Air conditioners are crucial pieces of equipment and a huge investment, so you want to make sure that you fully utilize them. Luckily, most units are effective for 15–20 years, but it depends on several aspects. Since you want yours to serve you longer, below are four factors affecting how long an air conditioner unit should last.
1. Usage Rate
As you know, the more you overwork equipment, the more it wears out. This is the same case with an AC unit because if you use it frequently, making it run more than average, it will quickly be near its end of life. If you live in a warmer climate and need it running longer or you have a lower thermostat setting, it will affect how long your air conditioner lasts.
2. Level of Maintenance
Your unit also needs some TLC to serve you longer, like other systems around your home. If you want to extend its service life, it helps to call in experts to conduct regular maintenance. Thanks to such tune-ups, the HVAC professionals can identify any issues or risks with the system, replace the filters, or perform any service that will get the AC back in great shape to serve you better.
3. Exposure To Elements
The AC unit stays outside throughout the year, exposed to various elements. Therefore, your climate, surroundings, air quality, and weather conditions can easily affect it. For instance, living in a coastal region takes a toll on the AC, considering the salty and humid air. The equipment is designed to withstand the elements, but extreme exposure for a long time can affect its efficiency and reduce its lifespan. You should try to keep the surroundings clean and manually remove any debris that would cause blockage.
4. Installation Quality
How a piece of equipment is installed determines how it runs and how long it lasts. For your AC to last longer, you need expert HVAC installers using high-quality equipment. Some users perform DIY repairs and maintenance on their systems, which can be risky and damage the system. The quality of installation determines how long an AC unit should last, so consider hiring professionals for replacements and repairs.
