Common Air Conditioner Problems and How to Fix Them
During hot summer days, air conditioning is a necessary comfort. However, like any other piece of equipment, air conditioners can experience problems. Some of these problems are common, and with a little bit of troubleshooting, you can easily fix them yourself. Here are some common air conditioner problems and how to fix them.
Dirty Air Filters
One of the most common problems with air conditioners is dirty air filters. Air filters work to remove dust, debris, and other pollutants from the air circulating through the unit. Over time, these pollutants accumulate on the filter, reducing the flow of air and making the unit work harder than necessary. This can cause the air conditioner to freeze up, resulting in poor cooling performance.
To fix this, take out the old filter and replace it with a new one. Make sure to choose an air filter that is designed for your specific make and model of air conditioner.
Leaking Refrigerant
If your air conditioner is blowing hot air or not working at all, it may be due to a refrigerant leak. Refrigerant is the substance that cools the air in the air conditioning system. Leaks can occur when the unit is old or has been damaged.
To fix this problem, you must first locate the leak. Once the leak is found, call a professional HVAC technician to repair the leak and recharge the system with refrigerant.
Faulty Capacitors
If your air conditioner isn’t turning on, it could be due to a faulty capacitor. Capacitors are small components that provide the burst of energy needed to start the unit’s motor. Over time, capacitors can wear out or become damaged, causing the air conditioner not to turn on.
To fix this, locate the capacitor and inspect it for damage. If the capacitor is swollen or leaking, it needs to be replaced. You can replace the capacitor yourself, but make sure to follow the instructions in your owner’s manual carefully.
Clogged Condensate Drain Line
The condensate drain line removes the moisture that collects in the air conditioning system. Over time, this line can become clogged with dirt and debris, causing the unit to stop working or leak water.
To fix this, locate the condensate drain line and use a mixture of water and vinegar to flush out any buildup. You can also use a wet/dry vacuum to remove any debris from the line.
Dirty Evaporator Coils
The evaporator coils in your air conditioner work to remove heat from the air, making it cooler. However, when these coils become dirty, they can’t absorb heat as efficiently, causing the unit to work harder than necessary.
To fix this, locate the evaporator coils and clean them with a soft brush or cloth. You can also use a commercial coil cleaner, but make sure to follow the instructions carefully.
In conclusion, air conditioner problems can be annoying, but with a little bit of troubleshooting, you can easily fix most issues yourself. However, if you feel uncomfortable attempting any of the above repairs, it’s always best to call a professional HVAC technician to take care of the problem.
