Is It Necessary To Replace Ductwork When Replacing a Furnace?
You might find it tempting to keep your old ductwork in place when upgrading your home with a new furnace. After all, not having to install new ductwork means less money spent on the installation. However, just because you have old ducts in place doesn’t necessarily mean they’re worth keeping.
A lot of older homes rely on ductwork that has severe damage, leaks, and airflow restrictions. That’s why professional installation is so important for a furnace replacement. One of our workers can do a thorough inspection to help determine whether you need new ductwork.
Risks of Keeping the Old Ductwork
To make the right decision for your home, it helps to understand the downsides of using the old ducts. Many homeowners find it best to go ahead and replace the ductwork to avoid these issues.
Leaky Ductwork Wastes Energy
Your ductwork has multiple joints that connect different vents to the furnace. When these joints become loose or misaligned, it leads to air leaks. Leaky ductwork is a top cause of energy waste that makes heating systems work harder. You may notice your energy bills going up and uncomfortable living spaces as the conditioned air escapes through the leaky spots.
Outdated ductwork is very likely to have several leaks. In a lot of situations, it’s best to replace the ductwork instead of trying to fix all the leaks. Replacing a furnace provides the perfect time to upgrade the ductwork because the workers already have the system torn apart.
Dirty Ducts Block Airflow and Reduce Efficiency
Older ducts often have dust and debris accumulation inside them that reduces or even blocks airflow. Getting them cleaned professionally may provide enough improvement to make them worth keeping.
A technician can evaluate their condition and test airflow to see what the best choice is. Ducts with excessive damage and deterioration will almost always need a replacement. You don’t want your new heater to operate with airflow restrictions because they increase wear and tear and cause premature repairs and replacements.
Damaged Ductwork Increases Air Quality Problems
Damaged ducts don’t just cause airflow problems; they also contribute to air quality issues. They do this by allowing pollutants and dust to escape into living spaces through gaps and leaks. This can increase allergy and asthma symptoms while also making it harder to keep the home clean of dust.
New ducts will eliminate these potential issues by preventing unfiltered air and contaminants from entering the system. The heater will perform more efficiently with optimal airflow that improves the home’s air quality instead of hurting it.
Improper Sizing Causes Uneven Heating
Improper duct sizing can cause major issues with the new furnace. If we find the ducts aren’t the right size, we’ll identify them as a necessary upgrade. Ducts that are too large cause problems with airflow velocity and uneven heating. Ducts that are too small lead to restricted airflow. Proper sizing results in balanced airflow that helps the new heater perform better and last longer.
Poor Sealing Allows Heat Loss
Your old ducts may be in good condition but have poor sealing. If this is the case, we might be able to reseal them and use them with the new furnace. Sealing is particularly important for making sure there isn’t any heat loss as it travels from the furnace, through the ductwork, and then into each room.
Old Materials Break Down Over Time
Outdated duct materials become brittle and damaged over time, especially ones exposed to moisture and pests like mice and insects. If the home has flexible ducts, these may sag or tear. Old metal ducts will often corrode, and some may even separate at the joints.
These older materials make the heating system less reliable because they don’t maintain proper airflow. Instead, they leak air, which ends up causing energy loss, uncomfortable living spaces, and higher energy bills.
Signs to Replace Your Ductwork During a Furnace Replacement
Now that you understand the risks of leaving the old ductwork in place, it’s time to carefully consider your situation. If any of the following applies to your home, we will likely recommend doing a ductwork upgrade during the furnace replacement process:
- Multiple rooms have weak airflow
- Noticeable temperature differences between rooms
- Utility bills keep rising without changes in usage
- Visible crushed, torn, or disconnected duct sections
- Excess dust coming from supply vents
- Whistling sounds or air leaks near ducts
