Radiant has helped homeowners in Austin and San Antonio keep their furnaces running safely and efficiently since 1999 with professional furnace maintenance.
We know that homes in Central Texas don’t run their furnaces like their ACs, but when cold weather arrives, it needs to work reliably. Without regular service, dust buildup and worn components can reduce efficiency or lead to unexpected breakdowns. Radiant’s licensed HVAC technicians provide professional furnace maintenance designed for homes in Austin and San Antonio, including thorough inspections, cleanings, and furnace tune-ups that keep heating systems running safely and efficiently. With the Radiant Care Club, annual HVAC maintenance is simple, affordable, and helps prevent costly repairs.

A furnace tune-up is a professional maintenance service designed to keep your heating system running safely, efficiently, and reliably. During a tune-up, a licensed technician inspects, cleans, and adjusts key components to help prevent breakdowns, lower energy costs, and extend the life of your system.
At Radiant, our furnace tune-ups include checking gas pressure, inspecting burners, cleaning or replacing filters, testing safety controls, and optimizing system performance. With over 20 years of trusted service, Radiant ensures your furnace is ready for the Texas winter — giving you peace of mind and year-round comfort.
While some basic furnace maintenance tasks can be done yourself, it’s important to know where to draw the line. Homeowners can safely:
Replace or clean air filters every 1–3 months
Keep the area around the furnace clean and clutter-free
Check thermostat settings and replace batteries if needed
Make sure vents and registers are open and unblocked
For everything beyond that — including inspecting electrical components, checking gas connections, and cleaning internal parts — it’s best to call a professional.
Radiant has been keeping Texas homes safe and efficient since 1999. Our licensed technicians provide thorough furnace tune-ups and expert care through our Radiant Care Club, so you can relax knowing your system is in the best hands.
The cost of a furnace tune-up can vary depending on your system and any additional services needed, but at Radiant, we work hard to keep it affordable and accessible for every homeowner.
For the best value, we recommend joining our Radiant Care Club, which includes seasonal furnace and AC tune-ups, priority service, and exclusive discounts — all designed to save you money and keep your home running smoothly year-round. With Radiant, you get expert care, transparent pricing, and peace of mind all winter long.
