Sooner or later, it happens to every homeowner. Maybe you’re planning a big party or a family gathering. Temperatures are in the 90s. And your mini-split system won’t turn on. Even if you weren’t planning on hosting guests, it’s never convenient to be without effective climate control in your home.

However, sometimes the problem isn’t as obvious as a unit that won’t turn on. There are usually signs that your mini-split system needs repairs, even before it stops functioning completely.

Knowing these signs can help you call for professional ductless repair services right away, potentially avoiding more costly problems.

Here are some common signs your ductless mini-split needs repairs.  

Lack of Heating or Cooling

If your unit isn’t heating or cooling at all, it might be caused by a refrigerant leak, a clogged filter, or a compressor issue.

Decreased Air Flow

Weak or uneven airflow means the system isn’t circulating air as it should, which can make your home’s climate less than comfortable. If the mini-split is blowing out some cool or warm air, but not enough to heat or cool your home, the blower might be broken. There’s also a possibility there’s an issue with the outdoor unit, which the trained technicians at Schebler Heating and Air can troubleshoot.

Strange or Unpleasant Odors

If you turn on your ductless mini-split and immediately think, “What’s that smell?” it could indicate a variety of problems depending on the specific odor. Electrical issues, mold in the unit, or debris in the air filters can all cause unpleasant smells and serious problems in your DeWitt home. Call for ductless mini-split repair right away to prevent a potential home fire or illness caused by breathing mold.

Releases Warm Air

If your ductless mini-split is set to cool but is blowing warm air, it could indicate a refrigerant leak, a thermostat issue, or a problem with the condenser coils or fan. An expert can troubleshoot the system to determine the problem and take the right steps to restore proper cooling.

Increased Energy Use

If your electric bill is higher than usual for the time of year, it could be that your electric company increased the rates. But if that’s not the case, it could indicate an issue with your HVAC system.

Ductless mini-splits typically cost less to run than other HVAC systems because they’re more energy-efficient. But if your mini-split is using more energy than usual, it could signal a need for repair or maintenance. Clogged filters or malfunctioning components can decrease the efficiency of your mini-split, leading to higher electric bills. In the long run, you’ll save money by having the unit professionally repaired.  

Strange Noises

Ductless mini-splits are typically quiet. Unlike an in-wall AC, they don’t contribute to noise pollution in your home. If the system starts to make loud, strange noises like rattling, grinding or buzzing, it could indicate a mechanical issue, typically with the compressor or fan.

Leaks

Water leaks can have several different causes – some are serious and some are easy to fix. A clogged drain line can cause leaks around the outside of the unit. Similarly, if the drain line is cracked, torn, or even kinked, it can cause leaking. A clogged or dirty drain pan can also cause leaks. Finally, if the evaporator coils on the outside unit are leaking, it could indicate a dirty or clogged filter.
