Why Is My Bedroom Hotter Than the Rest of the House?

by

Your home is meant to be the most comfortable place for you and your family. You decide on each aspect, from the house layout and interior design to the light exposure and temperature.

Keeping your house cool in the summer is a necessity, especially if you live in a warmer climate.

However, there may be some rooms in your house which stay warm despite the air conditioning system. You may be wondering why that is.

Here are some reasons why your bedroom may be hotter than the rest of the house.

Unbalanced Air Conditioning System

All air conditioning or heating systems have ducts to transport the air to the entire house. Larger systems require longer and larger ducts and more supply vents for proper circulation.

These ducts have adjustable valves known as dampers, which can help you tune the airflow.

Proper duct installation and air balancing are crucial. Air balancing is the process of adjusting how much cool air or warm air reaches each room.

An unbalanced air conditioning or heating system can result in some areas of your house being warmer than others.

Various issues in these ducts or vents can result in variable room temperatures. Older systems and larger systems will have more problems. However, even newer systems can demand constant care and service.

Here are some of the most common reasons for inconsistent temperatures in your house:

Closed Vents and Open Windows

Inspecting whether your vents are closed in a particular room can help you understand why that room is warmer. Closed vents stop the cool air from reaching that room or area of your house. Therefore there is less air circulation.

Make sure that the vents in your room are not being blocked by any furniture or wall decorations. Not only does this affect the room’s temperature, but it could cause an imbalance in the entire system.

Alternatively, you could open all the doors in your house to allow the cool air to reach every corner. Cracked or opened windows could also contribute to the cool air leaving the room and causing the temperature to rise.

Inadequately Insulated Ducts

Uninsulated ducts cannot efficiently maintain the temperature of the air that flows through them. The air ducts pass through unconditioned areas of your house, where they gain heat. This results in warm air reaching some parts of the house.

Large air conditioning systems have longer air ducts, which can get heated up if not insulated properly. Longer air ducts may need reconstruction to provide better airflow. Older homes tend to have this issue.

If improper insulation is allowing heat to enter your home, the cool air will always escape. No matter how efficient your air conditioner system is, it will ultimately be ineffective.

Large Air Conditioning Systems

Larger systems work faster to reach the setpoint temperature fixed in the thermostat. This leads them to shut down once the point is detected and start-up when there is a change in temperature.

Frequent power surges can result in higher energy bills and the wear and tear of the system.

If you have a larger air conditioning system installed, it may have become worn down. They typically have a short life span and can rack up a high operational cost.

Additionally, larger systems normally have longer air ducts, which can take time to transport cool air. It may result in some rooms in your house not receiving sufficient cool air. Another option is for you to install ceiling fans to circulate the cool air to the warmer areas of your house.

Smaller Air Conditioning Systems

Smaller systems have a lower cooling capacity. If you have a small air conditioning system installed, it may be insufficient in providing enough cool air for your entire house.

You might need to install an additional system to cool the warmer rooms.

Typically, air conditioner systems are fitted according to your house’s layout. But the smaller air ducts cannot always provide cool air to every single room.

Therefore, you could reconsider a proper air condition system size to meet your house’s needs.

Clogged Air Ducts and Dirty Air Filters

Over time, debris such as dust, dirt, hair, and other materials, can build up in the air ducts. Airflow can become restricted and therefore affect the amount of cool air that reaches you.

Ducts are designed to be the perfect size to deliver you the exact amount of heating or cooling that you need. Anything obstructing this flow can make a significant difference in the temperature.

Regularly cleaning out and servicing your air conditioning system can help prevent this and provide unobstructed cool air. It is recommended to have your system checked by a professional at least once or twice a year.

Leaky or Damaged Air Ducts

If your conditioned air is leaking from the ducts, it could explain why some rooms seem to receive less cooling. Similarly, damaged pipes or air ducts will also reduce the efficiency of airflow in your house.

To check whether you have a leak, open the inside door are look at the hinges. A black dust trail is a clear indicator of a leaky duct. They can cause drafts, uneven temperatures, and even higher energy bills.

Contacting a certified technician or an HVAC professional can help you identify and fix the leak or make the necessary repairs. This will allow you to finally have a consistent home temperature.

Lack of Return Air Vents

Proper air circulation is very important in a centrally air-conditioned house. The return vents are meant to suck the warm air away from the specific room. Then, the supply vents replace it with cool air.

You can add more return vents to the room, which makes it stays warmer. This will make a great improvement in maintaining a cooler temperature.

Other Reasons Your Room Bedroom May Be Hotter

The aforementioned issues are related to your air conditioning system and air ducts. However, there are other factors you should consider, as well.

Inconsistent Temperature in Multi-Level Houses

Multiple story houses can tend to have issues with maintaining a single temperature. The hotter air rises, therefore the higher levels become warmer faster.

Coupled with more exposure to sunlight through the roof, the rooms on your top floor may take longer to cool.

One way to combat this is to use zoning systems. These zoning air conditioning systems break up your house into different areas. A thermostat or temperature sensor is fitted into each zone to monitor the temperature of that specific area.

The system can adjust the dampers in the air ducts to control the airflow. Therefore, you can have an even temperature throughout your house.

Identifying How the Room is Being Used

It is a well-known fact that electronic devices generate heat. So, home offices or gaming rooms can tend to be warmer than the rest of the house. The computer, servers, PCs, consoles, and other devices need a cool environment to function properly.

Moreover, a room which has more ill-fitted windows might be warmer. If it receives more sunlight during the day, it will heat up faster. You can use curtains or blinds to reduce the amount of sunlight that enters the room.

Hence, if you are using that room for activities that produce heat, it will require more airflow. These can include exercise, baking, video shoots, and more.

Your air conditioner company can assist you in adjusting the dampers. This will allow for more cool air to enter the room.

You Have Recently Had Home Renovations Done

Construction work and home renovations can upset the air balance. This applies particularly if you have had walls built or demolished.

The thermostats are fitted according to the heat load of the area. A larger area will have more heat load and will need more cooling to reach the set point.

Furthermore, it is possible that air ducts or the air conditioner system got damaged during construction. Having it inspected can help you gain a clearer understanding of what the issue is.

Conclusion

An air conditioning system does more than just cool down and heat up your house. It acts as a de-humidifier, which can be very beneficial for people with respiratory issues.

A comfortable home temperature and humidity level are essential for you to feel at home. While warmer rooms are a common issue in most homes, there are ways to fix it.

A thorough analysis and inspection of your air conditioning system can put you at ease. The right professionals will recommend the best course of action for you.
