For homeowners in Pinehurst, NC who value simplicity and want to simultaneously have different temperatures in different parts of a building, ductless mini-splits can be an excellent alternative to traditional HVAC systems. Although extremely reliable, these systems can have occational issues. Here’s how to troubleshoot some common problems with ductless mini-splits.
Leaks
Typically, when something leaks out of your mini-split, it will be either water or refrigerant. When it’s refrigerant, you will either notice an ether-like odor or, if it leaks out in gaseous form, hear a hissing sound. Since refrigerant is toxic, the proper way to deal with such leaks is to ask trained professionals for help.
When water leaks from your mini-split, it usually happens because of an airflow restriction. Once enough debris accumulates on the filters of any of your system’s air handler units, it will prevent air from passing over the unit’s coils. Consequently, the temperature in the unit will drop, and any condensation there will freeze.
When the system enters defrost mode to melt the ice, water will leak out. This is why you must remember to change or clean your filters about every two weeks.
Strange Sounds
Besides a short-lived clicking after startup and a low hum that continues through general operations, your mini-split shouldn’t make noise. So, any noises usually mean trouble. For example, rattling sounds generally indicate debris inside your system and a need for the services of an HVAC maintenance technician to clean it out.
Unpleasant Smells
Your mini-split should not emit any odors at all. The characteristic smell of refrigerant is only one of the smells you need to stay alert for.
For example, since the system runs on electricity, you might smell something burning if a stray electrical spark is burning a wire. If excessive condensation makes spores grow within the system, you may also notice a musty smell.
The ultimate solution for all of these issues is to ask for help from an experienced team of HVAC technicians. Call us at Sandhills Heating, Refrigeration & Electrical for top-notch ductless services in Pinehurst, NC.
