FAQs

Why is my ductless split not working? ›

If your mini-split system keeps shutting off, a common cause is a faulty thermostat or a problem with the power supply. A blocked condensate line or an overloaded circuit could also be the culprit. Regular maintenance and professional inspections can help identify and resolve these issues promptly.

While conventional air conditioning units typically offer a service life of around ten years, ductless mini-split systems can last up to 20 years, especially under ideal conditions. This impressive longevity places them among the most durable home appliances available, highlighting their value for money.

You should always schedule an annual inspection, cleaning, and tune-up with one of our heating, ventilation, and air conditioning (HVAC) professionals at least once a year. Our experienced technicians will do a comprehensive check of your ductless system and recommend any needed maintenance.

If your air conditioning unit has stopped working, many possible reasons can explain why. It could be your thermostat, your air filter, a problem with the condenser or compressor, or it may just be time to replace the unit, especially if it's over 10 years old.

A mini split can be left running 24/7 because the systems are designed specifically for non-stop use. In fact, keeping your mini split system running actually makes it more energy efficient and increases its ability to regulate temperatures with its internal temperature settings.

Every 4-6 weeks, inspect and clean the indoor unit's air filter, following the manufacturer's recommendations. For your safety, turn the system off before opening the cabinet. With the power turned off, clean dust and dirt from inside the cabinet using a small vacuum or dry cloth.

Ductless fans can't tolerate accumulated debris, and if you fail to clean the filters, costly professional cleaning will likely be required, or the performance and lifespan of your system could be severely impacted. Though ductless systems do provide heating, heating capacity is limited to certain climate zones.

The mini split is operational in cool mode at temperatures of 64 to 109 degrees Fahrenheit or 18 to 43 degrees Celsius. Daikin mini splits: Most Daikin mini splits have exceptional hot and cold tolerance. In heat mode, the unit can handle temperatures of 5 to 75 degrees Fahrenheit or -15 to 24 degrees Celsius.

Cleaning the air filter, coils and other components can help resolve your issues with your mini split not blowing cool air, but if you suspect a refrigerant leak or your system won't turn on at all, it's probably time to contact a licensed HVAC technician.

Dirt, rocks, leaves, and other types of debris can accumulate around the mini-split, preventing it from moving air correctly. Ice and snow can also be an issue in the winter. It's a good idea to regularly inspect your outdoor unit, clean it, and move away materials if necessary so that air can circulate.

Can I clean my mini split myself? ›

To clean the coils of the exterior unit, use a coil cleaner and a hose. Once interior mini-split cleaning is complete, check the condensate pan like you did when you cleaned the indoor unit. If you notice any mold growth, consider using a bleach solution to remove it, and then rinse the pan with water.

Failing to vacuum a mini split can affect more than the airtightness of your ductless mini split. The unit might not be able to accept refrigerant at full capacity, which can cause condenser pressure to go up and down because of the different condensable gases in the system.

Mini split systems that are installed properly and not damaged should not require a regular refrigerant charge.

The main reasons your AC unit outside is not turning on could be something that has tripped the circuit breaker, something is blocking the fan's airflow, or the condensing unit is damaged. Other potential issues could be the thermostat isn't set correctly or the compressor could be malfunctioning.

Common Reasons Why Your Air Conditioner is Not Turning On

Resetting your thermostat is often all that's necessary to get it working again. A tripped circuit breaker is another common reason why your AC won't turn on. Using too many appliances at once can trip the circuit breaker.

The first thing you should do if your mini-split isn't powering on is to ensure the unit is plugged in. Check your circuit breaker to ensure it wasn't tripped due to an electrical surge. If everything seems like it should be fine, you may need to call a professional repair service or replace the unit altogether.

System not running at all: If the system isn't running at all, you might have an electrical issue. Start by making sure the system is turned on. Then, check the breaker box to make sure your home's power supply is providing power to the system.
