Plumbing, Cooling and Heating for Every Era of Converse Home

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.

  • Old and new alike Original 1970s plumbing or a 2020 build, we know the failure points of both.
  • Close to home Converse is minutes from our San Antonio office, so scheduling is straightforward.
  • Written, honored quotes Good for 72 hours, no hidden fees, useful when you are timing a move or a sale.

Local Knowledge

What We See in Converse Homes

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.

Frequently Asked Questions

My Converse home is from the 1980s. What plumbing and HVAC problems should I expect?

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.

Why does my water bill keep climbing when nothing looks wet?

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.

We just moved to Converse for an assignment at Randolph. How do we get a baseline on the house?

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.

Can you replace the furnace and the AC at the same time, and is there financing?

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.

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.
