On a piping hot summer day here in Hinsdale, nothing is more frustrating than to discover that your air conditioner is malfunctioning. One of the most common issues is that your air conditioner is blowing out hot air instead of the usual cool breeze you’d expect.

Below, this Hinsdale air conditioning repair company is going to discuss some of the reasons why your air conditioner could be blowing out warm air.

Thermostat Issues

An incorrect thermostat setting, or a malfunctioning thermostat, could be the reason why your air conditioner is blowing warm air. First, you’ll want to check the thermostat to make sure you have it set at the right temperature — a power surge, for example, could cause your thermostat to reset, which could change the settings. However, if the thermostat is malfunctioning (i.e., there is no change in temperature even when the thermostat setting is changed), you should call your local Hinsdale air conditioning repair company to identify the problem.

Clogged Air Filter

A clogged air filter can drastically reduce overall airflow, which is one of the most common causes of an air conditioner malfunction.

The air filter is designed to remove dust, dirt, and other contaminants before the air passes over the evaporator coils. When the filter is clogged, the evaporator coils get dirty, which can cause them to freeze. The frozen evaporator coils impede the flow of cool air, which ultimately results in warm air.

To check your air filter, you can perform a quick test by taking it out and holding it up to a light. If light can’t pass through it, it’s equally difficult for air to pass through it as well. In general, we recommend changing your air filter every one to two months.

Low Refrigerant

The refrigerant is responsible for absorbing heat from the air inside your house. If the refrigerant is leaking, then the air conditioner will not be able to absorb heat. If you notice any moisture forming around the indoor and outdoor AC units, then you most likely have a refrigerant leak. In this case, you’ll need a refrigerant change to fix the problem. Your local Hinsdale AC repair company can handle this for you.

Electrical Issues

A loss of power to the outdoor AC unit will cause the condenser to stop working. If this happens, the air conditioner won’t be able to cool the air it blows out.

Start by checking the circuit breaker and the emergency shut-off switch. If this is a recurring problem, it could be a sign of a serious electrical issue. In this case, it’s best to have a professional inspect the electrical system as soon as possible.

Disconnected or Leaky Ducts

Unfortunately, airflow problems in the ducts are not visible. If the duct has cracks or holes, or is completely disconnected, the air returning may not be able to make it back to the unit. Alternatively, the cool air may be getting trapped inside the attic, walls, or crawl space, resulting in warm air being sent to the rooms.

It is possible that a home renovation or construction project may have damaged the ductwork. Birds and wildlife can also get into the ductwork and cause damage. Regardless of the cause, if you think your ductwork might be damaged, you should contact an HVAC repair specialist in Hinsdale, Illinois for an inspection.
