The thermal mass retention, or bedroom heat buildup, is caused by structural components like exterior walls, thermal window glass, attic insulation, etc Basically, your home is a massive battery that is storing intense heat. As the outside temperature cools, they start releasing heat inward. If your bedroom is situated on the upper stories, then it will turn into a furnace. Gone is comfort, non-existent is asleep.

Why Is Your Bedroom So Hot at Night?

As summer approaches, you will find yourself asking, "why is my bedroom hot at night?" There are so many factors. Here are some of them.

Thermal Mass Retention: If your house is made mainly of bricks and cuts of an attic, then you are going to be boiling in the summer. These absorb the daytime sunlight and heat generated and radiate it downward into bedrooms all night long. Not even an open window can cool the temperature inside the room.

Stagnant Airflow: Having one window is the worst thing ever. To deal with the rigorous summers after a heavy winter, you must have at least 2 windows to allow for ventilation. A single window bedroom will only lock the heat inside.

Internal heat accumulation: Often, using highly powered electronics or bright lights adds to the already existing natural heat. Not to forget the continuously generating natural metabolic body heat in enclosed spaces. A combination of these factors automatically increases the temperature inside your room.

Weather: Solar radiation is the highest in the peak afternoon hours. If you live in a cold region that has massive insulation in the ceiling, then in the summer, this could be a very massive disadvantage. You are essentially barbecue, long after sundown, during the hotter months.

Architecture: Quite commonly, the layout of your house restricts the air flow. Quite a few HVAC systems suffer from imbalanced duct layouts. Central air distribution often sees air taking longer to reach your bedroom.  

Daily domestic habits: Your bedroom setup and daily domestic habits also contribute to internal heat. Things like flat screen televisions, gaming consoles, computers, etc. Also, add to the heat. In addition, you also have the metabolic heat generated from two sleeping adults in the room. Add some pets, and you get like a fully functional furnace. The ambient temperature can easily climb several degrees just by this. 

What Options Should You Explore?

The first step towards keeping your room and how school is recognizing the diverse environmental factors. It is a good thing that the modern marketplace offers you options for bedroom cooling with air conditioner setups. You can get anything from fast and temporary to permanent and quiet.

Direct Feature Comparison

To help you choose the right system for your space, here is a quick breakdown of how these three popular bedroom options compare across key categories:

How to Choose the Right Air Conditioner for Your Bedroom?

No matter how many options are out there, it all boils down to how you choose it. Of course, this means that you have to take a balanced approach. Make a checklist of spatial measurements, acoustic engineering and energy-efficiency ratings. A blind purchase will only lead to disappointment. The most common method is going by the BTU, or British thermal unit. This will ensure that you get the correct amount of cooling.

Bedroom Air Conditioner Size Guide (BTUs)

This bedroom air conditioner size guide gives you the math on units required per square foot.

Pro Tip: If you live in a loft or bedroom with high ceilings, then increase your calculated cooling capacity by 10%. The same goes for a wall shared with a hot kitchen or an unshaded area receiving direct afternoon sunlight.

Target an Air Conditioner for a Small Bedroom Efficiency

Remember, energy efficiency comes above all else. And energy star certification or a high SEER/EER rating is vital to a problem-free cooling solution. Make sure your unit has eco-conscious refrigerants and variable inverter motors. They prevent massive spice and electricity consumption and save you money. After all, you want to keep your bedroom cooling costs as low as possible.

Insist on a Quiet Air Conditioner for Sleeping

Another key factor that is influential in selecting the best cooling solutions is the noise. Imagine a loud compressor clicking on and off while you sleep. It can be disruptive and even worse than a hot room. Start by verifying the decibel ratings on the product specifications. Any units that operate between 20DB and 50DB should give you a peaceful environment. For context, here’s a reference table.

Supplementary Ways to Keep a Bedroom Cool

As a homeowner, you do not want to overload your equipment. Most importantly, you don’t want to expand the budget. The crucial first step is to manage the radiating solar energy that streams through the windows. Here are some indoor cooling strategies in the absence of air conditioning.

Optimize Air Circulation

Despite its study and air conditioner, there could be pockets of your room with stagnant air. You need to get the circulation going to maintain a uniform temperature. Here’s what you should do.

• Ceiling fan: Here’s a tip. Enjoyed your ceiling fan moves counter-clockwise at a medium to high speed. The resulting downward breeze produces a chill effect on the skin and drops the temperature of the room.
• Cross-Breeze Set-Up: In areas where the evening temperature is lower than the indoor temperature, use an oscillating fan in front of an open window. If you have a second window, then open that to let the trapped hot air escape.
• Boosting the AC Boost: To distribute the chilled air across the flow and room much faster, place a small fan directly below, beneath or across from your window or portable AC unit.

Blackout Curtains

The first step towards heat buildup is to stop thermal energy from entering your room. Here’s how to protect against it.

• Thermal Insulation: Hang heavy-duty blackout curtains, solar shades or window films to block out 99% of radiant sunlight.
• Daytime Management: Keep your curtains completely closed during daylight hours.

Summer-Friendly Bedding

Very few people realize that their mattress and bed sheets can influence body heat retention. Here are some changes that you can make.

• Fabrics: Ditch that polyester microfiber, etc. Instead, use linen, organic bamboo or cotton.
• Get cooling bedding: Use a cooling gel mattress topper or a specialized cooling pillow. They pull away heat from your head and body throughout the night. 

Nighttime Routine Changes

Make these adjustments to your nighttime routine and notice the changes.

• Remove electronics: Your television screen, computers, etc. Can generate ambient heat. Turn them off and unplug them.
• Manage residual indoor heat: Use oven, clothes dryers and dishwashers only in the morning. Evening users can result in residual heat and drift down and rise in bedrooms.
• Take a warm shower: Cold showers can result in constriction of blood vessels, which indicates that your body should increase its core temperature. Lukewarm water instead relaxes your body and triggers an internal cooling response. 

Common Bedroom Cooling Mistakes to Avoid

The key to a good cold room is to consider the air conditioner efficiency. You definitely do not want to be racking up bills. You also don’t want to spend money fixing your AC constantly. Here are some common mistakes that you can avoid.

Choosing the wrong BTUs – Oversizing for a small room will rack up the bills. Under sizing will not cool the room enough. An imbalanced cooling cycle will either leave your room cold and damp or maintain the heat. The easy fix is to match the square footage with the exact recommended BTU output.

Neglecting filter maintenance – Air conditioners scrub dust, pet dander and allergens out of your indoor environment. This also means that it can clog the air filter, blocking air flow, and consuming more electricity. You’re now left with frozen evaporator coils. Fix this by cleaning the air conditioner filters every two to three weeks during peak summer. Quite a few units have washable mesh filters. Just do an easy rinse under the tap and air dry in minutes.

Allowing unsealed gaps – Seal your bedroom properly if you want to cool the air inside. Tiny gaps can affect your compressor. Loose connections in a portable AC can exhaust the hose and allow hot, humid air to seep back inside. Opt for high-density foam, weather stripping or acrylic window seals to insulate your AC installation.

Lowering the thermostat – Lowering the AC temperature will not make your bedroom cool faster. AC pumps out cold air at the same velocity regardless of the target temperature. If you do this, it will only cause you to increase your budget and also wake you up shivering in the middle of the night. It is more feasible to set your ideal best temperature for sleeping. An even better option is to opt for the sleep mode.

Running the AC 24/7 – Many of you will ignore zone control. Leaving your cooling system running all day is highly inefficient. Your appliance will run faster and save a reasonable amount of energy. Adopt programmable timers in Wi-Fi-enabled smart settings.

Summer brings about heat waves and interrupted sleep. A great cooling solution can provide you with hot weather home comfort. There are so many options to choose from. You’ve got the temporary portable unit that can cool any specific area. For an apartment setup, you can go for the window AC. As a large homeowner, you can depend upon a permanent ductless mini-split system. The key is to select the right equipment for your space. Besides this, all you need is cooling capacity, low noise level and high energy efficiency.

An Air Conditioner can change the way you live and function. Humans are creatures of comfort, so why not indulge a little? Make your lives easy and sleep well.
