According to the United States Department of Energy, the estimated lifespan of an air conditioner is anywhere between ten to fifteen years. Typically, a decade after, your air conditioner won't work as efficiently as it used to and might need to be replaced.
However, service duration is not the only factor you need to consider when replacing your AC unit. For instance, if you notice that your AC has been malfunctioning more than usual, it's another telltale sign to get an AC unit online.
Other signs that indicate it's time to replace your air conditioner unit include:
Sign #01: Unusually high energy bills.
A dramatic and unexplained spike in your home energy bill can be a clear indication of a malfunctioning AC unit. Unless there are significant changes in your home's energy use, your monthly energy bill should be easily predictable.
If you get an extremely high energy bill, even if there are no drastic changes in your energy usage, one of the first things you should examine is your AC unit. Most modern air conditioners today will require less energy to work efficiently.
If you have a unit that's more than a decade old, it might be a good idea to invest in an energy-efficient one. The excellent news is energy-efficient ones can help you save as much as 40% of your usual cooling energy cost.
Sign #02: Your AC unit produces odd sounds.
If your AC unit produces odd and unusually loud sounds, it can be a foolproof sign you need to have it replaced. Noises like squealing, rattling, and other banging sounds that occur when you turn on your system is not something you should ignore.
When you start to hear unusual sounds, it is recommended that you check with a seasoned technician and have the unit checked right away. Often, noises are caused by belts that have slipped out of place. It can also be caused by a broken motor bearing.
Sign #03: Your unit is blowing warm air.
At times, the temperature can get as high as 90F during summers. The last thing you want is an AC unit that blows warm air. Warm air is often an indicator of a malfunctioning compressor.
It can also point to an AC unit that's low on refrigerant. In some instances, warm air is blown by the AC unit when the ducts of the unit pull air from the attic space rather than the compressor.
If you notice your unit blowing warm air, call a professional right away to have the unit checked. If the problem cannot be repaired, investing in a new unit is your next option.
Sign #04: You are not getting any cold air.
Not getting any cold air from your AC unit should be a cause of concern. Common causes of this problem include low refrigerant levels, electrical fault, and a possible broken compressor.
Again, your first recourse should be to have the unit checked by a professional. If the repair required is extensive, replacing the unit is your best option.
Sign #05: There are refrigerant leaks and moisture buildup.
If you notice any moisture buildup or leakage, it is possible that you have a refrigerant leak. Leaks can undermine the efficiency and performance of your unit. It can also cause your annual cooling cost to spike.
It is crucial to remember that moisture buildup can become a potential health hazard as it can become a breeding ground for mold. That said, if you notice any leaks around your AC, replacing it is deemed ideal.
Sign #06: Your unit uses R-22 Freon.
Freon is no longer produced in many countries, including the United States, since January 1, 2020. If your unit is a decade old (or older), there is a high probability that it uses the R-22 Freon.
The R-22 refrigerant has been used for car AC systems, central air conditioners, and other refrigeration equipment for ages already. While it is known to efficiently absorb and remove heat from spaces, some studies indicated that it has adverse effects on the environment.
If your current unit uses Freon, it would be best to replace it with a new one if it breaks down. Check out the nameplate on your unit to determine the type of refrigerant used.
Final Thoughts
An efficient AC unit should enhance your home's comfort and save you money at the same time. If replacing your AC unit is the best option for your case, it would be best to check with an expert to help ensure the unit is installed correctly and everything is working as it should.
