Townhouse Air Conditioner In Attic Gets Too Hot

Here is what the winter stack effect looks like.

Townhouse air conditioner in attic gets too hot.

In order to let air out other air has to come in. The natural rise of heated air. If your upstairs is 80 and it is 95 outside you are increasing the temp by opening a window not decreasing it. It s a thermodynamic principle that hot air will rise in order to try and escape an enclosed space like your home.

Let the hot air escape. Note the air escaping through recessed lights the attic hatch and so forth. When the attic and attic access are not properly sealed and insulated the hot air coming in through the roof can leak into the lower floors of the home. Open a window on the top floor.

From the boiler the water gets pumped through a network of tubes set. Even with the central air conditioner running on full blast it seems like the top level of a home never gets as cold as the rest of the house. If you want to know how to keep upstairs cool and not blazing hot during the summer this guide can help. In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth.

Suck cool air conditioned air into the attic and of course it won t be so hot. Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer. It wants to move. If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage.

Fortunately there are a few things you can try. But then you still have a really crappy house. It wants to move. Since hot air rises the rooms upstairs in your home will likely be much warmer than those on the lower level.

It is called reverse stack effect in summer. An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate. And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature. Installing a thermostat on both floors can help the cooling system detect which areas in your home are too hot or just right so only the necessary amount of energy is used to keep you cool.

Combine this with the hot air rising from the lower floors and you re looking at a perfect recipe for uncomfortable upstairs environments. When your ac unit starts pumping cool air into your townhouse warmer air in the space is going to quickly try to make it s way to the highest point it can find. Install vent less air conditioning units. Don t do this if you live somewhere that actually gets hot.

An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be.
