Keep Your AC Line Sets from Freezing

How to Keep Your AC Line Sets from Freezing During Winter. If you're a technician working on air conditioning systems, then you know that one of the biggest concerns during winter is preventing line sets from freezing. For those unfamiliar with line sets, they are copper pipes that transfer refrigerant between an outdoor unit and an indoor unit. When these pipes freeze, it can cause a lot of problems and put the system at risk of malfunctioning or even breaking down completely. Fortunately, there are a few ways to keep your line sets safe during winter weather. Let’s take a look at these strategies now.

 

Insulation Basics

The most important way to prevent your line sets from freezing is by properly insulating them. Insulating line sets helps to protect them from cold temperatures outside and drafts inside the building as well. Most manufacturers recommend using high-quality insulation designed specifically for use on air conditioners. Inaba Denko America Manufactures a lineset that in not only pre insulated it is also pre-paired made especially for mini-split hvac systems. Additionally, any gaps between sections should be filled with foam or caulking to prevent drafts from coming through the pipe.

 

Lineset Cover Protection

Lineset cover protection adds extra protection. Covers are constructed from a high-grade PVC for UV resistance and flame retardancy to protect line sets from weather damage, vandalism and pests. Inaba Denko America manufactures a premium lineset cover called Slimduct SD. Already recognized in the industry as the premium go to line set cover. Slimduct SD has a gloss finish and comes in four colors to maintain aesthetics of any residential or commercial building.

Check for Leaks

Another important factor in keeping your AC line sets safe is making sure that there are no leaks in the system before winter weather arrives. Leaks can allow cold air into the system, which can cause the refrigerant to freeze and create costly damage down the road. Make sure you check for leaks both inside and outside of the building when performing maintenance on an AC system so that you can catch them before they become a problem in colder temperatures.

Check Thermostat Settings

It’s also important to check your thermostat settings as winter thrives. If you have an electronic thermostat, you should make sure that it is set appropriately for heating mode rather than cooling mode during winter months. If it’s set in cooling mode, then your AC system will try to run regardless of whether it's cold outside or not—which can cause your liquid lines to freeze if the temperature drops too low.

Ensure Proper Airflow

Finally, it's important that you make sure your AC system has adequate airflow throughout its components so that it doesn't become susceptible to freezing during cold weather. Keeping air filters clean and ensuring ducts are not blocked off will help ensure proper airflow and reduce the chances of your line sets becoming frozen over time. Additionally, if you have a heat pump installed on your property, make sure it isn't running below 35 degrees Fahrenheit when outside temperatures drop significantly; otherwise, this could lead to your AC system becoming clogged with ice which could then cause problems down the road.

Conclusion:

Keeping your AC Line sets from freezing during winter will ensure maximum efficiency and prolong the life of the whole system. Keeping your AC lines safe during winter weather is an important part of being a technician who works on HVAC systems. The best way to do this is by using High-Quality pre-insulated line sets like Paircoil from Inaba Denko America, and protecting them with Slimduct SD Lineset Cover guards. Also be sure to check for leaks both inside and outside of buildings. Following these strategies will help keep your AC line sets safe during winter and all types of weather!
