It’s not uncommon to have inconsistent temperatures throughout your home. Even with your air conditioning running maybe you have that one room that just doesn’t cool down and you don’t know why. It may just be a minor inconvenience but if it bothers you there are some reasons as to why this may happen and there are things you can do to fix it.
In this article, we are going to be covering eight major reasons why your room may be getting hotter than normal which are:
- Air Vents
- AC Units
- Home Renovations
One simple reason why one room may be so hot is because your air vents aren’t open. This may seem obvious but it’s possible to have multiple air vents in one room and maybe some of them or closed; also, it’s likely that something or someone may have accidentally slid the vents closed, blocking airflow to the room. Check all of the rooms and make sure your vents are open. If there’s a specific place that is particularly hot make sure there isn’t a vent around there that might’ve slid closed.
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.
Windows are a huge reason why some parts of your home are hotter than others. Older homes often have double-pane windows that are very good at retaining heat and if you have windows that face the sunrise or sunset then those rooms can heat up during those hours of the day. If you want to make an investment you can purchase Low-E glass windows which aren;t cheap, but they are efficient in filtering the infrared and ultraviolet waves of the sun and can help keep your room cooler.
If you want a cheaper option you can buy black out shades which reflects the light out of your home but if you want to be able to see out your windows then this isn’t your best option. If you want to be able to have your shades open and keep the heat out in a cost efficient way, I recommend heat controlled window film (view on Amazon). This film tints your home and helps keep the heat from penetrating your room and the great thing is it’s inexpensive and you can purchase multiple colors if you like.
The structure of your home can play into why you may have certain areas are warmer than others. Poor insulation can cause your home to get hotter in certain areas; this is a problem more associated with older homes where parts of the insulation may need to be replaced, but newer homes can also have this problem if the insulation is uneven.
Insufficient insulation allows the cool air from your air conditioning to escape and the heat to remain. You can check the seals around your windows and doors to see if anything is peeling or damaged which will tell you that they need to be replaced. If not, you’re going to want to call a professional to come out and take a look around to see what may be causing your problem.
One problem that may cause rooms that are too hot is that your air conditioning unit is too big for your home. This is more prominent after someone buys a new AC unit and it’s too big to keep the house cool. The reason why an overlarge air conditioning unit can cause rooms to be too hot is because it will cool your house too fast. Air conditioning removes humidity along with cooling your home and when an AC is too large then the house cools down too fast and the appliance shuts off before it pulls the humidity from the room. The humidity helps rooms heat up faster and since the cycle is already complete from the AC because it’s so big, you will get warm spots throughout your home.
Another very common reason why your house is retaining heat is because of a clogged and/or old air filter. Air filters are one of the most important parts of the air conditioning unit. The point of a filter is to separate out unwanted particles like dirt, smoke, and dust from the air that cycles through your home and without it you would be more susceptible to getting sick.
If an air filter gets too dirty then the airflow is going to slow down and won’t be able to cycle through, causing rooms to remain warmer than they should be and cause inconsistent temperatures throughout the house. Make sure you regularly replace your filters (every 6-12 months depending on the added allergens to your home, i.e. pets).
One more thing, if the same room is always seeming too hot you’re going to want to check the air filter and see if it’s being pulled towards the return air vent opening. This can also restrict air flow to one specific room and cause a specific area to be constantly hot. You may want to look into finding a new filter that has a low MERV rating because more air will be able to be dispersed into your house, cooling it off.
Insulation can play a huge role in why you have areas of your home not cooling down. This becomes a bigger problem when you try to run your air conditioner and you waste money letting the cold air through leaks in your home. Luckily, there are several options to quickly insulate your house better.
One helpful tool is reflective insulation which helps keep the rooms in your house cool because it reflects heat away from the house. This is something you’re going to want to hire a professional to install properly but because of it’s made from aluminium foil and laminated on plastic or paper so the rays bounce away from the rooms you want to keep cool.
You may have noticed that your stove and oven give off a lot of heat. If you cook a lot then you will know that no matter if the AC is on and the window is open, your space in the kitchen is going to rise a few degrees in temperature. Make sure none of your appliances are what’s giving off the excess heat into your room.
On top of that, keep an eye on your electronics which can do the same thing. Large televisions, lights, lamps, and computers (especially ones with strong graphics cards) produce a lot of heat. If you constantly leave these electronics on then they’re going to generate a lot of heat in your space. Try turning them off and seeing if it changes the inconsistent air problems you’re having.

If you have recently renovated your property with additional rooms you added on, then these additions may be why some areas of your home are hotter than others. The original air conditioner was installed based on the layout for the house and if you added onto your home then you changed that layout and the air flow can get disrupted.
When you do renovations make sure that you have ductwork installed to the new rooms to make sure they’re getting airflow, you may even want to install a window in the room for full circulation. Depending on how much you added to your house, you might want to double-check that your current air conditioner is the right size for the new square footage of the house
