Air duct systems can develop holes, leaks, and cracks due to wear and tear. Unfortunately, this often results in about 20 to 30 percent loss of conditioned air, making it difficult to keep your space comfortable regardless of how you adjust the thermostat.

The good news, though, you can easily prevent this loss by sealing your ducts using professional grade materials. Professional air duct sealing typically involves the use of aluminum duct tape, ductwork mastic, and adding insulation. It is cost-effective and comes with a wide range of benefits.

Benefits of Air Duct Sealing

Here are the two main perks of having your air ducts sanitized by professional HVAC specialists.

A fall in your HVAC efficiency by about 20 percent during summer or winter will increase your energy consumption and, consequently, make your utility bills to shoot up. By fixing the leaky ducts, air will be distributed evenly to reach the intended destinations, achieving the comfortable heating and cooling temperatures more effectively within your home. This could save you money on monthly energy bills.

In addition to saving money on utility bills, air duct sealing can also prevent further serious damage to your unit. Otherwise, you’ll be subject to costly repairs and replacements.


Scheduling air duct sealing can help reduce the level of the dangerous combustion gases emitted by gas-powered appliances. Cracked air ducts in forced-air heating and cooling units increase the risk of back-drafting, which can be dangerous to your family’s health.

Backdrafting basically involves hazardous combustion gases like carbon monoxide flowing back into your rooms. And excessive leakage can cause serious carbon monoxide poisoning, which is a silent killer.

Air ducts with leaks can easily compromise the quality of air in your living spaces. Such ducts can circulate dust, fumes, and contaminants throughout your home, regardless of whether you change air filters regularly.

They can be a source of respiratory problems or aggravated allergic reactions. It’s therefore advisable to ensure the air ducts are properly sealed as soon as possible to reduce the risk of pollutants finding their way into your spaces.

By reducing the energy consumption on the heating and cooling your home, you indirectly help reduce air population levels in our environment. The power plants supplying you with the energy for powering those units in your home often use fossil fuels, which have a significant pollution effect on the environment.

Air Duct Sealing Cost

The cost of air duct sealing in San Antonio can vary depending on a variety of factors, including the size of your home, the complexity of the project, and the professional you hire. On average, the cost ranges from $1,000 to $4,000.
