My Air Conditioner is Not Blowing Cold Air

When the thermometer is skyrocketing in the greater Chicagoland area, you rely on your air conditioning system to keep you cool and comfortable. Extreme heat not only makes you feel low on energy and supremely uncomfortable, it can also pose a health risk.

If the air conditioner in your home or place of work isn’t blowing cold air, you should get to the bottom of the problem as soon as possible.

Extreme heat doesn’t just make you feel unpleasant. It can lead to dehydration and other heat-related illnesses, particularly for children up to age 4, people 65 or older, overweight individuals and patients with conditions that their doctors say could be exacerbated by excessive heat, noted a report from the Centers for Disease Control and Prevention.

In a worst-case scenario, a vulnerable person could succumb to heat stroke, where he or she cannot control body temperature (no longer able to perspire and cool down). Left untreated, the result can be disability or death.

So as you can see, maintaining cool temperatures during summer is not just to keep you comfortable but to keep you healthy too.

Here are some common reasons why an air conditioner is not blowing cold air. In some cases, you may be able to remedy the situation yourself. Otherwise, the professionally trained technicians at Ardmore are standing by to assist you and get the AC back up and running.

Thermostat Settings

The first thing you should check is the thermostat. Under normal circumstances, you would set the thermostat to turn on the air conditioning when the inside temperature reaches a certain threshold, such as 74 degrees Fahrenheit. However, if you have set the thermostat to “On” instead of “Auto,” this means the fan will run even when the system is not cooling the air.

Switch the thermostat to “Auto” and it should only blow cool air. If this doesn’t take care of the situation, more investigation is in order.

Air Filter

Your next point of inspection should be the air filter. How long has it been since you changed the disposable filter? You should always put a fresh new filter in according to the manufacturer’s instructions. If you have pets that shed a lot of hair or if there is a great deal of dust and dirt in the air inside your home, this can cause the filter to get dirty earlier than usual.

A dirty air filter can block air that needs to flow to the air handler, resulting in a weak flow of air that is not nearly as cool as you’d expect.

Replace your filter and make an entry in your calendar to remind you to swap out the next one in plenty of time.

Dirty Condenser or Evaporator

The condenser, located outside your home, may be dirty, making it unable to adequately cool your home. Inspect it and remove any twigs, dirt, dust and other debris covering it and then see if the system runs properly again. The AC’s evaporator coil inside your home can also accumulate dirt and dust, preventing it from working at normal capacity.

A qualified technician will inspect these trouble spots and perform routine maintenance and cleaning to prevent the problem from reoccurring.

Low on Refrigerant

When the system has a leak, refrigerant can escape (sometimes quite slowly so it takes a while before you notice a diminishment in performance). This is a task for an HVAC professional to take care of. He or she will repair any leaks and add refrigerant as needed to bring the system back to its normal capacity.

Improperly Sized

A knowledgeable HVAC technician will measure the building and make calculations to properly size the air conditioner. You might think that “bigger equals better,” but this is not the case in air conditioning. Equipment meant for a much larger building will tend to cycle on and off more frequently, overworking the system and generating less cold air. A professional can quickly determine if your AC setup was sized improperly.
