3 Reasons to Replace Your Ductless Mini-Split

We often talk about the benefits of a ductless mini-split system. Their increased efficiency, reverse heating system, even the advantages of a no-ductwork-needed installation. However, a well-informed consumer should also be aware of the common problems that come from ductless mini-splits, and remember to contact the professionals for air conditioning repair in Indianola, IA.

They actually aren’t as bad as you’d imagine, and these are problems that are easily mitigated with our Priority Maintenance Plan and just some yearly inspections. As far as air conditioners come, every system will have its problems. After all, they are machines that require maintenance, upgrades, and replacements as much as any other machine. We still recommend ductless AC units for many homes, because they provide great air conditioning when their problems are resolved.

So, let’s get down to business. What are the problems with a ductless mini-split?

Water Leaks

Each mini-split air conditioner is connected to a power line, a refrigerant line, and a condensate line. The refrigerant and condensate lines connect to the central cabinet outside, where it disperses the warm air away from your home. The condensate line removes the moisture from the air, reducing the humidity of your home, as well as dispersing the moisture outside as well.

However, this condensate can leak water inside your home. You’ll definitely notice when this starts to happen, as you’ll see the water drip behind the air handler on the wall- which eventually will lead to your air handler falling to the ground. This is because the wall material that holds the air handler there will weaken as it gets wet.

Broken Air Handlers

This is somewhat of a problem as well as an advantage to ductless mini-splits. Since your ductless system can have up to four independently working air handlers in different parts of your home, they’re bound to have more malfunctions than one single air conditioner unit. So you might encounter more air handler problems just because there are so many of them.

Though, this is not that bad of a problem, particularly because if one air handler malfunctions, the others will still work perfectly fine. You can move to another area of your home that is still being cooled effectively and, voila! The problem is temporarily solved until a technician can repair your broken air handler.

Leaking Refrigerant

This is basically a problem that can occur with all heat pump systems that rely on refrigerant. It’s just more probable in a ductless mini-split because there are more refrigerant lines. Refrigerant must be kept under high pressure in the lines and is integral to the cooling process. Once your system starts leaking refrigerant, you’ll notice some signs, like a loss in heating or cooling power, or perhaps icing over the coils in the air handler. A refrigerant leak needs to be repaired as soon as possible.

Well, there you have it. Honestly, these problems are not anything to keep you up at night. They’re easily addressed, repaired, or replaced with a thorough maintenance program.
