Installing a new HVAC system is expensive. Some large homes require more than one unit, making it an even costlier venture. Extending the life of your HVAC unit is key to getting your money’s worth. Inspecting the HVAC system in your Howard County, Maryland, home for wear and tear is an important step in determining how long it’ll last.

How Long Should an HVAC Unit Last?

There are numerous factors that determine how long you HVAC system will last, including:

  • The number of hours the HVAC unit runs
  • How much preventative maintenance it receives
  • Its exposure to corrosive contaminants

Ideally, it’ll last anywhere from 10 to 30 years, with the average being 20 years.

When is a Good Time to Replace an HVAC Unit?

It’s time to replace an appliance when it has exceeded more than two-thirds of its expected lifespan. If your HVAC unit also requires more than 25 percent in repair costs than what it’s actually worth, you should also think about replacing it. With this mind, it’s best to jot down when the system was installed. That way, you can reference the date when calculating whether it’s best to repair a unit or replace it.

Tips for Extending the Lifespan of an HVAC Unit

Preventative maintenance is key to extending the lifespan of your HVAC unit. This includes changing the air filter at least once every 30 to 60 days. Many people think they only need to change the filter when running the air conditioner. However, changing the filter when the furnace is running is key to extending the system’s lifespan.

Do you have indoor pets or suffer from allergies? You’ll want to change the filter every 30 days. Pet dander can quickly clog an air filter, making it harder for the unit to achieve optimal heating and cooling efficiency. As a result, you’ll use more energy and pay higher utility costs every month.

Preventative maintenance also allows a professional HVAC contractor to diagnose and repair small issues before they become extremely costly. The contractor can perform unit upgrades to improve HVAC efficiency and enhance the comfort of your home.
