Frequently Asked Questions (FAQ's)

Why choose 25-ft line sets instead of 16-ft?

This allows more flexible condenser placement for larger homes or longer routing paths.

Yes. MRCOOL® DIY® QuickConnect® technology eliminates vacuuming and refrigerant handling.

Can each zone be controlled separately?

Absolutely. Each air handler operates independently with its own thermostat and remote.

Does this system support smart control?

Yes. Control via the MRCOOL® Smart HVAC Controller® App, Alexa®, or Google Home®.
