When you invested in a ductless mini split system, you did so with the intention that every single unit would work. You may be able to get away with a single unit breaking down. It’s tempting to put off fixing it if your home is still comfortable, but you don’t want to. If there is a problem affecting one of your ductless units, there’s a good chance that the same problem could also impact your other units.
And what about if only one of your mini split heads is cooling, and the others are not? That’s an even bigger problem that you definitely can’t ignore. If you have a mini split with one head not cooling, you want to give us a call right away. Allowing the problem to fester could lead to a more expensive repair. Keep reading to learn more about why only one of your mini split heads are cooling while the others aren’t.
Remote Batteries
When you push a button on the remote for your mini split unit, you expect something to happen. When it doesn’t, you can panic. We get it, because we see it all the time. But you want to take a deep breath, take a step back, and consider that your remote control may actually be the problem. Try changing the batteries on your remote and then turn on your mini split unit again. If that doesn’t work, then there may be a problem with your actual unit after all.
Blower Fan
Each one of your mini split units has a blower fan and a refrigerant coil. Of course, these are smaller than what you would find on a traditional HVAC unit, but they are essentially the same. It’s possible that your blower fan motor can burn out or experience an electrical problem. Don’t try to tinker with it yourself. You need a certified professional to fix it. Unfortunately, replacing a blower fan can be very expensive, so sometimes it makes more sense to replace the individual room unit instead of the part itself. Either way, our team can talk you through your options and help you make the best decision.
Conduits
Even though each room has its own miniature heating and cooling system, each unit does still connect to your primary outdoor unit. These connections pass through a set of conduits that are behind your walls in each room. These conduits include refrigerant lines, power lines, and condensate drains. It’s possible for any one of these lines to sustain damage that impacts how your mini unit heats or cools the air. Sometimes the repair is as simple as replacing or repairing one of these lines.
Frozen Coils
The coils in your individual mini split units may be small, but they can face the exact same problems that a larger HVAC system does. One of these problems is freezing. If your system loses refrigerant due to a leak or has too much dust built up around the coils, they can freeze. if you check inside of your unit and notice a frozen coil, don’t try to remove the ice yourself. The units are very delicate and can take on damage very easily. Instead, leave the repair up to our team of professionals.
Keep in mind that it is very unusual to experience problems with multiple mini split units at one time. If only one of your units is actually cooling, the problem is probably with your outdoor unit. Either way, we can take a look at your system, both indoors and outdoors, and offer a solution.
