In general, the lifespan of an HVAC system is between 15 and 25 years, although this can vary depending on the type of system and other factors. Even with regular maintenance and repairs, the best boilers, furnaces, heat pumps, and air conditioners will eventually stop functioning. However, more expensive models tend to last much longer. Central air units usually last 12 to 17 years with average use and proper maintenance.
Air conditioners tend to fail sooner than components that produce heat due to moisture that passes through the system and is expelled. The chemicals used in the system to cool and dehumidify the air, as well as the chemicals that the building materials of the house extract from the system, corrode the copper elements of the condenser and can cause them to erode and break. The size of the unit does not affect its lifespan unless it is not suitable for your home. For example, if you have a small 1.5-ton air conditioner trying to cool a house that really needs a 5-ton air conditioner, it will break down much faster due to overuse than a properly sized (but more expensive) unit.
On average, air conditioning systems last 10 to 15 years, while HVAC systems last 15 to 20 years. This estimate can be affected by climate, whether chemicals are used in the home, and how well the air conditioning unit is maintained. To get the most out of your unit, it is important to perform regular maintenance such as cleaning filters and air ducts. It is also recommended that you use a professional air conditioning service at least twice a year for system maintenance and overhaul.
If your air conditioning unit breaks down even after regular maintenance, it may be time to replace or repair it. Signs that indicate you may need to replace or repair your unit include strange noises coming from the unit, poor cooling performance, or an increase in energy bills. If you notice any of these signs, it is best to contact a professional for advice. In conclusion, HVAC systems typically last between 15 and 25 years depending on various factors such as type of system, climate, use of chemicals in the home, and regular maintenance.
To ensure your system lasts as long as possible, it is important to perform regular maintenance such as cleaning filters and air ducts and using a professional air conditioning service at least twice a year for system maintenance and overhaul.
