Everyone enjoys the coziness of a warm home during the few cold winter days in Dallas, Texas. To your surprise, your home may not be very warm, forcing you to turn up your thermostat and pay a high utility price to keep your home comfortable.

Let’s look at the common causes of heat loss in homes, helping you to reduce your heat loss, increase your home’s energy-efficiency, and save money on your heating bill.

Heat Loss Through Walls

About 35% of a home’s heat is lost through the walls. Walls lacking insulation are a major point of heat loss as they are in physical contact with colder outside temperatures.

To reduce losing heat through the walls, many homes install cavity wall insulation. Insulation fills the gap between the inside and outside walls. Cavity wall insulation reduces air circulation and minimizes heat loss through the walls.

Damaged Ducts

If your duct work is damaged, the heat from your furnace won’t reach your rooms. Check the ducts in your basement or attic for damage, look for small holes or streaks of dust along the walls near the ducts.


Hot air rises, so heat is quickly depleted from your home through an uninsulated attic. However, the attic is one of the easiest places to add insulation in your home. Since the attic usually covers the entire footprint of a house, it is one of the biggest areas exposed to the elements.

Air leaks often occur in your attic, making them act like windows open to the outside cold. Sealing any leaks and adding insulation is easy, yet a major way to improve your heat that is lost.

Windows and Doors

Much heat loss also occurs through a house’s doors and windows. This is often due to air leaks or cracks, which can be repaired by caulking the joints around the door frames or windows. Additionally, installing triple-glazed windows will lower the amount of heat you lose through your windows.
