Why is My Room so Cold

Inconsistent temperatures in your home aren’t uncommon. Maybe your heater is on full blast but no matter how much you try your bedroom just won’t warm up. Having your heater not work ranges from annoying to dangerous but thankfully there are a few steps you can take to figure out why your room is cold and what you can do to fix it.

Air Filters

One reason why your rooms aren’t warming up is because of the air filters. If your filters are clogged and/or old then they won’t filter out the particles they’re supposed to and the air can’t flow properly. When the airflow is obstructed then your home is going to have difficulty heating up. Make sure you keep up with regular service on your filters and replace them every 6-12 months depending on if you have anything like animals that would add to the allergens in your home.

Also, if you notice that your filters seem to be falling into the return air vent opening which can restrict airflow to the house and cause inconsistent temperatures. If this is the case when you replace your filter look for a filter with a low MERV rating which allows for more air to pass through the home.

Important: As a homeowner, realizing that you need to waste another Saturday waiting for the landlord or handyman to come over to fix another damaged appliance is frustrating. It shouldn't feel like the norm to constantly have damaged appliances and systems in your home since it can come to a huge cost at the end of each year.

The Home Improvement Solutions eBook covers everything you need to do in your home when it comes to maintenance and improvement so you can avoid wasting another weekend waiting for someone to come to your rescue.  

Air Vents

Another thing that could be causing low temperatures in your rooms are the air vents. Air vents are scattered throughout your home and some rooms may have more than one depending on their size. It may be obvious but double-check that all your vents are open, if a vent is closed then heat isn’t flowing to that part of the home.

If you have large objects on top of your vents then the air flow can be blocked off. One thing to do would be to move any objects that are seated directly over and touching the vent because not only are you cutting off the heat but you’re possibly creating a safety hazard. Another thing to do with objects over the vents but aren’t touching is buy an air redirector (view on Amazon) in order to curve the air into the room from wherever it’s hidden right now. I use one under the dresser in my bedroom and it works like a charm

Leaky Ductwork

Leaky Ductwork can also result in certain rooms being colder than the rest of the house. You can usually tell this if you run your air conditioner for a long time but your home doesn’t cool down or your house is very humid. Also, if dust seems to accumulate more than usual this can be a sign because it isn’t being filtered out. Thankfully, it’s not hard to fix leaky ducts yourself.

For a permanent fix you’re going to want duct putty or if you’re okay with a temporary fix then you can use duct tape. You should wear a mask and you’re going to turn your heater on full blast, from there try to identify around the ducts anywhere heat is escaping. A good place to look is where two ducts leak together. Once you identify the problem areas and use your putty or tape to fix it up.

Insulation

The insulation in your home may be a huge reason as to why certain parts of the home may be colder than others. This becomes a big problem when you are trying to run your heater because with poor insulation your heat will just escape and you will waste money trying to heat up the home.

The good news is there are several things you can do to insulate your home, one of the easiest is to seal your doorways. There’s a high likelihood that there are spaces between your door and the frame which can lead to escape points for heat. All you need to do is buy new weather stripping and slide it onto the bottom and sides of the door to prevent drafts from coming in. Another thing you can do is add insulation to your windows.

Like doors, windows and create escape points for your heat through cracks or if you have double-pane windows. A quick DIY trick for this is to get plastic sheeting and use tape to attach it to your windows. You can use a hair dryer to blow on the sheets until they become taut and stick to the windows properly. It may not look the best but it’s a cheap way to keep your windows sealed better for the winter.

Windows

Windows play a large part in keeping parts of your home temperate and if your windows aren’t energy efficient (as most older homes don’t have) then the cold can stay trapped in your home. There are types of windows you can buy that would work better in keeping your home hotter in the winter (as well as cooler in the summer) as long as you have the time and money a full window installation would take. You could always use protective add-ons like weather strips, foam tape, new caulk, or insulated curtains then can help keep your house warmer. Thermal curtains are my favorite because they retain heat very well in the winter.

Home Renovations

If you have recently renovated your property with additional rooms you added on, then these new additions could be the reason why some of your rooms are colder than others. The heater in your home was designed for the original layout and when you add rooms on then it disrupts the flow. Make sure with new rooms you add in the ductwork necessary for heating the room during the cold months.

Thermostat

One thing that is a possible reason why your home is too cold is because the thermostat is heating to incorrect temperatures. When the heat is read wrong then getting the house to warm up can be difficult. One thing you can do is get a second thermostat and tape it to the wall next to your current one.

Leave it for fifteen minutes and see if it reads the same as the one installed in your home, if not then you’re going to have to get someone with electrical training to come take a look at it. This is very likely if your thermostat is quite old or brand new. Thermostats have to be changed over time to read accurately but a new thermostat could have been installed wrong and aren’t properly controlling your air ducts.

Fun fact! This happened to me in January and the house wouldn’t heat or cool down. If this is the case, get in contact with the company (or the landlord) to come and fix it sooner rather than later because a miswired thermostat can cost you with your company who controls your heating.

Time of Day

Perhaps when you’re colder in your house it’s during the mornings. It’s very common for people to feel cold when they wake up and it’s difficult to drag yourself out of bed to start your day. One reason for this may be because you’re not keeping your room at the ideal temperature. The World Health Organization (WHO) says that the ideal temperature you should have indoors is 18°C (~64°F).

Along those lines the best temperature for sleeping is between 15 – 20°C (~59 – 68°F) so if you keep your thermostat set to an ideal level then it shouldn’t be as hard to wake up in the morning. Some people may feel like their room is getting colder at night as well. This is generally caused by the positioning of the room in the house. If your room faces north or south then it generally tends to be a bit colder than rooms that have the sun beat on them directly during the day.

Bottom Line

Hopefully after reading you’ll know why your room isn’t heating right and you know not to be like me and don’t wait to get someone to come take a look if your thermostat isn’t working.
