Many homeowners close the vents to unused rooms in the belief that, if these areas aren't heated or cooled, they'll save money on utility bills. However, a consultation with a reputable heating contractor could prove revealing. There are several reasons closing vents to these rooms is not a good idea. Below are the most important. 

3 Good Reasons Not to Close Duct Vents to Empty Rooms

1.  Mold Growth

Room ventilation is important for several reasons. For one, an un-air conditioned room can become excessively warm and humid. This makes it an ideal environment for mold, which takes roots in warm, moist, undisturbed areas. 

Mold can leave permanent stains, destroy furniture, and cause health issues like coughing, sneezing, skin rash, and symptoms of asthma. If you are experiencing this symptoms, contact a cooling and heating contractor to inspect your system and help you improve indoor air quality.

2. Mechanical Problems

Closing vents boosts pressure inside the duct system, so it takes more mechanical effort to blow air around. This places more wear and tear on the HVAC equipment. You may experience more frequent breakdowns, leaks in the ductwork, and less efficient heating and cooling. This often leads to higher HVAC bills.

3. Carbon Monoxide Buildup

Increasing duct pressure also increases the risk of the furnace's heat exchanger cracking. This puts your family at risk of carbon monoxide (CO) poisoning. CO is an odorless, colorless toxic gas that binds to hemoglobin in the blood and limits the body's ability to uptake oxygen. It can cause nausea, vomiting, drowsiness, headaches, and dizziness, and it can ultimately prove fatal.
