7 Tips for Your Ductless Mini-Split System This Fall
Is your ductless mini-split heating and cooling system ready for winter? Ensuring your mini-splits are in top condition as the seasons change is crucial for uninterrupted warmth and efficiency when temperatures drop in Knoxville, TN and East Tennessee.
These systems work tirelessly throughout the year, offering targeted heating and cooling without extensive ductwork — so preparing them for the colder months ahead is essential.
At Pipe Wrench Plumbing, Heating & Cooling, we strive to keep your HVAC systems operating at their best. By empowering homeowners with expert advice and professional service, we’ll help you maximize the lifespan and efficiency of your ductless mini-split system.
Here are seven tips to keep your ductless mini-split running smoothly and efficiently this fall.
Maintaining Your Ductless Mini-Split
If you’re new to owning a ductless mini-split system and want to ensure it runs at peak efficiency, regular preventative maintenance and upkeep are important to keep your system operating up to manufacturer standards and maintain warranty requirements.
By investing time in routine care, you can avoid unexpected breakdowns and costly repairs, keeping your home comfortable throughout the year.
Clean the Filters
One of the simplest and most effective maintenance tasks is cleaning the filters, as ductless mini-splits rely on constant air circulation in the indoor and outdoor components.
Over time, filters can become clogged with dust, dirt, and debris, particularly if you have pets, restricting airflow and reducing the efficiency of your ductless mini-split. A clogged filter forces your system to work harder and reduces system efficiency by up to 20%, increasing energy consumption and putting potential strain on the unit.
Clean your filter by:
Turning off and unplugging the system: Ensure the system is off and unplugged for safety.
Removing the filter: Open the front panel and carefully take out the filter.
Cleaning the filter: Use a vacuum with a brush attachment to remove dust. Rinse the filter with lukewarm water and mild detergent for a deeper clean.
Drying the filter: Let it air dry completely to prevent mold growth.
Reinstalling the filter: Place the dry filter back into the unit and close the front panel.
Turning the system back on: Plug the unit back in and turn it on.
To ensure optimal performance during the heating season, checking and cleaning the filters every one to two months is recommended.
Clean Coils
Cleaning your ductless mini-split coils is essential for maintaining optimal performance. Dust and debris can accumulate on the evaporator and condenser coils, reducing efficiency and increasing energy bills. Regularly cleaning these coils helps ensure effective heat transfer, prolongs the life of your system, and keeps your home comfortable.
To clean the coils, make sure the unit is turned off, gently brush away any visible dirt or debris, and use a coil cleaner or low-pressure water hose if necessary. Make sure the unit is completely dry before you turn it back on. Be sure to follow the manufacturer’s instructions for cleaning to avoid damaging the coils or bending the fins.
Clear Fall Leaves & Debris
Since it’s out in the open, your ductless mini-split’s outdoor unit is a magnet for leaves, twigs, and dirt.
To keep it running smoothly, check and clear away any debris that might block airflow. This simple step helps your system stay efficient and ensures you’re cozy all season.
To clear your outdoor unit, gently remove leaves, twigs, and other debris with a broom or by hand, ensuring there’s no obstruction around the unit for optimal airflow and performance. If you notice any damage to the unit or if it’s not functioning properly, contact us to inspect and address the issue before winter sets in.
Shelter Your Outdoor Condenser Unit
Protecting the outdoor condenser unit of your ductless mini-split system becomes essential as the seasons change and weather conditions become more unpredictable.
A properly fitted cover protects your equipment from harsh weather, falling debris, and other potential hazards. A professional-grade cover helps maintain your system’s efficiency and extend its lifespan by ensuring proper ventilation and airflow.
Ensure a Clear Space Around Unit
It’s important to make sure there’s ample space and distance around the ductless mini-split system to ensure it functions correctly. You don’t want to put furniture, bookcases and shelving, or picture frames close to the unit to prevent dust accumulation.
It’s suggested that you keep a distance of at least 4 feet in every direction around the mini-split, so be sure to keep your fall or winter holiday decorations at a proper distance.
Test Your Thermostat & Unit Operation
Testing your thermostat and unit operation is crucial to ensure everything runs smoothly. Regularly check that your thermostat accurately reads temperatures, and your unit responds correctly to settings. This simple check helps prevent surprises and ensures your system maintains optimal comfort and efficiency.
Check your system operation and that your thermostat is responsive by:
Adjusting thermostat settings: Change the temperature to see if the system responds.
Observing unit response: Ensure the unit turns on and off.
Using a separate thermometer: Compare room temperature with thermostat reading.
Listening for unusual sounds: Ductless mini-splits are supposed to quiet, so identify any odd noises from the unit such as grinding or squealing.
Checking for foul odors: Check for musty smells that could suggest mold or burning smells could signify an electrical issue.
Checking airflow: Confirm that air is blowing correctly and at the right temperature.
Testing both heating and cooling: Verify that both modes function properly.
Inspecting for error codes: Look for any error messages or indicators.
Schedule Professional Maintenance
While you can perform several maintenance tasks yourself, scheduling professional maintenance at least once a year is crucial for ensuring your ductless mini-split is thoroughly inspected and serviced.
A professional can perform a comprehensive check of all system components, including electrical connections, refrigerant levels, and overall system performance.
Regular professional cooling and heating system maintenance can help identify and address potential issues before they become major, more costly problems, ultimately extending the lifespan of your system and ensuring it operates efficiently all fall and winter.
