If you're having a new heating and air conditioning system installed in your home, then it might pay for you to replace your old ductwork. Even though some people have HVAC systems installed and then just use their new systems with their old ductwork, replacing your old ductwork with brand new ductwork is sometimes the better idea for these reasons.
1. Make Sure the Ducts are Big Enough
For one thing, if your ductwork is old, then the ducts themselves might not be very big around. This means that the airflow from your new HVAC system might not be able to travel through the ductwork effectively, so you might not get maximum power out of your new system. Having new ductwork installed can help you make sure that the ductwork is of the proper size so that you can truly enjoy your system and keep your home at a comfortable temperature.
2. Avoid Issues from Holes and Other Damage
Another thing that you should think about when you're dealing with older ductwork is how the ductwork might be damaged. Over time, holes and other damage can occur to ductwork. This becomes a problem because any holes or other damage make it possible for the warm or cool air from your HVAC system to leak out of your ducts instead of traveling through the ducts and throughout your home. If you're wondering if your ductwork has damage, you can ask your HVAC technician to perform a blower test. With a blower test, air will be forced through your ducts, and the air that comes out of your vents will be measured. This will help show you whether or not your existing ductwork has damaged, which can make it easier for you to determine whether or not the ductwork needs to be replaced.
3. Start with a Fresh, Clean Slate
When you install a new heating and air conditioning system in your home, you do not want to have to worry about dirty and dusty air being pushed through your home by your new unit. If you have your older ductwork replaced first, you can start out with a fresh, clean slate. This means that you don't have to worry about dust or pet hair that might be clogged in your ductwork or any mold spores that might have started growing deep within your ductwork, where you cannot easily see it. Instead, you'll know that everything is brand new, just like your new heating and air conditioning system.
