Your air ducts are a vital system in your home. If the ducts are clogged, poorly sealed or poorly insulated, they’re likely affecting indoor air quality and contributing to higher energy bills.
Here are some duct repair and maintenance tips to help you protect indoor air quality and save on heating and cooling bills.
Check the ducts for air leaks
Begin the inspection by looking for sections that ought to be joined but have separated. Proceed to find glaring holes.
Use duct mastic to seal ductwork seams and joints
The U.S Department of Energy recommends duct mastic since the material is more durable than ordinary tape. Besides, duct mastic is usually easier to use. However, duct mastic cannot bridge gaps that are over a ¼ inch. You should first bridge such gaps with an appropriate heat-approved tape. Never use cloth-backed, rubber adhesive duct tape, as such tape tends to fail quickly.
Clean the ducts
According to the U.S. Environmental Protection Agency and Larsen HVAC, consider hiring furnace duct cleaning if:
- Mold is growing inside hard surface ducts or on other components of your HVAC system.
- Vermin has infested the ducts.
- The ducts have excessive amounts of dust and debris.
Install supply and return registers in all living areas
If you need to convert your basement into a living area, ask a professional to install supply and return registers in all the basement rooms.
Install a CO monitor
A carbon monoxide monitor can alert you to potentially hazardous CO levels. Install the monitor if your home has a fuel-burning furnace or any other fuel-burning appliance.
Get professional assistance when doing ductwork
Professional help is always necessary when there is the need to make changes and repairs to the duct system.
If your ducts are leaking heated air into unheated spaces, you are paying unnecessary energy bills. You can reduce your loss by sealing and insulating the ducts. You can also save money by making simple upgrades and making sure that existing ducts are not blocked or clogged.
