Why is one room in my house colder than the rest?

There are many reasons why one room is colder than the rest.

Imagine you’re walking through your home, the heat set to a warm 70 degrees, and you notice a sudden chill in the air as you enter your bedroom. No windows are open and you can feel the warmth circulating from your heater, yet this room remains chillier than the rest of the house. 

There are a handful of reasons why one room in your house feels colder than the others. Take a look below to determine what the culprit in your house may be:

1. Drafts Allowing Incoming Air

Drafts from windows or exterior doors may be causing one room in your home to be cooler than the rest by allowing outside air in. In the summer, this may lead to higher humidity levels. In the winter, colder, drier air causes inconsistencies in temperature throughout the house which makes your furnace and your wallet work harder. 

Drafts are most often caused by weak sealants around doors and windows. To locate a draft in your home: 

-Check to ensure all doors and windows are properly closed and secured. Walk past each door and window to check for incoming airflow. If it’s windy, you may even hear a slight whistling noise.

-Check your fireplace flue to ensure its shut and not allowing air to enter your living space.

If you feel incoming air from any window or door, you have a draft. To remedy a draft, 

purchase a DIY sealing kit or contact a local handyman to help seal any air leaks.   

2. HVAC Maintenance Needed

Routine maintenance for your HVAC system is crucial in ensuring your HVAC systems are working properly and heating your home in the most efficient and optimal way. Furnace or boilers that are not routinely monitored might be distributing heat unevenly throughout your home. By scheduling a routine check of your HVAC system, a trusted and experienced HVAC technician can identify if cracks in your ducts, lack of venting, or another issue with your HVAC system is causing one room to stay cooler. 

3. Venting Issues

Have you checked your vents? While an easy fix, it’s important to check that all vents in your home, particularly colder rooms or spaces, remain open and allow the maximum flow of heat into your home. 

Remember: it’s important to keep vents open at all times to maximize your home’s energy efficiency and avoid overworking your HVAC system, leading to a reduced lifetime. When your HVAC system is installed, your technician evaluates the size and placement of your system to meet the unique needs of your home. When air vents are closed, your system becomes oversized. If you have a question regarding the size of your HVAC system, be sure to reach out to our team.

4. Inadequate Insulation

Adequate insulation is key to keeping your home’s heat inside.

Adequate insulation is key to keeping your home’s heat where you want it: inside. Rooms abutting areas of your home with less insulation, such as a garage or attic, may feel cooler, indicating a need to evaluate and improve your home’s insulation. According to Energy.Gov, there are easy steps to determine whether your home needs insulation installed as well as help determine what type of insulation is best for your home.

Keeping your home warm during the winter is important for comfort and safety.
