Take a look at the many rewards of Duct Sealing from Knight Heating & Air Conditioning:

  • Lower Energy Costs – Properly sealed ducts reduce HVAC running times, requiring less energy and trimming utility bills.
  • System Reliability – Leaks force heating/cooling equipment to work harder, run longer, and leads to wear and tear and malfunctions.
  • System Longevity – Reducing the workload of HVAC equipment extends system lifespan.
  • Superior Comfort – When maximum conditioned air reaches the destination, the home is more comfortable.
  • Healthier Air Quality – Sealing ductwork leaks prevents dust, pollen, moisture, fumes, and other contaminants from entering the system and getting spread throughout the home.
  • Less Environmental Impact – Minimizing energy consumed by heating/cooling equipment reduces your carbon footprint.

Bret did a great job identifying the issue and clarifying the problem and walked me through the cost of replacement. It was early evening so very late in the day for him, yet he was friendly and positive as he finished the repair work. He also gave me some cleaning tips that will help my system perform better!!read more
