What Is the Air Stack Effect?

At All Hours Plumbing, Heating & Cooling, we want to equip our customers with knowledge so they can better understand their homes. Here, we’ll discuss the air stack effect.

While this is a natural process, it can impact indoor comfort and energy efficiency, particularly during the colder months in Salt Lake City, UT. Read on to learn more about the air stack effect and how you can minimize its impact on your home.

The Air Stack Effect 101

The stack effect is the movement of air into and out of buildings, chimneys, or other contained spaces. It happens because of the differences in indoor and outdoor air density. 

During winter, warm air in your home rises and escapes through openings in the attic or upper floors. This creates lower pressure at the base of your home, which pulls colder air in through lower openings. This cycle can lead to drafts, uneven heating, and increased energy bills as your heating system works harder to replace the warm air that has escaped.

How To Combat the Air Stack Effect

Understanding the stack effect is essential for Salt Lake City homeowners who want to maintain a comfortable, energy-efficient home. Here are a few ways you can reduce the stack effect in your home:

Sealing & Insulation

One of the most effective strategies against the stack effect is improving your home’s sealing and insulation. By sealing gaps and leaks in the attic, basement, and around windows and doors, you can prevent warm air from escaping and cold air from entering. You can also upgrade the insulation in your attic and walls to help maintain consistent indoor temperatures.

Mechanical Ventilation

Bringing mechanical ventilation into your home can also help manage the stack effect. Systems like heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs) exchange indoor and outdoor air without letting heat escape, giving you fresh air circulation without the energy penalty of natural infiltration.

Door Sweeps & Weatherstripping

Simple solutions like adding door sweeps and weatherstripping around doors and windows can dramatically reduce air leakage. These cost-effective measures are easy for homeowners to install and can make a noticeable difference in your home’s comfort and heating efficiency.

Routine HVAC Maintenance

Ensuring your heating, ventilation, and air conditioning (HVAC) system is regularly maintained can minimize the air stack effect. A well-maintained system runs more efficiently and can help maintain balanced indoor air pressure and temperature.
