How Long Do AC Last Before you Need to Replace Them


When it comes to AC units, most people do not realize that they will need to be replaced at some point. The question is, how long do AC last before you need to replace them? Luckily, it is not too hard to tell if your AC unit has gone bad or needs replacing. Here are some hints that you should consider replacements.

Your Air Conditioner is More Than Ten Years Old

Victor Rancour from Absolute Airflow in Westminster explains, “If your A/C is getting older, you should start preparing for the purchase of a new unit. AC units can last anywhere from 5 to 25 years, depending on the model, size, and maintenance performed.”

Unlike most appliances, air conditioners are exposed to harsh outdoor conditions that decrease their lifespan. Modern AC units usually last 15 to 20 years, while old air conditioners have a ten-year lifespan.

Your Energy Bills Have Skyrocketed

If your energy bills increase to the point that they seem unreasonable, consider replacing the AC unit. When units get older, it becomes more difficult for them to function as expected. You should start looking into AC Replacement options if this is happening to you.

A fluctuating electrical bill indicates that your AC has poor efficiency or is malfunctioning. According to experts, the monthly bills should remain in the same range if the AC operates optimally.

Detect Foul Odor from the Unit

A typical air conditioner should not emit any smell when switched on. If you detect something burning then, it is a sign of a malfunctioning system. This implies the air conditioner requires replacement or repairing.

Frequent Breakdowns in a Year

Several breakdowns of your air conditioner unit within a year indicate a severe underlying issue. If these breakdowns occur even after regular maintenance, it warrants replacing the air conditioner. It would be best to consider buying a new air conditioner to avoid the high cost of repairs and energy bills.

If the AC Uses R-22 Freon

Freon 22 is a type of refrigerant that has been banned in several countries and is phasing out in the USA. If your AC uses the R-22 Freon, it would be best to consider AC replacement options. Once it becomes illegal to produce this kind of refrigerant, replacing an older unit that uses it may be challenging.

An installation Issue

Poor installation of your air conditioner would negatively affect its functionality. Incorrect AC installation, therefore, warrants its replacement. Depending on the problem with the unit, it may still work. However, if it does not run efficiently as before, replacing it should help fix the problem.

If You Need an Hour to Cool Down the House

Old units take longer to keep up with cooling things off during hot weather or after being on for a long time. If your air conditioner takes longer than an hour to cool your home, consider replacement options.

Vibrations and Sounds from the Unit

Vibrations are indicative of loose components of the air conditioner. Consider replacing the air conditioner if vibrations and odd sounds are coming from it. The strange sounds indicate an underlying problem with the fans, motors, and blowers.

In conclusion, the lifespan of an AC unit is affected by several factors such as size, climate, location, maintenance, and climate. If you want to extend your A/C life, be sure to maintain it properly. You can call an HVAC contractor to help you troubleshoot the system if problems arise.
