Common Furnace Myths That Could Be Costing You Money

Debunking the “Close Your Vents to Save Money” Myth

One of the most persistent myths in home heating is that closing vents in unused rooms will help you save money on your heating bills. This common misconception actually does more harm than good to your heating system and your wallet.

Why Closing Vents is Problematic:

Creates pressure imbalances in your ductwork
Forces your furnace to work harder
Can lead to premature system failure
May cause frozen pipes in unheated rooms

Your furnace is designed to heat a specific square footage, and closing vents doesn’t change the amount of air your system needs to move. Instead, it creates excess pressure in your ductwork, which can lead to leaks and reduced efficiency.

The Better Alternative

Instead of closing vents, consider these energy-saving alternatives:

Schedule regular maintenance checks
Install a programmable thermostat
Ensure proper insulation throughout your home
Address any ductwork leaks

At Donahue’s Heating & Cooling, we’ve seen firsthand how this myth has caused unnecessary wear and tear on heating systems throughout Greensburg, Irwin, and surrounding Pennsylvania communities. Our professional technicians recommend keeping all vents open and balanced for optimal system performance and energy efficiency.

Remember, your heating system is designed to work as a complete unit. Any attempts to outsmart it by closing vents typically result in higher energy bills and potential system damage. Trust your local heating experts to help you find genuine ways to improve your home’s energy efficiency.
