The Dangers of Freon Leaks & How to Avoid Them

Evolution Maintenance

Have you ever heard of Freon leaks? Maybe you remember Freon from chemistry class a long time ago?


Well let us refresh your memory…


Freon isn’t an element, or even a naturally occurring substance. The name “Freon,” which is actually a registered trademark, is used to describe an entire class of a synthetic chemicals that are commonly used in refrigeration products (also called “refrigerants). These products that are variants of Freon are typically stable and nonflammable, but they are also toxic.


Some variation of Freon is probably in your refrigeration unit or air conditioning unit right now, so it’s important that you understand the dangers, and how to avoid them! However, since we don’t know exactly which version of Freon we are dealing with, we’re going to keep this article as broad as possible.


WHAT ARE THE DANGERS OF FREON LEAKS?

First of all, the dangers of exposure to Freon are not life-threatening so long as the exposure is minimal. Prolonged, intense exposure to Freon can have a much more detrimental impact on a person’s health.


IN GENERAL, THE DANGERS OF MILD EXPOSURE TO FREON INCLUDE THE FOLLOWING:

Irritation of the eyes & ears

Irritation of the throat & coughing

Nausea & vomiting

Headache

Frostbite or chemical burns (in the case of direct, physical contact)

Dizziness or lightheadedness

AND THE DANGERS OF CONCENTRATED OR PROLONGED EXPOSURE TO FREON INCLUDE:

Fluid or blood buildup in the lungs

Vomiting blood

Burning sensation in the esophagus

Difficulty breathing

Decrease mental capacity

Seizures

Loss of Consciousness

Cardiac Palpitations

Death (in extreme circumstances)

The demographic that is most vulnerable to the effects of Freon are individuals who suffer from heart problems. In small amounts, the effects of Freon should be relatively benign. However, more concentrated exposure to Freon can lead to severe, high-frequency, and potentially dangerous cardiac palpitations.


The direct inhalation of Freon to ‘get high’ has managed to catch on in certain circles. This is particularly risky. There have been fatalities that have occurred as a result of even the first use of Freon as a drug. Inhaling Freon can cut off the oxygen supply to your cells and lungs.


HOW TO DETECT + PREVENT FREON LEAKS

The 2 places where you are mostly likely to find Freon are your air conditioning unit and your refrigeration unit. We’ll start by listing some warning signs for leaks in your A/C unit.


SIGNS THAT YOUR A/C UNIT HAS A FREON LEAK

It’s blowing out hot air, especially during daylight hours

Frost is building up on your indoor air conditioner coil

Condensation is leaving puddles on your floor

There are visible holes or cracks in your A/C coil

In extreme cases, you might be able to hear the Freon escaping

SIGNS THAT YOUR REFRIGERATION UNIT HAS A FREON LEAK

It’s no longer cold inside

You’re hearing hissing and gurgling sounds

There are puddles underneath the refrigeration unit

There is evidence of damage in the tubing or condenser

The evaporator coils are covered in frost and/or ice

If you are noticing any of these symptoms in your air conditioning unit or your refrigeration unit, it’s time to call the professionals. This stuff can be dangerous, so don’t delay! You can make an appointment with us at Evolution Maintenance. We’re here to help!

Warmer days are coming. Make sure your commercial HVAC system is ready to perform. efficient, reliable, and cost-effective. As winter fades and temperatures begin to rise, your commercial HVAC system is about to work in a whole new way. After months of heating demand, spring brings fluctuating temperatures, higher humidity, and increased cooling needs. If your system is not properly prepared, you could face higher energy bills, reduced comfort, and unexpected breakdowns right when your business needs reliability most. Preparing your commercial HVAC system for spring is not just routine maintenance. It is a proactive strategy to protect your equipment, control operating costs, and create a comfortable environment for employees and customers. Here is how to get your system ready. 1. Schedule a Comprehensive System Inspection A professional inspection is the foundation of seasonal preparation. During winter, HVAC systems endure heavy use. Components can loosen, wear down, or accumulate debris. A spring inspection should include: Checking refrigerant levels and inspecting for leaks Testing thermostat calibration and controls Inspecting electrical connections and components Examining belts, motors, and moving parts for wear Verifying proper airflow throughout the system Identifying small issues early prevents them from turning into costly repairs during peak cooling season. 2. Replace or Clean Air Filters Air filters often become clogged during winter months due to continuous operation. Dirty filters restrict airflow, reduce efficiency, and strain your system. Replacing or cleaning filters: Improves indoor air quality Enhances system performance Reduces energy consumption Extends equipment lifespan For commercial properties, this simple step can significantly impact comfort and operating costs. 3. Clean Coils and Condenser Units Outdoor condenser units accumulate dirt, leaves, and debris throughout fall and winter. Evaporator and condenser coils can also collect buildup that reduces heat transfer efficiency. Cleaning these components allows your system to cool more effectively and prevents overheating. Clear space around outdoor units to ensure proper airflow and optimal performance. 4. Test Cooling Performance Early Do not wait for the first hot day to discover a problem. Run your cooling system in advance to ensure it is operating properly. Listen for unusual sounds, monitor temperature consistency, and verify that all zones respond correctly. Testing early gives you time to address issues before demand increases and service schedules fill up. 5. Evaluate Energy Efficiency Spring is an ideal time to review your building's energy performance. Consider: Reviewing past utility bills for unusual increases Inspecting ductwork for leaks Confirming programmable thermostats are set correctly Assessing whether older equipment may need upgrading Improving efficiency now can lower your cooling costs all summer long. 6. Check Drain Lines and Humidity Controls As humidity rises in spring, proper drainage becomes critical. Clogged condensate drain lines can lead to water damage, mold growth, and system shutdowns. Ensure drain lines are clear and humidity controls are functioning properly to maintain a healthy indoor environment. Why Spring HVAC Preparation Matters Unexpected HVAC downtime can disrupt operations, impact employee productivity, and create an uncomfortable experience for customers. Preventive maintenance protects your investment and ensures your system performs when you need it most. A well-maintained commercial HVAC system: Operates more efficiently Lasts longer Breaks down less frequently Maintains consistent indoor comfort Spring preparation is not just about maintenance.

5 Signs Your Commercial HVAC System Needs Immediate Attention Your commercial HVAC system is the heart of your business's comfort and operational efficiency. When it's working properly, you barely notice it. But when something goes wrong, it can create a costly disruption—impacting everything from employee productivity to customer satisfaction. Recognizing early signs of HVAC problems can help you avoid expensive emergency HVAC repairs or complete system replacements. Here are five warning signs you should never ignore. 1. Unusual Noises Commercial HVAC systems typically run quietly in the background. If you start hearing banging, clanging, squealing, or grinding noises, it's a clear signal that something is wrong. Possible causes: Loose parts, worn bearings, motor issues. Why it matters: Ignoring unusual sounds can lead to major component failures and higher repair costs. If your HVAC system suddenly sounds like it's struggling, it’s time to schedule an immediate inspection with a trusted commercial HVAC maintenance provider like Evolution Maintenance. 2. Inconsistent Temperatures Are some rooms freezing cold while others feel stuffy and warm? Uneven heating or cooling is more than just an inconvenience—it’s a red flag. Possible causes: Blocked vents, failing compressors, thermostat malfunctions, or ductwork problems. Why it matters: Temperature inconsistencies strain your system and drive up energy bills. Properly diagnosing and fixing these issues early prevents unnecessary energy waste and discomfort for employees and customers alike. 3. Sudden Spike in Energy Bills If your utility bills have shot up without a clear explanation, your HVAC system may be working harder than it should. Possible causes: Dirty coils, clogged filters, refrigerant leaks, or malfunctioning parts. Why it matters: High energy consumption means your system isn’t running efficiently, costing your business money month after month. Scheduling regular commercial HVAC inspections can help pinpoint inefficiencies before they become long-term financial drains. 4. Frequent Cycling If your HVAC system is constantly turning on and off (known as "short cycling"), it's struggling to maintain the desired temperature. Possible causes: Thermostat issues, refrigerant leaks, oversized equipment, or electrical malfunctions. Why it matters: Short cycling stresses your system, causing faster wear and higher repair costs. This behavior can significantly shorten the lifespan of your HVAC unit if not addressed quickly through professional HVAC servicing.\ 5. Poor Indoor Air Quality Bad smells, excessive dust, or a sudden rise in allergy symptoms among employees could point to HVAC system problems. Possible causes: Mold growth, dirty filters, clogged ducts, or stagnant moisture. Why it matters: Poor indoor air quality not only affects health but can also open your business to liability issues and customer complaints. An experienced commercial HVAC technician can assess and resolve indoor air quality problems to keep your environment safe and inviting. Don’t Wait—Protect Your Investment Delaying action when your commercial HVAC system shows warning signs can lead to higher repair costs, lost business, and even complete system failure. Being proactive is key.  At Evolution Maintenance, we specialize in rapid response and preventative care for commercial systems of all sizes.
