The Significance Of Adequate Air Duct Insulation
Many people don't know that a poorly-insulated air duct is just as dangerous as a leaking air duct. Below are some of the problems your HVAC (heating, ventilation, and air conditioning) might experience if you don't insulate the air ducts.
Heating and Cooling Efficiency
Inadequate insulation allows the external environment to affect the temperature of the air inside the ducts. During the cold season, when you need to heat your house, your air ducts can cool and end up not heating your house properly. During the warm season, when you need to cool your house, the air ducts can heat up and end up not cooling your home.
Such external effects will leave your home in uncomfortable temperatures since the HVAC will be struggling to meet the demand. You might even experience uneven heating and cooling since some parts of the house might fail to get adequate conditioned air.
The HVAC system runs until the house reaches the temperature set on the thermostat. Once the temperatures match, the HVAC cycles off and only starts cooling or heating once the house temperature begins to fall. Such off and on cycling ensures comfortable temperatures with minimal energy consumption.
Unfortunately, that might not be the case if the air ducts don't have adequate insulation. Due to impaired heating and cooling, the HVAC will need to run for longer periods to heat or cool your house. The lengthy runtimes will lead to higher than normal energy consumption.
Inadequate insulation can also lead to condensation on the outside surfaces of the air ducts. The problem can arise during the summer season. The air ducts carry cool air during the summer season, and the air is full of moisture during this period. The moisture in the air might condense when it meets the cold surfaces of the duct materials.
Unfortunately, many air ducts are made of metal. The condensation can cause corrosion of the metal, which can lead to cracks or holes. The holes will cause leakages and contamination of the air ducts.
The rush of air through the duct can trigger duct noises. The expansion or contraction of air duct materials can also cause air duct noises due to temperature changes. Duct noises can be bothersome irrespective of their origin. Adequate duct insulation will absorb some of the noises so that they don't reach your indoor spaces.
Check the insulation on the air ducts regularly. Fix areas with inadequate insulation to continue enjoying efficient heating and cooling.
