Is your air conditioner acting unusual? Chances are, it’s trying to tell you something.
The warning signs of an air conditioner’s problem can tell a lot about the sort of issue the system is afflicted with. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a specific fix. By knowing the specific symptoms, you can figure out the potential causes of the problem and determine the best course of action for repairing the AC.
While the symptoms are often unique, many cooling system issues stem from problems that can be avoided by scheduling regular air conditioning maintenance. That’s because a routine AC maintenance call includes an inspection and cleaning of your system, as well as looking for any parts that may be wearing out and need replacement or service. This helps uncover potential problems before they cause breakdowns or other issues.
Here are some of of the top AC problems and the signs you may see:
Why Is My Air Conditioner Leaking?
Air conditioning leaking water can be a widespread issue. One of the most common causes of an air conditioner leak is a clogged condensate drain line. The condensate drain line is designed to remove excess moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, debris or mold, water can back up and start to leak.
Another potential reason for water leaking from an air conditioner is a damaged or rusted drip pan, which can enable water to overflow and leak out of the unit. In addition, a refrigerant leak or a broken pump could also cause water to leak from an AC unit.
It's important to address a leaking air conditioner right away to reduce the amount of damage to your home and make sure that your air conditioning system is running efficiently. Professional air conditioner maintenance, including replacing the air filter, checking the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.
Why Is My Air Conditioner Freezing Up?
If your air conditioning is freezing up, it could stem from a variety of reasons. One typical cause of a frozen air conditioner is restricted airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This leads to a buildup of chilled air in the evaporator coil, causing it to freeze.
One more reason your air conditioner is frozen might be low refrigerant levels, which can cause the evaporator coil to become too cold and freeze. Leaking ducts or compromised insulation can also cause the buildup of cold air and cause the evaporator coil to freeze.
To fix a frozen air conditioner, it's important to switch off the air conditioning so that it can thaw completely. After the system has thawed, check the air filter, ductwork and refrigerant levels to see if anything is amiss. Regular maintenance, including exchanging the air filter and having the system inspected annually by an expert.
Why Is My Air Conditioner So Loud?
If your air conditioner is making loud noises, it might be a sign that it needs service. One frequent cause of a very loud air conditioner is a damaged fan motor or a failing fan belt. The noise could also be the result of loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.
A noisy air conditioner also might have a dirty condenser coil, which can obstruct airflow and cause the system to work harder, resulting in greater noise. Additionally, a damaged or old compressor can also cause loud noises from the air conditioner.
Why Is My Air Conditioner Not Blowing Cold Air?
One common cause of an AC not blowing cold air is a blocked air filter. A dirty air filter limit airflow, causing the evaporator coil to become extremely cold and freeze, resulting in insufficient cool air. Another possible reason for this problem is a refrigerant leak.
Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your AC. Also, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To fix this particular problem, it's important to check the air filter and replace it if necessary.
Why Is My Air Conditioner Not Working or Not Turning On?
Your air conditioning system might not start up because of a tripped circuit breaker or blown fuse. To fix this, look at the electrical panel and reset any tripped breakers or switch out any blown fuses.
The cause also could be a malfunctioning thermostat, which can prevent the air conditioner from starting. In this case, check the thermostat and change it, if required. In addition, a malfunctioning compressor, motor or capacitor can stop the air conditioner from turning on. In this case, it's best to contact a professional to inspect and repair the unit.
Why Is My Air Conditioner Making a Weird Noise?
In addition to the problem of air conditioners operating louder than they are supposed to, at times they also make peculiar noises.
One typical cause of weird noises is a deteriorating fan motor or a worn-out fan belt. These two dilemmas can produce scraping, squealing or grinding noises. Another commonly observed cause is loose parts such as screws, bolts or bearings.
Furthermore, a clogged air filter can cause whistling or wheezing noises from an air conditioner, while a refrigerant leak can make hissing or bubbling noises.
As with lots of air conditioner woes, the root cause of odd noises is often something that can be reduced by regular air conditioning maintenance.
