So how long do HVAC systems typically last? The answer depends on the system itself and the individual unit within that system. Most people would be surprised to learn just how long they can expect their HVAC system to last.
If you do not own a properly insulated property, it is vital to find out what kind of insulation your HVAC unit will need. If you live in an area where it gets cold in the winter and hot in the summer, you should consider insulating your home’s interior to prevent excess energy costs. If you are already facing energy bills, it may not be necessary for you to install additional insulation inside your home, but it can make a huge difference in how long your HVAC unit will last.
If you look at a heating unit, the answer can be as short as about three years or as long as twenty years. That is not surprising since the components are the same throughout the system. The internal components are just redesigned for each unit and then reassembled in the furnace, air conditioner, and other units that utilize that heating and cooling unit. This reassembly process tends to wear down the components and can shorten the life span of the unit.
On the other hand, if you look at the air conditioner, you will see that it is made up of several units, many of which are in separate buildings. Each unit is constructed differently, with the same necessary components. Because of this, they tend to last longer than heating and air conditioning units do. Air conditioners also tend to be less energy-efficient than heating units. This results from the fact that the units have to work harder to keep the air cool throughout the day, rather than just being able to cool off when it is cold outside.
Of course, your heating and air conditioning unit can last for a long time, even if you only use them on certain days, but it may be due to some of its internal components that are not in good shape. A significant factor affecting the life span of heating units is the air filter since that plays a significant role in the unit’s performance.
If there is a problem with the air filter inside your heating unit, you may need to replace it before it wears out completely. The replacement may be difficult, though, since you need to locate the filter and remove it to get to the component. Besides, this is a relatively complex process. You will need to disassemble the entire unit to find the filter, reinstall it in the appropriate spot where the filter is located, and adequately reinstall the component.
With an air conditioner, this is not necessary. When the air conditioner comes from the air filter, you need to make sure you replace the filter, replace the unit, and immediately restore the cooling efficiency and performance to the unit. It will then require very little maintenance after that. In some cases, the filter can be replaced several times per year, while others only need to be replaced once every six months. Either way, the best answer to your question of “How long do HVAC systems last?” is to replace the filter of your air conditioner whenever it starts to show signs of wear and tear.
