Fix my ACStraight Answers for Cibolo’s Newer Homes
Cibolo grew fast, and a lot of its homes are young enough that the first real plumbing or AC problem is a surprise. Radiant fixes it right, with the price approved before we start.
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.

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.
Cibolo, Schertz, Universal City and Converse are all in our everyday San Antonio service area.

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.
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.
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.
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.
