Making a major investment in a heating or cooling system is an important decision. Knowing how long your HVAC system will last is key to making the most of your purchase. Generally, these systems have a lifespan of 15 to 25 years, but this can vary depending on the type of system and other factors. Most systems last between 10 and 30 years, with an average of 20 years.
Advances in HVAC technology have made newer systems more energy-efficient than older models. If you're unsure if your system is underperforming or overworked, it's best to have a professional energy audit or inspection done by an HVAC technician. Even with a newer, more energy-efficient system, if your home isn't properly insulated or sealed, the life of the HVAC system will be shortened. It's important to be aware of the signs that it might be time to replace your HVAC system.
These include an expired warranty, irregular temperatures, and more. Many utility companies offer rebates when you upgrade to an energy-efficient model. Regular cleaning and annual professional maintenance by a local HVAC technician can help extend its lifespan.
