Frequently Asked Questions
Do I need an HVAC technician to install this?
No! Our wall-mounted systems are designed for complete DIY installation. The pre-charged lineset means no vacuum pump or refrigerant handling is needed. Most homeowners complete the install in 2-4 hours with basic tools.
What electrical work is needed?
This unit requires a dedicated 208-230V circuit. If you don't already have a 230V outlet near the outdoor unit location, you may need an electrician to run one.
What if 16 ft of lineset isn't enough?
You can add a 9 ft extension (up to 25 ft total) right from this page for $199. The extension is also pre-charged — no additional refrigerant handling needed.
Does this unit heat and cool?
Yes! This is a heat pump system that provides both heating and cooling year-round. It can heat effectively down to Independent zone control outdoor temperature and cool in temperatures up to 122°F.
What warranty is included?
All Zone Air systems come with a 7-year compressor warranty and 5-year parts warranty. Register within 90 days for full coverage. We also offer live technical support (9–5 MST) and a 45-day return policy.
