Duct Installation and Redesign in Franklin, IN
New ductwork requires more than basic installation. Our comprehensive duct installation and redesign service in Franklin, IN, begins with an assessment of your home’s layout, square footage, and specific needs. Following industry-standard Manual J and Manual D protocols, we calculate proper duct sizes to match your system’s capacity. This way, we can ensure that every space in your home gets adequate airflow without straining your equipment.

Do I need new ducts when replacing my HVAC system?
If your existing ducts are over 15 years old, damaged, or sized incorrectly for your new equipment, professional duct replacement makes sense.
Older ductwork often has leaks, crushed sections, or inadequate insulation that undermines even efficient modern HVAC systems. Installing a high-efficiency system on compromised ducts won’t deliver the performance you expect. A thorough inspection can reveal whether existing ductwork needs to be replaced.
What materials are best for new ductwork?
Sheet metal ducts offer durability, lasting 20 to 30 years with proper maintenance. Flexible ducts are well-suited for shorter runs and tight spaces, but they require careful installation to avoid kinks.
For homes in Greenwood, Indianapolis, and across Johnson County, we recommend materials based on your situation and budget. Our technicians explain your options and help you make informed decisions.
Expert Duct Sealing Services Near You
Our duct sealing service near you addresses these leaks using professional-grade materials. We inspect your entire duct system, identify problem areas, and seal joints and connections to create an airtight system. Using mastic sealant and metal-backed tape designed for HVAC applications, we deliver lasting results for homeowners seeking HVAC duct sealing near them.
Well-designed ductwork loses effectiveness when air escapes through gaps and poorly connected joints. ENERGY STAR reports that homes with unsealed ducts can lose 20 to 30 percent of conditioned air before it reaches living spaces. This can significantly impact efficiency and utility costs.
What are the benefits of duct sealing?
Sealed ducts improve energy efficiency and reduce monthly utility bills. You’ll notice consistent temperatures from room to room as each space receives proper airflow. Sealing also helps prevent dust and pollutants from attics or crawlspaces from being drawn into your duct system and circulated through your home.
Your heating and air conditioning equipment experiences less strain, potentially extending its lifespan. Professional duct sealing often resolves rooms that are consistently too hot or too cold.
Does Dugan Air offer duct insulation services in Franklin, IN?
At Dugan Air, we recommend combining duct insulation with duct sealing as a comprehensive solution. This is particularly important in unconditioned spaces, such as attics or crawlspaces, to prevent heat loss as air moves into your living areas. When combined with proper sealing, insulation maximizes your system’s efficiency year-round for both heating and cooling.
Signs You Need New Ductwork or Professional Duct Sealing
Watch for these telltale indicators that your ducts need professional attention:
- Uneven temperatures: Some rooms feel comfortable, while others remain stuffy or chilly, indicating design flaws or significant ductwork leakage.
- Rising energy bills: Increased costs without changes in usage patterns suggest your system is working harder to compensate for ductwork inefficiencies.
- Visible damage: Crushed flexible ducts, rusted metal sections, or gaps at connections all compromise performance and require professional ductwork installation or repairs.
- Excessive dust: When your home becomes dusty quickly after cleaning, leaky ducts may be pulling particles from attics or crawl spaces and circulating them throughout your living spaces.
- System age: Ductwork over 15 to 20 years old warrants evaluation, as older systems often lose performance due to deterioration and outdated design. Homes with older systems usually benefit from modern installation.
- Noisy operation: Rattling or whistling indicates loose connections or airflow restrictions that require professional attention.
