Refrigerant Fluid Lines: Common Issues to Expect


Refrigerant fluid lines are the lifeline of the air conditioning unit that keeps the function of the AC stable, allowing it to produce consistent temperatures throughout the home. The majority of the time they work perfectly, but sometimes there are issues that need to be addressed. This is especially common in older units that have served the home for a while. As the area’s experts in air conditioning repairs, we dedicated this blog post to refrigerant fluid lines. Here, we will discuss some of the most common issues you can expect when it comes to the refrigerant fluid lines in your AC unit. 


Refrigerant Fluid Leaks

Leaks are one of the most common issues you can expect with refrigerant fluid lines in an AC unit. These types of leaks can occur due to a variety of factors including poor installation, corrosion, or damage to the line. If a leak is detected, it is important to address it as soon as possible to prevent the refrigerant from escaping. 


Refrigerant fluid is very poisonous and if ingested, it can cause adverse health outcomes. The increased levels of dampness or moisture from the leaks can also contribute to mold growth. As a result, if you notice a leak coming from your AC unit, contact a Universal Air and Heat air conditioning tech to help fix the issue.




Refrigerant fluid lines can develop clogs. The problem can sometimes be explained by dirt and contamination in the lines, preventing the fluid from flowing freely and providing cooling to the air. However, if the refrigerant food lines are frozen, the accumulated ice will also prevent proper fluid flow. 


Using specific tools and chemicals, air conditioning technicians can clear out these types of clogs. We do not recommend trying to repair this issue yourself because you will need specialized training and tools to do so. Plus, most states require that refrigerant fluid is handled by a certified professional. 


Poor Insulation


Poor insulation of refrigerant fluid lines in an AC unit can cause a range of issues, including increased energy, consumption, reduced performance, and decreased efficiency. Insulation is important because it helps to maintain the temperature of the refrigerant, preventing it from escaping or condensing in the line. Poor insulation will need to be replaced or repaired to ensure that refrigerant fluid lines are properly protected.


Poor Fluid Levels


Refrigerant fluid levels must be set appropriately in order to ensure optimal comfort levels in your home. If there’s too much refrigerant fluid in the lines, your lines may end up freezing and preventing proper airflow, as we discussed above. Additionally, if there isn’t enough fluid in the refrigerant fluid lines, your air conditioning system will not have enough support to cool the home. As a result, you may end up feeling a little warmer during the summer months when you expect your AC to cool your house. If you are experiencing any of these issues, contact a Universal Air and Heat air conditioning repair tech today to have this issue investigated and resolved.


How To Prevent Issues With Refrigerant Lines


Thanks to modern technology and advancements in the HVAC industry, problems with refrigerant and fluid lines are few and far between. In fact, most of these issues can be avoided with a proper maintenance routine for your AC system. We strongly recommend a routine maintenance check at least once a year to ensure that your AC has the proper refrigerant fluid levels and that all the components are aligned appropriately to deliver the comfort levels in your home.
