Maintenance Of Ductless Mini-Splits
Your system should be serviced at least twice a year. Routine maintenance helps it run efficiently and can spot potential issues that can be corrected before further damage occurs. These are some of the most essential maintenance tasks to keep your ductless mini split system running at its best.
- Clean the Condenser Coils: Cleaning the coils is a more complicated task than most people are used to. If you’re comfortable completing it without a professional, first turn off the power, which cools the system down and prevents electric shock, and make sure there is at least four feet of clearance, with no obstructions like leaves, branches, or furniture, around the outdoor unit. Once it is off for an hour, clean the coil with a soft, dry cloth, and look for condensation, ice, mold/mildew, and other problems; a mold preventing or antibacterial agent can be sprayed on as well. For the most part, treat the condenser as a central air conditioning unit. Look at the refrigerant lines, insulation, fan wheel and blower assembly, and other components as well as verify the unit is properly secured to the base. Call a professional if something doesn’t seem right.
- Clean/Change Filters: Cleaning or replacing filters (which depends on the type) is the most basic form of maintenance. Filters should be inspected monthly or more frequently depending on use and demand. Replace a dirty and/or old filter or clean it per the manufacturer’s instructions. Some filters can be cleaned with a HEPA vacuum. But make sure to follow all recommendations as a clean filter keeps the system running efficiently, decreases wear, and improves air quality.
- Clean IAQ Components: Any components designed to improve indoor air quality should be removed and cleaned on a routine basis. The types of components vary based on the system and manufacturer. Examples include negative ion air purifiers, UV light devices, air scrubbers, and MERV filters. Keeping these components clean is the best way to ensure they provide the best IAQ advantages.
- Repair the System If Needed: If the mini split system is acting up, consult with a trained professional to determine if it needs repairs. Oftentimes, simple problems can be fixed before they turn into more serious, and expensive, issues. You can even prolong the life of the system. Signs that a mini split air conditioner may need repairs include:
- Higher Bills: You might not immediately attribute a higher electrical bill to the condition of your A/C system, but older units become less efficient. A mini split should last 12 to 15 years. If your unit is relatively new, additional energy consumption can mean many things; there may be a clogged filter, defective equipment, or the system may be short-cycling.
- The Controls Don’t Work: Remote controls most often stop working due to dead batteries. If changing the batteries doesn’t fix the problem, try to turn the unit on manually. If it fails to start, an electrical problem or faulty reversing valve may be to blame. A valve issue may also lead to a lack of cooling.
- No Cool Air: When there’s a refrigerant leak, the system cannot produce cool air. The decrease in cooling capacity may occur gradually over time as refrigerant often leaks slowly. Once it has completely drained, the system can only function as a fan that doesn’t provide temperature control.
- Ice: If the outdoor unit’s cooling coils become icy, it can be due to reduced air flow. The coils may then freeze over. A clogged filter, damaged fan, leak, dirty coil, or faulty thermostat may restrict air flow enough to ice up the coil, which can weight it down and cause warping.
- Noise: Ductless mini splits are generally quiet. If you hear grinding sounds from an indoor unit, it might have worn motor bearings. The problem should be addressed quickly, or else the air handler motor may overheat and burn out. Banging sounds can be a sign of a serious problem that may lead to system failure.
- Pooling Water: A clogged condensate line cannot drain moisture collected from indoor air. It can cause water to back up, which can form puddles on the floor, trigger mold growth, or cause all types of damage to belongings and building materials.
- Inconsistent Performance: If your ductless A/C is healthy, you’ll have a consistent supply of cool air. But if temperatures are fluctuating, uneven, and don’t match thermostat settings, there is most likely something wrong in the system.
