If your ductless mini-split system keeps shutting off before completing a full cooling cycle, swift, professional repair is crucial. Commonly known as short-cycling, this problem significantly derails your home’s comfort. Here are four reasons why your ductless mini-split keeps switching off in your Punta Gorda, FL, house.
Compressor Issues
The compressor unit plays a vital role in the refrigerant cycle of your ductless HVAC unit. Essentially, the compressor unit dictates the refrigerant pressure throughout your AC system.
Excessive overheating in the compressor is among the major culprits behind frequent shutting off in ductless mini-splits. Additionally, older compressor units are more susceptible to sudden failure. It’ll help if you upgrade the compressor unit as your ductless mini-split system gets to its peak working lifespan.
Low Refrigerant Level
Low refrigerant levels could also be the reason behind recurrent short-cycling. Typically, proper ductless mini-split operations require the refrigerant levels to meet a consistent threshold amount. If the refrigerant levels don’t meet this threshold, your system becomes incapable of making a complete cooling cycle.
Low refrigerant levels hinder your system’s cooling ability and energy efficiency. Frequent maintenance identifies refrigerant leaks, ensuring proper refrigerant amounts.
Frozen Coils
The evaporator coils cool the air within your home’s indoor atmosphere. Ice buildup on the evaporator coils hinders their efficiency while drawing away warm air from your indoor space. Routine maintenance eliminates ice accumulation in the evaporator coils, ensuring sufficient cooling all spring.
Dirty air filters further aggravate the issue of frozen coils. Cleaning or replacing your filters every month is also helpful to prevent short-cycling.
Thermostat Failure
Short-cycling could be an indicator thermostat is gradually beginning to malfunction. Faulty thermostats detect improper temperatures, causing wrong turning on and off of the AC system. Professional repair or replacement will help to fix thermostat failure.
