Installing ductwork for furnace

Some people think that the do-it-yourself type of situation is more money-saving than hiring an HVAC professional to work with your air conditioning system. Technically ductwork can be installed on your own, but it is highly advisable to seek professional HVAC work for your duct installation.

How should ductwork be installed?

Always install flex duct in as straight a run as possible flexible duct should be supported at least

Is installing ductwork difficult?

Proper ductwork design and installation is difficult work and requires special training.

Which is better round or square ductwork?

Round air ducts are best suited for high-pressure HVAC systems. Their design creates less friction, allowing air to flow easier throughout the building. Rectangular ducts aren't as efficient with their airflow, which means they can create more harm than good in a high-pressure system.

Is flex duct better than hard duct?

A key difference between flexible and metal ductwork is that flex duct is notoriously easier to install. It's lightweight and can bend however is necessary in order to adapt to the heating or cooling system. Installation goes much faster, reducing the cost of labor and downtime for your business.

Is installing ductwork expensive?

On average, the cost for installing ductwork is anywhere from $1,900 to $6,000, with the national average being around $4,000. That's assuming you're having 300 linear feet of aluminum ducts replaced, plus insulation and 10 vents and two returns.

What shape of duct is most efficient?

Air Duct Shapes Round – typically the most efficient in transporting air. They utilize less material than rectangular ducts and still handle the same amount of air. Rectangular – these ducts are made to fit building construction.

What type of ductwork is best?

Flexible ductwork is the best type of ductwork to use in tight or awkward spaces where rigid ductwork would be too difficult to install. Because these air ducts are flexible, they can bend around fixed structures to work in almost any space.

Should vents be pointed up or down?

As a general rule, AC vents should point upward (but not enough to narrow the openings too much). This allows cold air to displace hot air before sinking. An exception is when the vents are located on the walls right below the ceiling.

Do you have to open walls to replace ductwork?

Unless your home has a flat roof (which means the ducts are very difficult to access), we can usually install new ducts without ripping out walls or ceilings.

Can I do my own HVAC ductwork?

What is the lifespan of ductwork?

Ductwork has a maximum lifespan of 20-25 years. By 15 years, however, it begins to deteriorate, significantly reducing your HVAC system's efficiency, so replacement is the prudent option.”

Is it better to undersize or oversize ductwork?

Oversized Ducts Larger than normal ducts are certainly capable of handling more airflow. But your HVAC system may not be equipped to pump that much air. In fact, your system needs a specific air pressure in the ductwork to properly distribute air.

Is metal ductwork better than Flex?

For a more long-term solution, metal ductwork is a much better choice. Flexible ductwork is made of a thin, pliable material. Not only does this make it less durable than metal, but it also means that flexible ducts are more likely to become damaged in the short term.

How do I know what size duct to use?

Cubic feet per minute is calculated by multiplying the size of the HVAC unit (in tons) by 400. Divide the answer by your home's square footage to find out total CFM. A duct sizing calculator uses CFM and other factors to determine what you need.

What is the main problem with flex duct?

Too often, flex ducts are not installed properly, and they end up kinked, bunched up, undersized, or sagging. These issues can cause increased resistance in the duct system, resulting in too little airflow reaching a building's heating and cooling equipment.

Can flex ducts grow mold?

Mold in Flex Ducting and HVAC Airhandlers The cold surfaces of the ducts and air handler in contact with the humid air provides a condensation effect which allows for mold spores to colonize in the dusts of these materials.

How far can flex duct be run?

E. 1. Flexible duct shall be supported at manufacturer's recommended intervals, but at no greater distance than four feet. Maximum permissible sag is 1/2 inch per foot of spacing between supports.

Does new ductwork increase home value?

Installing a new HVAC system could increase your home's value by as much as $2,500-$3,000 or approximately 5-10% of the total value of your home.

Why is HVAC ductwork so expensive?

Conclusion. When it comes down to it, the most expensive parts of any HVAC unit installation will be the machine and the labor. The device is so expensive because it is filled with complicated electrical gadgets that measure airflow and temperature.
