If you live in Las Vegas, you may be wondering how long you can expect your air conditioner to last in this particular climate. You should have an AC that is uniquely designed for our area of the country and your particular home size. The rule of thumb is that any air conditioner should last between 10-15 years. However, that’s a big variation.

If you think it’s time to schedule air conditioning service in Las Vegas, our team is here to help. We can assess your system and give you an idea of how much longer it should last based on its current age and overall system health. You can keep reading to learn more about ways to extend the life of your air conditioner so that it lasts longer than the average.

Check the HVAC Age

If you bought a home that already had an existing HVAC unit, you may want to check the installation date to get an idea of how much longer it will last. If there isn’t an installation date you can search online for the serial number and brand name. Once your air conditioner is at least 10 years old, that’s a sign that it could be time for a replacement soon.

The air conditioners that are well cared for can last even longer, usually up to 15 years. If you’re not sure about the condition of your unit, our team can come out and inspect it to give you an idea as to how well it has been cared for. We can also make recommendations for maintenance steps that can extend its life.


When you ask the question, How long will my AC last? how long it’ll last doesn’t necessarily mean how long will it work until it breaks down and stops working completely. You need to consider the overall performance and energy efficiency of your air conditioner when you think about how long it will “last.” If your air conditioner becomes too expensive to operate or needs frequent repairs, that’s a sign that your AC has reached the end of its life, even if it’s still running. Investing in a new unit can reduce your energy costs by anywhere from 20% to 50% each year.

Air Quality

You also want to think about the air quality in your home. Is your air conditioner helping to manage the humidity? Is it working well enough to reduce allergens in the air like mold? If your air quality is bad, your HVAC unit may be to blame.

It may be that your older unit simply cannot work as well as a new unit does. We typically see air conditioners begin to decline after the 10-year mark. If you schedule annual maintenance, your air conditioner could easily last for 15 years or longer with great efficiency and indoor air quality. It all depends on how well you care for your unit.
