An HVAC system is a significant investment homeowners make, and it only makes sense to want to get the most use out of it as possible. On average an HVAC unit can last anywhere from 10 to 20 years depending on certain factors and the climate you live in. Typically after the 10 year mark is where HVAC systems really start to show their age and develop more problems as they wear down. Most experts recommend replacing your HVAC system every 10 to 15 years.

Factors That Effect HVAC System’s Lifespan:

• Poor maintenance services – The most important factor in determining the life of an HVAC system is proper upkeep and maintenance throughout its lifetime. Many homeowners neglect getting annual maintenance done and it can drastically shorten the lifespan of an HVAC unit.
• Air filters – Regularly changing the air filter in your system is a great way of ensuring your HVAC unit isn’t overworking itself to push through dirty or clogged filters. It’s important to change your filter at least once a month.
• Location – Where you live plays a huge role in the longevity of the system. Climates that are drier tend to have dust accumulate around the coils and filters more frequently. If there is too much humidity or too little, this causes how you feel about the indoor temperature to change. Frequently adjusting the thermostat can also, overtime, lead to shorter lifespans.
• Constant Operation – HVAC units that run constantly around the clock see more wear and tear in shorter periods of time than units that don’t run constantly. The more your unit runs the more frequent filters need to be changed, and more maintenance and cleanings are required to keep up with the demand.
