Fiberglass air duct insulation

Consider Fiberglass Air Duct Insulation

If you take a minute to look in the unfinished parts of your basement you may see large metal ducting hanging there. Those ducts are what carry the cool air through your house in the summer from your air conditioning unit to the places where people spend time. Those ducts can also be a major source of loss of efficiency in your HVAC system. Going the extra mile and putting fiberglass insulation over your ducting can improve the comfort levels in your home as well as help to reduce energy bills in the hot summer months.

Reduce Background Noise

One of the first things you might notice if you have your ducting insulated is that the noise from your HVAC unit is reduced. Since ducting is metal it can carry sounds very easily. This means that any noises that your HVAC unit makes when operating, such as fan noises that can be generated by the system that moves the air through the ducts and even voices from other rooms, can all be carried through ducting. Fiberglass insulation helps to dampen out these sounds and can reduce background noise in your home significantly.

Elevated Comfort Levels

Your air conditioner cools the air and then blows the it through your home using fans and the ducting for transport. Ducting that has no insulation on it is not as effective at keeping the temperature of that air constant. As the air is moved through the ducting more of the heat of the rooms the air moves through creeps in and heats it up. By putting insulation over your ducting your losses due to heat from outside of the ducts will be reduced, meaning the cool air goes where you want it to: your living space.

Conserving Energy

An HVAC system is a complex machine. It does the work of taking the ambient temperature air in and then puts it through a cooling process. Once that is done it blows the air through your home via your ducts to the rooms that you want cooled. The whole process takes energy. If your ducts are not insulated, then some of that cooling power is lost as the air is circulated through your home. This means the system has to run longer to match the temperature at which you set the thermostat. It also means the pumps, fans and coolers must work longer as well. Insulated ducting will cause your home to be cooled more efficiently and will reduce the amount of energy that it takes to hold your home at the desired temperature.

Lower Bills

With reduced energy demand comes a reduced costs in your energy bills. Improving the efficiency of your system by insulating the ducts will translate to savings for you at the end of the month when the bill comes in for operating your HVAC system.

Do I have leaky ducts?

Do You Have Leaky Ducts?

No, we aren’t asking if you are prone to tears at Long Distance commercials or movies on a certain network. We’re referring to the ducts that exist in your walls and floor that carry all the cool air your central AC unit manufactures to your room.

The ductwork of your HVAC system is often forgotten because it is seldom seen and rarely heard from. The truth is ducting that isn’t sealed properly can have a huge effect on your HVAC system’s efficiency, air quality and ultimately your energy bills. Here are some ways that you can spot problems with your duct work.

Sudden or Gradual Rise in Cooling Bills

Have you noticed that your cooling bills have sharply risen recently? Maybe it has been a more gradual climb, but it’s definitely outpacing the rate at which general energy costs are rising. Either way, rising bills could be a sign that your ductwork is leaking.

Leaky ducts means that air that should be pumped into your rooms is escaping into the spaces between your walls or even out of your vents into the open air. Because of this, your system needs to work harder to reach and maintain the temperatures that you set it to.

Reduced Airflow at Your Vents

You may notice reduced air flow coming out of the vents into your room. If you find yourself thinking that the air should be blowing out more forcefully, or even if you notice one room blowing harder than the other, this could be an indication of a leaky duct. A leak means that instead of making to the vents into your room, air is leaking out into other spaces, reducing the flow that is doing the cooling. This reduction in flow is typically due to a sealing problem.

Odd Smells Coming from Vents in the Home

Unfortunately, a duct usually doesn’t decide to leak out into an open space that is easily accessible. Duct leaks typically occur in spaces that are dark and often damp. Because of this, leaks attract the growth of mold, bacteria and mildew. As these substances grow in the ductwork, they will be blown through your home during normal operation of your AC system. This leads to odd smells emanating from your vents.

If you notice odd smells from any of the vents, or even a new damp smell in your home, it could be due to leaking ductwork.

Effects of Leaking Ductwork

The most obvious effect is that your energy bills are going to go up. Leaks reduce the efficiency of your unit forcing it to work harder.

A secondary problem is that due to working harder, your AC unit is now being put under additional wear and tear. This means parts could wear out sooner than they should. Your entire unit might need replaced sooner than you expected.
