7 of the Most Common Air Conditioner Problems
Published on Apr 3, 2020 in Air Conditioners
As warmer weather approaches, it’s time to start thinking about making the switch from heat to air conditioning. Make sure your unit works ahead of time.
Common air conditioner problems can leave you stuck in the heat on the hottest days of summer if you don’t. Keep reading to learn 7 common AC problems that are anything but cool!
1. Refrigerant Issues
Air conditioners use freon as a refrigerant to absorb the heat and humidity from the room air. As it does, it turns from a high-pressure gas to a low-pressure liquid and then reverts once it cools again.
As air conditioners age, the metal can erode, leading to a freon leak, so the unit will not cool the air effectively. Uncontrolled leakage of freon can also lead to refrigerant poisoning if not taken care of promptly.
2. Broken Blower
Common air conditioner problems can also come from a broken fan. Your unit uses two of them.
One fan blows air onto the evaporator coil to cool it. The other blows the air onto the outdoor condenser to release the heat outside.
If one fan breaks, you may notice your air conditioner is working but not cooling. Dirt, broken belts, insufficient lubrication, and motor trouble can all lead to poor airflow. Call for professional service before it turns into a larger problem.
3. Duct Leaks
Inside your walls, ducts transport the cold air from your air conditioning unit to the rooms. Rodents or other issues can sometimes put holes in the ducts.
This causes the cooled air to seep into the walls instead of making its way to the rest of the house. While your house feels warmer, you will see higher energy bills, as this causes the unit to work harder in order to reach the temp you set the thermostat to.
4. Faulty Thermostat
Sometimes, thermostat problems can be a simple self-fix. Make sure you properly set the digital settings or correctly calibrate the dial.
Also, check to see that the inside of the thermostat is level, clean, and not in direct sunlight. If you do all this and recalibrate it to no avail, you may need the thermostat replaced.
5. Drainage Clog
Some AC problems happen from clogs and not breaks. The system contains a drain to dispose of the moisture your AC removes from the air.
If the line or drain gets blocked with dirt or debris, the moisture can damage the air conditioning system. Call for HVAC repair quickly, as the moisture can also damage your walls and cause dangerous mold to grow inside of them.
6. Corroded Coils
Your AC system contains evaporator and condenser coils that can corrode over time. They need HVAC service every few years to keep them working properly.
7. Dead Compressor
The compressor runs the show by pushing energy through the coils and operating the air exchange. Letting other issues go can lead to a broken compressor. Unfortunately, this is the most expensive repair and often calls for a new air conditioner.
