Why Are Some Rooms in the House Hotter Than Others?

A balanced HVAC unit provides each room in a home with even heating, ensuring equal comfort throughout the house. But over time, the system may develop various issues that lead to temperature fluctuations. As a result, some parts of the house are hotter than others.

Here are the potential causes of uneven cooling or heating in your home:

Improperly sized appliance

The HVAC may be too small for the space it is supposed to heat or cool. If this is the case, it can’t maintain the desired temperature, resulting in temperature differences. To address this problem, reach out to a seasoned HVAC technician. They’ll inspect the unit and recommend an appropriate replacement.

Too much sunlight

If certain rooms are more exposed to the sun than other parts of the house, they’ll heat up much faster. To cool them down, install UV-blocking blinds or shades to lower the amount of light inside.

Incorrectly placed thermostat

The HVAC runs until the area nearest the thermostat reaches the desired temperature. If the thermostat is installed on a wall that heats up faster than others, this can lead to uneven temperatures. To avoid this scenario, mount the thermostat away from areas where the temperature increases quicker. The list includes rooms with air vents, direct sunlight, hallways, kitchens, doors, and windows.

Outdated insulation

Old insulation can allow air to leak out through the walls, leaving some sections warmer or cooler than others. Plus, insulation is generally out of sight, preventing homeowners from diagnosing the issues. To determine the condition of the insulation, hire a trusted HVAC professional.

Clogged filter

Clogged HVAC filters give rise to numerous problems, including uneven cooling and heating. If airflow reaching the unit is choked due to a blocked filter, some rooms will receive less air. A clogged filter can cause other problems, so clean it regularly or change it every one to three months.

Room use

The use of each room can affect the temperature. For instance, the home office might be warmer since it contains a computer, a server, and a bunch of other electronics. To adjust the airflow, consider installing dampers. They’ll help regulate the temperatures and facilitate equal air distribution.

Home renovations

Remodeled homes often encounter uneven heating and cooling. For example, adding walls and extra floors can easily hinder the system’s operation. However, smaller home improvement projects typically aren’t huge obstacles and can usually be overcome by adjusting the dampers. Otherwise, the space may need extra ducts or an additional HVAC unit.

Multiple levels

Houses with multiple levels tend to struggle to balance the airflow. The optimal solution to this is a zoned HVAC unit. It breaks the home into several areas and allows for multiple temperature sensors. As this is a demanding project, contact a licensed HVAC contractor to perform the installation.
