Keeping you cool is our business.
Whether you’re constructing your new family home, office, commercial building, adding a new room, or remodeling an outdated structure, the AC ductwork is an important, but challenging step. We at Simplex Ducting may be biased, but we highly advise that you hire a professional contractor to install ductwork for you. If you’re not interested in doing the heavy lifting, we’re happy to help!
If you’re considering doing the job yourself, there are some things that you should know before getting started. First and foremost, it’s important to be aware of common missteps that often lead to inefficient AC systems, which means high electricity bills.
The most common mistakes made when installing ductwork include:
In order to get started, you’ll need to properly equip yourself with a hammer, a screwdriver, and a sabre saw. You will also need sheet metal screws, metal hangers, tin snips, and material for duct pipes and fittings.
Common material used for air ducts:
If done correctly by a team of professionals, the process to install adequate ductwork throughout a new home is about one to two days. Doing the work yourself can take even longer, especially if you’re doing so with little to no experience. It’s important to schedule the right amount of time to fit into your construction project and to understand what steps to take.
Step 1: Design and Planning – The preparation is the most important phase. This includes mapping out the design of your system, which should cover the pathway, the location for vents, the returns, and understanding how much it will take to cool each room. You should make sure you have the proper materials and the right amount of materials to properly size your ductwork.
Step 2: Installing the Plenum – The plenum is the brains of the operation. This is the chamber that collects the air straight from the furnace or AC unit. This is also where your main trunk lines will originate.
Step 3: Installing the Main Trunk Line – This is the spine of your air conditioning system, or the main lines of air distribution from the plenum, extending the entire length of the structure. Remember to use a cap to halt the air at the end of the line.
Step 4: Installing Branch Runs – The branch runs are the limbs, or branches, of your AC system, allowing air to move from the main trunk line into specific rooms and spaces within your home. These are attached to the main trunk line and extend to the pre-planned vents. It is essential to make sure that you are using the proper joints, which will vary according to which material and shape of duct pipes you are using.
Step 5: Installing Returns – Based on simple laws of physics, you can’t be pushing air into a room without making sure that enough air is being extracted to make room for it. This is why it is essential to make sure you are installing return vents and pipes to properly circulate air. The number of returns your structure will need and where to install them will largely depend on the structure itself and where air might collect.
There are so many variables and risks that you take when venturing into AC duct installation. If you don’t have the experience or knowledge of AC systems, or the support of an equally experienced team behind you, installing your own duct system can end up being more costly than it’s worth. Your best bet is to call a professional to make sure the job is done right the first time.
