When your AC quits on a hot San Marcos afternoon, or a pipe lets go under the sink, you should not lose a whole day waiting on a technician. Reliable Air books same-day and shows up inside a two-hour window, with the same familiar faces we have sent out since 1996. Air conditioning, heating, and plumbing, all under one roof.
One local team for air conditioning, heating, and plumbing, serving Central Texas in English and Spanish. Financing available, with free estimates.
Cutting corners means do it cheaper, do it faster, just get it done. When an HVAC company works that way, you pay the price later. Since 1996 we have done it the other way, built on three simple things.
By far the best company you can find. No pressure, no salesy pitch. They kept helping us even when they knew our system was old, and worked around our schedule.
Air conditioning, heating, plumbing, and air quality from one trusted local team. No juggling three different contractors when something goes wrong.


Residential and commercial. Financing available and free estimates. Ask when you call.
The Texas heat does not wait, so getting your home comfortable again should not come with a week long wait or a mystery bill.
Call (512) 580-8837 or book online. Most repairs are same-day, and we give you a two-hour arrival window so you are not waiting around all afternoon.
A trained technician arrives on time, finds the real problem, and explains it in plain terms, with the price up front, before any work starts.
Whether it is AC, heating, or plumbing, our people are trained to do it right the first time. And if we ever get it wrong, we make it right.

"This is Cheryl, the owner of Reliable Air. When I started Reliable Air in 1996, I aimed to do things a little differently." For Cheryl that has always come back to faith and family: hiring for character as much as skill, and investing in people so they stay for the long run. The nice side effect is that you hear a familiar voice on the phone and see a familiar face at your door, year after year.
Based in San Marcos and covering the New Braunfels, Seguin, Kyle, and San Antonio corridor across Hays County and beyond.
If we say we will be at your home at a certain time, we will. And if we ever get it wrong, we make it right.
Most repairs are same-day, with a tight arrival window so you are not stuck waiting around.
Five percent off any repair for seniors, military, and first responders.

A local team that has picked up since 1996 and will not sell you what you do not need.
