How HVAC Ducts Work – Denver Colorado

The HVAC duct system is the heart of the heating and cooling system in the home. Duct systems provide a path for air to flow throughout the home. They can be made from fiberglass duct boards, sheet metal or insulated plastic. A combination of these materials can be used in the same house.

The duct system comprises three main parts. The first part is the return air which provides the path that air from each room can pass to the inlet of the furnace. This unit cleans the air and introduces fresh air. Moisture can also be added (in some cases) in this section.

The next part is the furnace or air handler. It is the section where heat is added or removed for the comfort of the home. The filtering was done in older systems. This led to service problems.

The final part is the supply section which delivers conditioned air to each room in the home. There are two major types of supply systems which are extended plenum and central plenum. In a central plenum system, all the branch ducts start at the same location. This location is called plenum. The extended plenum has a supply air plenum that connects to the outlet of the HVAC unit. The main supply ducts are connected to this and run to the end of the home. Their size is often reduced to ensure that the air flow is maintained. The branch ducts (which are attached to the main ducts) transport the conditioned air to each register.

What to Do If Your System is Noisy
The major signs of an inefficient HVAC system are whistling, popping or wheezing noise. These signs signify that that the system is working harder than it should be. If this condition is not attended to, then utility bills become abnormally high and the unit becomes unable to keep the home comfortable. Intervention is needed to save the HVAC equipment.

If it is a new system, then it is possible that the ducts are wrongly sized or the system is not well balanced. If it is a sizing problem, you can retrofit a zone system. This, however, can be expensive. If there is too much air being delivered into a room, a damper can be closed to reduce the amount of air being released. If the amount of air being delivered is too small, a duct booster fan can be installed. If the system is not new, then the filter should either be cleaned or replaced.

If you don’t intend to do all these steps yourself, then you need to select an HVAC contactor that can assist you in this process. Get in touch with us for a free estimate today!
