Air Conditioner Blows Too Cold

Ever walked into a room after an exhausting day, only to be hit by an icy blast from your air conditioner? If so, you are not alone! Many people experience the problem of their AC blowing too cold. 

Most tend to ignore it as just something that is their imagination, but you would be surprised to know that there are actual reasons why this happens.

While there are, of course, simple things like your AC being too big for your room or non-uniform distribution of air in the place, some of the reasons are more disturbing.

When it happens because of a faulty thermostat or too high refrigerant levels, you should act on the issue and resolve it. 

In this article, I’ll dive deep into reasons why your air conditioner may be blowing too cold and what you can do about it.

Air Conditioner Blows Too Cold

Faulty Thermostat

The thermostat in your AC is responsible for regulating the temperature. 

A malfunctioning thermostat can cause the cooling system to produce extreme temperatures resulting in colder airflow. 

This causes an increased strain on your system and consumes more power leading to higher energy bills. 

Typical thermostat issues with modern digital systems include dead batteries, loose wires, or a misconfigured setting. 

If you suspect your AC issue is related to the thermostat, it is best to contact a professional HVAC technician. He’ll have the knowledge and tools needed to accurately diagnose and repair the problem. 

Don’t ignore this issue, as it can have significant consequences like long-term damage, high energy bills, and decreased efficiency overall.

The Flow of Air is Not Uniform

One common reason your AC blows too cold is due to the flow of air being irregular within the room. 

When the airflow coming from the AC unit is strong and concentrated in one particular area, it can lead to uneven cooling. 

It can also cause certain parts of your living space to become overly chilly while others remain uncomfortably warm. 

This may occur if there are blockages obstructing the airflow, such as furniture or curtains, or if your ducts are improperly sized or installed. 

To solve this problem, you can adjust your vents or install additional ones in strategic locations to ensure that air is distributed evenly. 

It’s also essential to regularly check and clean your filters to maintain proper airflow and keep your AC running efficiently.

Faulty Chilled Water Valve

A faulty chilled water valve in an air conditioning system can have serious consequences on the overall functioning of the unit. 

Coolant is pumped through a valve to cool down the air. When it does not function properly, it can lead to a variety of problems like inconsistent cooling, reduced efficiency, or even complete system failure. 

A professional technician must diagnose the issue by evaluating the valve’s electrical connections and inspecting for any physical damages. 

Replacing a faulty chilled water valve requires significant technical expertise, specific tools, and equipment. This will ensure other components of the unit are not affected during the process. 

It is important that maintenance schedules are followed to prevent future issues with this critical component and preserve optimal performance levels in AC systems.

Your AC is Too Big For the Room

An oversized AC unit can cool a room faster than necessary. This results in an uneven distribution of air throughout the space. 

It can lead to excessive humidity levels, which can make the room feel colder than it is. 

Additionally, running an AC unit that is too large for a room can cause higher energy bills and put unnecessary strain on the system. 

To avoid these issues, it is essential to have a professional HVAC technician evaluate your home’s cooling needs. 

He can also recommend the appropriate size of AC unit that will efficiently and effectively cool your space without wasting energy or causing discomfort. 

Proper sizing ensures optimal performance and longevity of your air conditioning system while maintaining comfortable temperatures throughout your home.

Thermostat in the Wrong Place

Placement can greatly affect an HVAC system’s efficiency and performance. 

If the thermostat is mounted on outer walls or next to windows that receive direct sunlight, it may read a warmer temperature than the actual ambient temperature in the room. 

This can cause it to register a false reading and force the unit to continue cooling even when it has achieved the desired temperature. 

As a result, this can waste energy and reduce comfort levels in other areas of your home. 

To avoid this issue, ensure your thermostat is mounted in an interior room away from direct sunlight, drafts, and heat sources like appliances or lighting fixtures. 

No Return Air/ Poor Return Air

The air conditioning system works by drawing in air from your space through ducts and cooling it before redistributing it into your home or office. 

However, if there is not enough return air, the system will have difficulty reaching its target temperature and may run excessively to compensate, leading to over-cooling. 

Poor return air quality can also cause issues as dust or dirt clogs up the filters, reducing airflow and causing a decrease in cooling efficiency. 

In the worst-case scenario, this can even result in burnt-out compressor motors. 

Therefore, it is important to ensure air returns are appropriately sized for your system and regularly cleaned or replaced with fresh filters. 

This way, you can keep the environment comfortable while extending the life of your AC unit.

Wrap Up 

In conclusion, it is always frustrating when your AC blows too cold. But before you start worrying about possible issues with your cooling system, ensure to check the thermostat settings for correctness. 

Proper sizing of the AC unit and regular cleaning of air filters can also help prevent over-cooling and ensure your system runs efficiently while keeping you comfortable.

Regular maintenance from a licensed professional can also help prevent issues like this from happening in the future.
