Duct Installation
The most important part of installing new ducts is making sure the ductwork is the right size. When thinking about why your ducts need to be a specific size, consider this: Imagine if someone told you to blow through a paper towel tube as hard as you could. It would be difficult, wouldn’t it? Now imagine that same person telling you to blow through a drinking straw as hard as possible. That’s not easy either, is it?
It’s the same with your ducts! If your ducts are too big, the blower fan is going to have to work much harder to move air all the way through your home. If your ducts are too small, the fan is going to move more air than the ducts can handle, forcing it to cycle on and off constantly. Suffice it to say, if either of these is true of your ducts, even a 95 AFUE furnace isn’t going to run very efficiently!
At James A. Wheat & Sons, we begin our duct installation process with an inspection of your home, during which we take into account the size and layout of your home as well as the capacity of your HVAC system. After we do this, we can optimize your duct design and installation for your particular home.

Frequently Asked Questions About Duct Installation & Repair
How can I detect leaks in my ducts?
One of the first signs of a leaky duct is a decreased level of comfort in the home. If you are operating your furnace or air conditioner but still not enjoying the desired temperature, or if rooms are different temperatures, there is a good chance you have a leaky duct.
Is duct tape the best way to seal a leaky duct in Gaithersburg?
It may surprise you, but duct tape is not the best solution. The best option is to use cement mastic. This seals the leak and keeps contaminants from entering your airflow.
Do ducts need to be insulated?
Insulating your ductwork can significantly improve your comfort. The insulation helps ensure that the cool/warm air that travels through the ducts doesn’t heat up in summer or cool down in winter. This improves the efficiency of your HVAC systems and enhances your comfort.
How often should ductwork be replaced?
Most ducts will start to show their age between 10 to 15 years. After this point, leaks and other damage will begin to take their toll and reduce your ductwork’s effectiveness. Replacing the ducts can protect your home against pests, diminished indoor air quality, moisture infiltration, and more.
How long does it take to install ductwork in a residential home?
Most ductwork installations take one to two days to complete. It all depends on the size of the home and how much work is required to ensure a proper installation. It is easier and faster in new construction because there is no need to work around furniture. Before any installation, our certified HVAC teams will give you an accurate estimate of the time required to complete the installation of new ductwork in your home.
How much does new ductwork cost in Maryland?
New ducts can run anywhere from $5,000 to more than $10,000 based on the size of the home, zoning considerations, etc. As always, we provide a reliable estimate for your home and work with each client to ensure the finished installation will deliver the comfort you desire.
