Benefits of insulating your HVAC ducts
Many homeowners overlook proper insulation of their ductwork.
Some homeowners even find it unnecessary as their HVAC systems with uninsulated ducts perform as they expect.
However, the reality is that much of your HVAC system’s efforts go to waste without duct insulation. Your HVAC ducts pass through your entire home at varying temperatures before they deliver air through the registers. Meaning, your system will have to overcome the temperatures inside your ducts before the required air temperature is delivered to all the rooms of your home. While your furnace in the basement will push air through your cold ductwork before it heats your home, your air conditioner will also have to push air through your warm ductwork before it can cool your home on a hot summer day. Heat transfer will always occur. It is a common obstacle that HVAC systems have to overcome during the initial operations. With duct insulation, your system will cycle frequently enough for thermal insulation to keep heat in or out between cycles, helping your system to work less to overcome the temperature of your ducts. The duct system is also prone to leaks at the joints. Any air leaked out means your system will take longer to provide adequate cold or hot air in your home. Insulation seals these leaks, increasing airflow through your system and further the efficiency of your HVAC system. By lessening heat transfer and leaks, you will significantly improve your system’s performance. Your system will also have to work less to achieve your desired temperatures, reducing wear and tears, which in turn saves you money from frequent repair bills. Increased energy efficiency will also reduce your energy bills, saving you money.
