How Long Can I Expect My Air Conditioner to Last?

Unlocking the Lifespan of Your Air Conditioner: A Guide to AC Longevity

Whether you’ve recently purchased a new air conditioning system, or have one that’s several years old, an important question you may be asking is, “How long do AC units last?” Truthfully, there are many impacting factors involved when it comes to determining a cooling system’s longevity. Our experts have put together some influencing factors to AC life cycle length.

Determinants of AC Longevity

Here is a list of factors to consider when it comes to estimating the life cycle of your AC system:

Climate: Because we live in the Houston area, our air conditioning systems are going to get used regularly and for many months. We are considered the most air conditioned city in the United State and for good reason. Your Houston-based AC system won’t last as long as a unit in northern cities where the summers are more temperate and shorter than ours. 

Quality of the Equipment: High quality and 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 types of refrigerant that are non-ozone depleting all help create a more efficient system. You may be surprised to learn that today’s air conditioners use anywhere between 30 and 50 percent less energy than those manufactured in the 1970s. 

Quality of the Installation: A poorly designed and installed AC system will have problems regularly because of power issues, ventilation issues, capacity taxing, and poor placement of both the indoor and outdoor units. 

Quality of Your Home Insulation: Your home’s ability to deflect heat and keep cool air inside is going to determine how hard your AC system has to work to keep you comfortable. 

What Can I Do to Increase the Lifespan of My Cooling System?

You can make sure your AC unit lasts longer and withstands the test of time by taking some of these measures:

• Install High Quality AC Equipment: 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. 
• Get Professional, High Quality Installation: 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, outdoor unit placement are all parts of a professionally installed AC system. 
• Keep your AC System Tuned: 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 contract 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. 
• Replace Air Filters Regularly: 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.
