Like other aspects of an HVAC system, the average lifespan for central air conditioners ranges from 15 to 20 years.
While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Modern air conditioners can last between 15-20 years, and older air conditioners last around 10-12 years. The health and efficiency of your A/C depends on a number of factors, including whether or not you properly maintained the unit throughout its lifetime.
The average unit has a lifespan of 12-15 years. If you get 15 years of cooling power out of your air conditioning unit, consider that a successful life!
Carrier air conditioners are highly rated for durability, energy efficiency, and performance. Homeowners frequently praise Carrier's reliability, quiet operation in premium models, and long-term energy savings.
Central air conditioning systems can last anywhere between 10 to 30 years, with most averaging around 10 to 15 years total (1). Keep in mind, the lifespan of your air conditioner depends on how much you use it, your local climate, what type of AC it is, and if your house is well insulated and air sealed.
The average lifespan of an air conditioning system is 10-15 years. Central air conditioner lifespan is one of the more important factors to consider when planning to invest in a replacement unit. If your unit is close to ten years old or older, you may want to consider replacing it instead of repairing it.
Average New AC Unit Costs
The average cost of installing a new central air conditioner in 2024, including equipment and labor costs, is $5,750 for a 3-ton unit in a 2,000-square-foot home. On average, a new AC unit cost will fall between $3,300 and $7,800.
Air conditioner is over 15 years old
The typical lifespan of an air conditioner is around 15 years, at which time it must be changed. Some air conditioners may work well beyond their designed lifespan, but they become less efficient with time.
The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today. This is why in some cases, this constant running can be dangerous.
Heat pumps: 10 to 16 years. Furnaces and boilers: 15 to 20 years. Geothermal heat pumps: 25 to 30 years; ground loops will last upwards of 50 years. Solar: 25 to 30 years.
Carrier air conditioners, for example, offer a variety of energy efficiency or SEER2* ratings, various types of comfort-enhancing technologies and even sound ratings. Installed costs might range from anywhere between $3,000 to $15,000 or more.
During spring and fall, most people aren't running their HVAC systems as often which, in turn, means HVAC companies are not as busy and are not selling as many new units. This drop in demand enables them to offer deals on their services and equipment.
Homeowners insurance covers HVAC systems when the damage is a result of a covered disaster or peril, including high winds, fallen trees, theft, hail or even a fire. So if lightning strikes your unit and damages its electrical components, your homeowners insurance policy would probably cover it.
How long should ductwork last? You should replace your ductwork every 15 years because the materials deteriorate over time, impacting HVAC performance and indoor air quality.
How much will a new AC unit save me? How much you can save with a new AC unit will depend on your old unit, the replacement model, how much you use your air conditioning, and the cost of electricity where you live. Estimates vary from 10% to 50% savings on your air conditioning costs per year.
Newer systems often use pleated filters, also rectangular with a depth of about one inch. You should replace these about every 90 days if you have no allergies, but AC pros typically recommend every 45 days for max efficiency.
If everyone in your household is either at work or school, then turning the temperature to 78-80 degrees will save you a chunk of change when the energy bill arrives. The one consideration to keep in mind is if you have four-legged friends at home. If this is the case, a temperature setting in the 76-78 range is best.
