Why Isn’t My Ductless System Cooling?

Posted on: August 7, 2017

Ductless cooling systems are becoming more and more common in the Phoenix area. They’re compact, cost-effective, exceptionally energy-efficient, and are one of the most reliable systems on the market! But considering all of this only makes things even more vexing when your ductless system refuses to do its job. Got a mini or multi-split system that won’t put out any cool air?

The Most Common Causes of Ductless System Failure

The good news is that there is a pretty set number of problems you could be having here. And even better, the majority of them are quite simple to handle with a few that can even be done all on your own.

Clogged Filtration Systems

Clogged and gunked up filtration systems are hands-down the leading cause of warm or hot air from a cooling system. This happens because when the filter is clogged up it restricts healthy air flow, effectively choking your system and preventing it from doing its job. This in turn leads to bigger problems, including warm or hot air, and even a complete cooling system freeze.

The fix here is typically an easy one, since it’s easy to spot even for a homeowner. If you see a dirty or clogged filter, simply replace or clean it. However if that doesn’t solve the issue or it keeps happening very frequently then you’d do best to look into ductless AC system maintenance.

Ductless System Freezing

Check in and around your system for signs of frost formation, or possibly even ice. See any? A cooling system freezes for one of three reasons:

  1. Air flow restriction, which in the case of a ductless system can only mean filter clogs since, you know, it lacks ducts.
  2. Low refrigerant levels.
  3. Operating the system when it’s cold outside, which causes huge pressure drops in the AC system. It is an oddball problem, but we’ve seen it a few times.

Low Refrigerant Levels

Refrigerant is basically what makes your whole cooling system tick. Without it the system will continue to go through its process, but the actual refrigeration that results in a cooler home won’t take place. Instead you’ll get nothing but gross, warm air!

An important thing to note is that when refrigerant is low in your system it almost always means a leak, since refrigerant doesn’t actually get used up or consumed in the refrigeration process. Unfortunately you’ll need a professional repair service to remedy your issues if this is the case.
