Find a full guide on your Air Conditioner Lifespan, what can affect it and what kind of AC maintenance you need.
Whether you've recently invested in a new air conditioning system or are nursing an older unit through another sweltering summer, a crucial question inevitably arises: "How long do AC units last?" The truth is, numerous factors influence an air conditioner's longevity. This comprehensive guide, put together by our team of experts, will delve into the determinants of an air conditioner lifespan and provide actionable tips to maximize the life of your unit.
The average air conditioner lifespan is between 15 and 20 years. However, this is just an estimate. With proper maintenance, some units can last longer, while neglected systems may fail in as little as 10 years. In coastal areas, the salty air can corrode components, potentially shortening the lifespan to as little as 7 to 10 years. Conversely, in milder climates where the AC is used less frequently, a well-maintained unit could last for more than 20 years. The key takeaway is that while there's an average, the actual air conditioner lifespan of your unit is not set in stone and can be influenced by a variety of factors.
The climate you live in plays a significant role in your air conditioner lifespan. In a place like Houston, where air conditioning systems are used regularly for many months of the year, the constant use puts a great deal of stress on the unit. Houston is even considered the most air-conditioned city in the United States, and for good reason. An AC system in Houston will likely not last as long as a unit in a northern city with more temperate and shorter summers. The more you use your air conditioner, the faster its components will wear out, which is why it's so important to invest in a high-quality system and keep up with regular maintenance.
High-quality, modern AC equipment is manufactured to be as efficient and long-lasting as possible. Advances in technology to meet SEER2 specifications and the use of new, non-ozone-depleting refrigerants all contribute to a more efficient and durable system. In fact, you may be surprised to learn that today’s air conditioners use between 30 and 50 percent less energy than those manufactured in the 1970s. When you're in the market for a new air conditioner, it's worth investing in a high-quality unit from a reputable brand. While the upfront cost may be higher, the long-term savings in energy bills and repair costs, as well as the extended air conditioner lifespan, make it a worthwhile investment.
A poorly designed and installed AC system will be plagued with problems from the start. Issues such as power problems, ventilation issues, capacity taxing, and poor placement of both the indoor and outdoor units can all lead to a shorter air conditioner lifespan. That's why it's crucial to have your AC system installed by a qualified and experienced HVAC professional. A professional will ensure that your system is properly sized for your home, that all the components are installed correctly, and that the system is running at peak efficiency.

Your home’s ability to deflect heat and keep cool air inside will determine how hard your AC system has to work to keep you comfortable. Poor insulation, leaky windows, and unsealed doors will all allow cool air to escape, forcing your AC unit to run longer and work harder. This not only increases your energy bills but also puts a great deal of strain on your system, which can shorten its air conditioner lifespan. By improving your home's insulation, you can reduce the workload on your AC unit and help it last longer.
You can make sure your AC unit lasts longer and withstands the test of time by taking some of these measures:
If you are installing or replacing your current system, make sure you get the highest quality equipment your budget will allow. Houston summers are brutal, and you will be happier with the reliability and efficiency of quality AC equipment. A high-quality unit will not only last longer but will also provide better comfort and lower energy bills.
A qualified HVAC professional will make sure your system is properly sized for the square footage of your house and for your needs. A system that is too small will tax your system, and a larger system will also struggle to find a comfortable climate. Power sources, existing ductwork, and outdoor unit placement are all parts of a professionally installed AC system. A professional installation will ensure that your system runs efficiently and effectively, which will help to extend its air conditioner lifespan.
One of the best ways you can extend the life of your AC unit is by making sure it gets the maintenance it needs. Annual maintenance from a local, reputable HVAC contractor like Champion & Nash helps ensure your system is operating at its most efficient and effective before Houston gets deep into those hot days of July and August. During a maintenance visit, a technician will clean the coils, check the refrigerant levels, and inspect all the components of your system to make sure they are in good working order.

You can help extend the life of your AC system by checking and replacing your unit's air filters. You probably will want to do this once a month during the late spring through early fall. A clogged air filter will restrict airflow, forcing your AC unit to work harder to cool your home. This not only increases your energy bills but also puts a strain on your system, which can lead to premature wear and tear.
Even with the best care, your air conditioner will eventually need to be replaced. Here are some signs to look for that may indicate your AC unit is nearing the end of its air conditioner lifespan:

When your air conditioner starts to fail, you'll be faced with the decision of whether to repair or replace it. This can be a difficult decision, but there are a few factors to consider that can help you make the right choice. If your unit is relatively new and the repair is minor, it's probably worth repairing. However, if your unit is older and the repair is major, it may be more cost-effective to replace it. To help you make an informed decision, we've put together a guide on AC Repair vs. Replacement.
Regularly changing your air filters and having your ductwork cleaned can significantly improve your indoor air quality. For more tips, check out our article on how HVAC experts can improve your indoor air quality.
SEER2 (Seasonal Energy Efficiency Ratio 2) is a new standard for measuring the efficiency of air conditioners. The higher the SEER2 rating, the more efficient the unit.
It's recommended to have your AC unit serviced at least once a year, preferably in the spring before the start of the cooling season. This will help to ensure that your unit is running at peak efficiency and can help to extend its air conditioner lifespan.
