AC Not Blowing Cold Air: 5 Reasons Why This is Happening
Does the AC blow too hot air? You don’t want to wake up when it doesn’t work properly. Not only is it painful but it can be a dangerous situation for yourself, family and pets. If it appears you have an issue immediately, please act accordingly.
Keep an eye out for when temperatures are unbearable. If you’re unsure, always call an HVAC technician. There are a few possible reasons your HVAC unit may be blocking the airflow in your home. Some things are easy and are handled immediately and others may require specialized care.
IS YOUR AC UNIT RUNNING, BUT NOT BLOWING AIR?
When your computer has started, put your hands on the air register (the vent in floors and windows provides cool air). Does air blow? If the airflow is stagnant with zero airflow, the air handler will be affected. How many times have filters ever been changed? Is there an alternative? Double check the filters in the room to determine the condition.
How Does a Central AC System Work? In order to better understand what may cause your AC to not work properly, it will help to know how it works. Your air conditioning unit uses a liquid refrigerant. This liquid passes over the indoor evaporator coils to absorb the heat inside your home. Absorbing the heat transforms this liquid into an icy gas.
The Filter Is Dirty or Clogged
Other common issues affecting the AC is the dirty filter, it’s clogged. This air filter traps hair particles and dirt in the air throughout the year. Often the full size of these can become large without a regular change. When the situation happens, the air doesn’t flow properly to the residence and you can shut off AC if your system doesn’t have enough air.
When the heating system does not work, interior temperature rises significantly. Leaving it for too much time can cause filters to fail faster. This is a potential issue in evaporation coils and condensing equipment that could potentially cause a lot of problems.
Air Conditioner Not Cooling Enough
Check all vent doors. When a single vent is closed, it can cause more problems for cooling the house because the air in the closed vents mixes in to warm air from the other. A second issue could arise from a leak on the cooling system. The older system that you install or use incorrectly is rusty or may have been incorrect in size or shape. The system is big and will run too quickly and it reduces its effectiveness. The small system in your house may not cool the home sufficiently, causing premature failure.
Check the thermostat settings, the air filter, and the condenser unit for previously mentioned problems if your heat pump system isn’t cooling. Frozen evaporator coil An evaporator coil is part of the indoor portion of the central air conditioning system. If your indoor appliance is a refrigerator, the evaporator coil is located outside the furnace in its own drawer.
Air Conditioner Won’t Blow Cold Air
If your cooling system does not produce cold temperatures, check if it is properly controlled. If there are no problems, look at the filter. Airflow is limited because it is filled with mud or dirt contaminated with debris. Because it is possible for the evaporation coils to freeze due to this leak, the airflow is clogged.
Clean the filters by rubbing the brush gently. Then rinse. Clean the filters frequently and prevent future problems. The fan motor may cause some issues. If the fan spins easily, then your electrical supply is not connected and there is leaking refrigeration fluid in your system.
If your air conditioner is not blowing air, there are several things that may be causing the problem. First, check to make sure the fan setting is set to “on” and not “auto”. If the fan setting is correct, then check to make sure all of the vents in your home are open and not blocked by furniture or curtains. If the vents are open, then check to see if the air filter needs to be replaced.
There Is a Problem With the Evaporator Coil or Condenser
These filters work very well to keep the coils clean to provide optimal performance but the coils can wear out quickly and often. Due to constant humidity, your vaporator coils are susceptible to mold and mildew. UV lighting protects you from it keeping it cool.
The coil freezes if the system contains low recirculating refrigeration. The coil issue can affect the cooling unit and requires immediate attention from an HVAC professional. Depending on how many uses, a condenser has the possibility of deteriorating.
If even one of them is closed, it can make it more difficult to cool your entire home, since the warm air from the room with the closed vent will mix with the cooled air from the others. Otherwise, you may have another problem, such as a leak in your refrigerant line.
How Does a Central AC System Work?
If you’re trying to learn how an AC system works, it’s important to learn how the AC works. Make sure your air conditioner is cooled by water. These liquids pass through evaporators to absorb heat inside your house. A reduction in energy converts these liquids into cold liquids.
A fan blows air through the refrigerant cooling coils and sends warm air into the ductwork for circulation into the house. The refrigerant gases carry the energy into the outdoor condenser where the liquid is dissolved when releasing a vapor to the outdoor environment. The cycle continues until you cool the room.
An indoor air handler unit (furnace or fan coil), an evaporator coil, air filter, thermostat, and copper tubing (refrigerant lines) that link the indoor and outdoor systems are all common components of split-system air conditioners. So, to the debate, “Why isn’t my air conditioner cooling the house?” There are a few options. But don’t be concerned. Only because your system isn’t cooling doesn’t mean you have to spend a lot of money on AC upgrades or a new system. The A/C drain is a small tube that runs from the air conditioning unit to the outside of the home.
AC Window Unit Won’t Kick On
The same goes for windows: You first need to test temperature settings in a device before checking the electrical power flowing through the unit. If none of these troubleshooting steps have resolved any issues, contact a qualified technician for AC Window Unit repairs.
If you are experiencing low or no airflow, check for frost formation on the copper lines leading to the indoor evaporator coil. Chances are if ice is forming on these lines the coil is one giant ice cube. Also, check for water on the floor around the air handler. This can be a sign that the condensate drain is clogged and may need to be cleared.
