Troubleshooting: Air Conditioning
Trouble with your air conditioning system? We are here to help you diagnose and solve common issues that may arise. By following the steps outlined below, you can potentially fix the problem without the need for a vendor visit!
No Cold Air
If your air conditioning system is running, but no cold air is coming out, there could be a few possible causes:
Thermostat Settings
Check if the thermostat is set to "cool" and the temperature is set lower than the room temperature.
Air Filter
A clogged or dirty air filter can restrict airflow and reduce the cooling efficiency. Check the air filter and clean or replace it if necessary.
Fan Setting
Is the fan set to "auto," "on," or "off?" If the setting is "on", the fan will run constantly, even when the system isn't cooling the air. Setting the fan to "auto" can resolve the issue by turning off the blower when the system isn't actively cooling. Setting the fan to "off" will completely stop it from running.
Electrical
If the AC does not make noise or "start" when the thermostat says the air is on, check to see if any electrical breakers need to be reset. If breakers aren't tripped and the unit remains without power, check to see if there is a switch near the furnace that may control the power.
Refrigerant Leak
Low refrigerant levels can prevent the air conditioner from cooling properly. If you suspect a refrigerant leak, it is best to contact a professional technician to handle the issue.
Insufficient Airflow
If you notice that the airflow from your air conditioning system is weak or insufficient, try the following troubleshooting steps:
Dirty Air Vents
Dust and debris can accumulate in the air vents, causing blockages that restrict airflow. Check to see if the vents are free to circulate air.
Blocked Condenser Unit
The condenser unit located outside may become blocked by leaves, dirt, or other debris. Check the unit and clear any obstructions carefully.
Strange Noises
Unusual noises coming from your air conditioning system may indicate underlying issues. Here are a few common causes:
Loose or Damaged Fan Belt
A loose or damaged fan belt can produce squealing or screeching noises. Let us know if this is occurring, and we will schedule a technician.
Faulty Motor Bearings
If you hear a grinding or rattling noise, it may be due to worn-out motor bearings. Let us know if this is occurring, and we will schedule a technician.
Debris in the Unit
Debris, such as twigs or leaves, can get caught in the fan blades, causing clicking or banging noises. If possible, carefully remove any foreign objects from the unit in a safe manner. If not possible, contact us and we will schedule a vendor.
