While it’s tempting to try fixing a furnace on your own, most furnace repairs should always be handled by a licensed professional. Furnaces involve complex systems, gas lines, electrical components, and safety features — and attempting DIY repairs can put your home and family at risk or even void the manufacturer’s warranty.

Trusted across Austin, San Antonio, and beyond since 1999, Radiant delivers reliable, professional furnace repair that keeps your home warm, safe, and energy-efficient — without the risks of DIY.
A typical home furnace usually lasts between 15 to 20 years, although this can vary based on the type of furnace, how well it has been maintained, and the frequency of its use. Factors like the quality of the installation and the brand can also impact its lifespan. Regular maintenance plays a crucial role in extending a furnace’s life; well-maintained furnaces are more likely to reach or even exceed their expected lifespan. Conversely, neglected furnaces may fail sooner. To maximize the lifespan of your furnace, it’s important to have it serviced annually by a professional, ensure filters are changed regularly, and address any repairs promptly. Investing in routine maintenance can significantly contribute to the efficiency and longevity of your furnace.
