Upgrading Older Mini-Splits to Modern Inverter Technology

Older mini-splits often used basic rotary compressors that lacked advanced humidity control. Modern inverter systems dynamically modulate compressor speed between 20 percent and 100 percent capacity, removing moisture continuously while consuming a fraction of the electricity required by older units.

Frequently Asked Questions

In many cases, existing linesets can be flushed with solvent and pressure-tested with nitrogen if they are the correct diameter. If the previous compressor burned out with acid contamination, installing new linesets is required to protect the new unit.

With proper annual maintenance and clean filters, quality ductless mini-split systems last 12 to 15 years in the Houston climate.
