Burgaw homeowners: Summer is coming, and so are the rodents. 🐀
Did you know that new flexible ductwork can be destroyed by rodents the very first night it’s installed? Even worse, because they tunnel inside the insulation, it’s nearly impossible to find that damage during a standard annual inspection. You only find out when your electric bill skyrockets or your air starts smelling foul.
At Indoor Mechanical Service, we do things differently. We install rigid hard-pipe ductwork sealed with closed-cell spray foam.
🛡️ Rodent Proof: They can’t chew through it.
🛡️ Visible Security: No hidden tunnels or invisible leaks.
🛡️ Iron-Clad Warranty: Lifetime protection against rodents, mold, and water.
🛡️ Our Promise: If there is ever a workmanship issue, we fix it for FREE with a rapid response.
Don't pay for the same job twice. We offer financing options to help you upgrade to the last duct system your home will ever need.
Upgrading to rigid hard-pipe ductwork offers significant performance advantages in terms of airflow, equipment longevity, and energy efficiency.
Superior Airflow Performance
Rigid metal ductwork provides the lowest resistance to airflow of all ducting options because of its smooth interior surfaces.
Airflow Capacity:
For the same duct diameter, rigid metal ducts handle significantly higher volumes of air (measured in CFM). For example, a 10-inch metal duct can move up to 360 CFM, while a flexible duct of the same size is typically capped at 270 CFM.
The "Compression" Penalty: Even minor installation flaws in flex duct drastically reduce performance. Just 4% compression (slight slack) in a flexible duct can move 37% less air than a rigid metal duct.
Resistance and Friction: At 30% compression, friction rates in flex duct quadruple, and studies have shown pressure losses up to 10 times greater than steel duct.
System Longevity
Rigid ductwork is a "forever" solution that protects your entire HVAC system.
Ductwork Lifespan: Rigid metal ducts typically last 30 to 50 years or more with proper maintenance. In contrast, flexible ductwork usually lasts only 10 to 20 years at most due to its susceptibility to sagging, tearing, and environmental degradation.
Equipment Strain: Because rigid ducts allow air to move with minimal resistance, they reduce strain on the blower motor. High static pressure from flex ducts forces fan motors to work significantly harder, which can lead to premature HVAC equipment failure.
Lower Electric Bills
Investing in superior ductwork design can lead to substantial long-term savings on utility costs.
Energy Savings: Research shows that homes with properly designed and sealed ductwork can save 20% to 30% on energy bills.
Fan Motor Efficiency: A significant portion of the "energy penalty" for flex ducts comes from increased fan motor energy. In one test, flex ducts required 72% more daily fan motor energy than metal ducts to maintain performance.
Reduced Thermal Loss: When combined with spray foam insulation, rigid ducts eliminate air leakage and drafts, further optimizing efficiency.
This setup not only resists pests but also acts as an air and v***r barrier. Additionally, rigid duct customers receive free cleaning and sanitizing every three years, a service you otherwise value starting at $450.
