Ventilation refers to “the provision of fresh air to a room or building.” Inside your home, ventilation is an important part of maintaining a healthy environment and managing your heating and cooling costs. There are many types of ventilation, ranging from natural ventilation to forced-air systems that can improve air circulation throughout your entire home. Your Columbus HVAC expert can help you maximize the benefits of your current ventilation systems and determine whether your home could use additional ventilation solutions.
The Purpose of Ventilation
Today’s homes are built to very high standards, maintaining a secure indoor environment that allows for very little accidental air exchange with the outdoors. Thus, planned ventilation is necessary to draw fresh air into your home and encourage stale or polluted air to disperse. Proper ventilation can reduce dirt and dust buildup in your HVAC appliances and your ducts, while also preventing the buildup of humidity and moisture inside your home. Regulating humidity via ventilation not only improves general comfort, it also hinders the growth of bacteria, mold, and other potential allergens. Furthermore, moving air helps your home to feel fresh, while also contributing to indoor cooling in the summer, thereby reducing the need to use your air conditioning and lowering home energy consumption.
Your Ventilation Options
Natural ventilation is simple—this type of ventilation occurs when you open doors and windows, allowing fresh air to enter your home directly. Breezes can help to move air horizontally into and out of your home, while the chimney effect causes cool air that enters your home on its lower levels to absorb heat and rise, exiting your home via the uppermost floor. Passive attic ventilation allows heated air inside your attic to escape through vents, which can help to keep your home cooler and prevent condensation in your attic during the winter. Mechanical attic ventilation takes this concept one step further, drawing air into this space and forcing the excess out.
Ceiling fans provide ventilation during both the summer and winter. When the weather is warm, fans can create an indoor breeze to help you feel cooler; during cold weather, reversing the direction of your fan will help to circulate the air heated by your furnace through the room, improving the efficiency of your home’s heating system. Exhaust fans are small fans, typically found in kitchens and bathrooms, that draw moisture, odors, and smoke particles out of these rooms as needed to keep them dry and fresh. On a larger scale, whole-home ventilation systems help to regulate air movement mechanically through your entire home. These ventilation systems must be installed by an HVAC expert to ensure they are sized properly for your home and will provide quiet, efficient function. If you’re concerned about heat loss during the winter, energy and heat recovery systems can be installed as part of your whole-home ventilation system to reduce the loss of heat from your home when air is shunted to the outdoors. Whole-home ventilation systems typically require the addition of more attic vents to accommodate increased circulation, but can help you save money on your heating and cooling costs while improving the air quality inside your home by continually drawing fresh air inside.
