Ductless HVAC Maintenance Services in Houston, TX

Mini-splits rely on precise refrigerant levels to cool properly. If refrigerant is low, your system may blow warm air, run longer cycles, or stop cooling altogether. We use specialized gauges to check pressure and verify the system is charged to manufacturer specs. If we detect signs of a leak — including oily residue or pressure imbalance — we’ll pinpoint the problem and explain your repair options. Catching a leak early can save your compressor from damage and avoid costly breakdowns.

A ductless system has several sensitive electrical parts — from the control board to fan motors and sensors. Loose connections, faulty capacitors, or failing sensors can cause communication errors or system shutdowns. During routine maintenance, we inspect all terminals, test components under load, and verify that safety switches are working correctly. If something looks off, we’ll recommend service before it becomes a bigger issue.

Your ductless system removes moisture from the air as it cools. That water drains through a narrow pipe that can clog with algae or debris. If left unchecked, this leads to water leaks or musty smells. Our team flushes the drain line, checks for blockages, and ensures proper slope for drainage. We also inspect and clean washable filters in every indoor head, which keeps air flowing smoothly and helps maintain air quality in your home or office.
