Duct Replacement and Attic Insulation from J&W Heating and Air


It’s what you can’t see . . .
Your home’s ductwork and attic insulation can impact air quality, comfort and energy costs! Is it time for a duct replacement and attic insulation quote?

J&W Heating and Air supports your home’s whole HVAC system—but that’s not just your furnace and air conditioner. The largest part of your HVAC system is your home’s ductwork. Responsible for driving air to every room of your home, it’s often overlooked. Out of sight shouldn’t be out of mind.

If you’ve invested in a high-efficiency home comfort system, ductwork problems could prevent your equipment from delivering maximum performance. Here’s another way of thinking about it: You wouldn’t fill up a car and let gallons of fuel spill on the ground because of a hole in the gas tank. But that very problem could be happening with your ducts as an average home loses up to 30% of air that moves through its duct system due to leaks, holes and poorly connected ducts!

Properly sized, sealed and insulated ductwork can improve your comfort and energy efficiency while helping stop the spread of airborne pollutants.
