Why Is My Room So Cold? How to Fix a Cold Room

Are you a homeowner who’s wondering why an entire room in your house is always cold? It may just be a chilling draft or a long freezing night, but once you’ve experienced unbearable coldness in the comfort of your own home, you’ll quickly realize that this is not a problem you want in the dead of winter.

There are several reasons your room is getting colder than it should in the winter. Let’s take a look at the most likely reasons.

Common Reasons Your Room Might Be Cold

How to Test Ductwork or Blocked Vents

Poorly installed or broken ductwork can cause you to have severely cold days and even colder nights. Remember, you also have to maintain your ducts so your room temperatures don’t go to unbearable extremes.

If you’re moving into a home that needs renovations, it could also be that the ductwork size does not fit the new room size.

are another cause of antarctic-filled nights, usually primarily felt in the bedroom. If you’re wondering why your bedroom is so cold, first make sure your vents are at peak performance. Every room should be the same temperature when, for instance, your fireplace is lit.

A poorly functioning vent might not be the problem, though. You may have blocked your vents with furniture, or it may need to be cleaned. Luckily, these are both easy fixes that can make a world of difference.

How to Test Thermostat and Insulation

are another common yet easily missed cause of cold rooms in a house. You might be thinking you’re upping your heat or furnace, but nothing is happening. Or, the thermostat changes the temperature up to a point before giving out.

However, insulation may be the culprit you’re looking for if your thermostat isn’t to blame. How can you tell? If your room’s walls — as well as the room itself — are colder than other rooms, you might have an insulation issue

If your insulation is adequate, more often than not, window cracks are the culprits behind the ice-cold temperatures in a home. But if you’re not certain what the root cause is, there are a few quick tests you can do to be sure of a window leak. Once you determine the location of the issue, your thermostat or insulation issues can be fixed by following a few simple steps.

How to Test for a Window Leak

The first option is simply to look for visible cracks in your windows — both from the outside and inside of your home. Another way to detect drafts is by placing your hand near a window and feeling for air.

You can also perform the lighter, candle, or match test — and a hairdryer might need to be involved. Hold the flame up to the window to see if it is still or gets blown to the side. If the flame pulls towards a particular direction, there’s your leak. If you don’t notice a pull or are unsure, take a hairdryer and give it to someone to use outside the window while you do the test. If there’s a flicker, there’s a leak.

The last test can be done with the help of a thermal camera, which you can buy or rent from your local hardware store. This option is more costly but works a lot faster by exposing the source of energy leaks and poor insulation areas.

After identifying the source of the issue, you can get started on finding a suitable solution to get your home back on track.

If you’ve done one or more of the above tests and find your windows have an opening, or if you identified one of the other reasons listed above as your culprit, there’s a fix. Let’s look at a few.

How to Fix a Cold Room

Fix Your Ductwork

If you’re wondering why your room is so cold compared to the rest of your house, your ductwork may need a fix. Follow these steps to fix a cold room with ductwork issues:

  1. Turn off the HVAC and check the ductwork and heating vents for debris.
  2. Look for cracks in your ductwork. You may be able to fix these with an aerosol polymer spray or some other gap sealant.
  3. Look for any other physical damages and address them.
  4. In addition, scout out if there’s a need to rearrange your furniture so your vents aren’t blocked.
  5. And while you’re out fixing things that affect the temperature of your room, it might be a good idea to check your air quality as well.

Fix Your Thermostat

Check the thermostat and the results it shows. Is the display working? Is your AC or furnace responding to the inputs from your thermostat? Are there differences in temperature between rooms? If you’re having thermostat issues, try doing the following:

  1. Clean your thermostat.
  2. Replace the batteries.
  3. Check your HVAC power circuits
  4. Troubleshoot older thermostats by opening them and pushing the metal strip in either direction.

If all of these fail, it might be time to replace your thermostat once you’re sure it is the source of your temperature disparities.

Fix Your Insulation

If your walls, ceiling, and roof are also cold, the insulation might be compromised and require fixing. Additionally, you might want to check the fireplace if you have one, as well as your chimney, for any possible damages to the insulation around them.

Insulation issues can also prove a hassle during these pandemic times when most of us do more virtual calling. Poor insulation means more noise on our calls, and less peace and quiet to work in.

Wall and ceiling insulation issues often require professional assistance to ensure safety and proper maintenance. However, if you’re dealing with window insulation issues, there are a few ways to fix this problem without having to hire professionals. With this being said, not all DIY solutions are the best.

Bubble wrap or saran wrap both act as quick fixes for insulation problems, but they come with a few drawbacks:

  1. You would have to redo them every year.
  2. You’re likely to have window damage due to the do-it-yourself nature
  3. You risk having to repair or repaint the area, costing more money and time

Fix Your Windows and Doors

Are there any holes in the frame or the casement of your windows? If you did one of the tests above and found your windows have an air leak, caulking might be the solution for your cold air woes.

To utilize this temporary fix, follow these steps:

  1. Clean the area you want to caulk with soap and water.
  2. Once dry, steadily apply the caulk at a 45-degree angle to really get into those cracks.
  3. Use a putty knife to push the caulk into cracks if it leaks out.
  4. Once dry, and only if you’re not sure you put enough on there, apply another layer of caulk for security.

Keep in mind, caulking works best if the temperature is 45 degrees Fahrenheit or higher.

For air leaks that lie between the window rail and the sill, you may try weather stripping.

  1. Start with a clean, dry area.
  2. Measure the width of the window.
  3. Cut your weatherstripping to your measurements.
  4. Apply using the manufacturer’s instructions.

There are a few other ways to seal your windows ahead of the winter months . But if your windows are old, it’s best to consider additional solutions.

At Indow, we want you to have a beautiful home. One of the best ways to maintain your home’s beauty is to prepare it for the seasons. There are various things you can do to prepare for cold months, several of them detailed above. However, it’s important to do it the right way.

Temporary solutions may work under tight time constraints. However, there is an idyllic, long-term solution for insulation issues and window leaks.

Inserts for a Guaranteed Cozy and Quiet Winter

If your home is not insulated properly or has leaks, you may also be subjected to poor sleep or find yourself using only a few rooms in your house.

Your cold room issues can be a thing of the past with our high-quality, sustainable window inserts. They not only provide insulation coverage, but they can also soundproof your home and reduce your carbon footprint.

Instead of implementing a temporary fix — like bubble wrap or saran wrap — you could be enjoying maximum insulation thanks to our acrylic inserts that work better than traditional glass ones.

Why not just buy new windows? Purchasing brand new windows for your home can be extremely expensive . Not to mention, most warranties on newer windows don’t last very long. Plus, you would have to dish out even more money for professional services, which is what you would need in order to ensure a proper installation.

And what if you want to preserve your windows? Historic homes lose part of their charm when you remove the original windows and replace them with modern options; not to mention, you may not be allowed to replace your historic windows.

With our inserts, you can keep your gorgeous historic windows without suffering through the winter. Plus, you spend a lot less money and easily recoup the investment compared to what you would’ve spent on brand new windows.

    Excellent product, support, and very clear instructions. We look forward to installing these on all our windows.

    I ordered the "acoustic grade inserts" for my bedroom to reduce road noise. They work exactly as advertised. Are they soundproofing? NO. Do they reduce noise to acceptable levels? YES. Compared to other solutions on the market (replacement windows, glass inserts etc) this is much more affordable. However, if you are looking for actual soundproofing, you need to spend more money and get something else. As a bonus, the inserts are tight fitting and have reduced drafts.

    We have single pane historic windows in our house in Newport RI. I was looking for a great solution to both temperature and noise. I decided to try the acoustic indow product.

    I am thrilled with the process and the product. James from Indow was super helpful in answering questions. The laser measuring kit was easy to use and gave you confidence in your own measuring ability as it checks your work. The 4 indow products i ordered came well packaged and were easy to put in.

    Finally, the indow inserts look great and work great. We can no longer hear every conversation outside and the birds don't wake us up every morning. My wife didn't even know they were there. They blend in and can't see them unless you look.

    I highly recommend these. More cost effective than custom storm windows, they look better and you can easily install or remove them as you need.

    Fantastic product and service.

    Indow has established the complete breadth of custom service, from initial enquiry to being very responsive to "after-sales" questions. Ours was and out-of-the ordinary project involving casement windows in a solarium and the end result turned out quite perfectly. Access to information online, instructions arriving with the delivered windows, and answers by phone insured we "enthusiastic amateurs" completed the job to satisfaction.

    I am very pleased with my Indow window inserts. I have a very old house and am near a busy road. I wanted to reduce the noise. I've just installed them and find a considerable reduction in traffic noise. They definitely were worth the cost. The measuring process is quite detailed but easy to follow and my inserts fit perfectly in crooked, 265 year old openings. The company representative Hannah Hendrickson

    was very professional, knowledgeable, and courteous. I highly recommend the Indow

    company.

    I appreciate everything about the whole Indow window process.

    Scheduling and holding a consultation online was easy and seamless. I consultant with KAYA, and he provided a thorough easy-going no pressure to move forward until I was ready consultation.

    Incentives were clearly outlined if I decided to move forward and order to be able to make my inserts even more affordable if I acted in a timely manner with measuring and submitting my order as well as returning the measure kit.

    The Indow inserts arrived within the expected timeframe and installing them was very easy. One of my favorite parts was watching how to install video, because they used humor, and it really held my attention and put me at ease, allowing me to take in all the little details I needed to insert my Indows correctly.

    Within hours, I noticed a temperature shift in the room. It was cooler and more comfortable. The next day when I worked in my office with the Indows the landscaper was across the street with the leaf blower and there was considerable reduction in noise making it a low background buzz instead of a disturbance to the work I was doing. I’ve only had them installed for three weeks and I’ve been so happy with them. It was a great investment for that room in the house that I use for my office.

    A great product. Excellent fit. Greatly reduced outside noise. Easy to install. Very happy!! Match your frame color to your current frame color and they disappear. So glad I got them.

    Well it all starts with customer service. 10 out of 10. Brain McCracken did a great job. The waiting period wasn’t long considering they had to make the window inserts and measuring the window units with the laser was actually fun. Worth every penny!

    They are working great! Very happy with the purchase.

    I'm enjoying the units, however will need to wait until next year's colder weather to get a truer feel or read on how well they work - thanks

    They work very well for my 3 Bedroom windows.easy to install.

    I purchased two Indow window inserts for two west-facing bedroom windows. These windows are exposed to the hot afternoon sun, making it difficult to cool the bedroom, and there is considerable outside noise. The Indow inserts work great at reducing the outside noise and keeping my bedroom cooler. I absolutely recommend Indow window inserts.
