Try cleaning your air conditioner's filter and the coils to see if improving the airflow fixes the problem. If there is ice buildup, you'll need to run the unit with just the fan in order to melt it off. If that doesn't get the unit blowing cold air again, it could be refrigerant levels are low (see below).

No warm air delivery at all. If you turn your central heating system on and set it to the desired temperature but it doesn't deliver any air, you'll have to attempt to isolate the problem. It might be a tripped or bad breaker, an issue with the electrical wiring, or, it could be the unit itself no longer works.

Well, certain problems can prevent an air conditioner from properly cooling down your home including: A dirty air filter. A blocked condenser. A refrigerant leak.

Without enough refrigerant, your air conditioner won't be able to absorb as much heat from your home's air. That means the air blowing out of the vents will feel warmer than normal. In some cases, there may also be less air blowing out of the vents.

But Horovitz said this is more of a problem with air conditioning that's left on at night than it is with fans. If you do sleep with air conditioning on at night, Horovitz said the air shouldn't be blowing directly on you and the setting shouldn't be lower than 68 degrees Fahrenheit (20 degrees Celsius).

Here's what you need to know: air conditioning systems aren't like a car; they don't burn gas to operate. Your air conditioner is a closed loop, it cools the air by changing the refrigerant inside the copper coils from its liquid state to its gaseous state. In its liquid state, R410a and R22 are very cold.

If the air conditioner does not cool, the compressor might be defective. The compressor is a motor which compresses the refrigerant or coolant and circulates the refrigerant through the evaporator and condenser coils. If the compressor goes bad the cooling cycle does not start and the AC fails to cool.

Common solutions for: Haier Air conditioner not cooling. If the air filter is clogged, air cannot flow properly through the air conditioner. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over.

Cold air can also cause muscle contractions, and so exposure to this air at night may lead to a stiff neck in the morning. ... If you do sleep with air conditioning on at night, Horovitz said the air shouldn't be blowing directly on you and the setting shouldn't be lower than 68 degrees Fahrenheit (20 degrees Celsius).

(Fans in windows can blow cooler air into a room from outside). Fans do not cool the air, so air currents flowing over the body must be cooler than your body temperature to cool you down. When indoor air temperatures are hotter than about 95 °F: Fan use may cause your body to gain heat instead of lose it.

Problem #3: Faulty fan motor Like we mentioned before when we discussed dirty air filters, low airflow causes limited air circulation and a frozen evaporator coil—both of which mean you're not feeling cold air coming from your AC. Solution: Contact an AC expert to inspect your fan motor and the fan itself.

It could be an electrical failure in the circuit during charging, overheating vehicle, or maybe the coolant is just low. ... So, make sure that you check the compressor as it could be the reason why car AC not blowing cold air after recharge.

If your air conditioner will turn on, and your thermostat is set properly, but your system is not cooling you may have a dirty or blocked air condenser. Your first step is to check the outside unit and clean around and remove any debris or weeds that are blocking air circulation.

Lack of Airflow Weak airflow is one of the first signs that an air conditioner is on the fritz. You'll start to notice little airflow coming from the AC vents, which is a sure sign that the unit's compressor is failing or that your ductwork is clogged.

AC Fan Not Working Inside If your AC indoor fan isn't working, first check to make sure a breaker hasn't been tripped. If all is OK, check your air filter. ... If there's ice on the evaporator coil and refrigerant lines, allow the ice to melt, then check again to see if the fan is working.

If the air handler is working fine, the fan will still blow air into your space. But without the condenser unit working properly, there will be no cooling; hence, your AC blowing warm air.

Your refrigerant is low. One of the most common causes of an AC system blowing warm air is a lack of refrigerant. ... Regular shutoffs when the room temperature is correct give ice on your evaporator coil a chance to melt, so low refrigerant can lead to a cycle of warm air and icing on your evaporator coil.
