If your mini-split isn’t providing the cooling it usually does in your home, there could be multiple reasons. Let’s run through them along with troubleshoots. Remember, if you don’t feel comfortable doing these troubleshoots, get in touch with us for a service call.
1. Incorrect temperature settings. This is the most common reason for your mini-split not sending out cool air into your home.
When the thermostat is set too low, the indoor air handler will constantly cycle on and off, failing to reach the desired temperature. On the flip side, if the thermostat is set too high, the air handler will constantly run without ever achieving the desired temperature. In either scenario, your mini-split will exert unnecessary effort, leading to higher energy bills. It’s crucial to strike the right balance to ensure optimal performance and energy efficiency.
Unlike central air conditioning, it is not advised to do big temperature shifts with a mini-split. Change the temperature less than 5° Fahrenheit, when, for example, you are either leaving for the day or coming home after work. Too much of a temperature swing reduces the mini-split’s efficiency.
Also, make sure the fan setting on your mini-split is at “AUTO.” This allows the mini-split to change fan speed to maximize efficiency while keeping the space at your temperature setting.
2. Dirty indoor air handler. Is the air coming from your mini-split smelling musty? That’s often a sign that the filter in your air handler needs cleaning, which can also impact how well your mini-split cools your space. If that doesn’t clear up the problem, there may be an accumulation of dust and dirt on the evaporator coil or within the condensate drain line. There are specialized cleaning products for these. If the problem persists, give AFC a call.
3. Low refrigerant or a refrigerant leak. There are various reasons why low refrigerant or a refrigerant leak can occur, including a hole in the unit, improper installation, or the natural wear and tear that comes with age. If you suspect this is a problem, or you discover a leak, get in touch with us and we’ll take care of it.
4. Problems with the outdoor condenser unit. The condenser plays a crucial role in extracting heat from the refrigerant, while the evaporator absorbs heat from the indoor air. If the outdoor unit’s condenser is not functioning properly, it can hinder the system’s ability to effectively cool the home. Possible reasons for a malfunctioning condenser can be attributed to factors such as aging, accumulation of dirt and debris, as well as damage resulting from bad weather.
