Repair my ACReliable Repairs for Northeast San Antonio Homes
Converse has 1970s ranch homes and brand-new subdivisions on the same street. Radiant knows what fails in each, and we tell you the price before the work starts.
Converse sits on the northeast edge of San Antonio in Bexar County, close to Joint Base San Antonio-Randolph, and the housing reflects that. There are established neighborhoods of single-story homes from the 1970s and 80s with original ductwork and aging water lines, and there are newer subdivisions off Loop 1604 and FM 78 where the equipment is younger but the clay soil is the same. A lot of the families we meet here are military, which means they are moving in, moving out or renting, and they need honest answers fast.
Radiant has served San Antonio since 1999 and Converse is a short drive from our office. The most common calls from here are air conditioners that cannot keep a single-story home cool through August, cast iron or galvanized lines in older homes that are finally corroding through, water heaters in the garage that have quietly rusted for a decade, and sewer lines that clay-soil movement has cracked or offset.
Every technician is licensed, background-checked and bonded. You get a plain explanation, a price before any work, and our Home Comfort Guarantee behind it. If a repair is throwing good money after bad, we will tell you and lay out the alternatives, including financing if a replacement lands at a bad time.

Two generations of housing. The older Converse neighborhoods were built when galvanized steel supply lines and cast iron drains were standard. Fifty years later, the galvanized pipe is rusting shut from the inside, which shows up as brown water after a vacation and pressure that gets worse every year. Cast iron drains develop rough scale that catches everything. A repipe or a sewer line replacement is a big decision, so we camera and pressure-test first and show you what we found.
Clay under everything. The soil on the northeast side swells and shrinks with the weather. Sewer lines crack or separate at the joints, and slab plumbing can leak where the foundation flexes. If drains are slow throughout the house rather than at one fixture, the problem is probably in the yard, not the sink.
Single-story heat load. Many Converse homes are one story with the ductwork in a low attic that hits 140 degrees in summer. Leaky or crushed ducts waste a large share of the cooling you pay for. Duct sealing and a right-sized system usually beat simply installing a bigger unit.
Freeze exposure. Garage water heaters, hose bibs and pipes in exterior walls were the casualties in February 2021. We insulate and add accessible shutoffs so the next freeze is boring.
Converse, Universal City, Schertz, Cibolo and the surrounding Bexar County neighborhoods are part of our daily routes.
Save on the work your home needs most.
Three things, mostly. First, the supply plumbing: if it is galvanized steel, it is nearing the end of its life and will show up as low pressure and rusty water. Second, the drains: cast iron lines scale up inside and clay soil shifts the sewer line in the yard, so slow drains and recurring clogs are common. Third, the HVAC: the original ductwork is likely leaking in the attic even if the equipment has been replaced. None of these require panic. A plumbing inspection and an HVAC tune-up will tell you where the house actually stands, and we will rank what matters versus what can wait.
The leak is usually somewhere you cannot see: under the slab, in the yard between the meter and the house, or in a toilet flapper that lets water trickle through all day. Toilets are the cheap culprit, so start there by adding food coloring to the tank and checking the bowl after twenty minutes. If the toilets are fine and the meter still turns with everything off, it is time for leak detection. We use acoustic and pressure equipment to find the spot without tearing anything open, then quote the repair before we start.
Book a whole-home look before the first emergency. Our plumbing safety inspection checks the water heater, supply lines, shutoffs, drains and pressure, and an HVAC tune-up checks the cooling system before summer. You get a written rundown of what is fine, what needs attention soon and what can wait, with no pressure to do any of it that day. If you would rather have it handled on a schedule, Care Club is $9.99 a month and includes both annual tune-ups and the plumbing inspection, plus priority service and no dispatch fees.
Yes to both. If the outdoor condenser and the indoor furnace or air handler are the same age, replacing them together usually makes sense: the new components are matched, the efficiency is what the label says, and you avoid paying for a second install visit in a few years. We will price it both ways so you can compare. Financing is available through Service Finance Company with no interest and no payments for six months, subject to credit approval, and any HVAC install over $3,000 is quality-reviewed by a manager under our Home Comfort Guarantee.
