Radiant Plumbing & Air Conditioning

When a pipe bursts in the middle of the night or your toilet won't stop running, you need a plumber you can count on immediately. Our 24/7 emergency plumbing service in San Antonio is designed for these exact moments. We dispatch licensed, experienced technicians who arrive prepared to handle burst pipes, frozen lines, major leaks, and sudden loss of water pressure with speed and precision.

This service is for any homeowner or property manager facing a plumbing crisis that threatens property damage or makes your home uninhabitable. The process begins with your call, where we listen to the symptoms and get a technician headed your way. Upon arrival, our expert performs a thorough inspection to pinpoint the source of the problem. You'll receive a clear, upfront quote before any work begins. Using professional-grade tools and techniques, we execute a permanent repair, not just a temporary patch, and clean up our work area completely.

Choosing Radiant means choosing a team that values your safety and peace of mind above all. We don't believe in upselling during an emergency; we believe in honest diagnostics and transparent pricing. Our work is backed by the Home Comfort Guarantee, ensuring the repair holds. With weekend and holiday availability and a fleet of fully stocked trucks, we are the reliable, no-guesswork solution San Antonio trusts when the unexpected happens.

The intense heat of a San Antonio summer makes a fully functional air conditioning system not a luxury, but a necessity. Our comprehensive AC repair and maintenance services ensure your home stays cool, comfortable, and energy-efficient all season long. From strange noises and weak airflow to complete system failures, our licensed HVAC technicians are equipped to diagnose and resolve any issue with your central air, ductless mini-split, or heat pump system.

This service is essential for homeowners experiencing discomfort, rising energy bills, or concerning sounds from their AC unit. For maintenance, we recommend biannual tune-ups to prevent costly breakdowns. The service process involves a detailed system evaluation: we check refrigerant levels, inspect electrical components, clean coils, calibrate your thermostat, and ensure all moving parts are lubricated and functioning. For repairs, we provide a clear explanation of the fault, offer repair versus replacement options based on the system's age and condition, and proceed only with your approval.

Radiant stands out as your San Antonio HVAC expert because we focus on long-term performance, not quick fixes. Our technicians are factory-trained and adhere to strict quality standards. We use top-tier parts and provide honest advice on whether a repair is in your best interest. Backed by our guarantee and offering flexible scheduling, including our popular $79 AC tune-up, we deliver the reliability and expertise your home's comfort demands.

Slow drains, recurring clogs, and sewer backups are more than just inconveniences; they are signs of a deeper problem within your home's drainage system. Our professional drain and sewer line services in San Antonio use advanced technology to not only clear the immediate blockage but to diagnose and address the root cause, preventing future issues and protecting your property's foundation and plumbing.

Homeowners noticing gurgling sounds, multiple slow drains, or water backing up in tubs and sinks need this service. We start with a state-of-the-art sewer camera inspection, snaking a high-resolution camera through your lines to visually identify the problem—be it grease buildup, tree root intrusion, a collapsed pipe, or a misaligned joint. Based on the findings, we recommend the best solution, which may include high-pressure hydro jetting to scour pipes clean, traditional snaking, or more extensive main line repairs or replacements.

Why trust Radiant with your San Antonio home's hidden infrastructure? We invest in the best equipment, like industrial-grade hydro jetters and locator cameras, to ensure accurate diagnostics and effective solutions. Our "$83 Drain Clearing or It's Free" offer demonstrates our confidence. We provide honest assessments, explaining if a simple clearing will suffice or if a larger repair is needed. With licensed specialists who respect your home and a commitment to permanent fixes, we restore proper flow and give you one less thing to worry about.

Reliable hot water is central to daily life, from morning showers to washing dishes. When your water heater fails, leaks, or can't keep up with demand, Radiant provides expert repair and installation services for both traditional tank and modern tankless systems throughout San Antonio. We ensure you have an efficient, safe, and dependable supply of hot water for your household.

This service is for homeowners experiencing no hot water, inconsistent temperature, rusty water, leaks around the tank, or unusually high energy bills. Our process begins with a safety and performance inspection. For repairs, we diagnose issues with heating elements, thermostats, valves, or tanks. For replacements, we help you choose the right unit—considering fuel type, capacity, energy efficiency (like ENERGY STAR® models), and space—and handle the entire installation, including proper disposal of the old unit, code-compliant plumbing and venting, and thorough testing.

Choosing Radiant means partnering with specialists who prioritize your safety and long-term value. We are licensed for both plumbing and gas line work, a critical combination for water heater services. Our upfront pricing includes all parts and labor, with no hidden fees. We offer maintenance plans, like our $99 Water Heater Flush, to extend your system's life. Backed by our guarantee and offering specials like "Up To $250 Off A New Tank Water Heater," we deliver the expertise and peace of mind you deserve for this essential home appliance.
