Why Is My Bedroom So Cold? How to Make it Warmer!

Do you step inside your bedroom only to feel that it’s substantially colder than other rooms in your house?

Ideally, your bedroom should be at the same temperature as all the other rooms in your house.

If you have low temperatures in your bedroom, you could have a problem with your ductwork.

Nevertheless, there could be multiple other reasons why your bedroom could be too cold for your preference.

In this article, we will discuss why your bedroom is so cold and what you can do to fix it.

Why Is My Bedroom So Cold?

Sleeping in a cold bedroom can be quite an uncomfortable experience. Plus, the low temperatures can even make you feel sick during the winter months.

So why is your bedroom so cold?

Why do you need to wear two hoodies and cover yourself with a blanket only to get out of bed? Let’s find out.

Thin Walls

Let us begin with the simplest possibility. Pay attention to which cardinal direction your bedroom faces.

If your bedroom gets warm in the afternoon and cold at night, your walls are perhaps thin enough to get affected by the outside temperature.

To reduce the external influences, you should close your windows on extremely cold nights.

Blocked Vents

Another reason for a cold bedroom could be blocked vents. Thus, you should inspect all of the heating vents around your bedroom.

In certain cases, a furniture item might be obstructing the vent.

If that’s the case, move the furniture out of the way and rearrange the room, if necessary. You should also do the following things:

  • Check the outer grates for signs of gunk buildup or dust.
  • Clean the grates if they are dirty.
  • If the grates look clean, remove the duct cover to check the inner vent.

You should also check if the vent is closed. For example, if you have recently moved into a new home, the vents can get closed.

If the vent is closed, the air in the ductwork will go elsewhere in your home.

The problem could also be dirt lines on the inner vent.

If you spot a rodent carcass or rodent dropping, you have an infestation issue and should immediately get in touch with an exterminator.

Make sure you take a flashlight to the vents to inspect them more closely.

You can even get a better idea about the condition of your vents by reaching inside and taking pictures with your phone.

Dirty Filters and Air Vents

A dirty HVAC system can also be the culprit behind cold bedrooms. Your air vents and filters might be immensely dirty.

Learn about your HVAC system to know what the manufacturer says about replacing the filter. It is generally replaced every month.

This is particularly true if there’s high traffic passing through your home and if it’s allergy season.

It’s also an excellent idea to periodically clean the ducts and consider occasional HVAC preventative maintenance to avoid poor airflow.

To clean up the air vents, you should follow these steps:

  • Turn off your HVAC system and detach the duct covers from the walls.
  • Thoroughly clean up the grates of every grate. You can use a cleaning spray or soapy water too in this step.
  • Use a vacuum hose to remove the dust from the air ducts. Make sure to also vacuum over any crevices.

Follow the same steps to clean out the grates on your ceiling.

During the cleanup, make sure to wear a dust mask and cover the floor with old newspaper. This will prevent the dust from landing on your face or the floor.

Drafty Windows

If there are cold drafts or winds around your windows, it means that heat is escaping. Even if there aren’t any cold drafts, there might be a leakage of air around your windows.

Check around every window frame for gaps and cracks or rotting wood, deteriorating caulking, and missing or cracked glass.

If you have single-pane windows, you might have to replace them. Upgrading to double-pane windows can even reduce your heating bill in winter.

Leakages in Your Ductwork

If your bedroom is cold at night but hot during the day, your ductwork is likely leaking.

Leakages in the ductwork can happen due to regular wear and tear or occur naturally from your house settling. Even pets bumping into the ductwork can cause leakages.

The problem can also be improper sealing of your ductwork. The leaking ductwork interrupts the flow of air.

Thus, you won’t get sufficient air into each room in your house, resulting in warm or cold rooms.

In case the cause of your cold bedroom is leaking ductwork, you need to hire an HVAC professional who can inspect and check the issue.

A professional HVAC professional can investigate your ductwork and identify leaks effectively.

If the ductwork is indeed leaking, the professional can repair it in a short time. They will even be able to discover any other problems that might be going on with your system.

Uninsulated Ductwork and Walls

Ductwork has to be properly insulated. If there are too many or too few vents, your bedroom will remain cold even when your heater is switched on.

You could invest in new insulation or restuff the wall cavities. However, you will have to remove the interior plasterboard to perform this task.

The simplest method to re-insulate your walls is to spray foam insulation inside the wall cavities.

Spray foam insulation enlarges to fill tiny gaps and enclosed spaces. You can apply foam insulation inside each wall cavity through tiny holes in your walls.

Most spray foam insulation is non-intrusive substances that can easily be cut away when needed.

If you live in an old house and haven’t replaced the vents or walls, this could also be causing the problem.

Old houses have thick walls and seldom have weatherproof wall coating.

As a result, the exterior could’ve been neglected for a long period which means your heater might not be able to increase the temperature.

How Do You Determine Why Your Bathroom Is So Cold?

It’s quite easy. You will need to speak to the previous owner or consult a professional and have them check the ductwork, ventilation, and exterior of the walls.

In case the cold bedroom is a new issue, it is perhaps because of failing ventilation or an improperly functioning air conditioner.

Think about how long you’ve had such problems and if something else has changed in your house.

For example, getting some work done around your walls can damage your vents or introduce leaks in your ductwork.

If that’s the case, contact the contractor and discuss the possibilities with them.

They might be able to offer some valuable information. Plus, they might also inspect if something went wrong and even repair it for free if it was their mistake.

There’s another makeshift solution for this problem. You can buy some HVAC tape or mastic sealant yourself and try to cover up the holes.

Given the time and effort needed to repair or replace ductwork, you can go with this solution if the problem isn’t critical and simply needs a quick fix.

How to Make Your Bedroom Warmer?

There are plenty of ways to make your bedroom warmer.

Here is a list of the things you can do to make the temperature inside your room comfortable without investing too much effort.

Change the Direction of Your Ceiling Fan

To increase the temperature in your bedroom, you can reverse your fan’s motor and make it clockwise.

This way, the fan creates an updraft that pushes the warm air near the ceiling back down and helps you feel warmer.

Use Draft Stoppers on Your Doors

One way to keep your bedroom warm is to use draft stoppers on your room. This prevents the cold air from entering the room.

You can even make your own draft stopper that matches your room décor.

Try A Space Heater

You can warm your bedroom a bit without switching on the central heat by using a space heater.

Make sure you pick a portable heater that’s appropriately sized for your bedroom. And place it far from the bed, so there’s no chance of the bedding coming in contact with it.

You should also practice safety precautions with the cord. For example, don’t stretch it across your bedroom escape route in case of an emergency.

Also, you need to ensure that the heater has a safety feature that switches it off automatically if it overheats or tips over.

Cover Your Floor with A Rug

Cover the floor of your bedroom with a thick rug during the winter months to insulate your bedroom.

A faux sheepskin rug doesn’t just look stylish but also adds a degree of warmth to the floor.

By now, you will have a fair idea of the reason behind your cold bedroom.
