Air & Drain Works is a plumber and AC repair company serving Helotes, TX, about 35 to 40 minutes from our San Antonio shop by way of Loop 1604 and Bandera Road. Unlike most cities we serve, more of our Helotes work is plumbing than heating and cooling.
What Causes Low Water Pressure In Helotes?
Water pressure comes up a lot in Helotes. A pressure reducing valve (PRV) sits where the water line enters the house and holds street pressure down to a level your pipes and fixtures can handle. When it wears out, you get one of two problems: pressure that drops to a trickle, or pressure high enough to cause banging pipes, running toilets and leaking water heater relief valves.
This year we installed new PRVs in several Helotes homes. On one call, a homeowner lost water pressure right after foundation repair. We replaced the PRV and repaired the water line, and pressure came back to normal.
When A Sink Clog Turns Into An AC Problem
Your AC pulls water out of the air and sends it down a condensate line. In many homes that line ties into a sink drain. On one Helotes call this year, a kitchen sink clog traced back to that connection, the HVAC condensate line. A plumber who doesn’t work on AC can miss it, and a backed-up condensate line can shut down the system or leak into a ceiling. We work on both, so we clear the drain and check the AC side in the same visit.
AC Repair In Helotes
Helotes grew from 1,535 people in 1990 to 9,030 in 2020, and about 80% of its homes were built after 1990. The median home dates to 2006, so a lot of systems here are in their second decade.
- AC repair: everything from small fixes to systems that stopped cooling completely, like a 10-year-old unit that quit during the heat.
- AC replacement: when a repair no longer makes sense, we price a new system sized to your home. Ask about financing, and about matching a competitor’s estimate under our Price Assurance Guarantee.
- AC maintenance and heater repair to keep the system ready for both seasons.
Leaks, Foundation Tests And Gas Lines
- Leak detection: we find the leak first so we only open what we have to.
- Plumbing tests for foundation repair: run before and after foundation work to catch damage under the slab.
- Drain cleaning: from kitchen lines to main drains.
- Gas line service: Helotes homes get gas from either CPS Energy or Grey Forest Utilities. We repair and run gas lines for water heaters, furnaces and ranges on both systems.

Helotes FAQ
A PRV lowers the city’s water pressure before it reaches your pipes. Signs of a bad one: water pressure that suddenly drops, pipes that bang when a faucet shuts off, toilets that run on their own or a water heater relief valve that drips. Most last several years, then wear out.
Yes, when the AC condensate line drains into that sink. If the drain backs up, the condensate has nowhere to go. Some systems shut off to prevent a leak. Others overflow into the attic or ceiling.
Yes. We work on residential gas lines in Helotes whether the home is served by CPS Energy or Grey Forest Utilities.
