Mini-split systems are a favorite among Florida homeowners and for good reason. They’re energy-efficient, flexible, and perfect for keeping your home cool without the need for extensive ductwork. But if your mini-split is suddenly struggling to keep up with the heat, it’s a sign something isn’t quite right.
If your system isn’t cooling like it used to, don’t panic. The issue may be minor and fixable with a little maintenance, or it may require a quick visit from a professional. Either way, here’s a breakdown of common reasons your mini-split might be underperforming.
1. Dirty Filters and Coils
Let’s start with one of the most common culprits: dust and debris. Mini-splits rely on clean filters and coils to circulate air efficiently. When filters get clogged or coils collect grime, airflow is restricted and cooling power drops.
What to do:
Check and clean your filters at least once a month. If the coils are visibly dirty, it’s best to have a professional clean them thoroughly to avoid damaging delicate components.
2. Low Refrigerant Levels
Mini-splits use refrigerant to absorb and transfer heat. If there’s a leak or the system wasn’t properly charged during installation, cooling performance will suffer.
Signs of low refrigerant include:
- A noticeable drop in cooling power
- Ice forming on the indoor or outdoor unit
- Hissing sounds coming from the system
What to do:
Refrigerant issues should always be handled by a licensed technician. Not only is refrigerant handling regulated, but low levels often indicate a leak that needs to be addressed before simply adding more.
3. Blocked or Obstructed Airflow
Check the area around your indoor unit. Are there curtains, furniture, or artwork blocking the vents? Even partial obstructions can reduce your system’s ability to distribute cool air effectively.
What to do:
Make sure there’s at least a few feet of clearance around the indoor unit. Free airflow allows your mini-split to cool your space evenly and efficiently.
4. Improper Installation
If your mini-split has never quite performed the way it should, installation could be the root of the issue. Undersized units, poor placement, or bad refrigerant line connections can all result in long-term cooling issues.
What to do:
If you suspect installation wasn’t done properly, a professional inspection can confirm the problem and suggest the right solution, whether it’s adjusting the system or replacing components.
6. It’s Just Getting Old
Even the best mini-splits don’t last forever. If your system is over 10 years old and struggling to cool like it used to, it may simply be time for a replacement. Newer models are more efficient and offer advanced features that could save you money in the long run.
