How Long Does Air Conditioning Last?

air conditioning contral

Your air conditioning unit is an integral part of your home, especially in a climate where summer temperatures can reach dangerous, triple-digit highs. When you install a new unit, you want to make sure it’s going to offer peak performance, on demand, and stand the test of time. How long do AC units typically last?

Many systems include up to a 10-year warranty, so you can reasonably expect them to last at least a decade. Most are rated to continue working for about 10-15 years. The longevity of your system may depend on several factors, including the equipment you choose and how much you use it, but with proper maintenance that includes annual inspection, cleaning, and repairs, you could get 20 or more years out of your unit.

During that time, however, certain components may degrade faster than others and require repair or replacement. This is still less expensive than replacing the entire unit, but you should be aware of components that may fail before the unit itself has reached the end of its usable life.

How Long Do Air Conditioner Compressors Last?

The compressor does a lot of heavy lifting to cool your air, pressurizing refrigerant before sending it on to the condenser for cooling. It’s comprised of several parts that spring into action when you adjust the thermostat and demand cold air.

It’s no surprise then, that you could end up needing repairs to the compressor before the entire system needs replacement. Generally speaking, compressors last about 12-15 years, especially with proper maintenance and repair.

How Long do HVAC Capacitors Last?

The capacitor’s job is to kick-start your cooling system when you demand air and deliver the continuous power needed to keep it running. This powerhouse of a part could last up to 20 years, but several factors may truncate its’ lifespan. If your capacitor is undersized or your air conditioner cycles on too frequently, for example, your capacitor may expire early and require replacement.

Why is My AC Blowing Warm Air?

Even with proper maintenance, parts will suffer wear over time and eventually break down, resulting in problems with your AC. One issue you’ll want to correct immediately is warm air blowing from your vents when you’ve set your thermostat to cold. What causes this predicament?

There are a couple of potential reasons, such as a refrigerant leak or a failing compressor, or there could be a problem with your thermostat. When facing this problem, you’ll want to contact your trusted HVAC service provider to inspect your system, diagnose the problem, and make any needed repairs.

Why is My AC Compressor Failing?

Certain circumstances, like excessive wear, or equipment that’s the wrong size for your home, can shorten the life of your compressor. With early detection, repairs may be possible, but at some point, replacing the compressor may be necessary.
