As a homeowner, you rely on your HVAC system to maintain a comfortable indoor environment all year long. When your system isn't working properly, it can cause a number of problems, including an increase in energy bills, decreased indoor air quality, and even system failure. One of the most common problems homeowners have with their HVAC system is a refrigerant leak.
Here's what you need to know about HVAC refrigerant leaks, including the warning signs, potential causes, and repair options:
What Is Refrigerant and How Does It Work in Your HVAC System?
Refrigerant is a chemical that is used in air conditioning and refrigeration systems to cool and dehumidify indoor air. It circulates through a closed system of pipes, absorbing heat from the indoor air and transferring it outside. The process is repeated until the indoor air temperature is comfortable.
Refrigerant Leak Warning Signs
One of the most common signs of a refrigerant leak is a hissing sound coming from your HVAC unit. This is caused by a tiny leaking hole in a refrigerant line.
You may also notice that your system is running longer than usual but not producing enough cool air. Other warning signs include increased energy bills and ice buildup on the refrigerant lines or evaporator coils. If you notice any of these things, you should immediately call a professional HVAC technician to check your system for a refrigerant leak.
Potential Sources of Refrigerant Leaks
Refrigerant leaks can occur for a variety of reasons, including:
- Normal wear and tear on the system over time
- Corrosion of the refrigerant lines or evaporator coils
- Physical damage to the refrigerant lines, such as from a fallen tree branch
- Poor installation or maintenance practices
It's important to note that refrigerant leaks are not a normal part of HVAC system operation and should always be addressed by a professional HVAC contractor.
Repair Options for Refrigerant Leaks
Finally, if you suspect a refrigerant leak, it's important to call a professional HVAC contractor immediately. The longer you wait, the more damage your system can sustain and the higher your repair costs will be.
The first step in repairing a refrigerant leak is to locate and fix the leak source. Once the leak has been fixed, your HVAC technician will put the right amount of refrigerant back into your system. Your contractor will also check your system to ensure there aren't any other problems causing the leak and fix anything that needs fixing.
