Ductless mini-splits are generally safe, but there are some notable potential hazards, including refrigerant leaks. Let’s explore the top tips from experts on how to protect your household.
Know Where the Breaker and Outdoor Disconnect Are Located
Modern mini-split systems have two user-accessible electrical safety mechanisms: a circuit breaker located in your home’s electrical panel and an outdoor disconnect switch. In an emergency, turn off the outdoor switch, then turn off the breaker. At that point, it’s safe to call your local HVAC company for whatever help you need.
Shut Off the Power Before Cleaning
Mini-splits are powerful electric appliances, which means there are significant shock hazards when using water or cleaning agents. Before cleaning your mini-split system, turn off the power to the system. Wait for the system to dry completely before reenabling the power and running the cooling or heating.
Don’t Repeatedly Reset Tripped Circuit Breakers
An isolated circuit breaker trip once a month or less frequently is completely normal. If you experience multiple trips a month or more frequently, there’s an underlying electrical issue. Continuing to reset the breaker could damage the system and increase the risk of electrical hazards. It may be as simple as a worn breaker needing replacement, but it could also be a damaged wire or other serious issue.
Keep the Evaporator Coil Clean
The evaporator coil is an integral aspect of the refrigeration system. It creates condensation as a byproduct of refrigeration, which can lead to mold growth. Professional evaporator coil cleaning should be performed every year and is included in standard maintenance service. If you have a self-clean mode, you should activate it once a week during the cooling and, if applicable, heating seasons.
Regularly Check Condensate Drain Lines
Drain lines can also be a breeding ground for mold and pose a risk of leaks. At least once a month, check your system to ensure that the drip pan, wet switch, drain line, and condensate pump are working correctly.
Maintain a Clear Outdoor Unit
The outdoor unit houses many electrical components, including a fan and pump. Maintain a minimum 1-foot perimeter free of grass, bushes, and overhanging branches. If you notice a buildup of debris in the housing, use a blower to clear it.
Clean Filters Without Chemicals
Many mini-splits have reusable filters that you only have to replace annually. Clean those filters every two weeks to protect the system and your indoor air quality. Also, never use anything other than hot water to clean them. Cleaning agents can damage the filter mesh and leave behind traces that can circulate throughout your home as toxic fumes.
Don’t forget that your mini-split needs a tune-up every spring and, if it’s a heat pump, every fall. That inspection and cleaning will help you prevent most electrical and other hazards.
