Technician was on time, very professional & friendly upon arrival. He was thorough & diligent in the conduct of his effort to diagnose the AC issue. And he was methodical & complete in preparing my bill. I called Radiant late morning Saturday & technician arrived mid-afternoon! I’m a happy Radiant customer now!

Radiant reached out to me to do a free yearly inspection of my furnace and AC. I received a visit from Eric, who was extremely knowledgeable about my AC system and taught me a bunch of stuff I didn’t know. I was impressed by the free inspection overall and thought Eric did a great job! Would definitely consider Radiant for future needs based on my interaction with them today.

Alex was very professional and completed a thorough review of my HVAC system. Although I would have preferred that the system be repaired it just needed too much work and Alex was terrific in providing me with all my options. Thank you Radiant for your overall superior service.
Radiant provides fast, reliable emergency HVAC repairs to quickly restore your comfort.
Like most people, you might not think much about your plumbing – until something happens.
Your drains are nearly invisible, but far from invincible. We’re here to help keep things flowing.
Helping improve air quality in local homes is another reason Texans trust Radiant.
On average, a well-maintained central air conditioner will last 12 to 15 years, though some high-quality systems can perform reliably for up to 20 years. Factors like the system’s quality, installation, local climate, and how regularly it’s maintained all play a role in its lifespan.
Without routine AC maintenance, components like the compressor, coils, and fan motor may wear out sooner, leading to higher energy bills and costly repairs. That’s why homeowners in Austin and San Antonio trust Radiant Plumbing & Air Conditioning to keep their systems running smoothly. With expert maintenance, timely repairs, and guidance on when to upgrade, we help you get the most life — and comfort — out of your air conditioner.
While it’s possible for a handy homeowner to attempt installing a window or portable air conditioner, installing a central air conditioning system or ductless mini-split is a job that should always be left to licensed professionals. AC installation involves electrical work, refrigerant handling, precise system sizing, and specialized tools — all of which require professional training and permits to ensure safety, efficiency, and warranty protection.
At Radiant Plumbing & Air Conditioning, our licensed technicians have been installing and replacing AC systems across Austin and San Antonio since 1999. We ensure your system is installed to code, performs efficiently, and provides long-lasting comfort — so you don’t have to risk costly mistakes or safety hazards.
Replacing your air conditioner filter is one of the simplest and most important tasks to keep your system running efficiently. Here’s how to do it:
Turn off the system — for safety, switch off the AC at the thermostat.
Locate the filter — usually inside the return air grille, at the air handler, or in a slot near the blower.
Remove the old filter — slide it out carefully to avoid spreading dust.
Check the size — the dimensions are printed on the filter frame.
Insert the new filter — make sure the arrows on the frame point in the direction of airflow (usually toward the blower).
Turn the system back on — and enjoy cleaner air and better performance!
Radiant Plumbing & Air Conditioning recommends checking your filter monthly and replacing it at least every 1–3 months— or more often if you have pets or allergies. For expert advice, regular tune-ups, or help with filter upgrades, homeowners in Austin and San Antonio have trusted Radiant since 1999.
The cost to install a new air conditioner typically ranges from $4,500 to $12,000 or more, depending on the system size, brand, efficiency rating, and the complexity of the installation. Factors like ductwork modifications, electrical upgrades, and home size can all affect the final price.
At Radiant Plumbing & Air Conditioning, we provide personalized recommendations and upfront pricing to match your home’s needs and budget. Our licensed technicians help you select the right system for maximum comfort, energy efficiency, and long-term savings. Since 1999, homeowners across Austin and San Antonio have trusted us for expert AC installations backed by transparency, quality, and exceptional service.
