Are there areas of your Lexington home that are not used regularly? Many households have guest bedrooms, dens, or other areas which are not regularly occupied, and too many homeowners mistakenly think that closing vents to these areas will help them save money on their energy bills.
While it seems like a practical idea – conserving energy used to heat or cool an empty room – closing vents can actually cause your HVAC systems to consume more energy. Additionally, doing so can be detrimental to whole home comfort and be harmful to your expensive heating and cooling systems.
Always keep vents open
Your heating, cooling, and duct systems were designed to work efficiently based on the size of the home, all rooms included whether they are currently in-use or not. Closing the vents reduces the area to be heated or cooled, but in a traditional HVAC system, this idea does not translate to your furnace or air conditioner. Instead, your system recognizes restricted airflow, and will work harder to power through the blockage and deliver the amount of conditioned air required for the entire home, consuming more energy and stressing components.
Pressure will also mount within the ducts when air cannot move properly through the system. The conditioned air has to go somewhere, so instead of into the rooms of your home through the intended registers, it’ll be forced through the ducts, creating new duct leaks and widening existing gaps. The energy spent to condition this air for your living spaces will be wasted, heating and cooling unused areas such as our basement or attic.
Restricted airflow and increased pressure caused by closing vents will make it difficult for your HVAC systems to keep occupied areas of the home comfortable. The added stress placed on the system can also damage HVAC components.
A smarter way to control heating and cooling energy use in unused areas is to have a zoning system installed, which will allow these spaces to be efficiently controlled without affecting the entire home negatively. Save money and improve comfort with a zoning system, designed and installed by the comfort experts at Climate Control. Our NATE-certified technicians are dedicated to helping you control energy use in ways that are safe and effective for your HVAC systems.
