The top floor apartment is the most coveted space to live on and it’s for all the right reasons. The heating bills are incredibly lower, you get less noise, and you have a beautiful view of the city. The only issue with the top-floor apartment is that it gets super hot in summer. Here’s a little 1st grade science recap; heat rises. When the temperature rises, the air gets less dense and it rises. The less-dense air floats on top of cool air.
There are other explanations for why the top-floor apartment is usually warmer than the lower units, like direct sun exposure and poor ventilation. Whatever causes your apartment to heat up during summer should be the least of your problems, especially after reading all the hints and tips we have provided in this article on how to keep your top-floor apartment cool in summer.
Why Top Floor Apartments Retain Warmth
The issue of top-floor apartments retaining more warmth than the lower units has been observed in different climate regions and here are the top reasons why;
Roof retains heat
Heat has a natural tendency to rise. When temperature increases, air expands and becomes less dense. The warm, less dense air rises and floats on top of cool, dense air. The heat from the lower apartments on your building will warm up and rise upwards.
The warm air accumulates on the top-floor surrounding before escaping outside. There’s a high chance that the interior of your unit will also get warmed up by this air.
This is pretty obvious. More sun exposure makes your apartment retain more warmth than the lower units. If your ceiling is directly connected to the building’s roof, then the heat from the sunlight will get transmitted into your unit.
Depending on the material your roof is made from, the experience can be worse. For instance, if the roof is dark-colored, it will absorb more sunlight compared to a light-colored roof.
The apartments on the lower floor have a lot less exposure to sunlight. Roofing materials have zero impact on the amount of heat they get.
If your unit has poor ventilation, then you are bound to suffer extremely high temperatures because the warm air that accumulates inside won’t have a way to escape. You have to optimize airflow in your poorly ventilated apartment to survive the dog days of summer.
Devices That Can Help
There are a couple of devices that you can invest in to help you keep your top-floor apartment cool like;
1. AC unit
This is the most popular device for controlling indoor temperatures. There are myriad types of AC units that you can get including; Portable AC, Ventless AC, and Window AC.
Portable AC – this is usually a prime choice for most people because it is super-easy to install and can be carried from one room to another with ease. They are a top preference for renters because of their portability and also most landlords approve them.
Most portable units are standalone units measuring about 24 inches in height and 18 inches in width. They are pretty compact and you can reposition them anytime to deliver cold air wherever you want. Most of them feature wheels that make them easily portable.
A portable AC is built with a hose on its back to exhaust the hot air it has captured outside. This means you have to attach the hose to a window that is about 6 inches open for it to blow out the hot air properly.
The exhaust hose comes in a slim easy-to-handle design that you can remove in a matter of seconds if you need to roll the AC to the next room.
Ventless AC – this is pretty similar to the portable AC, except it doesn’t need an open window for ventilation. Ventless ACs come in compact designs with wheel for easy portability. Therefore, you can use them anywhere in your apartment.
The units feature an internal tank and a big spinning fan blade. The internal tank is meant to be filled with water so that when the fan spins, little amount of water is misted into the air to cool it down.
Window ACs – This is the cheapest AC option. A window AC is installed inside a window sill and pumps cold air to the center of the room. It is a very simple system that you cannot manipulate once installed.
According to most reviews, the Frigidaire window air conditioner is the best that money can buy. It can effectively cool an area of up to 350sq ft, thus a perfect option for bedrooms. The best thing about it is it comes with a full-function remote control that allows you to control the speed and temperature from across the room.
Many landlords don’t allow renters to install window ACs in their apartments because some people find them unsightly. Also, some units tend to drip water out the back.
