One of the advantages of installing a ducted air conditioning system is that most of the system's components remain out of sight, which is great for aesthetics. However, it is crucial to ensure that you do not neglect these out-of-sight components, especially the ductwork.
Here are among the common issues that affect the ductwork in a ducted air conditioning system, what they mean for your system, and what to do about these problems.
1. Undersized and Oversized Ducts
Undersizing or oversizing are common installation mistakes for ducted air conditioning systems. If your system's ducts are too small, there will be an increase in static pressure, which will create some noise as air moves through your system. On the other hand, if the ducts are too big, the pressure will not be enough to push the cooled air throughout your space, which will cause your system to overwork. Accurate load calculations are the only way to get the sizing of your ductwork right.
2. Clogged Ducts
Dirt, dust, and other debris may still find their way past your filters into the ducts. Rodents such as rats have also been known to get into an AC system's ducts and leave their waste there. This build-up of particles and debris will reduce the airflow and affect your ducted air conditioning efficiency. The dusty air will also aggravate respiratory problems and allergies.
Scheduling a professional duct cleaning is the way to go if there's too much of a build-up of dirt and other debris in your ducts. Most HVAC contractors provide this cleaning service for residential and commercial clients with ducted air conditioning systems.
3. Leaky Ducts
There are several reasons why your ducts may start to leak. If the installation was done poorly, then it may not be too long before the leaks start. Leaks can also result from cracking of sealing material such as caulk and overall deterioration of the ducts. Ducts made from plastic and fiberglass are also more susceptible to leaks, as the bending of these ducts tends to create spots where the material gets loose.
Leaky ducts will decrease your system's efficiency, which will drive up your energy bills. Depending on the underlying cause and the extent of the leakage, you may need duct repairs or replacing the ductwork to get your ducted air conditioning system back to top shape.
Get the best and most out of your ducted air conditioning system by getting the size right, keeping them clean and sealing off leaks, and repairing any damaged sections as soon as possible.
