When your air conditioner is not working during a North Carolina summer, no one is going to be happy. One of the reasons why your air conditioner may not be working could be due to the freon, or AC refrigerant level. When the AC refrigerant is not where it should be, it can lead to many problems.

Our AC repair professionals at Bowman Mechanical Services want you to know what to look for when you believe your air conditioner is not working, including why your freon level may be to blame. We’re going to explain why freon is so important as well as signs that your air conditioner needs more freon and the preventative measures you can take to keep things running smoothly.

Introduction to Air Conditioner Freon and Its Importance

What is Freon and Its Role in Air Conditioners?

Freon is what makes the air cold in your HVAC unit. Without refrigerant, your air conditioner would work more like a fan. Without freon, the blower would still push air out, but the evaporator coil wouldn’t be able to remove heat and moisture from the air.

What kind of Freon does HVAC use?

Before 2020, there were two main categories of refrigerants that HVAC systems at home use, R-22 (Freon) and R-410A (Puron). R-22 was linked to environmental damage, like ozone depletion. The use of freon was phased out in 2020.

Now, many HVAC systems use R410A. Due to the lack of chlorine, it is less harmful to the environment, while still being efficient. It offers better air quality and reliability. But many systems that used to run on R22 can’t use R410A without an upgrade or replacement.

Common Signs of Low Freon Levels in Your AC Unit

Insufficient Cooling and Temperature Fluctuations

If you notice that it is taking longer to get cool air into your home, it may be because your AC system is low on freon. An air conditioning system without enough freon, won’t work efficiently.

Weak Airflow from Vents

Warm air coming from the events can be a signal of several issues with your AC system, one being low refrigerant.

Ice Formation on the Evaporator Coil

Check the evaporator coils on your AC unit and see if there is any ice building up on the copper line. If so, you may need to add freon.

When there isn’t enough refrigerant in the unit, the evaporator coil can become colder than it should, leading to moisture on its line to freeze up.

Unusual Hissing or Bubbling Noises

If you hear unusual noises like hissing or bubbling coming from your house AC unit during the hot summer months, it may be the sound of refrigerant escaping. When you hear this sound, you’ll want to call an HVAC professional to see if your AC freon is low.

Increased Humidity Levels Indoors

When your air conditioning unit loses freon, you’ll notice your home is more humid. If you notice warm air and humidity, call a licensed HVAC technician to look at your system.

Causes of Freon Loss in Air Conditioners

Refrigerant Leak

Any wear and tear on your AC unit can cause refrigerant leaks. The rubber seals on the service valve around the valve stem can wear out and leak over time. The outside sensor can also rust. In some cases, an HVAC contractor can fix the problem easily. In other cases, major repairs may be needed to remove rusted parts and fix your freon leak.

You may also experience a pinhole leak. This occurs when naturally forming acid eats away at your copper tubing. Formaldehyde forms Formic acid which forms on the coils. When it does build up on the tubes i it can lead to pinhole leaks in the copper tubes.

Faulty AC Unit Components

The rubber seals on the valve stem on central AC units can wear out over time and cause leaks. The outdoor components can also accumulate rust, leading to leaks.

How to Diagnose Low Freon Levels in Your AC Unit

Performing a Visual Inspection for Leaks

While HVAC technicians can look inside parts for leaks, you can also look around your central air conditioning unit to see if you see any leaking refrigerant. Puddling or wet spots can be an indication that you need to call a professional.

Monitoring Cooling Performance and Airflow

If you notice your vents are blowing warm air despite having the air conditioner at a reasonable temperature, there may be a malfunction with your unit. If there is cold air coming out, but the airflow is low, that can also be an indication that you need to call HVAC professionals.

Seeking Professional Assistance

When your air conditioner system just isn’t running like it used to, it’s best to call a licensed HVAC professional. They can diagnose whether you have old or new air conditioning units.

Preventive Measures and Maintenance Tips for Air Conditioners

How Does an Air Conditioner Work?

An air conditioner works by utilizing the refrigeration cycle, which involves four main components: the evaporator coil, compressor, condenser coil, and expansion valve. 

The evaporator coil absorbs heat from indoor air, the compressor raises the temperature and pressure of the refrigerant gas, the condenser coil releases heat to the outdoor air, and the expansion valve regulates the flow of refrigerant. This cycle allows for the transfer of heat from inside to outside, cooling the indoor air and creating a comfortable environment.

Role of Refrigerant in the Cooling Process

The refrigerant plays a vital role in the cooling process of an air conditioner, and AC freon is crucial for its optimal performance. 

Heat Absorption and Release

Refrigerant is a chemical compound responsible for absorbing heat from the indoor air and releasing it outdoors. During the cooling process, the refrigerant transitions between different states (gas and liquid) to facilitate heat exchange.

Evaporator Coil

Inside the indoor unit, the refrigerant flows through the evaporator coil. As warm indoor air passes over the coil, the refrigerant absorbs the heat from the air, causing it to evaporate and turn into a gas. This absorption of heat cools the air that is then circulated back into the living space.

Compressor

The compressor compresses the refrigerant gas, significantly raising its temperature and pressure. This process increases the energy level of the refrigerant, preparing it for the next phase of the cooling cycle.

Condenser Coil

The high-pressure, high-temperature refrigerant gas from the compressor moves to the condenser coil in the outdoor unit. As the gas flows through the coil, it releases heat to the outdoor air, causing the refrigerant to condense back into a liquid state. This heat release completes the cooling cycle.

Importance of AC Freon

AC freon is a specific type of refrigerant designed for air conditioning systems. It provides efficient heat transfer properties and is crucial for optimal AC performance. The right amount and type of AC Freon are necessary to maintain the cooling capacity and efficiency of the system.

Understanding AC Recharge

Over time, AC freon may deplete or leak, affecting the cooling efficiency of the air conditioner. Regular system maintenance, including AC recharge, as a form of HVAC tune-up service, ensures that the refrigerant levels are adequate and the system operates optimally. 

Signs That Indicate the Need for an AC Recharge

Let’s explore some of the common signs that indicate your AC unit is in need of maintenance services for a recharge.

Insufficient Cooling

If you notice that your AC isn’t providing the same level of cooling as before or if it takes longer to reach the desired temperature, it may indicate a refrigerant deficiency. Insufficient refrigerant levels can hinder the system’s ability to absorb and release heat, resulting in reduced cooling capacity.

Longer Cooling Cycles

If your air conditioner runs for extended periods to achieve the desired temperature, it could be due to low refrigerant levels. Insufficient refrigerant restricts the system’s efficiency, causing it to work harder and longer to cool the space. 

Warm Air From Vents

When an AC is blowing warm air from its vents instead of the expected cool air, it could be an indication of low refrigerant levels. Insufficient refrigerant limits the cooling capacity of the system, leading to the circulation of warm air. 

Exploring AC Freon for Home Use

Understanding the basics of AC freon and its significance in residential use is important for homeowners to ensure optimal performance and efficiency of their air conditioners.

To diagnose the issue with your AC unit, it is recommended to check the air filter and ensure it is clean and not obstructed. If the air filter is not the issue, we recommend contacting a professional HVAC tech to diagnose and fix the problem. 

Our HVAC systems repair services include a range of tests and inspections to determine the cause of the issue and recommend the necessary repairs. In some cases, the issue may require the replacement of components, while in others, simple cleaning and maintenance may be all that is needed to restore the cooling power of your air conditioning system.

Reasons Your Air Conditioner Might Not Be Blowing Cold Air

If your air conditioner is not blowing cold air, there could be several reasons why. Let’s take a closer look at some of the common causes of an AC system failing to blow cool air. 

Dirty Air Filter

A dirty air filter can restrict airflow, reducing the amount of air that is able to pass through the filter and circulate throughout the system. This can cause the evaporator coil to freeze and prevent the system from effectively cooling the air. Not to mention, a dirty air filter can contribute to poor indoor air quality and health issues. To fix this issue, simply replace or clean the air filter.

Frozen Evaporator Coil

If the evaporator coil becomes frozen, it can prevent the central air conditioning system from effectively absorbing and releasing heat, resulting in reduced cooling power. This issue can be caused by a dirty air filter, low refrigerant levels, or restricted airflow. To fix this issue, you will need to identify and address the root cause of the freezing.

Low Refrigerant

Low refrigerant levels can prevent the air conditioning system from effectively absorbing and releasing heat, resulting in reduced cooling power. This issue is often caused by leaks in the refrigerant line. To fix this issue, a cooling system contractor will need to identify and repair the leaks and recharge the refrigerant.

Blocked Condenser Unit

A blocked condenser unit can prevent the air conditioning system from effectively releasing heat, resulting in reduced cooling power. This issue can be caused by debris, leaves, or other materials that block the airflow around the condenser unit. To fix this issue, simply clean the condenser unit or remove any obstructions.

Faulty Compressor

A faulty compressor can prevent the central air conditioning system from properly circulating refrigerant, resulting in reduced cooling power. This issue may require the replacement of the compressor or other components of the system. 

Ductwork Issues

Leaking ductwork or improperly installed ductwork can result in the loss of cool air before it reaches your indoor spaces, resulting in reduced cooling power. This issue may require duct sealing or the replacement of damaged or improperly installed ductwork.

Bad Fan Motor

If the fan motor is not functioning correctly, it may not be able to circulate cool air throughout your indoor spaces, resulting in reduced cooling power or a system that has no cold air blowing from it. This issue may require the replacement of the fan motor or other components of the central air conditioner unit.

Thermostat Issues

If the thermostat is not functioning correctly, it may not be sending the proper signals to the air conditioning system to turn on or off, resulting in reduced cooling power. If the temperature does not match your thermostat, the resolution may be to replace the thermostat or other components of the system.

Electrical Issues

Electrical issues such as faulty wiring or a tripped circuit breaker can prevent the air conditioning system from turning on or functioning correctly, resulting in reduced cooling power. This issue may require the repair or replacement of electrical components of the system.

How Do You Fix an AC That Won’t Get Cold?

If you want to try your hand at a DIY intervention for fixing your AC unit prior to calling a professional, there are a few steps you can take to fix the issue: 

1. Check the thermostat: Make sure the thermostat is set to the desired temperature and is in cooling mode. Sometimes the issue can be as simple as a thermostat setting.
2. Clean or replace the air filter: A dirty or clogged air filter can restrict airflow and reduce the efficiency of your AC. Clean or replace the air filter and see if that solves the problem.
3. Check the condenser coils: The condenser coils can become dirty or clogged over time, which can reduce the efficiency of your AC. Use a soft brush to clean the coils and see if that improves the cooling.
4. Check the refrigerant levels: Low refrigerant levels can cause your AC to blow warm air. If you suspect that your refrigerant levels are low, contact a professional HVAC technician to check and refill the refrigerant.
5. Check for leaks: A refrigerant leak can cause your AC to blow warm air. If you suspect that you have a refrigerant leak, contact a Raleigh HVAC company to fix the issue.
6. Check the ductwork: Leaky or poorly insulated ductwork can cause your AC to blow warm air. Inspect the air ducts for leaks and make sure it’s properly insulated.

If none of these steps resolve the issue, it’s best to contact Bowman Mechanical Services to diagnose and fix the problem with your AC unit.
