A ductless HVAC system may be small and, of course, there aren't any ducts to worry about – but these systems still need maintenance, especially if it's been a while since you looked at it or if your system is facing a lot of work in the future. Let's take a look at a few important steps to take when maintaining a ductless heating and cooling system so that it is well prepared for the future.
Tend to Your Filters
Ductless systems tend to use a multi-stage filtration system, so it's important to look at the exact type of filters that you have. If you have metal filters that attract dust particles, then it's important to remove and clean them every several weeks – all you need for these is a damp cloth. Your system also probably has fabric filters that are designed to pick up smaller particles. These filters can start getting clogged and slow down air flow after several months of use, so it's important that you replace them at least a couple times a year. Finally, if your unit uses HEPA filters then you will need to replace them regularly, often every 60 days – check your filter instructions for more information.
Clean the Compressor, Condenser and Evaporator
These are the key components of your system, both outside and inside. However, over time dust and debris can settle on these components, impairing how well they work. Evaporator coils, in particular, will struggle to exchange heat if they are coated in dirt. Take a cloth and wipe these components down to make sure they are clean and there's no debris stuck anywhere near them. You may also want to spray an anti-bacterial spray on your coils to prevent any mold or fungus from growing there when you aren't looking!
Get Your Refrigerant Levels Checked
Your refrigerant powers the heat transfer process, but it may slowly leak out over time without you noticing. If it's been a few years, you should also arrange to check the refrigerant levels of your unit. This is a job best done by a professional who can quickly adjust refrigerant back to the right sweet spot.
Have Electrical Connections Checked
A professional can also check the electrical connections and wiring on your unit to make sure that everything is functioning correctly, and that there are no signs of fray wiring or corrosion that could spell trouble.
Why It's Important to Think About Maintenance Now
As you consider the maintenance your ductless system may need, remember that the time heading into fall and winter is a particularly important time to get all your maintenance tasks finished. Your HVAC system has a lot of work to do during the colder months, and since homes are well sealed during these times, there's little access to outside air, and the same dust or allergens can circulate around a home for months (less so than with ductwork, but it can still be a concern). To help your system prepare for its hard work ahead and make sure dust doesn't get trapped in your home, it's a good idea to get your maintenance tasks done before the cold weather comes!
