The Importance of Replacing Ductwork for Optimal AC Performance

As an HVAC specialist with years of experience, I have seen firsthand the consequences of not replacing ductwork when replacing an air conditioner. While it may seem like an unnecessary expense, it is crucial to ensure maximum efficiency and air quality in your home. Most air conditioning systems last between ten to 15 years before needing a replacement, but modern units often require newer ducts to function properly. When old ducts are not compatible with the operating requirements of the new air conditioner, it can hinder its performance and lead to higher energy bills. That's why I always recommend replacing ducting when replacing an AC unit.

It's the best time to do so, as all contractors can easily adapt the new unit to the duct network without causing any harm. Did you know that approximately 25% of the air in your air conditioning ducts is lost due to leaks and poorly installed ducts? This can result in hundreds of dollars wasted each year. But don't worry, there are solutions for this problem. You can upgrade your ducts or consider air duct replacement services before it's too late. Read on to learn how to spot duct problems and what to do in those cases. On average, ducts are designed to last between 10 to 15 years and are made from a combination of materials such as fiberglass and plastic.

However, when more than 20% of the air escapes, you'll end up seeing this reflected in your energy bill. Twisted or tangled ducts can also prevent the HVAC system from working properly and cause high energy bills. Fun fact: the first air conditioner was invented in 1922 and quickly became popular due to its effectiveness. Air conditioning and ducts work together to maintain the desired interior temperature, and if one of them is not functioning correctly, it can negatively affect your comfort. Most HVAC specialists can connect the new air conditioner to existing ducts in the house, as long as they are in good condition. When replacing your air conditioning unit, it's essential to replace the old ducts as well.

Dust, dirt, debris, and other contaminants often build up in old ducts over time, creating a musty smell throughout the house. In addition, insects or rodents can also obstruct the ducts, causing damage to the air conditioning system. Incorrectly sized ducts can also significantly reduce unit efficiency and lead to higher utility bills. That's why quality ducting and a first-class air conditioning unit are crucial for staying cool during the scorching summer season. Replacing old ducts can also correct any irregular distribution of air and ensure that your home stays cool throughout the summer.

Faulty ducts can create hot and cold spots inside the house, cooling one room while leaving another hot and uncomfortable. Residential ducts typically have twice the lifespan of traditional air conditioners and require replacement every 30 years. Your HVAC specialist will evaluate your ductwork and determine if you need to install a new ducting system after replacing your air conditioning unit.

Keep in mind that duct leaks can facilitate the entry of allergens such as pollen and small particles into your home.

By replacing old ducts before they are significantly damaged, you can save money on unnecessary repairs in the long run.
