Ductwork repairs, sealing & insulating

Your ductwork is a very important part of your forced air heating and cooling system.  Poorly performing ductwork can drastically reduce your system's efficiency.  It causes it to work harder to keep your home comfortable.  Ductwork is often hidden in walls, ceilings and crawl spaces which can make them quite difficult to access and repair.  It is important to take the time to inspect and assess your current ductwork.  At Card Heating & Cooling we specialize in ductwork repairs and modifications.  We can improve the efficiency of your forced air system by sealing all leaks and insulating the ducts in your attic and unconditioned spaces.  This will improve your system's overall performance along with your comfort and indoor air quality. 

Suggested ductwork improvements:

• Check, measure and identify all leaks.
• Seal leaks and seams with mastic sealant or metal tape.
• Replace or repair any damaged, disconnected, or undersized ducts.
• Straighten out or replace any crushed or twisted flexible ducts.
• Seal all registers and grills tightly to the ducts.
• Insulate all ductwork in unconditioned spaces with an R-8 duct insulation, which is NH code!
