The Life Expectancy of My HVAC Equipment

Every homeowner wants to know how long they can expect their HVAC system to last. The answer to this question is dependent on a few different variables, but industry average for HVAC equipment is 15 years.

Lets talk variables now. The life of your system depends on how the capacity of the system was determined, how the system was designed and installed, how the system is maintained, the climate and environment that you live in and the quality of the equipment itself. You, the homeowner, have some control over the longevity of your system, meaning how soon you will need to replace it depends partly on you.

When it comes to your HVAC unit, size matters. When the system was put in, someone designed it especially for your home. If it wasn’t done properly and ends up either too big or too small it will not run properly causing your equipment to wear out prematurely.

When a system is originally installed, the design and lay out of the ductwork is very important. There must be a balance of airflow coming in and out of the system.
The placement of the ductwork also needs to be considered. Think about your ductwork like a straw. You want to be able to pass air easily through a straw. If you have to force air through it or cannot get air through while sucking on a straw something is wrong. The same goes for your ductwork.

Every piece of machinery needs to be taken care of. We all know if you don’t take care of your car- change the oil, get regular tune ups, rotate the tires etc., then your car will start breaking down. If you continue to use it without fixing it, you shorten the life of your vehicle. The same is true for your HVAC equipment. You must change your filter regularly and get regular inspections/tune ups to keep it clean and in working order.

Environment and climate are another factor that can affect the life of your HVAC system. For example, an air conditioning unit is going to get a lot more use in Arizona than it is in Maine or even Indiana, just as a heating unit will get more use in Maine and Indiana than it will in Arizona. Also, if you live seaside, that salty air that you love can wreak havoc on your HVAC unit, just as it does on everything else.

Homeowners also need to make sure that debris doesn’t get caught in the outdoor unit. Cottonwood tends to be one of the biggest culprits here in Indiana. Those fluffy bits that fly around get caught in your coils, reducing the amount of airflow therefore making your unit less efficient and costing you money. We also have to watch out for hail damage. Hail can bend the fins that cover the coil. When they get bent, they can damage the coil.

Here in Indiana, our four seasons are considered to be pretty normal. All it takes is an extremely cold winter or extremely hot summer to have your equipment work over time just trying to keep up. These are times that you would especially hate for your system to fail, so keep it maintained to reduce this risk.

So, the overall rule to go by is that most HVAC equipment will last an average of 15 years. There are variables that can affect the life of your equipment; one of them being how well the homeowner maintains the equipment.
