Great job Alex
I've been a customer for years, and Reliable Air has always been a great company taking care of my system.

Paula Jensen
Alex was amazing!

Judy R
5-stars for Reliable Air & Plumbing
The guys and gals at Reliable Air & Plumbing too! all get 5-stars! From Christina, the one who answered my call to Geoff who arrived early and Trayden who met us to discuss the installation of an exposed duct HVAC in a home that I was under option period before I made the decision to buy the home. The guys helped me troubleshoot all potential barriers to completing my vision of this home. I knew after talking with them that this was not the home for me, but their helpfulness was not hinged on that. I will call them first on any home that I decide to invest in around Lockhart, San Marcos, &/or New Braunfels! Thank you all!
Emily Evans
Amazing Service from Reliable Air
Just want to take the time to give a shout out to Reliable Air and their service member Alex. Understandably they were busy, but since Alex had previously come out for regular maintenance previously, he was able to identify the issue prior to arrival. Once Alex did arrive, he checked what he assumed the issue was and fixed the problem immediately. Again, amazing service from Reliable Air and Alex.

Molly Steel
Alex has been an excellent service agent
I have been a customer since 2021, and their staff have been great. However, Alex has been an excellent service agent; knowledgeable, informative, and consistent in making sure I understand how the system works. I highly recommend this entity to trust their expertise on matters of A/C & Heating system. They get 5 stars in my book.
Denise Ramirez
Highly Recommend Reliable Air
My furnace stopped working on the coldest day of the year. Naturally, it was on a Friday evening making it impossible to find help. I left messages at several local companies to no avail. Thankfully, Reliable Air called back Saturday morning, and by that afternoon the technician (Alex) arrived. Alex went through the process of troubleshooting it while keeping me informed along the way. As a retired engineer, everything he checked made perfect sense. Alex finally came to the conclusion of what was needed and made it a priority to get it repaired as quickly as he could. After checking with others, having similar work completed, their price was right on target. I would highly recommend this company for all your HVAC needs!
Jim Huerta
Confident HVAC System
Sincerely grateful for the competent—and caring—service from Reliable Air and Alex. His visit today gave me confidence that my HVAC system is working properly and that I will be safe (and warm) this winter.
Carolyn A. Parker

Alex alerted us and arrived right on time. Alex was knowledgeable and efficient, friendly and communicative. He explained all the tests and procedures he did and left us feeling safe and confident that our HVAC system is in good working order. We signed up for the yearly maintenance contract because we feel we’re in good hands with Reliable Air and Alex!
Steve Whitehurst
Highly Recommend for New Units
Alex, their technician, is always so kind and knowledgeable. The office staff explains the plan for the day, and they review and give an estimate on-site and complete the work in a very timely fashion. I would highly recommend them for new units and maintenance/repairs.
Meredith G
Reliable Air is an outstanding company
Reliable Air is an outstanding company. Cheryl, Tom, Alex and the whole crew are the best in the business providing prompt, professional and courteous service. My HVAC went out this a.m., and I had out-of-towners on their way. Cheryl quickly responded to my “emergency,” sent Trayden to come out to assess. Trayden quickly put my fears to rest and fixed the problem immediately. I can’t recommend Reliable Air and Plumbing enough.
Linda Hummel
Detailed and Thorough Job
Alex performed the season maintenance check on our HVAC. He was detailed and did a thorough job explaining all aspects of the check-up.

Nick Stoffel
Outstanding service.
Recently had my A/C unit yearly P.M. by Trayden. Outstanding service. On-time, professional, and answered all of my questions.
Mark Andrew
Trayden was terrific
Trayden was terrific. On day 1, he came to replace our thermostat and our system, unfortunately, would not accept the thermostat he brought (because our system was installed in a way where there was not sufficient access to do so). Before I could call him back today to find out when he would be returning with the replacement thermostat that was compatible with our system, Trayden called me! That rarely ever happens with service men/women! Trayden’s follow-up was awesome! And he was one of the most knowledgeable servicemen we have had with Reliable Air. We appreciate you sending Trayden to help us out.
