Plumbing and HVAC for Cibolo, From First Repair to Full Replacement

Most of Cibolo was built in the last twenty years. That means slab foundations on blackland clay, builder-grade water heaters and air conditioners that are now reaching the age where parts start to fail, and PEX or copper plumbing that has never been touched since the walls went up. When something goes wrong in a home like that, homeowners often are not sure whether it is a warranty issue, a builder shortcut or just normal wear. We will tell you which.

Radiant has been working in the San Antonio area since 1999, and Cibolo, along with Schertz and the rest of the FM 78 corridor, is a core part of our territory. The calls we take here most often are air conditioners that quit in their first hot summer after the warranty ends, water heaters scaled up by the region’s hard water, slab leaks that appear as a warm spot on the floor, and drains that were never quite right from day one.

Our technicians are licensed, background-checked, trained and bonded. You get a clear explanation, a written price you approve first, and no surprise fees, even if the water heater fails on a Sunday. If a repair will not hold, we will say so and show you the replacement numbers, with financing available when the timing is bad.

  • Clay-soil specialists Foundation movement means slab leaks. We locate them precisely before anyone cuts concrete.
  • Builder-grade fixes We know which parts fail first in tract-built systems and carry them on the truck.
  • No pressure Repair or replace, you get honest numbers and the decision is yours.

Local Knowledge

Why Cibolo Homes Have Cibolo Problems

Blackland clay moves. The dark, heavy soil under most of Cibolo swells when it rains and shrinks hard during a dry August. That movement stresses slab foundations and the water and sewer lines running through them. Signs to watch for: a door that suddenly sticks, hairline drywall cracks, a hot spot on the floor, or a meter that spins when everything is off. Those are leak detection calls, and catching them early is far cheaper than a flooded slab.

Young systems, real wear. A home built in 2012 is not new anymore. Its air conditioner has run a dozen Texas summers, its water heater has been collecting scale the whole time, and neither was top-of-the-line when installed. Plan on the first major repairs arriving around year ten.

Hard water everywhere. Cibolo water is very hard, like the rest of the region. It shortens water heater life, clogs aerators and leaves the white crust on your shower door. A softener is the single most effective fix.

Summer load. Two-story homes with the thermostat downstairs and the bedrooms upstairs are a Cibolo classic. If the upstairs never cools, that is a duct and airflow problem we can measure, not something you have to live with.

Freeze risk. Attic water heaters and exposed hose bibs are what failed in February 2021. Insulation and a shutoff you can actually find are cheap insurance.

Frequently Asked Questions

Our Cibolo home is only ten years old. Why would it already need plumbing or HVAC work?

Ten years is a long time for equipment in Central Texas. An air conditioner here runs from April through October, often twelve hours a day, so a decade of use is closer to twenty years of service somewhere milder. Water heaters have the same problem in reverse: hard water piles scale on them from day one. Builders also tend to install the least expensive equipment that meets code. None of that means the house was built badly. It means the first round of real repairs shows up sooner than most owners expect. When it does, we will tell you plainly whether it is a fix or the start of a replacement conversation.

The doors stick and there are new cracks in the drywall. Could that be a slab leak?

It could be, and it is worth ruling out. Clay soil movement alone can cause cracks and sticking doors, but a leaking water line under the slab makes it worse by keeping the soil wet in one spot. The quick check: turn off every fixture, then look at your water meter. If it is still moving, water is going somewhere. Warm floor tiles, the sound of running water and a jump in the bill are other signs. Our leak detection equipment finds the exact spot so the repair is one opening in the floor, and you get the price before we cut anything.

Is a water softener actually worth it in Cibolo?

For most Cibolo homes, yes. Water across the San Antonio region is very hard, and the cost shows up slowly: a water heater that dies at eight years instead of fifteen, dishwashers and faucets that clog with scale, and soap that never quite rinses. A softener sized for your household stops that at the main line. We install softeners, replace worn-out units and can add reverse osmosis at the kitchen sink if you want better-tasting drinking water too. We will size it for your actual usage, not the biggest one on the shelf. Details are on our water softener page.

Can I get AC repair in Cibolo on a weekend or a holiday?

Yes. Radiant is available 24/7, including nights, weekends and holidays, and there are no surprise fees for calling on a Saturday or the Fourth of July. You will hear the price before we start, and it is the same upfront quote you would get on a Tuesday morning. If you want to skip the emergency altogether, Care Club includes two HVAC tune-ups a year, priority scheduling and no dispatch fees, which for a lot of Cibolo families is the difference between a planned visit in May and a scramble in July.

Our 18 year old HVAC system finally gave out this past week, so we reached out to Radiant to see what could be done. They sent a tech out named Bryan the same day, and he did a great job looking over the entire HVAC system. He was friendly and helpful in explaining everything that he saw, and our options moving forward. We decided to replace the entire system, so we met with Jacob (same day thankfully) to find the best HVAC system for our needs. Jacob was friendly, professional, and did a great job explaining the different options on offer. Radiant was able to set-up next day install, which was much appreciated, because the temps were still going to be cold in the coming days.

The install team consisted of Carlos and Pablo, who were very courteous and professional, and were kind enough to answer any questions I had regarding the install. They did a great job installing our new HVAC system, and were tidy which is always appreciated! Before they left, they explained everything that had been done, and showed me photos of the work.

Our entire experience from start to finish was great. I appreciate that they send photos of who is coming to your home too. Friendly, kind, professional team members, and good work all the way around. Thanks Radiant!

I had Radiant Plumbing replace my tankless water heater, damaged in the Feb. 2021 snowmageddon storm with a new unit. The process was smooth and professional from start to finish. The plumber, James, was extremely knowledgeable and thoroughly explained my options to me. The cost and time to perform the installation were just as estimated. When he was done, James explained how to maintain the system, what service would be needed and how to perform it, and answered all of my engineering geek questions. It was a thoroughly positive experience. I have used several different plumbers in Austin over the past 15 yrs, but my search is over - I will not hesitate to call Radiant next time and would recommend them unreservedly.

8/9/23 Update: I have subsequently used Radiant for a toilet repair, faucet installation (Danny), and drain work (Ezekiel) and they have continued to impress with knowledgeable, friendly plumbers and quality work.
