How Long Does HVAC Usually Last?

Regular maintenance can extend the lifespan of HVAC systems, but you will eventually need to replace the unit as it is not designed to last forever. There are several factors that can cause these units to become inefficient or break down beyond repair. This includes environmental factors and the type of HVAC unit. Typically HVAC systems last around ten years, but this can vary. Continue reading to learn more about the lifespan of HVAC systems.

Lack of Maintenance 

One thing that can drastically reduce the lifespan of an HVAC unit is the lack of maintenance. Without maintenance, the components of the HVAC unit can experience excessive wear and tear. This can cause the entire system to fail. Preventive care includes cleaning and servicing the AC unit on the manufacturer's recommended schedule. If you are uncertain about this recommendation, seek guidance from an experienced HVAC technician. Technicians can also thoroughly inspect the system to find and fix any issues with the HVAC. 

Environment and Location 

The environment is another significant factor in the lifespan of the HVAC unit. Airborne particles can be released from household products into the indoor environment, which can impact the lifespan of the AC unit and cause other HVAC issues. 

The average ambient temperature and the climate of your location also play a vital role in the lifespan of the HVAC unit. For example, HVAC units installed in colder climates can have more wear and tear on their heating system than cooling systems. Similarly, HVAC systems installed in coastal areas can be more susceptible to corrosion, making the system more prone to leakage. 

Usage 

High usage of the HVAC system can also reduce its lifespan. However, regular preventive maintenance and smart thermostats can help reduce the stress on the unit. Extended use of the system can also harm its efficiency as the components can suffer from excessive wear and tear and accumulation of airborne contaminants.  

Size of the System 

The size of the house compared to the HVAC unit's output ability is another critical factor that affects its lifespan. If you have installed an HVAC system that is too small for the room, it may have to work harder to achieve the desired temperature. 

If you have installed a unit that is too large for the space of your home, that could also impact its lifespan. With a larger unit, the HVAC might have short cycles, where it turns on and off too frequently. This can result in reduced life of the HVAC and poor energy efficiency. 

Ideally, you want to use an appropriate HVAC unit for the size of the room or house. You want to get expert advice from an HVAC technician to get the right size. 

Installation Procedures

HVAC systems tend to vibrate during operation, and if they are not appropriately secured during the installation process, the vibration can increase, which causes components of the HVAC system to become loose. Too much vibration can also cause the electrical components to short circuit.
