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.
Most homeowners should replace their furnace filter every 1 to 3 months, depending on the type of filter, the season, and household factors like pets, allergies, or dust levels. During heavy-use months — especially winter — it’s smart to check your filter monthly to make sure it’s not clogged or dirty.
A clean filter keeps your furnace running efficiently, improves indoor air quality, and helps prevent costly breakdowns.
If you’re unsure which filter is right for your system or how often to change it, Radiant is here to help. Our experts can recommend the best filter for your home and keep your entire heating system in top shape with our Radiant Care Club, which includes seasonal tune-ups and priority service.
Replacing a blower motor in a furnace is a detailed and technical job that’s best left to a licensed professional. It involves turning off power and gas, carefully removing the furnace panels, disconnecting wiring, unmounting the old motor, installing the correct replacement, reconnecting all components, and thoroughly testing the system for safe, efficient operation.
Because the blower motor is essential to your home’s airflow and overall heating performance, improper installation can lead to poor comfort, energy waste, or even safety risks.
At Radiant, our licensed technicians have the training and tools to diagnose blower motor issues and replace them safely and efficiently. Trusted across Texas since 1999, Radiant delivers expert repairs that protect your furnace and keep your home warm and comfortable.
