How long do AC units last? Some designs only last five to ten years. Others might provide you with up to 20 years of performance at your property in Woodstock, Illinois, but this depends on quite a few factors to come together.

At WeatherWise Heating & Cooling, Inc., our AC maintenance professionals know how to ensure maximum HVAC system longevity. The secret lies in regular upkeep and timely AC repair in Woodstock, IL. Learn more about the average air conditioner life expectancy below, including some important signs that your AC needs replacement.

The Average Lifespan of Different Types of Air Conditioners in Woodstock, Illinois

The lifespan of your air conditioner depends heavily on the design of the unit. For example:

Mini-Split Air Conditioners Have the Longest Lifespan

Ductless mini-splits are popular in Woodstock, IL. These systems can provide both heating and cooling capabilities. 

Your ductless mini-split system might last 15 to 20 years when a qualified installer puts it in. 

Central Air Conditioners Can Provide Fairly Decent Lifespans

Central air conditioning durability is almost as long as with a mini-split system. Most central AC units will last 12 to 15 years, although some will last as long as 20 years with proper maintenance. 

A central air conditioner is the most common option for homes and businesses in Woodstock, Illinois. Northeastern Illinois’s humid continental climate can make your home feel especially uncomfortable during a hot, humid summer day. Your central AC system will efficiently balance humidity while cooling every room.

Window AC Units Sport the Shortest Lifespan

How long do AC units last when you rely primarily on window air conditioners? A window air conditioner might only last five to ten years. 

When you leave these units in the window all winter, you expose them to harsh winter weather instead of storing them. You can expect these conditions to shorten a unit’s lifespan.

Factors That Shorten an Air Conditioner’s Lifespan and How To Avoid Them

When you see any signs that your air conditioner is malfunctioning, call for immediate repairs. Failing to address these problems with timely repairs is a common mistake that undoubtedly shortens the system’s lifespan.

Some homeowners may worry about the cost of air conditioning repairs, delaying much-needed help from a repair technician. However, our technicians often find that property owners who ignore a minor problem incur much costlier repairs soon afterward. A minor repair is nothing compared to a complete system failure if you’re trying to avoid a pricey replacement.

In that same sense, failing to care for your cooling system shortens its lifespan. When evaporator coils, condenser coils, and air filters choke with dust and pollen, the air conditioner experiences significant stress while running. The Woodstock, IL, region can have high pollen counts during spring and summer, so annual cleanings, regular lubrication, and quarterly filter changes are important.

Know When To Replace AC Units and Save

How long do AC units last? What are some top signs that it might be time to replace yours? The first consideration is when your system needs frequent repairs. 

Is the air conditioner near the end of its expected lifespan? Are the costs to repair it creeping higher each time you call our technician for service? You might be better off putting that money toward a more efficient replacement unit.

Pay attention to an older air conditioner that suddenly struggles to keep up with the summer heat in Woodstock, IL. Summer’s high temperatures here reach the 90s. A well-functioning air conditioner should have no problem keeping your home or business cool, though.

If you’re ever unsure about replacements, our local air conditioning technicians can provide advice. They can inspect your current system and let you know when replacing your older air conditioner is the right choice.
