Many overlook the importance of properly maintaining our heating systems for a comfortable home environment. We underestimate their significance until the moment they malfunction, leaving us shivering. Today, we’ll delve into a frequently asked question: How long should a furnace last?
How long do furnaces typically last?
On average, a furnace lasts about 15 years, with some performing efficiently for up to 20 years. However, several factors can influence the longevity of your furnace.
Factors Affecting Furnace Lifespan
- Brand: The brand and model of your furnace play a significant role in its durability. Established brands are known for their quality, and while budget-friendly options might save you money upfront, they may not last as long.
- Size: Proper furnace sizing is crucial. An undersized furnace will run constantly, wearing out its parts, while an oversized one short cycles, putting excessive strain on the system.
- Installation: Improper installation can lead to inefficiency, increased wear and tear, and safety risks. Always work with a licensed professional for furnace installation.
- Thermostat Settings: Setting your thermostat too high or too low can make the system work harder, shortening its lifespan. Aim for a range between 68–70 degrees Fahrenheit during the day.
- Maintenance: Regular maintenance is key to your furnace’s performance. Change the furnace filter every 90 days. Have it inspected, cleaned, and tuned up by an HVAC professional annually.
- Location: The environment in which your furnace is placed can affect its lifespan. It’s best to have it in a climate-controlled space, like a utility closet or a garage.
