What Causes These 3 Ductless AC Noises in Locust Grove, VA?
Ductless mini-split systems are typically quiet when they operate. Any noise from your mini-split could indicate a serious problem. Being able to recognize these noises can help you address them effectively and keep your mini-split in Locust Grove, VA, running effectively. Here are three noises you may hear from your ductless AC system:
Bubbling
A ductless mini-split system makes a hissing or bubbling sound if air bubbles form inside the refrigerant line. The bubbles form when the line is leaking. Any leakage in the refrigerant line is a serious problem that can lead to refrigerant loss and a system breakdown.
The sound can also indicate the presence of excess moisture in the system. This moisture forms when the drain line leaks water into the system due to cracks, holes or a blockage.
Rattling
A rattling or grinding noise in a ductless mini-split system can be due to various factors, depending on whether it comes from the indoor or outdoor unit. If it comes from the outdoor unit, the noise could be due to loose or broken parts hitting against each other or debris swirling around.
Grinding noise from the indoor unit could be due to excess friction from damaged bearings. Our service technicians can add air handlers with well-oiled bearings to reduce friction between moving parts. These bearings need regular maintenance by a professional service technician to remain in good condition.
Buzzing
Different reasons can cause buzzing or vibrating noise in the condenser unit, but the most common ones are electrical system faults and loose or broken fan blades. Electrical issues can significantly reduce your ductless AC system’s energy efficiency, exponentially raising your monthly bills. Even worse, they can cause serious system breakdowns if you don’t repair them promptly.
Ignoring any noises can damage your ductless AC system. Call Custom/Design Heating & Air Conditioning for the best AC repair services in Locust Grove, VA.
