Are there hot or cold spots in your home? Does your air conditioner take longer to cool your home than it used to?
If the answer to either of these questions is “Yes,” it could be a direct result of duct problems, and your ductwork may need to be replaced or repaired. Replacing and/or repairing damaged ductwork can significantly lower heating and cooling cost, as well as promote more comfortable and consistent temperatures throughout your home.
What is Ductwork?
Ductwork is like a straw; it carries air from one point to another (i.e., from the air conditioner blower to the inside of your home). Ductwork is typically made of pre-insulated fiberglass hard duct board or flexible plastic, but can also be made of sheet metal ductwork (a pipe made out of sheet metal) that is insulated after it is installed.
Common ductwork problems
- Aging ductwork can begin to fall apart. Depending on the type of ductwork in your home, over time (generally 10 or more years) the outer liner begins to disintegrate and the insulation falls off. If this happens in a 100+ degree attic, the air temperature can be 10-15 degrees hotter by the time it enters the home, resulting in an increased home cooling cost of 40-60%. To address this issue, all damaged ductwork must be replaced.
- Air duct leaks, which occur when old duct sealant starts to break down or if the original installing contractor did not properly sealed the ductwork.
- Rodents, such as rats and squirrels, will also damage ductwork in search of a cool nest in the Texas heat. You may want to check your attic if you’ve had a past rodent problem.
Precision Heating & Air will complete a thorough inspection of the ductwork in your home, to determine the extent of repairs needed. Ductwork inspection is 90% visual but, in some cases, an infrared camera is used to fully inspect hard-to-see areas of ductwork.
Precision will also complete an air balance check. The majority of customer calls we receive are a result of certain areas of the home being either too cool or warm, which indicates a need to adequately balance the airflow throughout your home. This is accomplished by installing dampers, making adjustments, and using state-of-the-art equipment (such as a bolometer or air flow meter) to measure airflow velocity in the affected area.
