Do you have one room in the house that's really cold? How do you fix it? Let's talk about it.
Welcome to Foam University. Today we're going to be talking about a topic that we get asked about a
lot, and that is if you have one room in the house that's very, very cold. The reality is this can be
kind of complicated and there's a few things you should be sure to investigate in. Those things are
HVAC, insulation and leaks. Before we dive into this, please go below hit that thumbs up button for us,
thanks. So let's go over how your HVAC system can be making one room really cold. Well one thing
that we see quite often is, we'll get a call and someone will say that they have an upstairs room
that's super cold and we'll go out and check out everything, and come to find out there's no
heat register going to that room at all. That means there's no heat from the furnace actually reaching
that room. Kind of this can be a simple fix in a way. All you have to do in some cases is just
have a heat line ran to that room. Now of course that can be very simple in some cases or it can be
super invasive in others. It all depends on your HVAC system and how your house is finished off.
For example if you have HVAC that runs through your attic, it could be pretty simple and not very
invasive at all to have a line ran to that room, but if it's ran through walls, then again you could
be opening up a lot of drywall, cutting into floors potentially. So keep in mind it could be invasive,
could not be. The point is how your HVAC system is ran, if there's registers to that room, if there's
any blockages, if there's air loss on the ducts, things like that, however that HVAC is potentially
not running efficiently can really cause one room to be cold. So that's the first thing I always
check out is the HVAC system. So now let's talk about the insulation. Now of course we talk about
insulation as retaining heat inside of a room, and we see this a lot if someone calls us and they say
they have one room that's just particularly colder than the rest of the house. You want to look at all
the outside walls. Because again if this room is not included in the building envelope your heat
could just be pouring out of here. So of course that internal temperature will not stay high.
So you want to look at the top, you only look at the attic area, the ceiling, what's in there as
far as insulation? Is it providing an air seal? You want to do the same for the walls and the floor.
Basically you want to look at this room just like you would a house as a whole. Make sure all outside
penetrations are as sealed up as they possibly can be, and again once you have that heat source coming
in, you want to make sure that insulation is around the outside, making sure it stays in. Again this is
why something like foam works so well, because it establishes that building envelope. So the last
thing that we want to touch on is any potential leaks inside this cold room of yours. Now of course
this can be doors and windows, just letting air in and out. That of course can cause a lot of problems
and make that room really cold, but we're also talking about leaks in the building envelope and
potentially the insulation. Again this is why we push foam so much and why we only use foam, because
it establishes that air seal. So if you have heat loss whether it's through doors and windows, other
penetrations on the outside, or that insulation is allowing that heat loss to come in and out,
or if something on the inside of the house, so if the interior walls, if that is pouring the heat in
or out again that can cause that room to be hot or cold. So make sure you pay attention to any leaks,
and again when we're looking at these rooms you want to look at it as a whole
system. Make sure you check out that HVAC, make sure you go over the installation, what's inside the
entire envelope, and make sure you check the entire space for any leaks so that they can get sealed up.
