Plumbing, HVAC and Electrical for Every Round Rock Neighborhood

Round Rock is the largest suburb north of Austin and one of the most varied. The neighborhoods around downtown and Brushy Creek date from the 1970s and 1980s. The 1990s and early 2000s added the big subdivisions along I-35 and toward Old Settlers Park, the ones with the round-topped attics and two systems apiece. Since then, growth has jumped east across SH 130 and north toward Georgetown, with new slab homes on open prairie.

Radiant has worked in Round Rock since the company started in 1999, and the calls follow the housing. Older homes near downtown bring galvanized water lines, cast iron drains and original gas water heaters. The 1990s subdivisions bring slab leaks, worn-out first-round replacements and attic furnaces at the end of their lives. The newest homes bring electrical panels being asked to carry EV chargers and home offices. Hard water and 100-degree summers are the constant across all of it.

Every visit is a licensed, background-checked technician, a plain-language diagnosis and a written price before any work begins. That quote is honored for 72 hours, weekend and holiday calls cost the same as a weekday, and if a repair makes more sense than a replacement, we say so. The Home Comfort Guarantee covers all of it.

  • Here since 1999 Round Rock was part of our territory from the first year, not a recent expansion.
  • All three trades Plumbing, HVAC and electrical from one licensed company, so one call covers the house.
  • Straight answers Repair or replace, you get both numbers and an honest recommendation.

What Round Rock Homes Deal With

Three generations of houses. A 1970s home near Brushy Creek, a 1996 two-story off I-35 and a 2022 build east of SH 130 fail in completely different ways. Old galvanized and cast iron in the first, slab leaks and worn first-generation equipment in the second, overloaded panels and builder shortcuts in the third. We start by asking when the house was built.

Clay to the east, rock to the west. Round Rock straddles the line between Blackland clay and the limestone that gives the city its name. Clay heaves slabs and breaks sewer joints; rock keeps slabs still but makes digging slow. A camera inspection or precise leak location tells us what we are dealing with before anyone opens the ground.

Hard water. Scale on water heaters, tankless exchangers and fixtures is the norm across Williamson County. An annual flush and a softener are the two cheapest ways to protect expensive equipment.

Hot attics and aging furnaces. Most of Round Rock’s equipment lives in an attic that passes 130 degrees in summer. That ages air handlers, ductwork and furnaces faster than a garage or closet install would.

Electrical growth. Homes wired for 1990s loads now carry EV chargers, hot tubs and offices. Our electricians assess panel capacity before adding a circuit.

Freezes. Attic water heaters, hose bibs and exposed lines on the north wall froze across Round Rock in February 2021. Insulate before the front arrives.

Round Rock and Central Williamson County

Round Rock is part of Radiant’s everyday Austin-area service territory, along with Pflugerville, Cedar Park, Hutto and Georgetown.

Frequently Asked Questions

Our Round Rock home from the 1970s still has its original cast iron drains. When do those need replacing?

When the camera says so, not on age alone. Cast iron lasts a long time, but after fifty years the inside surface gets rough and scaled, which catches grease and paper and causes repeat clogs, and eventually the bottom of the pipe rusts through. We run a camera through the line to see the actual condition. If it is rough but intact, hydro-jetting and a maintenance schedule may buy years. If it has channeled or cracked, we quote a replacement or a trenchless liner in writing. Repeated slow drains in a home that age are a reason to look, not a reason to panic.

Can Radiant handle plumbing, AC and electrical in one visit at our Round Rock house?

We can schedule all three, though they may be separate technicians because each trade is separately licensed. Many Round Rock homeowners book us for a water heater replacement and ask us to look at a tripping breaker and a weak AC on the same day, and we coordinate that through one office rather than three companies. Each technician gives you a written price for their work before starting, and the pricing does not change if the visit lands on a weekend. Care Club members get the plumbing inspection and two HVAC tune-ups each year, which is the easiest way to keep the whole house looked at. Details are on the Care Club page.

The attic furnace in our 1990s Round Rock home is original. Is it safe to keep running?

It can be, but it should be inspected every fall. A gas furnace that has spent nearly thirty summers in a 130-degree attic has a heat exchanger that has expanded and contracted thousands of times, and a cracked exchanger can let combustion gases into the air stream. Our technicians check the exchanger, the burners, the flame sensor and the venting during a furnace tune-up, and we tell you plainly what we find. If it passes, you keep running it. If it does not, we quote the repair and a replacement side by side; many Round Rock homeowners take the chance to switch to a heat pump at that point.

We just moved to a new build east of SH 130. What should we have checked in the first year?

Three things. First, the water heater and the softener loop: hard water starts scaling on day one, and a softener installed early protects every appliance downstream. Second, the AC installation: builder systems are sometimes charged or ducted in a hurry, and a proper tune-up in the first summer catches a low charge or a leaky duct while the builder warranty still applies. Third, the electrical panel: confirm there is capacity for the EV charger, hot tub or shop you are planning before you buy them. A single plumbing inspection and tune-up visit covers most of this, and everything we find comes with a written price and no obligation.

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.
