Ductwork mistakes to avoid

Are you building a new home or installing new ducts into your building? If so, be aware of some ductwork gaffes that can hurt your heating, ventilation and air conditioning and raise your energy bill.

• Selecting the correct size ductwork is essential to moving the treated air efficiently. If the ducts vibrate and make noise, they probably are the wrong size for the job. Ducts that fit better will deliver the heated and cooled air more efficiently.

• Ductwork should be sealed and insulated to maximize efficiency and protect the ducts from outside temperatures. Seals help prevent leaks, which let treated air escape, meaning that you are paying for heating and air conditioning that you are not receiving.

• Long runs of ducts can backfire unless you take steps to be sure they can sustain air flow.
