During the hot summer months, your air conditioner is the key to comfort and health for your family. As a result, it should always function at peak efficiency. However, even the best air conditioning units on the market will need an AC repair service occasionally. There are several signs that can serve as an indication that your AC is broken or almost breaking down. Recognizing these signs and immediately acting can prevent an extremely costly system repair or replacement. Read on to learn more about these telltale signs.
1. Your AC Is Blowing Warm Air
Your AC should always blow cold air, never warm or hot air. If you notice the system blowing warm air, check the thermostat first, and ensure it is set appropriately. Sometimes, warm air blowing from your system may result from a simple thermostat mistake. If the thermostat is set correctly and warm air is still blowing from the vents, your AC probably has an underlying issue.
For instance, warm air could blow from your AC because the refrigerant is leaking. The refrigerant absorbs heat inside your home and expels it outside. If there is a refrigerant leak within your system, your unit will be unable to blow any cold air into your home. The best way you can tell if there is a refrigerant leak is if the evaporator coils are frosted over, but the AC is blowing warm air inside your home.
Additionally, your AC can blow warm air due to dirty evaporator coils. These coils are located in the indoor air handler unit and play a critical role in how your system cools the air. If these coils become dirty or clogged, their ability to cool air properly is restricted.
2. Insufficient Airflow
Poor airflow can also be a conclusive sign that your AC is broken or that a blockage prevents the air from moving freely through the ductwork. In this case, a clogged air filter, a broken motor, or a more serious issue may be to blame. One way to prevent airflow issues with your AC is by regularly changing the air filters. These should be changed at least once every 90 days.
3. High Humidity
Most modern ACs are designed to regulate humidity levels automatically inside a home. Thus, if you notice high humidity inside your home, it could be an indication that something is wrong with your system. You can tell if your home has higher humidity levels in several ways. You could observe visible condensation on surfaces like windows, mirrors, or any surface that is cooler in temperature than the surrounding air. Also, high humidity can cause the paint on your walls or ceilings to peel off, which is more prevalent in bathrooms lacking proper ventilation. Another way you can tell your home is excessively humid is if it smells musty or moldy. Mold and bacteria tend to love humid environments. When the bacteria and mold become airborne, they will adversely affect your indoor air quality.
4. Bizarre Noises
Air conditioners are designed to offer a comfortable environment inside your home. Newer ACs are quieter than older ACs. Loud, sudden, or strange noises can signify problems with your system. For instance, rattling noises can indicate a loose part within your system. A grinding sound, on the other hand, can indicate a more serious problem. These strange noises usually do not self-diagnose, and leaving them unattended for some time can lead to more damage within your system.
The above signs are some of the indicators that something is seriously wrong with your air conditioner. It’s important not to ignore an unusual issue with your system, even if it is small. When some problems are left unaddressed for a long time, they lead to more damage that could even render your whole system useless. In the end, you may need a replacement. Ensure that your AC receives routine maintenance so that you can extend its lifespan.
