How Long Do Air Conditioners Last?

air-conditioning-repairAir conditioners are expensive investments in your home and they should be treated as such. With proper care and attention, they can last a long time, and save you money with improved efficiency and lower bills in the process. Every air conditioner comes with a warranty, typically lasting around 8-12 years. Ideally, your system will last for many years beyond that, and while nothing is guaranteed, you can take a number of steps to prolong the lifespan of your air conditioner.


How Long Do AC Units Last?

How long do air conditioners last? A central air conditioner system is engineered with a lifespan of 15 to 20 years. However, the lifespan of your system will be dependent on a variety of variables such as operational patterns, brand, usage, and climate conditions. If you’re looking to prolong the life of your system, we recommend hiring a professional to perform an air conditioner tune-up at least once a year. 

While an energy-efficient air conditioner may have a longer lifespan when compared to a budget friendly model, all types of systems have a limited lifespan. The only way to extend the life of your air conditioner is to perform annual tune-ups and cleanings.

It Starts With Maintenance

A yearly maintenance session makes a great way to cut down on wear and tear, and extend the life of your system. Performing consistent air conditioner tune-ups  will also help you lower your monthly bills. The process lets the technician correct all of those little problems that don’t merit a repair call on their own: things like clogged filters, frayed wires and loose bolts can add up to greater strain on the system (and more serious breakdowns) if they aren’t addressed.

When applied over time, maintenance sessions extend the lifespan of the various components in your air conditioner and by default the life of the air conditioner itself. They also improve the air conditioner’s performance – cutting down on monthly bills in the process – and if there are lingering troubles that might bite you later on down the road, a maintenance session is the perfect time to spot them and schedule repairs before the damage has a chance to spread.

Look for Quality Upgrades

Would adding an air purifier or energy-efficient thermostat to your home impact how long an air conditioner lasts? You can further extend your air conditioner’s lifespan with an upgrade that can help improve its effectiveness and thus cut down on strain. Options are varied, and since every home is unique, what works best for yours may depend. But some of the possible options include the following:

Air Cleaners

Dust and dirt can cause a lot of problems for your air conditioner: increasing friction on moving parts and similarly adding to the system’s workload. An electronic air cleaner can solve that problem quickly, as well as providing healthier air for your home overall.

Zone Control Systems

Zone control systems divide your ductwork into sections, allowing each section to be cooled independently of the others. It also lets you run the air in parts of the home you’re occupying, while turning it off in parts of the home you aren’t.


New smart thermostats will analyze your cooling patterns and make little adjustments to help your air conditioner do its job without expending quite so much energy.
