Ductwork Installation In Baltimore, MDDuctwork installation in Baltimore, Lutherville-Timonium, Ellicott City, MD and the surrounding areas requires a little planning and a five-step process that we’ve outlined for you below to make things as easy to understand as possible. But we’ve also listed a series of common mistakes, so make sure to read through to the end!

What Are the Basic Functions of Ductwork?

Your ductwork system is installed so that it can distribute airflow from the HVAC unit and into every room.

The airflow that is being taken in and then put out could tell you how efficient your ductwork system is. Sometimes insufficient heating or cooling is due to poorly designed return ducts, for example, too small in size, poorly located, or not enough number of return ducts. Lack of well designed return ducts causes lack of circulation and limits hvac system ability to cool or heat the entire home evenly.

Please keep in mind that if your house or building also has sets of pipes that transport water, gas or refrigerant, they do not belong in the same category as ductwork. This only refers to air.

Types of Ductwork

  • Rigid ductwork – it’s made from sheet metal and it’s sealed and insulated. Rigid ductwork is very durable which is why it can be installed as part of a duct that goes on the roof.
  • Flexible ductwork – this one is made of plastic tubes that are very flexible and covered in insulation and wire frames as well as a plastic cover. They are the proper choice for tight spaces since they are easier to install.
  • Insulated ductwork – you will find that most types of ductwork are covered in fiberglass as insulation. However, reflex is now a more modern and popular choice as well.

The Ductwork Installation Process

  1. Install the ductwork starting with the unit. Use the sheet metal kind and duct tape to wrap around every joint. It will seal it tightly.
  2. If you can, run some ductwork among the floor joists. Hold it in place using galvanized hanging straps.
  3. Add the pieces that approach every vent or that register in your home.
  4. It’s time to add the return ductwork. Start at the main unit once more. Work your way out just like you did the first time.
  5. Turn the thermostat as high as it can go to test the ductwork you’ve just installed.

Common Mistakes When Installing Ductwork

  • Not installing a support for the flex ducts every four feet. That could cause the ductwork to sag, which might mean that the air flow is a lot lower while the friction could be higher.
  • Not insulating the supply lines in their entirety. It’s not enough for the spaces the ductwork goes through to be insulated, the ducts have to be so as well.
  • Not fastening two pieces of ductwork together with a rigid connector. Don’t just flex them inside each other.
  • Don’t forget to insulate the butt joints. If you do, then the supply air could leak out.
  • Not testing the ductwork after installing it. This could lead to serious issues not being discovered until it’s too late.

Good Ductwork Is Crucial for a House

The first thing you need to understand is that the ductwork is highly important for your house. Your HVAC unit will only be as effective as your ductwork is and even the best one on the market will fail efficiency-wise if your ductwork is poor and old.

In other words, if your ductwork is not running properly, some 20 or 30% of all the cool or hot air that’s supposed to run into your house will actually be lost in the attic. The air conditioner itself might break down sooner because of an inefficient duct system.

We recommend a ductwork replacement if it’s too old and is now putting a strain on your unit.

Ductwork Replacement vs Repair

Once you’ve determined that your ductwork is faulty, you will have to choose between repairing it and replacing it altogether. If you can still perform a few good repairs, do them. There’s no need to go for a replacement which is pricier.

However, there are a few situations in which a ductwork replacement is absolutely necessary.

  • Your ducts are made of very cheap materials. This could mean they will break down multiple times and will end up costing a lot more than the replacement
  • The system is older than 10 or 15 years. This is usually the breaking point when every ductwork starts to slowly deteriorate.
  • You’ve discovered the plastic ducts are covered in mold. Cleaning them is not a solution in this case. But if they are made of metal, you can get them professionally cleaned.

Please remember that your ducts are only one part of your entire HVAC system. Therefore, the ductwork installation process is crucial to how well or efficiently it functions.
