Ventilation Gets Rid of Stale Air, but Which Type to Use?

The adequate ventilation of the air in your home makes a big difference in the quality of the air that you breathe. Ventilation is very important because it supplies you with fresh air and it can also lower the indoor humidity.

Types of whole-house ventilation systems:

  • Exhaust system – Typically consists of a single fan connected to a single exhaust point. This system works well in cold climates and it is easy to install.
  • Balanced system – Typically has two fans and two duct systems, one for supply and one for exhaust. This type of system is appropriate for all climates.
  • Supply system – This system works by forcing outside air into your home thereby pressurizing your home. The system works well in a humid climate and is relatively inexpensive to install, allows the filtering of pollutants and can help to dehumidify your home.
  • Energy recovering system – This type of systems reduce energy costs by using a heat exchanger to either warm cold air or chill warm air coming in. The energy recovering system works well in extreme climates (hot or cold) and reduces energy costs.

What to look for when choosing a whole-house system:

  • Quietness – Fans should be installed correctly to isolate noise and vibration. Look for fans with a noise rating of less than one sone.
  • Controls – Controls should have a clearly labeled on/off switch that is installed in a position that prevents accidental use. Programmable controls are also available.
  • Distribution of air – Tests should be conducted on new installations to ensure that adequate air is delivered to all rooms.
  • Filtration of outside air – The ability of a system to filter incoming air is a very important factor in the improvement of the quality of air in your home.

It is important to speak to your local HVAC contractor about the best option for your home when installing a whole-house ventilation system.
