FAQs

What are the alternatives to ducting? ›

Alternatives to air duct systems include window-mounted air conditioners, boilers and radiators, and ductless mini-split systems.

Ductless mini split systems are smaller than traditional central air systems and don't require extensive ductwork to distribute the chilled air. This makes them much easier to install in a house.

Air duct replacement cost depends on factors such as location, home size, and building material. Additional factors, such as installing vents or insulation, can also add to the bottom line. Depending on the job's scope, replacing air ducts may require permits and repairs that can boost the overall cost.

Sheet metal ductwork, often considered the most energy-efficient ductwork, is a type of duct system made from durable materials like galvanized steel or aluminum. Its benefits include exceptional durability, resistance to damage from pests, and smooth surfaces that reduce air resistance, enhancing airflow efficiency.

To answer the question of whether or not you can replace or install your own ductwork, I'd say it is possible but that I highly recommend enlisting the help of a heating, cooling, and ductwork expert. Ductwork runs all throughout your house, which makes doing DIY repairs yourself a heavy contracting lift.

Sheet Metal Ducts

Rust-resistant sheet metal ducts can be round or rectangular, and while they may be more expensive to install than flexible ducts, they're more sustainable. Sheet metal ducts are considered the most energy-efficient material because of its exceptional durability and enhanced airflow.

Turn on a Ceiling Fan

Ceiling fans are great for moving air around, especially in stuffy rooms, and they can assist in keeping the room cool or warm, depending on the direction that the fan turns. Over the summer, be sure your ceiling fan is moving counterclockwise—this will move cool air down toward the floor.

How Long Does It Take to Install a Ductless HVAC System? The time it takes to install the system varies. Since these systems are designed for minimal installation, many projects can be completed in 1-2 days. If you have multiple wall-mounted units, the installation process may take a bit longer.

If your older home has limited space, a mini split system will enable you to improve the heating and cooling without installing large, unwieldy equipment. Most mini splits are only about a foot high and twice as wide. The limited space requirements make it easy to get them up and running without much effort.

Ducts are designed to last for about 10-15 years on average. They are made from a combination of materials such as fiberglass and plastic. At some point, these ducts will get damaged. The sooner you see signs of damage and do something about it, the better.

Is metal ductwork better than flex? ›

Metal ductwork is typically more expensive than flex duct, but it is also more durable and long-lasting. Flex ductwork is less expensive, but it may need to be replaced more frequently due to wear and tear.

Key Takeaways. Ductwork typically requires replacement every 10-15 years, and delaying this can compromise airflow and energy efficiency. Visible and subtle signs, including excessive dust, strange noises, and increases in energy bills, can indicate deteriorating ductwork that needs repair or replacement.

Rigid ducts are more durable than flexible ducts and can withstand extreme temperatures. They don't require much maintenance and last a long time. Rigid ducts are more efficient than flexible ducts. Their smooth surfaces and straight design won't interfere with airflow.

Consider aluminum ductwork if you're looking for a more affordable option. Aluminum is lightweight, flexible, and easy to clean and install. While it may not be as durable as galvanized steel, this type of ductwork will still last a long time. This is one of the most common ductwork options for residential clients.

The most common is the 'branch and duct' layout, but another option is the 'home run' layout. A trunk and branch system has a large main supply and a large main exhaust duct (the trunks) that are connected to the ventilation unit itself.

Air ducts are one of the most important systems in any building as they carry cool or warm air throughout the building, ensuring comfort year-round. However, if ducts are poorly installed or maintained, they are probably contributing to higher energy bills.

Typically made from galvanized steel or aluminum, sheet metal ducts are also highly popular in HVAC systems — and for good reason. These types of ducts are easy to work with (and thus, fairly inexpensive) and they're great at reducing air leakage in homes.

PVC is considered a good option for mitigating the risk and is often used to comply with mandated safety regulations. In homes, PVC ductwork can allow a heating and cooling system to run beneath the house without being corroded by moisture or even radon. Over time, metal ductwork can rust and will need to be replaced.
