If you’ve noticed a torn black pipe around the outside portion of your air conditioning unit, don’t worry! That’s just tubing insulation. Often referred to by the trade name “Armaflex,” this material plays an important role in keeping your A/C running smoothly. However, it’s not uncommon for this insulation to get damaged from prolonged sun exposure or from tools like weed eaters or edgers.
Why is Tubing Insulation Important?
The insulation typically covers the large refrigerant line, called the “suction line,” which carries cool, vaporized refrigerant back to the compressor in your system. This line helps to keep the compressor cool and functioning properly. If you have a heat pump, this same line transforms into a hot gas line during colder months, carrying high-pressure vapor in the opposite direction. When that happens, the insulation also prevents anyone from accidentally touching the extremely hot line. Plus, it protects nearby wires from melting.
Should You Worry About Damaged Insulation?
Here’s the good news: Torn or damaged tubing insulation outside your unit has minimal impact on your system’s performance. It’s not an emergency, and your A/C will typically keep running just fine for now. However, leaving it damaged for too long can slightly affect your compressor over time, which could mean bigger issues down the road for your air conditioner.
Quick Fixes for Homeowners
If your insulation is looking worse for wear, the fix is simple. You can ask your A/C technician to replace it during your next maintenance visit. They’ll likely have the right materials on hand to get it repaired in no time. Some professionals, like us at Kalos, even coat the lines with a UV-protective white coating to prevent future damage from sunlight. It looks better and keeps your system in better shape, too.
For now, there’s no need to stress, but it’s always worth keeping your insulation in good condition to keep your home cool efficiently and your system protected.
