What Mini-Split Maintenance Includes

We don’t just inspect your mini-split when doing seasonal maintenance ductless tune-ups. We find and fix hidden problems, like water leaks from clogged drain lines or reduced airflow from dirty coils. Our expertise covers electrical connections, refrigerant charging, and thermostat calibration. We’ll have the whole system performing at peak efficiency so you can enjoy a more reliable setup.
Here’s what our mini-split repair prevention services include:
  • Clean and replace air filters
  • Inspect indoor and outdoor units
  • Check refrigerant levels and leaks
  • Clean coils, fins, and drainage

Filter Cleaning and Replacement

We start the maintenance process by cleaning the mini-split filters. Most systems have two: a primary mesh filter and a secondary specialty filter. You should proceed after the maintenance visit with cleaning or vacuuming the mesh filter every two to four weeks. This type of seasonal maintenance ductless care greatly improves air quality and system efficiency. Secondary or specialty filters typically need replacement every 6 to 12 months.

Indoor and Outdoor Unit Inspection

Next, we give the rest of the indoor parts (coils, fan, and electrical connections) a thorough inspection. If we find any loose wires, leaks, or damage, we’ll fix them right away. Addressing small issues one by one will help the system perform better without the worry of sudden breakdowns. After inspecting the indoor parts, we go outside to look at the condenser and fan blades. These parts need adequate airflow at all times to maintain their energy performance. If we have to, we’ll clear debris and trim vegetation so everything has proper ventilation at all times. The refrigerant lines may need extra insulation to protect them from heat loss and condensation buildup.

Checking Refrigerant Levels and Leak Testing

We’ll check the refrigerant lines to make sure they don’t have any leaks. Even small pinhole leaks waste energy and cause major issues with cooling and efficiency. Fixing the leak may require patching or line replacement.

Cleaning of Coils, Fins, and Drainage

Cleaning dirt and debris off the coils and fins leads to better efficiency thanks to improved airflow. We check the drainage lines to ensure all condensation can flow freely; this prevents issues with water buildup and mold growth so the system operates optimally at all times.

Delaying mini-split repair prevention will only cause efficiency problems to become worse. This can translate into higher energy bills that are easily preventable with the right approach. Acting fast with a maintenance visit is the best way to avoid costly breakdowns.

Have questions about mini-split repair prevention? Our team provides easy-to-understand answers that give you confidence and peace of mind.

How often should filters be cleaned or changed?

You should clean mini-split filters every two to four weeks. If your setup uses a specialty filter, it will likely need a replacement every 6 to 12 months. This simple but very important step improves your comfort, boosts indoor air quality, and assists with system efficiency.

Yes, Koch & White ductless service works on all brands. We’re very familiar with doing tune-ups on wall-mounted, ceiling cassette, and floor-mounted style mini-splits. We make it simple to enjoy better comfort and energy efficiency year-round.

What does a mini-split maintenance visit cost?

The cost of a mini-split maintenance visit depends on the size and condition of your system. Those that require major repairs or refrigerant replacement tend to cost the most. However, most visits normally range from a modest fee to a few hundred dollars.

Will regular maintenance improve indoor air quality?

Yes, that’s one of the biggest perks of regular mini-split tune-ups. By making sure everything has sufficient airflow, the system doesn’t have to operate with added strain. This does much more than reduce dust and allergens. It also helps reduce humidity problems by making sure there isn’t any excess moisture buildup.
