Why Ductless HVAC Systems Need Regular Maintenance

Ductless mini-split systems are efficient and flexible, but like all HVAC equipment, they need consistent upkeep to stay reliable. Without regular maintenance, these systems can suffer from airflow restrictions, dirty coils, refrigerant issues, or electrical faults — all of which reduce comfort and raise energy costs. At Champion and Nash, we provide professional ductless HVAC maintenance for homes and businesses across Houston. Our certified techs check, clean, and test every component to help your mini-split run at peak performance, season after season.

Is your ductless system not responding to remote input or displaying the wrong temperature? Faulty remotes and miscalibrated thermostats are a common source of trouble. Our team tests communication between the indoor unit and remote, recalibrates sensors, or replaces components when necessary.

Cleaning Indoor Coils for Better Efficiency

Over time, dust and debris build up on the indoor coils of your ductless system, making it harder for the unit to cool your space. This buildup forces the system to work harder, reducing efficiency and increasing your energy bill. At Champion and Nash, we gently clean your coils and internal components during routine maintenance, helping restore proper airflow and ensuring smooth performance all season long.

Checking Refrigerant Pressure and Leak Risk

Low refrigerant levels are a common cause of poor ductless performance. If your system isn’t cooling like it used to, or if you hear hissing sounds, there could be a leak. We inspect your system’s pressure levels and check for any signs of refrigerant loss. If needed, we’ll recharge the system to proper specs and discuss repair options to prevent future leaks and restore comfort.

The Benefits of Scheduling an Air Conditioner Tune Up Before Summer

Schedule your AC tune up before Houston’s heat hits. Champion and Nash helps you avoid breakdowns, lower bills, and stay cool all summer long.

Inspecting Electrical Parts and Sensors

Ductless mini-splits use circuit boards, sensors, and fans that must work together to keep things running smoothly. When a sensor misreads temperatures or a capacitor fails, the entire system can shut down. Our team inspects all electrical components during maintenance to ensure everything is connected, calibrated, and operating safely — helping you avoid unexpected outages.

Clearing the Drain Line and Cleaning Filters

Every ductless unit has a small drain line that can clog with dirt or mold. When that happens, water can leak onto your walls or floor. During maintenance, we clear the drain line to prevent moisture buildup and clean or replace washable filters to improve air quality. With proper drainage and filtration, your system stays healthier and lasts longer.
