Nothing is more frustrating than feeling warm air blowing from your vents when you need to cool down in Jacksonville. When your air conditioning blows hot air, there could be several causes. This blog will cover some common causes and solutions to help you get your system running as quickly as possible.
Thermostat
Fortunately, a common source of warm air blowing is a thermostat setting issue. Since it is a step that people often overlook, start by checking your thermostat. Make sure the device is set for cooling. It may have been turned to a heat or fan-only setting. In some cases, the thermostat may have another problem that causes it to malfunction. You can try changing the batteries or checking the owner’s manual before you call a professional.
Clogged Air Filter
An air filter catches a variety of debris and prevents it from entering your home. As time passes, it can become clogged enough to restrict airflow. This makes your air conditioner work harder and overheat, which can cause warm air to blow. Clogged filters can also increase your energy bills. Check your air filter to see if it needs to be changed. Professionals recommend changing it at least every few months. You may need to change it more often in some cases. This depends on your unit and how often you use it.
Electrical Problems
Tripped breakers and blown fuses can cause the unit to function incorrectly. Also, wiring problems with the wires connecting the unit and the thermostat can lead to improper functioning. Check for blown fuses or tripped breakers. If you suspect wiring problems, call a professional.
Insufficient Refrigerant
The refrigerant helps move heat from inside the house to the outdoors. If the refrigerant is low, your system will not cool your home properly. There may be a leak in the system that is causing this problem. Leaks can happen in the condenser coil, the refrigerant lines, or somewhere else. Do not try to deal with refrigerant issues on your own. Since it is hazardous, handling it requires the right training. If you suspect a leak, call HVAC professionals who can find and fix leak-related problems. They can also recharge the system if needed.
Condenser Coil Debris
Condenser coils release heat that they absorb. Grass, dirt, and debris can stick to them and make them struggle to work. This can cause the air conditioner to blow warm air. Also, it can cause the unit to break down sooner. Call a professional to clean your unit and inspect it.
Frozen Evaporator Coils
Evaporator coils absorb heat. When they get too cold, they freeze and cause problems. They may freeze because of a dirty filter, a fan issue, or low refrigerant. If you suspect frozen coils, turn off your unit to let it thaw. Check the air filter and the vents for obstructions. After it has thawed, turn on the unit. If this does not fix the problem, call a professional.
Compressor Issues
The compressor transmits refrigerant between the outdoor and indoor components of the air conditioning system. When this component fails, the system cannot work properly and will blow warm air. Compressors can also overheat because of strain or dirty coils. For any compressor issue, call a professional to help.
How To Prevent Air Conditioner Problems
Maintenance is the key to preventing most problems. Be sure to keep up with regular inspections and servicing from a professional. Your air conditioning system should be inspected and serviced at least once every year. Professionals can check your coolant level, look for leaks, and ensure that your unit is charged. With routine maintenance, you can find small issues before they turn into problems that lead to breakdowns. Change your air filter regularly as well. Keep the outdoor unit as clean as possible, and clear away debris from around it to promote better airflow.
