Selling ductless? Great! Make sure to get your customers on a regular preventative maintenance schedule
Regular scheduled maintenance is a win-win
If you are one of the growing number of contractors who sell and install ductless split systems, don’t miss out on the opportunity to sell maintenance agreements on this equipment as well. Not only is a maintenance agreement profitable for your business, it will help to ensure customer satisfaction with the equipment and with your company. Be sure to educate your customer of the importance of a regularly scheduled inspection and cleaning service. Cleaning the equipment will keep it operating at peak performance and will remove dust, dirt, and mold from the blower wheel, drain pan, and vanes of the indoor wall-mounted unit that would otherwise be circulated into the room. A maintenance agreement should be a basic part of your ductless sales presentation.
Scheduled maintenance should be done at least every six months — more frequently in areas where the equipment is running day in and day out. The preventative maintenance checkup should include a thorough cleaning of the indoor and outdoor unit. There are several cleaning kits available that can do the job. Some work better than others, but all essentially do the same thing.
Take the time to properly clean the indoor unit
Your first step should be to shut off power to the system before performing any cleaning or service. To clean the indoor unit, you can choose from several ductless cleaning kits. Many utilize a ‘bib’ that attaches to the wall-mounted unit to collect the runoff of cleaning solution and water when the coils are cleaned and rinsed. The runoff funnels into a 5-gallon bucket for easy disposal.
A thorough cleaning of the indoor unit is a more labor-intensive procedure; remove screws, end panels, cover panels, and the air vanes to remove the drain pan and gain access to remove the blower wheel. All the parts should be cleaned, rinsed, and dried. Reassembly can be tedious, and even for the experienced ductless tech, this type of service can take a few hours to perform.
New ductless design reduces time on the job
Coming soon, a new design feature on Friedrich Floating Air® Pro and Premier ductless wall-mounted units called FastPro™ will allow the blower wheel, motor, and drain pan module to be removed as one component more easily and with considerably fewer steps. This will save the technician hours of time on the job. The new design will allow less experienced techs to gain confidence in performing what would otherwise be a daunting task. Friedrich expects that the new design will reduce cleaning time by 50 percent. The Friedrich Floating Air Pro and Premier ductless lines will be available in the second quarter of 2019.
Continue the deep clean outside
When cleaning the outdoor unit, again, be sure power to the unit is off. Remove any debris from the unit, as leaves and dirt will build up over the season. Clean the coils thoroughly with a cleaning solution specifically formulated to remove the dust, dirt, grime, and mildew that builds up over a season’s use. Rinse the coils thoroughly and allow them to dry completely.
Visually inspect all flares for any sign of oil. Check that the wire terminals are all tight and secure and that there are no loose wires from regular use. Be sure to check that the drain line is free and clear of debris and flows freely. Also check that the exterior end of the drain is located so that condensation water can drain without restriction. These steps ensure your product will perform at its most optimum levels until the time comes to reinspect and provide your customer with the next scheduled preventative maintenance.
Finally, check the unit’s performance
Once the cleaning of the indoor and outdoor units is completed, you should check the system to be sure it is operating to spec and as designed. Restore power to the system and set to the desired setting. Check for delta temperatures between the inlet of the indoor unit and the outlet, and results should be a 15° to 20° split. This will ensure you are providing adequate cooling to the conditioned space. Listen for any unusual noises, and run the system through its settings.
Let your customer know the system is operating properly, and inform them of the next scheduled preventative maintenance.
