Ductless Air Conditioner Preventive Maintenance

We always suggest homeowners consider professional maintenance and tune up services at least once a year, however, there are some maintenance measures that homeowners can take themselves. A regular maintenance not only improves an appliance's efficiency but also increases its lifetime.
But before you set up your boat for maintenance, keep in mind to shut off all types of power supply.

Filter Cleaning

The Ductless or the Mini Split systems have an indoor evaporator unit. This unit is equipped with Filters that are meant to trap dust and debris. These filters if not cleaned regularly affect the system's efficiency. Although it is recommended to follow the user manual to check how often does your unit need cleaning, it is better to clean more often if you're allergic or have pets at home.

Condenser Cleaning

The second component that comes in DIY maintenance tasks is the condenser cleaning, Switch the power supply off and using a garden hose, spray dust and debris on the unit mainly on the coil. It is highly recommended to avoid high pressure since it can cause the fins of the fan to curve. If accidentally, some fins get curved, straighten them using a special alignment comb before turning the unit on.

Ductless System Maintenance Checklist

As said earlier, it is highly recommended to let a professional technician examine your unit at least once a year. And to make sure that the professional you hired has done a complete job, here's a checklist:

Check Electrical Connections

All connection inside and outside the unit are checked to stop the possibilities of any short circuiting, wire damage and overheating. Not only are these connection need to be checked, the faulty ones should be repaired as well.

Check Run Capacitor

Run capacitors need to be checked for leaks, bulging or deformation. In case a Run Capacitor is found to be faulty, a technician is supposed to replace it.

Check Refrigerant Leaks

Refrigerant Leaks if not suspected and fixed in time give way to serious repair needs. All the refrigerant lines need to be checked for any possible leaks. The leaks should be patched or lines replaced.

Check Drain Hose
From the evaporator unit, the hose that runs condensation should also be on a professional's checklist. The hose should be able to allow a free flow of condensation.

If all the above mentioned preventive maintenance tips are practised, an annual maintenance tune-up from a professional is taken and any repairs whenever needed are fixed in time, the appliance is 80% likely to last longer than other's and most likely to complete (or even surpass) its lifetime.
