Hot and sweaty weather is the worst, and an AC unit is usually the only thing keeping us sane when those heat waves strike. But if we want our AC units to keep pumping out that cool air, we need to make sure we keep them clean at all times.
A dirty air conditioner often results in it breaking down or working less efficiently than usual. The good news is that they are fairly easy to clean, and if you’re trying to figure out how to clean carrier split air conditioner then guess what? We’ve got you covered in this guide.
Steps for Cleaning the Indoor Unit
- Cover the unit in a cleaning bag to prevent all the dust and grime from being blown around your home. They are cheap to buy and really easy to fit.
- Switch off the AC at the unit as well as in your fuse/breaker box. This keeps you safe and prevents potential electric shocks.
- Remove the air filters and take them to the kitchen sink to be washed. These should be easy to pop out, but always check the manufacturer’s guide first. You can then rinse them under running water, using a sponge for any rough areas or caked-on dust and grime.
- Blow the dust off the cooling fans using compressed air or an actual blower. Make sure it uses a gentle force so as not to cause any damage. You can then use a no-rinse evaporator spray on the coils to get them back in top condition.
- An antifungal spray on the coils will also help to reduce the risk of mould and mildew, which is a common issue with AC units. If the filters need replacing, you can also do this while you are cleaning up the coils.
- Flush the drain lines to clear any clogs and keep the system running smoothly. The lines should be left to dry for at least one hour after to ensure the water and cleaning fluid used has evaporated. Follow the manufacturer’s instructions when draining the lines and cleaning them.
- Switch it back on to make sure everything is working and operational. Make sure you keep the cleaning bag on for the first few minutes so it can capture any leftover dust.
Steps for Cleaning the Outdoor Unit
- Switch off the power both at the unit and the fuse/breaker box. You will need to ensure that it’s completely unplugged as this process includes washing the unit, so stay safe.
- Vacuum the condenser fins using the dusting brush attachment on your vacuum cleaner. This is because it’s gentle on the unit while also removing dust efficiently. Inspect the fins, and use a knife to straighten any that are bent so that it is operating to its full potential.
- Unscrew the outer lid of the unit and take out the fan. Make sure to do this carefully and follow any manufacturer instructions. It’s also wired to the condenser so it can only be partially removed. However, this will allow you to take the garden hose and rinse the fins off thoroughly.
- Leave the fins to dry completely and then put the outdoor unit back together again. Make sure you put everything back in the correct place and that it’s completely secure. You can then switch the power back on and test that it is working.
At the most, this process should take you no more than a day including drying times. It’s quick, easy, and will leave you with an air conditioning unit that is functioning at its full potential. This process should be done every month or so to keep on top of things, and never left for more than six months.
