According to a recent report, the people of Dallas, Texas, spend 11.87 cents per kWh. But this cost can be easily reduced by replacing an energy-efficient cooling system. As a homeowner, you must know your air conditioner lifespan. Because as the air conditioner ages, it starts to consume more electricity and perform less.

This article will talk about the HVAC system’s lifespan and when to replace your heating and cooling system instead of repairing the unit again.


Air Conditioner Life & How Long Does a Central Air Conditioner Last

To find out the lifespan of an air conditioner, you’ll have to consider these factors –

Air Conditioner Types & Its Impact on AC Life

Air conditioner lifespan varies from one air conditioner type to another. For example, when you buy a mini-split air conditioner for your home or office space, it’ll last for about 15 to 20 years. On the other hand, cheap AC units such as portable or window air conditioning systems will last only about 5 to 10 years.

How Long do Central AC Unit Last

On average, a central air conditioning system will last more than 20 years. And if you maintain your central cooling system properly, you can use it for about 25 years or more.

Central air conditioners have a higher SEER rating and high capacity. If you compare the central air conditioner with other cooling systems, it’s the most affordable HVAC system in the market.

Effect of Usage on Goodman, Carrier or Trane Air Conditioner Life Expectancy

As Dallas is relatively hotter than other states in the US, you’ll be using your Goodman, Carrier or Trane HVAC system at maximum capacity most of the time. But when you use your HVAC system at maximum potential all the time, it’ll reduce the life expectancy of an air conditioner.

Running AC on Maximum Capacity and How Long Does a Central Air Unit Last

Usually, homeowners in hotter climate areas such as Dallas use their central air conditioner at maximum capacity for at least four months a year. When the AC unit runs at maximum capacity, it creates a lot of pressure on the unit’s internal parts. As a result, your AC unit will have more wear and tear and may need frequent repairs. No matter how well maintained your HVAC system is, the life span of your air conditioner will be reduced, and you may have to replace your HVAC unit earlier.

What Should be Done to Prolong Air Conditioner Life Expectancy?

To increase the lifespan of your air conditioner, you’ll have to buy a bigger cooling system for your space. When you buy a bigger air conditioner, it won’t have to run at maximum capacity, and it’ll be able to give you benefits such as energy savings, maximum comfort, etc. in the long run. Besides, when you buy a bigger air conditioner, your AC unit will become energy-efficient and consume less electricity.

However, while buying a bigger AC unit for your space, it’s recommended that you consult with an HVAC professional. Because if you buy an excessively large AC unit, it’ll compromise your comfort, and it may damage your AC unit.

When Should You Replace or Repair Your Air Conditioner to Increase the AC Life?

With regular AC maintenance checkups, you can increase your air conditioner unit’s lifespan by few years. However, if the air conditioning unit is over 15 years, there is no point in regular maintenance checkups. Because after 15 to 20 years, all the parts of an AC unit start to perform poorly, and even if you keep your AC well-maintained, you won’t see a drastic change in performance. Besides, AC maintenance doesn’t come cheap. That’s why if the AC is more than 15 years old, you should start thinking about replacing your unit.


FAQs about How Long Does Central Air Last

Is It Viable to Use a Cooling System Up to 30 Years & How Long Does Central A/C Last?

As I mentioned, central air conditioners usually last about 20 to 25 years. However, it’s not viable to use a central air conditioner for up to 30 years. Because after 20 years, you’ll notice that your cooling system has started performing poorly. As time pass by, you’ll see other signs such as your AC isn’t cooling, humidity problem, etc. That’s why you should replace your air conditioner when it crosses the average lifespan.

How Long Does a Central A/C Unit Last & What is the Average Lifespan?

The average lifespan of an AC will vary from one type to another. If you have a portable AC unit, it’ll last only 5 to 10 years. On the other hand, if you have a window AC unit, its average lifespan is about 10 years.

Again, if you opt for an expensive AC unit such as mini-split air conditioners or a central air conditioning system, the average lifespan will be 15 and 20 years, respectively.

What is the Trane Heat Pump Life Expectancy?

Trane heat pumps are one of the best in the market, and their life expectancy is more than 15 years. As long as you maintain your Trane heat pump, you can increase this lifespan to 20 years.

How Long Do Carrier Air Conditioners Last?

You can expect your Carrier air conditioning unit to last about 10 years. However, it completely depends on how you maintain your Carrier AC unit.

How Long Does a Trane Furnace Last?

All the Trane products in the market are top-notch. Like the Trane heat pump, the average lifespan of the Trane furnace is 10 to 15 years.
