How to Connect Metal Duct

Connecting metal ducting can be relatively simple if you have the tools available. For the most part, metal ducts are prepared with connection in mind. The ends have male and female connections. This allows them to slot into each other.

However, depending on your set-up, and the length of your ducting, installation could become more complicated. In some instances, you may require ducting connectors. For a comprehensive and smooth installation, we recommend having your ducting installed by a professional.

What happens if my metal duct isn’t connected properly?

If the connection to your metal ducting is not connected properly, you will find that air will escape from the ducts, making them far less efficient than they should be. There is also a chance they can disconnect.

Metal ducting that is not connected properly can also be a health hazard, due to the ducting being loose and having the potential to fall because it is not secure.

Additionally, metal ducting that is not connected properly has the risk of developing mould. As the contrasting temperatures inside and outside the duct can result in condensation forming in or outside the ducting.

If left untreated, this condensation can quickly become mould. Mould is known to have serious health implications on people. It has the potential to spread exponentially, if it has spread within your ducting, it would need to be replaced all over again.

Here are some steps you can take to prevent mould on your ductwork:

• Before installing the ducting, make sure the area doesn’t have any leaks or is next to anything that can generate a lot of heat, such as a heating pipe.
• Remove any mould in the room where the ducting will be placed.
• Insulate the ducting
• Track the humidity of the room with a hygrometer.

Should you cut metal ducting?

If the ducting is not flexible, you should not cut it unless you have the tools handy to safely and cleanly cut metal, or have a professional to do it for you. Flexible ducts can be cut with no issue.

Can a professional install my ducting for me?

Yes. HVAC technicians offer services which can include installation of a HVAC system and its ducting for most if not all kinds of properties. Please note that the complexity of the job at hand could alter the price if there are no fixed rates for certain services.

Alternatively, you can install your ducting yourself, as long as it ends up being compliant to part F of building regulations, and does not compromise the safety of any person in the property.

Though this second option can be especially difficult if you have no experience, equipment, or guidance. If you are struggling, please feel free to contact us, and we may be able to point you in the right direction.

Should I insulate metal ducting?

Although you don’t have to insulate your ducting, it is beneficial to do so. Insulation helps to maintain a consistent temperature through the ducting as a whole. This prevents the opportunity for humidity or condensation to form.

In addition to this, insulation also adds an extra layer of durability, although it isn’t exactly made to sustain damage in the first place.

What is the most efficient way to have ducting set up?

To make the most of your ducting system, and ensuring it stays secure, it should be insulated, connected with no looseness and installed with as little turns as possible. Making sure that your ducting is as straight as it can be helps to maximise airflow with the ventilation system it is paired alongside.
