Hallmark HVAC age & equipment life expectancy
Many homeowners want a Home Inspector to predict how long their HVAC equipment will last. This is simply impossible and beyond the scope of a Home Inspection — depending on the model, installation, maintenance, and fuel source its lifetime could be anywhere between 1 to 30 years or more.
The first step you should take when determining the HVAC equipment’s age is to check the manufacturer’s label attached to the unit.
The label will often include pertinent information including:
- Manufacturer Name
- Brand Name
- Manufacture Date
- Model Number
- Serial Number
If you can’t determine the installation date of the HVAC Equipment, it’s worth checking to see if you’re nearing time for a replacement based on the manufactured date/age. You can use the model number in conjunction with the serial number of the unit in order to determine the HVAC equipment’s age.
