HVAC Leak Prevention Strategies

Your HVAC system uses refrigerant to keep your living space at the desired temperature. Unfortunately, HVAC units can develop refrigerant leaks. Whilst your unit might function for a while with low refrigerant, it will not last for long. Ultimately, your HVAC system will fail, necessitating costly repairs or untimely HVAC replacement.


In this article, we’ll explore the signs of a refrigerant leak and what you can do about it.


How to Detect HVAC Unit Leaks

Since refrigerant is an invisible gas, it can be challenging to detect a leak. But if you remain vigilant, your system will give off signs to indicate there’s a problem. Some of these signs include:

  • Inadequate cooling—If your AC system suddenly stops working as it used to, you could have a refrigerant leak. Although there are other possible causes for the change, low refrigerant could be to blame.
  • Excess humidity—A fully functional AC system should dehumidify the air inside your home within 15 minutes of running. If your home feels humid, the refrigerant might be the culprit.
  • Long cycles—If your air conditioner seems to run much longer than usual, low refrigerant could cause the problem. Since there’s not enough refrigerant to release warm air, your AC system will not be able to meet your cooling needs. As a result, it will have to work longer and harder to cool your house.
  • High energy bills—Due to low refrigerant levels, the AC system works harder to keep the indoor temperature at your desired levels. This results in high energy bills. If you have noticed an unexplainable spike in your utility costs, the culprit could be a refrigerant leak.
  • Hissing or bubbling sounds—If you notice a hissing sound near your outdoor AC unit, you might need professional leak repair services. The escaping gas from the refrigerant lines makes a sound, which could be hissing or bubbling.


Why You Want to Catch an HVAC Leak Early

The old saying that a stitch in time saves nine also applies to HVAC maintenance. If you suspect or notice a refrigerant leak, take action right away. Early detection and repair can help prevent more severe damage, saving money and time. This is because you will likely be able to detect and address minor leaks before they morph into major repairs. Moreover, early leak detection and repair will help extend the productive life of your AC unit and ensure that your home remains cool and comfortable, even during the hottest summer days.


Knowing When to Call an Expert

When it comes to HVAC leaks, sometimes DIY repairs are not enough. If you have tried troubleshooting the problem but cannot determine the root cause, or if the leak continues despite your efforts, it’s best to call in the professionals. A professional can accurately diagnose the problem and make effective repairs.


Refrigerant is the lifeblood that keeps your living space cool and cozy throughout summer. However, refrigerant leaks can interrupt this comfort, reduce equipment life, increase energy bills, and lead to costly repairs. Early detection is critical to preventing major repairs associated with refrigerant leaks, so stay vigilant and proactive, especially if you live in hot climates where reliance on HVAC systems is high year round.
