Frequently Asked Questions

Everything you need to know about this product

Can I install this myself without an HVAC license?

Yes — the DIY series uses pre-charged Quick Connect line sets that tighten by hand. No vacuum pump, no refrigerant handling, no EPA 608 certification required. Most single-zone installs take 4–8 hours. You may still need a permit and an electrician for the 240V circuit, depending on local code.

What if it arrives damaged or I change my mind?
