I m in sacramento and in spite of our hot weather reputation it is primarily a heating climate.
Hvac ductwork in attic.
Here s why that is a good thing.
Why is condensation on ductwork a problem.
The really bad news is that with old metal duct systems the only option is replacement of the ducts to stop the rain in the attic.
Most of the commentary is about cooling but what about heating.
Sometimes air conditioned air will seep right through your ducts and become useless instead of heating and cooling your home.
Attic hvac systems also require shorter ducts.
Runs that are too long.
I vote for the attic.
All ducts are at risk for this type of leakage.
So why put an hvac system up in the attic at all.
Attic hvac systems save space.
If you have central heating and or air conditioning in your home the warm or cool air is delivered to each room through a system of connected ducts and vents.
That may require long runs of ductwork that make it hard for your hvac system to move conditioned air to certain areas within the space.
I agree that central hvac ducts in the attic are ridiculous.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
Choosing the right ductwork for installing in your attic as with.
Well mainly it s a way to save space.
Recently i had another hvac company come out and put in a new bathroom vent and they told me they believed the duct work was full of water.
Insulate and air seal the floor with open cell foam put ductwork and mechanicals in the attic install a radiant barrier and mastic seal the ducts.
When i look in my attic i wonder if a lot of the ductwork couldn.
The next most typical type of duct systems is made of flexible duct.
Again i d suggest calling an experienced hvac pro to guarantee your ducts are installed in your attic with proper support.
So water is condensing on your ac ducts.
Ductwork design mistake 2.
When the location of hvac equipment and duct system and not optimized in the planning phase the equipment may end up far away from the space to be cooled.
The attic ductwork is flex duct work.
It was new when the ac was put in 7 years ago.
Duct leakage causes a lot of problems including less.
Why is this a problem.
Flexible duct is a plastic tube that is reinforced with wire and then insulated on the outside.
When water condenses and drips into your attic or home it can cause a some serious secondary problems.
First water dripping off of your ducts and onto your insulation can cause the insulation to compress which decreases it s r value or ability to insulate.
Flex ducts themselves do not sweat however if the.
This is my climate i see ductwork in crawl spaces a lot and lots of problems.
Knowing the disadvantages of attic install and the crawl space install.
I called out the original hvac company and they took a look and said they saw no water.
Improperly supported flex ducts will sag which cuts down on airflow meaning cool air generated by an ac unit will struggle to reach your in law suite.
Retrofitting my house would be expensive and disruptive.
