What is the Lifespan of an Air Conditioner?

Lifespan of AC

What is the lifespan of an air conditioner, you ask? Central air conditioners typically last from 12 to 15 years if it is properly installed and maintained. The AC lifespan may be reduced if its capacity is not properly matched to the cooling load of the home. If your air conditioner is too big for the space, it will “short-cycle.” This means the AC is turning on and off rapidly, inflicting excessive wear and tear on the compressor.

Since the compressor is the most costly part in the system, a worn-out compressor in a unit that’s outlived its warranty is usually a deal-breaker that warrants upgrading to a new, more energy-efficient air conditioner rather that repairing the existing unit.

Factors That Affect Your AC Lifespan

To start, ask yourself these few questions:

What brand was installed?

Some firms are known for making remarkably durable units such as Rheem and Mitsubishi. The quality of the brand is a factor in the anticipated life expectancy.

Was the machine properly maintained?

Proper care and maintenance of your air conditioner in Lutz will add years to its useful life. If you have taken good care of your unit, you shouldn’t need to replace it as soon.

How much does the unit run?

Some Trinity homeowners are only here for a portion of the year while others live here year-round. If their air conditioner runs regularly for the majority of the year it will incur regular wear and tear more rapidly that may shorten its lifespan.

How to Prolong the Life of Your AC


Proper air circulation plays a critical role in enabling your AC to effortlessly cool your home. This makes vents important in maintaining the longevity of your unit. A blocked vent keeps the air from flowing and affects indoor air quality. It also forces your AC to work overtime to cool the space. To prevent this from happening, regularly check your vents for any obstruction so air can circulate freely inside your home.

As a bonus, checking your vents can help cut down monthly power bills since your AC won’t be working twice as hard to keep your room at the right temperature.


Your AC unit’s lifespan greatly relies on proper maintenance and cleanliness. In addition to having professionals routinely check your AC, proactively assess your outdoor unit because it accumulates dust, dirt, and debris. Getting rid of leaves or fallen tree branches on your exteriors unit can help you stay away from possible repairs.


A blocked drain line causes water to back up into your unit and cause leaks. When left unnoticed, leaks can lead to minor and major mechanical problems. To avoid leaks or water backflow, regularly check your drain line at least every year.

You can clean your drain line by flushing a cup of chlorine bleach into the line before cleaning it with water. If the drain line is clogged by too much dirt, get professional help. This prevents leaks from causing bigger and more expensive AC problems.


The need to replace your filter mainly depends on two factors: how you use your unit and who occupies your home. For example, if you regularly use your AC and you have pets inside your home, it’s best that you change your filter at least every month. Change the filter every 6 to 12 months if your AC unit is installed in a vacation home that is seldom used.

A new filter maintains the efficiency of your unit. Besides keeping dust and debris out, your unit’s workload easier with a clean AC filter. Since it greatly influences your unit’s air intake, it’s important that you check your filter so you can see if it’s time to clean it or replace it with a new one.


Prolonging your AC unit’s lifespan involves yearly tune-ups, which typically includes inspecting, cleaning, calibrating and evaluating your unit. Tune-ups save you from expensive repairs since it diagnoses problems before they get bigger.

Besides maintaining the health of your unit and helping it last longer, a good HVAC company can help you optimize your AC’s efficiency by spotting mechanical problems before they happen. This extends the lifespan of an air conditioner.
