Duct sealing lasts anywhere from 10 to 15 years. If you use quality materials and have a professional handle the duct sealing, it could last closer to the end of that range. However, most flex duct systems only last about 15 years and no amount of care will make them last longer. You should ask your HVAC technician about the length of time your duct sealing will last.
Some of the factors that impact the longevity of the seal include the quality of the sealant, the complexity of the ducts, and the use of your heating and cooling system. If you schedule frequent duct cleaning and inspections, you’re less likely to have trouble with your ducts. A professional may be able to identify an issue before your ducts develop a major leak. When it comes to your HVAC ducts, a little maintenance and care goes a long way and can save you money.
On average, sealing up leaky ductwork costs anywhere from $1500 to $4000. This number varies based on the size of the leaks, the amount of leaks, and the rates of your HVAC company. If you have leaky ducts, you should schedule an inspection and repair. A reputable company will be able to give you an estimate on the cost of sealing the ductwork.
If you need a duct replacement, the cost may be higher. It’s important to ask whether or not a replacement is necessary. Your HVAC technician should be able to answer all of your questions about leaky ducts and advise you on the best solution. Sometimes, it makes more sense to replace the ducts than it does seal them. It’s worth mentioning that the energy savings you get by sealing the ducts could pay for the actual repair cost. When you have leaky ducts, you waste money on your utility bills.
If you hear strange sounds coming from your ducts, you could have leaky air ducts. Another obvious sign of air duct leakage is high energy bills. When air escapes out of the ducts, your system wastes energy producing more hot or cold air. Your leaky ducts are likely to result in a spike in your energy bill. It may also cause your system to run frequently. Sometimes, a system with leaky ducts never seems to get the home to the right temperature. As much as it tries to cool your home, it’s unable to keep up with the lost air.
If you have uneven cooling, you might be experiencing leaky ducts. You could have air escaping the ducts before it reaches a certain room of your home. If you have concerns, don’t hesitate to call a professional. They can examine your ducts and determine the best way to proceed and get your ducts sealed.
