Best Practices of Ductwork Design

Best Practices of Ductwork DesignIf you are designing a new home or retrofitting areas in your current home, you certainly want and expect your contractors to use best practices of building science. The same is true for your ductwork system. Though, that wasn’t always the case when it came to construction. Read on to learn what you need to know about the tubes that carry the cooled and heated airflow that keep you comfortable.

Metal, Fiberglass, or Plastic?

Ducts are traditionally fabricated from thin sheet metal. In recent years and decades, flex ducts and plastic are often used. Many older homes use cavities inside walls, floors, and the ceiling as airways. Make sure all of your air ducts are installed using actual industry-approved materials.

Location and Insulation

The fewer turns and splits your conditioned air must travel through, the more efficient your ductwork system will be. This translates into lower energy bills and greater comfort. Ducts should take the shortest route possible from the air handler to the outlet. Conditioned areas, such as raised floors and chases, are preferable. Ducts located in unconditioned spaces should be insulated.

Sealing Materials

Cloth “duct” tape, as it’s called, should never be used to seal ductwork. It will peel and fall away very quickly. Your HVAC contractor should only use industry-approved sealing materials, such as metal tape, mastic sealant, clasps, and aerosol sealant.

Sizing Ductwork

If your contractor is sizing your duct system (or heating and cooling systems) based on the square footage of your home, find a different contractor. There are dozens of variables that affect heat gain/loss on all sides of your home. Your ducts should be sized using software based on Manual D principles outlined by the Air Conditioning Contractors of America.

Balancing and Testing

Once your ducts have been installed, sealed, and insulated, they should be tested for balance and tightness. Any leaks should be resolved and airflow to each outlet and through your home should be in balance.

Ceiling Fans: A Simple Springtime Fix May Lie Overhead

Ceiling Fans: A Simple Springtime Fix May Lie OverheadSpring is afoot, and the key to saving money on energy bills and keeping your home cool this summer may be hanging overhead and depend on your ceiling fan direction.

Whether you live near the coast, in a valley or in the mountains, you’re sure to have those San Diego days when the temperature spikes and your home begins to feel a little warmer than you’d like it to. A great way to counteract Mother Nature’s heat waves is to make sure the rotation of your ceiling fan is counterclockwise.

A counterclockwise rotation will create a windchill effect, making the entire room feel cooler, even though you haven’t adjusted your thermostat at all.

According to the United States Department of Energy, a ceiling fan rotating counterclockwise will allow you to set your thermostat four-degrees higher in the warm spring and summer months without feeling any warmer in your home. Over the course of a long, warm San Diego spring and summer, those four degrees add up to significant savings on your energy bill.

Making sure your ceiling fan direction is counterclockwise in the spring, combined with proper air conditioner maintenance and even duct sealing, can help keep you cool–and help you save a lot of cash this spring and summer–regardless of whether you live near the ocean, in the valley or on a mountain.
