A home’s HVAC system is heavily relied upon during weather extremes. Whether it’s getting through that miserable blizzard in December or that scorcher of a heatwave in July, your unit gets you through the elements. Some homeowners have opted for ductless systems to avoid complex installation in their households, finding that they do just as good a job when it comes to heating and air conditioning. However, it’s important, as a homeowner, to stay vigilant of any issues with your ductless mini-split. Here are a few issues to look out for and ways to get your system running like new.

Electrical Issues


One of the most obvious signs that your ductless system is in need of repairs could stem from improper use of the system. While it doesn’t hurt to open your windows or doors to get some cross-ventilation, it will immediately decrease the effectiveness of your ductless AC unit. By introducing warm air into your household, you’re putting more pressure on a ductless HVAC system during the summer months. This can lead to later equipment malfunctions that may cause noise, like a clanging brought on by overuse of the ductless unit.

The simplest trick to keeping your ductless system delivering consistent temperatures is to use it as needed. Oftentimes, homeowners will leave their HVAC unit running all day long to ensure hot or cool air when they get back from work or school. Reduce use with a younger unit to extend the lifespan, limiting to when you are home and when opening a window just doesn’t do it.

Refrigerant Leak


If you’re noticing puddles around your outdoor unit, it’s possible that you could be dealing with system leaks with refrigerant seeping out, preventing an air conditioner from doing its job during those hotter days of summer. A refrigerant charge must meet specifications set by a system’s manufacturer. However, if there is a crack or leak in the outdoor unit, adding more refrigerant is simply a waste. Refrigerant should not be handled by homeowners and should be left to professional technicians who are equipped to use this and make any repairs safely.

If you notice that your condenser coil is melting or leaking, that’s an early warning sign of potential problems with your HVAC unit. The leaks are also environmentally dangerous to both your outdoor system and can also impact your indoor air quality. After all, most people opt for a ductless HVAC system in their household to avoid high energy consumption. You’re just going to be scrambling to turn the thermostat down on your AC system, but all you are doing is letting more fluid seep out and putting greater pressure on the equipment.

Lack of Maintenance


Issues that emerge for ductless mini-splits could stem from something as simple as a lack of proper maintenance. For example, it’s important to maintain a regular cleaning regimen to scrub or change air filters. A clogged air filter can restrict airflow, keeping warm or cool air from doing its job when you need it to. Unclean heating systems can adversely impact indoor air quality, putting dust and other allergens back into recirculation, triggering asthma and allergy symptoms.

Keeping vegetation and debris away from an outdoor unit is almost important to prevent any possible burnout within the wiring. Be sure to completely shut off the power before taking on proper maintenance. If you don’t feel sure about yourself, don’t hesitate to contact a repairman to handle this for you. Having an HVAC technician inspect your unit at least annually is also worthwhile to keep an eye out for any issues you may be missing. You may be dealing with drainage issues and not even realize it.
