What to watch out for when buying your air-conditioner system

This is why Ductair recommends and manufactures only metal ducting fittings, which - like most air-conditioners - are made of steel.

But just in case you need further evidence, the list below are the additional downfalls.

Inferior Plastic Fittings:

• Can warp and come loose
• Can crack and leak air
• Can break altogether when they warp and crack simultaneously over time
• Can melt! Beware of ‘el cheapo’s.
