It's important to be aware of how long air conditioners last, so you don't get the unwelcome surprise of a broken air conditioner in the peak of the summer heat. In general, air conditioners that are properly maintained can last 15 to 20 years.
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.
On average, you can only expect about 15 years of reliable service from a central AC system. And that's only if you maintain your system well. So, if your home has an AC that's 20 years old or older, it's likely living on borrowed time. Here are all the reasons to replace your home's 20-year-old air conditioner.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
Turning off your AC when it's not cooling is more than a precaution; it's a necessary first step in troubleshooting and protecting your system from further damage. By understanding when to perform simple checks and when to call in the experts, you ensure your air conditioner remains a reliable refuge from the heat.
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.
Less than 50% of the replacement cost: If your HVAC equipment is under 10 years old and the repair bill is less than half of the cost to replace it, a repair is most likely the right choice.
How Long Does an AC Compressor Last? An AC compressor typically lasts between 7-18 years. The lifespan of an AC compressor is largely dependent on how well it is maintained and how often it's used.
Better pricing: Since there's less demand for HVAC system replacement in spring and fall, your HVAC contractor might even offer their own savings incentives.
This will reduce the strain placed on your AC unit, allowing it to run more efficiently, and lowering your energy bills. Bottom line, while it's not necessary to give your AC unit rest breaks during summer, its maintenance is essential.
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.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
If your AC is newer, you may be able to replace just the outdoor unit. In many cases, this could lead to decreased energy efficiency or early AC failure. Installing a new AC costs between $3,800 to $7,500. Replacing just the outdoor unit can sometimes void the warranty.

One is when the unit is cheap, and the other is when installation is cheap. The best time to split the difference is spring. Air conditioning units are cheapest during the cold months just before the manufacturers release their new models.
Average Costs for Installing an HVAC System with Ductwork
2-ton HVAC system: $8,000-$12,000, depending on the brand. 3-ton HVAC system: $9,500-$13,500, depending on the brand.
Overheating is a common cause of compressor failure, and there are many factors at play. If direct sunlight falls on your outdoor unit and there is inadequate ventilation around it, it makes your unit's compressor overheated. High voltages can also damage the motor causing the compressor to overheat.
Airflow is lower: Lower airflow coming from the air conditioner often means a weakening compressor. The AC is overheating: Are you experiencing frequent circuit breaker trips when the AC is on? This often means the compressor motor is overheating and overloading the circuit breaker.
The average cost for an AC compressor is $1,200, but you might pay between $800 and $2,300 depending on your unit type and brand. On average, AC compressor costs range from $800 to $2,300, with most folks paying $1,200 for a new one.
