Not sure which system you need? Erick will assess your space and recommend the right size and configuration—no upselling, just honest advice.
Ductless systems lose less energy than traditional AC (no leaky ducts). High SEER ratings mean lower monthly costs.
Installation only requires a 3-inch hole through the wall. No tearing up ceilings or floors for ductwork.
Control each room independently. Keep bedrooms cool while saving energy in unused spaces.
Most mini-splits are heat pumps—they provide both cooling and heating in one unit.
Indoor units run at 19-25 decibels—quieter than a whisper. Sleep peacefully while staying cool.
Most single-zone installs completed in 4-6 hours. Multi-zone systems typically done in 1 day.
