Home HVAC systems are essential for maintaining a comfortable indoor environment, especially during hot summer months. However, one common issue that homeowners face is refrigerant leaks. Home HVAC refrigerant leaks are a common issue where the refrigerant level is too low, leading to inadequate cooling. This problem can result in higher energy bills, reduced comfort, and even damage to your HVAC system. In this article, we will explore the causes, symptoms, and solutions for refrigerant leaks in home HVAC systems.

Common Cause of Refrigerant Leaks

Aging Equipment

Over time, HVAC systems can develop leaks due to wear and tear. Older units are more prone to refrigerant leaks as their components deteriorate. Keep that in mind as your system puts on those years of use.

Poor Installation

Improper installation can lead to refrigerant leaks. This can occur if the HVAC system is not properly sealed or if the refrigerant lines are damaged during installation. Even if the installation happened a few years back, it all depends on the size of the leak and how quickly it expels.


Corrosion of the refrigerant lines or coils can cause leaks. This is often due to exposure to moisture and other environmental factors. With weather conditions, as they are in Bountiful, this could be a big contributing factor to a leak.

Physical Damage

Physical damage to the HVAC system, such as punctures or fractures in the refrigerant lines, can result in leaks. This can happen during maintenance or from external factors like construction work.

Symptoms of Home HVAC Refrigerant Leaks

Inadequate Cooling

One of the most obvious signs of a refrigerant leak is inadequate cooling. If your HVAC system is not cooling your home as effectively as it used to, it could be due to a refrigerant leak.

Higher Energy Bills

A refrigerant leak can cause your HVAC system to work harder to maintain the desired temperature in the home, leading to higher energy consumption and increasing your utility bills.

Ice Formation

Ice forming on the evaporator coils is another sign of a refrigerant leak. This occurs because low refrigerant levels cause the coils to become too cold, leading to ice buildup.

Hissing or Bubbling Sounds

If you hear hissing or bubbling sounds coming from your HVAC system, it could indicate a refrigerant leak. These sounds are typically caused by the refrigerant escaping from the system.

Addressing Home HVAC Refrigerant Leaks

We at CMB HVAC come over to be able to pinpoint if it truly is a leak and we take the following steps:

Professional Inspection

If you suspect a refrigerant leak, it’s essential to have our professional HVAC technician inspect your system. They have the tools and expertise to accurately diagnose and repair the leak.

Repairing Leaks

Once a leak is identified, we discuss with you the homeowner what needs to be done and the options for the repair. Once we get the plan of action, the technician will repair it. This may involve sealing the leak, replacing damaged components, or installing new refrigerant lines.

Recharging Refrigerant

After repairing the leak, our expert technician will recharge your HVAC system with the appropriate amount of refrigerant. This ensures that your system operates efficiently and effectively.

Regular Maintenance Plan

To prevent future refrigerant leaks, schedule regular maintenance for your HVAC system. Routine inspections and maintenance can identify potential issues before they become major problems.

In Summary

Home HVAC refrigerant leaks are a common issue where the refrigerant level is too low, leading to inadequate cooling. Understanding the causes, symptoms, and solutions for refrigerant leaks can help you maintain a comfortable and efficient home environment. By addressing leaks promptly and scheduling regular maintenance, you can prevent costly repairs and ensure your HVAC system operates smoothly for years to come.
