The Factors
Most residential HVACs will last between 15 and 25 years. Here are a few of the x-factors:- Proper size of system for home
- Installation method
- Regular maintenance
- High-quality parts
- Usage or over-usage
- Air quality in the environment
Length Of Life
Different components of your HVAC will have different life expectancies. Here are some that you may have in your home.- A typical gas furnace can last up to 30 years – possibly longer. As long as the heat exchanger works properly, routine maintenance should be enough. However, neglected furnaces can burn out in only 10-15 years if not maintained.
- Heat exchangers are also the most critical component if your home is heated by a boiler. They tend to last slightly longer, typically between 20 and 35 years.
- Your air conditioner should last between 10 and 20 years. Several components need regular checking, including the compressor and condenser. If these parts become corroded, you’ll likely need a new AC.
- Depending on usage, heat pumps can last one to two decades. Depending on your setup, heat pumps are used for both heating and cooling, so they can get a lot of use in both the summer and winter.
- If your home is ductless, you may use mini-splits to heat or cool your home. These can last up to 30 years but will quickly lose efficiency after about 15 years without proper maintenance. Thankfully, new technology means there are likely some nice upgrades whenever you decide to replace them.
