How Long Does An HVAC System Last?

As we get into the hottest part of the year here in Hawaii, we’re reminded of the importance of our HVAC systems. Not only does the AC system help keep our homes cool, but it also helps reduce humidity and clean the air we breathe. This helps keep our homes safe and our families healthy! As you perform annual HVAC maintenance or adjust the temperature on your thermostat, you may begin to wonder, how long will my HVAC system last? When do I need to replace this system? 

How Long will My HVAC System Last?
A heating and cooling system is a big investment, and an important one. Nearly every modern home has some form of duct work, heat system and air recycling system; some even have additional parts, like an air conditioning system. Even with proper annual maintenance these machineries will eventually wear out. Most properly maintained systems are expected to last about 15 to 25 years. However, some factors will play a role in this lifespan, including maintenance level, home use and area pollution. 

Factors Of HVAC System Lifespan
You may only be able to reasonably expect your HVAC system to last 15 to 25 years, there are some things you can do to ensure that your system runs smoothly for as long as possible.
– Regular annual maintenance – this includes changing filters, having duct work cleaned and a tune-up on your HVAC system by an industry professional, such as the team at Airpro Indoor Air Solutions.
– Installing the proper sized system for your needs – if your HVAC system is too small for your needs, you may be overworking it, which will put strain on your system. When buying a home or installing a new system, make sure it is the right size for your home size, as well as family and pets.
– Proper installation – this may not be something you as a homeowner have control over, but when you choose a company to install a new HVAC system, ensure it is a licensed, trained team that is reputable in the area. Take time to read reviews and chat with friends about the best company for the job.
– Over usage – be aware of when your system is in use. Using heating or cooling functions while doors and windows are open could cause the system to work harder than it needs to, leading to overuse and early burnout.
– Poor environments – unfortunately, the Hawaiian environment can be hard on HVAC systems. Between the humidity and the corrosive salt air, our beautiful island can be difficult on our homes. This means that annual maintenance is even more important to regularly check your system and run check ups to spot potential issues early on. 

How To Know Your HVAC System Is Failing
It may seem difficult to know when it is time to replace your HVAC system or parts of the unit. After all, if something seems to be working, why mess with it, right? However, you’ll want to address a failing system and replace it before your current system completely stops working. This is Hawaii, after all, where we want our homes to be the right temperature and free of humidity and pollutants.
Here are a few signs that it is time to replace your HVAC system. 

• Age
  If your system has passed the 20-year-old mark, keep an eye on it. Many experts say you can only expect your HVAC system to last 15 to 25 years, so the older it gets, the more likely it is to wear out. 
• Repeated repairs
  It is not uncommon to have to repair your HVAC system every now and again. However, if you find yourself calling an HVAC repair technician several times per year, it may be time to replace the system. 
• Increased dust & debris
  Are you finding your home to be more dusty than usual? Your HVAC system may not be properly ventilating and cleaning the air in your home. 
• Humidity
  This is a big one for us here in Hawaii. In the same way your HVAC system removes pollutants from the air in your home, it also helps control the humidity in the building. If your home is feeling more humid lately, you HVAC system may not be working properly 
• New noises
  If you’re hearing unusual bumps, bangs, squeaks, grinding or squealing when your AC or HVAC system clicks on, it may be time to call your HVAC technician to inspect the system.
