finished quickly and explained the invoice. Great job!

    Joseph was very knowledgeable and quick to respond. He knew exactly what needed to be fixed and he was right on it. I thank you all for the quick, fast and in a hurry respond you did for my family and I. Especially during this freezing weather. Thank you Joseph for being so kind and understanding. I will use you guys again in the near future!
