Louisville's Home Comfort and Energy Experts Since 1866

Air Flow Solutions

The comfort and energy-efficiency of your home are related to three key factors, often cited as the “three legs” of the home performance stool:

  1. 1) The HVAC equipment
  2. 2) The insulation value and air-tightness of the home’s exterior “envelope”
  3. 3) The duct system

Most HVAC contractors focus only on #1, but truly high-performing systems are rarely achieved if the home’s envelope is ignored and the duct system isn’t addressed for proper design and air-tightness.  Even the highest-rated new HVAC systems perform at greatly reduced efficiencies due to these oversights, and homeowners often notice that the comfort issues that led them to a new system haven’t been resolved once it’s installed.

A.N. Roth understands the importance of all three legs of the stool, and offers solutions for poorly performing duct systems (yours is probably one of them) that allow our HVAC units to perform at their highest levels.

Duct sealing:

Leaky ductwork is an epidemic in our homes, and sealing those leaks is one of the smartest ways of increasing an HVAC system’s overall efficiency.  It’s more than energy that’s at stake, too – leaks near the system’s exhaust or a water heater can affect pressures in those spaces enough to “back-draft” exhaust gases into the living space (!).

A.N. Roth has long been Louisville’s expert in duct sealing, combining both careful hand-sealing practices and the Aeroseal system to convert energy- and comfort-sapping ducts into tight, reliable distribution systems that will serve over the lifespan of several HVAC units.  Have your system looked at today, especially if any of your ducts are located in “unconditioned” spaces like attics or crawlspaces, which are especially wasteful.

Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. It was developed in the 1990’s at U.C. Berkeley with funding from the United states Department of Energy, Environmental Protection Agency, California Institute for Energy Efficiency, and Electric Power Research Institute. Additionally, the Department of Energy declared Aeroseal as one of the most beneficial energy technologies for American consumers.

Duct Redesign:

Many comfort issues in homes are the result of duct systems that were poorly designed:  too small, too many twists and turns, overly restrictive filters . . . the list goes on.  A.N. Roth technicians know how to spot these choke points, and to cost-effectively re-work those sections of your system that have been robbing its efficiency and ability to deliver heat or cool.
