Frequently Asked Questions

Is this compatible with standard residential ductwork?

Yes, this uses industry-standard sizing compatible with all residential HVAC duct systems.

Can I install this myself?

Yes, most ductwork components are DIY-friendly with basic tools. Use foil tape (not cloth duct tape) and mastic sealant on all connections for an airtight seal.

Should I use duct tape or foil tape?

Always use aluminum foil tape or mastic sealant on HVAC ductwork. Cloth "duct tape" dries out and fails within 1-2 years. Foil tape lasts the life of the system.
