Why Does My Bedroom Get Cold? Temperatures Explained

There are several plausible reasons why your room could be too cold for your liking. Even if you spend the majority of your time in your bedroom, the low indoor temperatures can make you feel ill during the cold months. It is not always comfortable to be cold during sleeping.

So why is your bedroom always so cold? Why do you have to wear two hoodies and cover with a blanket just to get out of bed?

The walls of your bedroom are thinner than the rest of your house. Improper installation of ductwork could be another reason. Dirty air vents should also be checked since they could be causing your problem.

What are some other reasons that could be the root of your problem and how to fix them? We’ll tell you what you can do on your own and when to call in a professional. Don’t worry too much – most of these issues are easily fixed!

Why Is One Room Colder Than The Other?

Let’s start with the basic possibility. Pay attention to which cardinal directions your rooms face. If your bedroom gets extremely warm around noon and gets colder at night, your walls are probably thin enough to notice the external influences.

To alleviate the influences of outside temperatures you should make sure you keep your windows closed during extremely hot days and very cold nights. Invest in air condition if you can and it should be very helpful.

However, ductwork can be improperly installed, which is a problem on its own. Ducts or conduits are used in heating and ventilation. If they are not done properly, your air conditioning device can be working but it won’t be very helpful.

If you want to replace or install your ductwork, you should at least consult with an expert since ductwork is related to your other rooms and this can make your DIY job very difficult. 

The amount of money you need to save to get ductwork replaced goes from $300 to $550, depending on how much work needs to be done to fix the problem.

Sometimes your filter on the air conditioner device can get dirty or smelly. You will need to clean the filter from dust. If you don’t your device may stop working properly and you will have to pay a lot more to get it fixed, cleaned, or simply buy a new one.

Why Is Your Bedroom Cold When The Heat Is On?

Dirty filters or old cooling devices can cause your room to get too cold or too warm even when they are on. If you are not sure if this is your problem, try and see how strong the airflow is when the device is working on the maximum. 

Make sure you clean the filters every few weeks if your device is older than 5 years. You can do it more often, it will not do you any harm.

Ductwork needs to be insulated and if there are not enough or there are too many vents, your room will stay cold even when the heat is on. 

If your house is old and you haven’t replaced the walls or vents, this could also be causing this issue. Old houses have thicker walls and rarely have weatherproof wall coating. The exterior could have been ignored for a long time which means your heater needs to work twice as hard just to maintain a normal temperature inside.

Inspect the heating vents and thermostat readings. Blocking or covering vents with large furniture like couches or beds lets the heat you pay for be absorbed into upholstery, leaving the room cold. So pay attention to that as well.

Why Are Your Bedroom Walls So Cold?

How many times has this scenario happened to you in your own home: you want to lean against a wall and you feel like you leaned against an ice cube? Your walls are so cold you can feel them through your sweater.

Or maybe you accidentally brushed against a wall or stopped yourself from falling over legos in your kid’s room and got shocked by the cold wall? Maybe you even got used to it and don’t mind it anymore. We are here to tell you you shouldn’t settle for this – it is not as normal as you originally thought.

Insufficient insulation is the villain in this story. If your walls are not properly insulated, the heat in your home quickly disperses and gets out instead of staying in your room. They should be insulated so that the walls act as barriers protecting you from the outside temperatures and also keeping your heat trapped inside of your home.

A slightly chilly wall that doesn’t affect you too much is unlikely to be a big problem. It will ultimately affect your energy bill in the long term.

Around 30% of the heat you paid for isn’t doing its job. Instead, it gets out. If you have walls that have damp or cold to the touch and you want to make them warmer, the easy answer to this is to insulate.

However, if insulation is not a possibility, or not quite doing the job, make sure you have proper ventilation because it can help remove the moisture from a room and keep the walls dry. The last thing you want is unnecessary moisture and mold on your walls.

How Do You Find Out Why Your Bedroom Is Cold?

It is pretty simple. You will need to get information from a previous owner or contact a professional and have them look at the ventilation, ductwork, and outside of the walls. 

If a cold bedroom is a new problem that appeared seemingly out of nowhere it is probably due to ventilation failing or your air conditioner being too old or in a rough state. Think about how long you have had these issues and if something else has changed in your home.

If you have had some work done around your walls, your vents could be damaged or your ductwork leaky. If this is the case, contact the person who was responsible for your projects and ask them about the possibilities. 

They should be able to give you some information as well as at least check if something went wrong – maybe even fix it for free if it was their fault. There is another temporary solution. You can accomplish this by buying some mastic sealant or HVAC tape yourself and attempting to patch the holes.

Considering the time and the amount of work that goes into fixing or replacing ductwork, you may decide on this option if the situation is not critical and just requires a quick fix.

How To Make Your Bedroom Warmer?

There are several ways you can make your bedroom warmer. Here is a shortlist of the things you can do to make yourself as comfortable (and warm) as possible without much effort.

  1. Check for drafts. Light a candle or some incense to check if your windows or doors have any leaks. Weatherstrip is a great solution when it comes to drafts and leaks.

  1. Invest in warm bedding. There are specific materials for sheets and pillowcases that will keep you warmer. Merino wool is one of the best materials for such rooms. Wool keeps its heat. 

The more body heat you produce, the more heat will be provided to you. Even if you are using wool during hot summer days, it will not make you too warm – it will create a barrier to protect your body from heat and it will stay a normal temperature, unlike other blankets.

  1. Move your bed away from the window. You may have noticed the walls are colder around the window. It may have some leaks and when you open it the cold air will swallow your bed making it seem like an ice cave.
