How Long Should An HVAC System Last?
How to get the most out of your HVAC system
For most homeowners, the HVAC system (Heating, Ventilation, & Air Conditioning) is one of the most important components of a home and its day-to-day comfort. But it’s also one of the most overlooked. HVAC systems are pricey and it’s tempting to adopt an “if I don’t look for problems, there aren’t any problems” attitude. Luckily, HVAC systems can be very resilient and last a long time, if you keep them in good shape. We’ll look at how long each part of the HVAC system can last, methods for proper upkeep, and how to tell when it is time to replace it.
How Long can each part of an HVAC system last?
This depends on several factors, including when the system was installed, how it has been maintained, and the climate of where you live (coastal areas, for example, have high levels of salt exposure that corrodes systems faster). Each part of the HVAC system has different life expectancies:
Furnace: The most expensive part of an HVAC system, the furnace can last up to 30 years with proper maintenance.
Boilers: Boilers can last up to 35 years.
Air Conditioners: Unless in a coastal area, an air conditioner can last from 10 to 20 years, 15 being the average.
Heat Pump: Similarly to air conditioners, these can last 10 to 20 years outside of coastal areas.
Ductless mini-splits: 10 to 30 years
How to make your HVAC system last longer
Regular maintenance is the best way to make your HVAC system last longer. We recommend having your system serviced at least once a year, twice a year if you have an older system. This tune-up gives your technician a chance to spot any problems or possible issues and make sure you’re getting the best air quality and energy efficiency possible. Another thing you can do is change the air filter regularly. Check your filter and furnace manual to see how often you need to change yours. Having your ducts cleaned professionally to prevent a build-up of debris and turning off the a/c at times to give the system a break are also ways to keep your system in shape.
When to Replace your HVAC system
While some months will have larger energy bills than others, if your energy bills are going up steadily, this could be a sign that your system is becoming less efficient, calling for a repair or possibly a replacement. If there is dust in your house, that may also be a sign that the HVAC system isn’t ventilating properly. If there is poor air quality, strange smells, or the machine is running loudly, you may also want to check the system. There will come a point where it is more economical to replace the system than to keep pouring money into it or allowing it to run inefficiently.
