I called out the original hvac company and they took a look and said they saw no water.
Forced air ductwork routed in attic.
Hvac ductwork in floor slabs.
If you don t have forced air the fan and coil system is typically placed in the attic where it will deliver cool air through ducts.
Where ductwork must be routed through unconditioned zones that experience temperature extremes such as the attic crawl space or basement reduce thermal loss by insulating affected spans.
Don t let a contractor talk you into it.
Duct delivers fresh air and humidification into your home.
In my experience heating ducts that run through attics cause serious problems in snow country.
Ducts that are in a ceiling tend to be a little more effective in distributing cooled air throughout a room.
Ductwork is the channel through which the air in your home is filtered and purified or expelled to the outdoors and replaced with fresh new air.
This article describes heating and air conditioning ducts that have been placed in or beneath concrete floor slabs.
The reality however is actually quite different.
Unfortunately this practice is all too common in our northern cold climate putting air conditioning ducts in the hottest.
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.
Hvac air ducts located inside concrete slab floors invite a surprisingly broad range of building problems that fall into two broad categories.
It was new when the ac was put in 7 years ago.
Since most homes have their hvac system serve multiple functions at once it can be cheaper to install the unit in the attic because the roof access can make inspections.
Comparing this configuration to a solar water heater they make the case that putting air conditioning ducts in a hot attic is an effective way to heat up the conditioned air as it travels from the air handler to the conditioned space inside the home.
Keep as much of the ductwork span as possible inside the conditioned envelope of the home.
If your ductwork is breaking down under the slab a coating is not going to do you.
Verify that ducts outside the conditioned zone are properly sealed.
In warm climates it is common practice to run heating and air conditioning ducting through attic spaces simply because it is easy to do.
Functional troubles such as lack of air flow or collapsed ductwork and environmental problems such as.
Heat pumps and ducts are part of it too.
Visions of walls torn open to install new ducts and a lengthy disruptive construction project can be daunting.
The attic ductwork is flex duct work.
A basement is below and.
A delivery system for all forced air systems furnace or air handler heating or air conditioning or both.
The 20 to 30 foot long pipes that carry the refrigerant are disguised to look like a downspout.
