Determining and Solving Ventilation Problems

Published on: April 25, 2012

Your air conditioner cannot solve ventilation problems in the house by itself. It will work as hard as it can to remove excess humidity from the air to prevent mold growth. If it works too hard for too long, it will break down. You may need extensive air conditioning repair to get it working again.

Ventilation problems are not always apparent to a homeowner. If the house feels stuffy, mold is present or the walls are damp when the air conditioner is working, ventilation problems may be present. Air must be allowed to flow into and out of a house. Having air conditioning repair work done will improve indoor ventilation, but the air conditioner can only do so much.

 

The attic is often overlooked for ventilation. In the summer, the heated air causes the air conditioner to work much harder than it should. The heated air also causes the roof decking and shingles to fail before their time. Adding proper ventilation to the attic will prevent premature roof and air conditioning repair.

 

There are different things a homeowner can do to add ventilation to a house. These items include:

• Attic fans
• Ridge vent
• Air turbines
• Soffit vents
• Bathroom vents in the laundry room
• Venting the roof in an attached garage
• Whole house fan
• Opening and keeping room vents clear

 

Your air conditioning repair should include cleaning and repairing the air ducts. This prevents moist air from leaking into the attic. Insulating the ducting system prevents condensation from forming and causing damage. The ventilation system in the attic can work more efficiently.

If your HVAC system is more than ten years old, you may consider upgrading to a better model. Systems are available that allow the homeowner to select the indoor humidity levels. This helps improve the house’s ventilation. Your local HVAC company can advise you of the best methods and products to properly ventilate your house.
