Why Is My Room Temperature Uneven?

It's blazing hot outside, but why is it so much warmer in different rooms of your house? We hear this a lot from homeowners in Anne Arundel County, Maryland. Whether it's the bonus room over the garage that never feels right or the nursery that's unbearably hot in the summer, uneven temperatures can make your home uncomfortable and drive up your energy bill.

Common Homeowner Concerns

Many of our customers face issues with their HVAC systems that result in uneven cooling or heating. Some common complaints include:

  • Bonus Room Over the Garage: Often hot in the summer and cold in the winter.

  • Townhouse Basements: Sometimes, they get too much AC, making them uncomfortably cold.
  • Poor Airflow: HVAC vents that don’t seem to deliver enough cool air.
  • Hot Nursery: Preparing for a new baby only to find the nursery is too warm.

What We’ll Cover

In this blog, we'll dive into the reasons behind uneven room temperatures and offer practical solutions to help you achieve a more comfortable temperature throughout your home. We’ll discuss insulation issues, ductwork problems, and HVAC system inefficiencies and how addressing these can improve energy efficiency and reduce your energy bill.

Stay tuned as we explore these topics and help you understand how to keep your home cool in the summer and warm in the winter, ensuring every room in your house is as comfortable as it should be.

 

Understanding the Causes

Why Different Rooms Have Different Temperatures

When it comes to uneven temperature in your home, several factors could be at play. Let's break down the common culprits:

Insulation Issues:

  • Inadequate Insulation: Areas like attics and rooms over garages often have insufficient insulation. This leads to warm air infiltrating in the summer, causing significant temperature variations. Current building code requires R-49 levels of attic insulation which is 18” of insulation, that is one and a half feet of insulation! Homes built before 2000 likely have less than 4 to 12” of insulation.

  • Attic Air Leaks: Did you know that 20% of all air leaks in a home are in the attic? Homes built before 2000 typically didn't have any attic air sealing, leading to numerous leaks. These leaks are critical because they allow that sweltering 120-degree attic air to infiltrate your home, making it harder to maintain a comfortable temperature. Sealing your attic can significantly improve your home's energy efficiency and comfort. 

Ductwork Problems:

  • Leaky Ducts: Did you know that typical duct systems leak 30% of their air before it even reaches the farthest vents in your house? When your ducts have air leaks, the conditioned air from your HVAC system doesn’t effectively reach all rooms, leading to uneven temperatures. Additionally, this duct leakage can draw dusty attic air into your HVAC system, exacerbating allergies and lowering system efficiency.

  • Improperly Installed Ducts: Poorly designed or installed ductwork can result in some rooms receiving more cold air or heat than others.

HVAC System:

  • Improperly Sized Systems: An HVAC system that's too small or too large for your home can struggle to maintain a consistent temperature. If the system is too small, it will struggle to keep up on the hottest days of the year, leading to discomfort. Conversely, if the system is too large, it will turn on and off excessively throughout the day, failing to remove humidity from the house. This can create a damp and uncomfortable environment. A correctly sized system, possibly an Energy Star-rated unit, is crucial for achieving even cooling and heating throughout your home.

  • Inefficient Systems: Older, less efficient HVAC systems might not distribute air evenly, causing some rooms to be warmer or cooler than desired.

Airflow and Ventilation:

  • Blocked Vents: Furniture or other objects blocking vents can restrict airflow, leading to uneven temperature across rooms.

  • Poor Vent Design: Inadequately designed vents and registers can result in certain areas not receiving enough airflow.

Sun Exposure:

  • Windows and Sunlight: Rooms with more windows or those facing the sun directly can get much hotter during the summer, affecting the overall temperature balance in your home.

  • Lack of Window Treatments: Not using blinds or curtains to block out sunlight can cause rooms to heat up quickly.

Understanding these factors can help you identify why your home might have uneven temperatures. Addressing these problems can lead to a more comfortable and energy-efficient home, whether it’s an issue with insulation, ductwork, your HVAC system, or ventilation.

 

Let's Consider Your Issues And How To Solve Them

Tackling Common Hot Spots

Dealing with uneven temperatures in your home can be frustrating, especially during the sweltering summers here in Anne Arundel County. If you find some rooms are too hot while others are too cold, there are specific reasons and solutions for these temperature imbalances. Before you start making changes on your own, consider an energy audit to accurately diagnose and address the issues. Here are some common scenarios and solutions to help you achieve a comfortable temperature throughout your home.

Bonus Room Over the Garage

Insulation Improvements:

  • Insulate the Garage Ceiling and Walls: Adding insulation can significantly reduce heat transfer, making your bonus room more comfortable year-round. This is particularly important if the bonus room has attic storage spaces through the walls. Proper insulation helps maintain a consistent temperature by preventing heat from entering in the summer. 

  • Seal Air Leaks: Properly sealing gaps and cracks in your attic is crucial for maintaining a stable room temperature. By preventing warm air from entering in the summer, attic air sealing ensures a consistent and comfortable environment throughout your home. This is especially important because attic air leaks are a significant source of energy loss, driving up your energy bills and making it harder to keep your home comfortable. 

Duct Sealing Improvements:

  • Seal the ductwork with Aeroseal: Through the Aeroseal process, you can eliminate 90% of all duct leakage and deliver more air to all the vents throughout your home, especially those furthest from the HVAC system, like bonus rooms over garages. This process not only enhances airflow but also improves the overall efficiency of your HVAC system, ensuring that every room maintains a more consistent and comfortable temperature. By reducing duct leakage, you can also minimize the amount of dust and allergens circulating in your home, contributing to better indoor air quality.

Townhouse Second Floor

Zoning and Air Circulation:

  • Seal and Insulate Attic Space: Sealing the air leaks at the tops of all the 2nd-floor walls dramatically improves the 2nd-floor’s ability to reject hot attic air temperatures. This crucial step prevents the intense summer heat from infiltrating your living spaces, keeping your home cooler and more comfortable. Plus, upgrading the attic insulation to 18 inches creates a robust barrier against the 120-degree attic temperatures, significantly reducing heat transfer. This combination of air sealing and insulation ensures a more stable and pleasant indoor climate throughout the hottest months.

  • Duct Sealing: The Aeroseal process can significantly improve the airflow in your home by eliminating up to 90% of duct leakage. This is especially beneficial for the second floor of your townhouse, which can often suffer from uneven temperatures due to poor air distribution. Aeroseal enhances the efficiency of your HVAC system, ensuring that cool air reaches all rooms, including those furthest from the system. Additionally, by sealing the ducts, you can reduce the presence of dust and allergens, leading to better indoor air quality and a more comfortable living environment.

Townhouse Basement

Balancing Airflow:

  • Insulate Basement Band Joists: The band joist, located where the floor joists of the first floor meet the foundation wall, is a common source of air leaks in townhouses. This area often has gaps due to plumbing and electrical penetrations, as well as between different building materials. These air leaks can significantly impact the overall energy efficiency of your home, causing the HVAC system to work harder to maintain a comfortable temperature. This increased workload can lead to noticeable temperature imbalances between the basement and the upper floors. Properly sealing the band joist can help reduce these leaks, ensuring a more balanced and comfortable temperature throughout your home.

  • Duct Sealing: Most of the duct leakage from an HVAC system ends up in the basement. So instead of getting that cold air on the 2nd floor, you get too much of it in the basement. If you seal the ductwork, you get less cold air in the basement and more upstairs -> thus more even temperatures.

  • Adjust Vents and Registers: Properly adjusted vents and registers help balance airflow between floors, preventing the basement from receiving too much air conditioning.

  • Use a Dehumidifier: High humidity can affect temperature and comfort in basements. A dehumidifier manages moisture levels, improving temperature balance.

Poor Airflow from HVAC Vents

Ductwork and Vent Maintenance:

  • Inspect and Seal Ductwork with Aeroseal: Aeroseal technology seals duct leaks from the inside, enhancing airflow and ensuring efficient HVAC system performance.

  • Duct Cleaning and Replacing HVAC: Filters will help improve system airflow and extend equipment life by eliminating dust in the system and reducing air flow restrictions.

  • Ensure Vents and Registers are Unobstructed: Regular checks to keep vents and registers free from obstructions allow for optimal airflow throughout your home.

Hot Nursery

Window Treatments and Additional Cooling:

  • Use Blackout Curtains: Blackout curtains minimize heat gain from windows, keeping the nursery cooler during hot days.
