When space is an issue, mini-split systems come to the rescue. They are compact, efficient, and work noiselessly, all the while making indoors a comfortable haven. Nonetheless, like every other machine that works for long hours, these, too, have the tendency to throw a tantrum from time to time. If you succeed in soothing it with a timely maintenance routine from a professional HVAC technician, you don’t have to worry much about expensive repairs and disruption of your comfort. Today, we shall discuss the seven most common mini-split troubles and how you can fix them.
1. Water Dripping – Dripping water is a common problem amongst all HVAC systems. It generally happens when the condensate line or the drain line has an obstruction inside, preventing the collected moisture from draining or flowing outside. As soon as you get rid of the clogging, the problem will end. It is better to resolve this issue as soon as you notice it before the spilled water can cause an accident.
How To Fix – Using your wet and dry vacuum cleaner, suck out the blockage inside the drain line. Once the obstruction is removed, reattach the drainpipe securely, and that’s all there is to it.
2. Strange Sounds -As we mentioned right in the beginning, these systems are quiet and make almost no sound. Therefore, when you do hear something strange, don’t ignore it.
1. Sounds like clanking, banging, and rattling are produced if some component has come loose.
2. Screeching and whining sounds originate from the rubbing of moving parts without any layer to reduce friction.
3. Popping and clicking sounds arise due to the expansion and contraction of the plastic housing.
4. When the mini-split system makes the switch to defrost mode to prevent icing up, it produces a crackling, gurgling, or whooshing noise.
How To Fix – The only way to ensure that your mini-split system does not make odd noises is by following a routine annual maintenance schedule. Despite that, if the unit still makes loud or distracting sounds, call your HVAC tech for troubleshooting.
3. Not Cooling – Refrigerant is the most crucial element of the cooling process. It is what is directly responsible for lowering the temperature of the circulating air. If there is a refrigerant leak, the AC will no longer lower the temperature of the air sufficiently. As a result, the occupants of the home may feel as if there is no to minimal cooling.
How To Fix – Since you cannot measure the refrigerant level or detect the source of its leak and fix it, it is best to call your HVAC contractor. The visiting technician will first patch up the leaks and, post that, top the refrigerant to the requisite level.
4. Not Heating – You want to heat; instead, the mini-split system is blowing cold air and making you and your family miserable. Quite a few times, it has been noticed that the thermostat program was incorrect. Instead of setting it to “Heat,” it is still kept on “Cool.” If that is the case, the mini-split system is not at fault. It is simply working as per your instructions. If only life were that simple. Alas, there could be several reasons behind the mini-split system, not heating. Some of them are:
1. Frozen evaporator coils due to insufficient refrigerant.
2. A faulty circuit.
3. Defective sensors.
How To Fix – The first thing to do is to check the thermostat setting. Ensure that it is set to heat with the correct temperature. If that is as it should be, call your HVAC technician. He will have to open up the unit to figure out the exact cause and fix it, something you cannot do because of a lack of appropriate training.
5. No Dehumidification – In summers, the air conditioner needs to get rid of the excess humidity. Until it does that, no matter how much you lower the temperature, the indoors continue to feel uncomfortable and clammy. There are a couple of things that act as an impediment in adequate dehumidification by the mini-split system. These are:
1. Backed up water in the drainpipe due to a blockage.
2. An oversized unit will also be unable to dehumidify properly. Actually, it will cool the room faster but will not be able to extract moisture from the air.
3. An undersized unit will take longer to cool. It will also not extract humidity from the air at the same speed as a properly sized unit.
How To Fix – Fixing the blockage in the condensate line is easy. We discussed it right at the top in point number 1. What we did not tell you is that if you don’t want to do it yourself (which is no big deal), you can ask an HVAC tech to do it for you. Now coming to an oversized or an undersized unit, sadly, that is a mistake, an expensive one. There’s no way to solve the issue other than to buy a mini-split system that is adequately sized for your home. You can either use an online calculator or ask your local contractor for assistance to know the exact size.
6. Repulsive Odors – Handling odors is tricky because different odors indicate different trouble areas like musty or stale smell is indicative of mold, rotten egg odor points towards electrical problems, etc. To solve this issue, you need expert help.
How To Fix – The best person to fix this is your HVAC technician, so call him without wasting any time.
7. Does Not Start – If your mini-split system doesn’t turn on, check the electrical supply. Maybe there’s no electricity in your area, the unit is unplugged, or the circuit breaker has tripped.
How To Fix – Restoring the power supply will have your mini-split unit humming happily. If it’s still not working, ensure the circuit breaker is in the “On” position and not tripped. If it still does not work, call a trusted technician.
