Why "Just Adding Freon" is a Thing of the Past: The Impact of A2L Refrigerant Changes On Homeowners For decades, when an air conditioning system wasn’t cooling effectively, homeowners would call their HVAC technician to “just add Freon.” While this quick fix was common, changes in refrigerant technology and environmental regulations have made it obsolete. With the introduction of A2L refrigerants, the industry is shifting toward more sustainable and efficient solutions. Here’s what you need to know about why "topping off" refrigerant is no longer possible. The Evolution of Refrigerants Refrigerants are essential to the cooling process in HVAC systems, but not all refrigerants are created equal. Over the years, refrigerants have evolved to address environmental concerns: R-22 (Freon): Once the industry standard, R-22 was phased out due to its ozone-depleting properties. R-410A: Introduced as a more environmentally friendly option, R-410A became the new standard but still has a high global warming potential (GWP). A2L Refrigerants: The latest generation of refrigerants, A2L options like R-32 and R-454B, offer lower GWP and improved efficiency, aligning with global efforts to reduce greenhouse gas emissions. Why "Just Adding Freon" is Impossible with A2L Systems The transition to A2L refrigerants has fundamentally changed how HVAC systems are serviced and maintained. Here’s why: System Compatibility Older systems designed for R-22 or R-410A are not compatible with A2L refrigerants. Using the wrong refrigerant can damage the system and void warranties. Onboard Leak Detection Systems New A2L systems are equipped with advanced onboard leak detection systems that make "just adding refrigerant" impossible. If a leak is detected, the system automatically locks out operation until the leak is repaired. This ensures safety, compliance with environmental regulations, and system reliability. Environmental Regulations Strict environmental laws now regulate the use and disposal of refrigerants. Simply adding refrigerant to a leaking system is no longer acceptable; leaks must be repaired to prevent harmful emissions. Safety Considerations A2L refrigerants are classified as mildly flammable. While they are safe when handled correctly, they require specialized training, tools, and safety measures during installation and servicing. What Homeowners Should Know With onboard leak detection systems that require permanent repairs before operation can resume, A2L refrigerants represent a new era of HVAC technology. This is going to be a major inconvenience to the customer whenever their new system has a manufacturer defect in a coil causing a leak. This is why it is more important than ever to use a reputable HVAC company to install and service these new systems. Larger companies usually have better purchasing power and parts sourcing - leading to quicker part replacements, which will now be required to the get these new systems working again. The days of "it only took a pound of freon, see ya next year!" are over. This now becomes "The system is leaking, unfortunately the onboard leak detector has locked the system out. We found a leak in the evaporator coil. We will see if we can get a coil for you and schedule a time to come replace it. Unfortunately we will have to leave the system off until we can get back" This is the future of our industry and is something we will have to work through together as business owners and consumers. It won't be fun, but we have no other choice. Ya never know, we may be buying portable air conditioners to get customers along until parts arrive in the future. Rest assured though, whatever comes, we will handle it.

Why HVAC Capacitors Fail: What Homeowners Need to Know If you’ve ever experienced an issue with your air conditioner or heat pump, there’s a good chance the culprit was a failed capacitor.

In HVAC systems and many other heating applications, the heat exchanger plays a vital role. It ensures that homes and businesses stay warm efficiently while keeping harmful gases safely contained. But what exactly is a heat exchanger, and what risks arise when it fails? Let’s dive into the details. What is a Heat Exchanger? A heat exchanger is a critical component in furnaces and HVAC systems, designed to transfer heat from one medium to another without mixing the two. In residential and commercial furnaces, the heat exchanger typically transfers heat from the combustion process (burning fuel) to the air that is circulated throughout the building. Here’s how it works: The furnace burns fuel (natural gas, propane, or oil) to generate heat. This heat is transferred to the metal walls of the heat exchanger. A fan blows air over the heat exchanger, warming the air without it coming into contact with the combustion gases. This separation is crucial for safety because combustion gases like carbon monoxide (CO) are harmful to human health. What Happens When a Heat Exchanger Fails? Over time, heat exchangers can develop cracks or holes due to wear, corrosion, or overheating. When this happens, the dangers are significant: 1. Carbon Monoxide Leaks One of the most severe risks of a failing heat exchanger is the leakage of carbon monoxide (CO) into the living or working space. Carbon monoxide is a colorless, odorless gas that can be deadly in high concentrations. Symptoms of CO poisoning include: Headaches Dizziness Nausea Confusion Prolonged exposure or high levels can lead to unconsciousness or death. 2. Reduced Efficiency A damaged heat exchanger cannot transfer heat effectively, leading to reduced efficiency in the heating system. This inefficiency results in higher energy bills and uneven heating in the building. 3. Increased Risk of Fire Cracks or damage in the heat exchanger can allow flames or high heat to escape into areas of the furnace not designed to withstand such conditions. This increases the risk of a furnace fire. 4. Increased Strain on the System Operating a system with a failing heat exchanger places additional strain on other components, potentially leading to further damage and the need for costly repairs or replacement. Warning Signs of a Failing Heat Exchanger It’s essential to recognize the signs of a failing heat exchanger early to mitigate risks: Soot buildup on or near the furnace. Unusual smells, particularly a strong or acrid odor. Visible cracks or corrosion on the heat exchanger (detected during professional inspection). Yellow or flickering burner flames instead of steady blue flames. Frequent tripping of carbon monoxide detectors. How to Prevent Heat Exchanger Failures Regular maintenance and inspections are the best ways to ensure your heat exchanger remains in good condition. Here’s how: Schedule annual HVAC maintenance with a licensed technician. Replace furnace filters regularly to ensure proper airflow. Avoid overheating the system by not setting the thermostat too high for extended periods. Install and maintain carbon monoxide detectors throughout your home or business. What to Do If You Suspect a Heat Exchanger Failure If you notice any warning signs or suspect your heat exchanger may be failing: Turn off your furnace immediately. Ventilate the area by opening windows and doors. Contact an HVAC professional to inspect and repair or replace the heat exchanger. Evacuate the building if carbon monoxide poisoning is suspected and seek medical attention if necessary. Final Thoughts A heat exchanger is a vital safety component in your furnace, ensuring efficient heating while keeping harmful gases like carbon monoxide out of your living or working space. When a heat exchanger fails, the risks can be severe, but regular maintenance and vigilance can prevent most issues. Protect your home or business by staying informed and proactive about your HVAC system’s health.
