No home can truly be comfortable without a functioning AC unit. With that in mind, according to the U.S. Department of Energy, the lifespan of a central air conditioner is about 15 to 20 years. So, if your AC unit is older than that, it may be time to consider replacing it. Your HVAC system may show signs of needing replacement before its expected lifespan cycle is over. Let’s review how to tell when it’s time for a new AC installation.
1. Higher Energy Bills
As your AC unit ages, it can become less efficient and require more energy. This situation can lead to higher energy bills as your unit struggles to keep up with the temperature demands of your home. Look out for a bill increase of 10-25% over the same time period from the previous year.
2. Increased Repairs
If you’re constantly repairing your old AC unit, it may be time to consider replacing it. With an older system, repair costs quickly add up and eventually exceed the cost of a new installation. If you find yourself repairing the same components over and over again, then it’s probably time for a replacement.
3. Excessive Noise
When your AC is running, you should only hear a subtle humming. If your AC system is shaking and making more noise than usual, it most likely has a faulty part. An older system may start making strange noises due to worn-out parts or broken components. When you hear loud or strange noises from your AC unit, contact an HVAC technician right away. Noise may come from faulty fan belts, bearings, motors, or other components within the unit.
4. Unusual Smells
There’s no logical reason for a functioning AC to smell bad. You should be alarmed when an odor comes from the unit. If you start noticing unpleasant smells, it needs attention. Common smells associated with faulty air conditioning systems include musty odors or burning smells.
5. Poor Airflow or Wrong Temperature
Your air conditioner should provide consistent airflow throughout your home without any issues. If you notice weak airflow or inconsistent temperatures in different rooms of the house, this could mean that there are problems with the blower motor or compressor. If you notice your AC producing air at the wrong temperature, this is another sign of a broken system. The last thing you want is to have hot air blowing on you during the dead of summer. Both of these instances require a repair service to fix them.
6. Age of the System
The age of your AC system can also be an indication that it may need to be replaced. A unit over 15 to 20 years old, is most likely outdated in terms of energy efficiency and environmental friendliness. Newer models are much more efficient and can help you save on energy costs in the long run.
7. Breathing Problems or Allergic Reactions
If you or your family members start noticing breathing problems or allergic reactions while the AC is running, this could be an indication of mold or bacteria buildup in the system. An older AC unit can experience problems with condensate buildup. You can have it checked first, but if this is the case, then it may be time for a new AC installation.
8. Doesn’t Have Green Features
If your AC system is outdated and doesn’t have green features, it may be time to upgrade to a newer model. Modern air conditioners are much more efficient in terms of energy consumption and don’t require as much electricity or resources to run properly. Look for an AC unit with a high SEER rating that can help you save on energy costs in the long run. Green-friendly updates may also give you government tax credits and rebates.
Keep an eye out for these signs so you can tell when it’s time to replace your old air conditioning system. If any of these issues sound familiar, a professional HVAC technician can provide a consultation and discuss the best options for your AC system. An AC installation can be an expensive investment, but it’s worth it in the long run when you consider all the benefits that come with it.
