A mini-split air conditioning system is an efficient and cost-effective way to cool your home or office. Like any HVAC system, mini-splits need regular maintenance to ensure efficient operation, otherwise components can malfunction causing you to not be as comfortable as you like.
If your mini-split isn’t cooling as it should, there are several possible causes to consider.
First, problems can occur when filters aren’t cleaned or changed regularly. Dirty filters can restrict airflow, causing the system to work harder and not cool as efficiently. It is recommended to clean or replace air filters at least every three to six months and more often if you live in a dusty environment.
A second reason your mini-split is not cooling properly is the refrigerant is low. If you suspect your refrigerant isn’t at the proper level, contact Merts Heating & Cooling to have one of their trained HVAC technicians remedy the situation as soon as possible.
Another possible cause of a warmer than usual indoor environment is the thermostat may not be set at the correct temperature or it may not be set to cooling mode.
It’s very important for proper cooling that the outdoor unit of a mini-split air system has proper airflow. To keep air flowing freely, always make sure the unit isn’t blocked by debris or plantings.
Faulty wiring or a blown fuse may also cause your mini-split to stop cooling. Check the circuit breakers or fuse box to make sure they don’t need reset or replaced. If you think a more serious electrical problem may be the cause, always hire a professional electrician to help.
Other problems that require the expertise of a trained HVAC technician or comfort specialist are dirty condenser coils or having the wrong size mini-split unit for the room. A dirty unit will never operate at peak performance. Having a unit that is too small or too large will cause comfort issues for the occupants.
In conclusion, if your mini-split isn’t cooling, there could be several reasons why. Regular maintenance and proper installation can prevent many issues. If you are experiencing problems with your mini-split, contact Merts Heating & Cooling to schedule one of our skilled technicians for diagnosis and repair.
