8 Reasons Some Rooms Are Cooler Than Others

8 Reasons Some Rooms Are Colder Than Others

 

In a perfect world, your HVAC system should keep all of the rooms in your home the same temperature. However, as we all know, this is not a perfect world. In many homes, there may be a slight variation of temperature from room to room. Usually, this difference is so small that it goes unnoticed by members of the household. But sometimes, clients call us with complaints about major temperature differences from room to room, which can pose a big problem for comfort.

What causes these temperature differences? Can they be corrected? The good news is that most causes of temperature changes are easy to detect and yes, they can be corrected. Read on to learn the most common reasons for uneven temperatures in residential homes.

 

Different Levels

It’s common knowledge that warm air rises while cold air sinks. For those who live in a multi-story home, it is not unusual to have experiences with different temperatures on different floors, but it’s definitely not an ideal situation.

How do you correct the problem? This is an instance where zoning might be helpful. Zoning allows for different portions of the home to be temperature controlled independently. Another problem could be that your HVAC system is unbalanced, and that air just isn’t making its way to the proper rooms in an efficient manner. Either way, this is an issue where the help of a professional can go a long way towards correcting the issue.

 

Windows

Who doesn’t love a room filled with windows and natural light? Well, sometimes those windows can cause problems when it comes to maintaining a consistent temperature throughout your home. Rooms with a lot of windows can often become too warm, thanks to the greenhouse effect produced by the sun’s rays going through the glass of your windows. If the windows are drafty, they can also cause unwanted temperature changes.

One of the easiest ways to correct temperature fluctuations in a room with many windows is window treatments. Keeping the curtains or blinds closed to prevent direct sunlight from entering the room will help to lower the temperature, while leaving them open will warm a room during winter months.

For drafty windows, correcting the problem areas will help to prevent indoor climate-controlled air from being lost. Another possible solution is to invest in windows that are more energy-efficient and minimize the amount of interaction between indoor and outdoor air.

 

Dirty Filters or Ducts

Dirty filters can cause all sorts of problems with your HVAC system, including temperature imbalances. When a filter is clogged with dust, dirt, and other debris, it doesn’t allow air to flow through your system efficiently. This can cause slowdowns, where the air can’t move as quickly as usual to efficiently heat or cool the entirety of your home.

Clogged ducts are much less common, but they can happen. A partial or total blockage can create essentially the same problem posed by the clogged filter – the heated or cooled air just can’t make it to the portion of the house where it is needed.

In the case of air filters, a monthly check will help to minimize any potential problems. For ducts, you can get a sense for how dirty they may be based on a quick check of your vents – if the vents are coated in dust and dirt, it’s very possible that the inside of your ducts have the same issue. A professional can easily give your system a thorough cleaning, and confirm if this is in fact an issue in uneven heating and cooling of your home.

 

Vents Are Closed

Sometimes things just happen. In the course of cleaning a room, or moving things around, vents can accidentally be closed. If this happens, it is very likely that there will be some uneven temperature issues in that particular room.

Diagnosing this issue is easy enough – check to make sure the vents in all of the rooms of your house are open. If any have accidentally been closed, open them up and see if that corrects the problem. If not, you likely have another issue on your hands.

 

Insulation Issues

In older homes, and in more current homes with additions, it is not uncommon to find uneven insulation throughout the structure. This can lead to uneven heating and cooling problems that can be tricky to correct.

If you think uneven insulation may be the problem, you have two choices – fix the insulation issue, or use a secondary method to heat or cool the affected area. If you are dealing with an addition that’s large enough, a ductless mini-split system may be helpful. For smaller areas, it might mean investing in fans or portable heaters to keep the area at the right temperature.

 

Room Usage

How a room is used can play a big role in how well it maintains ambient temperature. For example, kitchens are notoriously hot thanks to the routine use of ovens, stoves, microwaves, and dishwashers on a regular basis. But think about spaces such as entertainment rooms or offices where you may be running electronic appliances such as large tvs or computers all day – this can cause a room to heat up much faster than expected. Even some light fixtures can produce a surprising amount of heat!

If room usage is potentially an issue, fans may help to circulate air a little better and possibly keep temperatures a little more even. This is also a case where a professional HVAC technician may be able to help with system balancing and adjust the airflow for problem areas.

 

Leaky or Damaged Ducts

If the ductwork of your HVAC system is damaged or has leaks, that can definitely have a negative effect on how well your home maintains its temperature. Fixing damaged ductwork is best left to professionals who have the right equipment to solve the problem. They can also identify any larger issues with the ducts that could be creating issues with keeping your home comfortable.

 

Unbalanced System

If no other problems can be found, it is possible that you just have an HVAC system that needs to be re-balanced. With a ducted system there are generally dampers along the ductwork that control airflow to different parts of the system – if you’re experiencing rooms that aren’t maintaining a proper temperature, along with uneven airflow through vents in your home, a technician can adjust the dampers to make sure everything is flowing evenly.
