My System Is Noisy
So, how will you know that your hvac duct system is sick? One of the first symptoms will be a whistling, wheezing, or popping noise. This is a sign that the system is working harder than normal to maintain your comfort. It is like the beginning of chest pains for a heart patient. As the condition gets worse, the next symptom will usually be an abnormally high utility bill. Many times this will go unnoticed until the unit is unable to keep you comfortable. This is where the situation gets really critical. Intervention is required to save your heating and air conditioning equipment.
If this is a new system (less than a month old), it is likely that the ducts are not properly sized or the system is not properly balanced. For an improperly sized system, there are a few things that can be done to minimize the effects. The first thing is to retrofit a zone system but this can be expensive. If too much air is being delivered to a room, a damper can be partially closed to lower the amount of air. Many registers have a built in damper to allow you to do this. If there is not enough air being delivered to a room, then a duct booster fan may be installed to increase the amount of air delivered to the room. If it has been operating for a month or longer, the system filter may need cleaning or replacement.
