Duct Sealing in Chicagoland

Increase Energy Efficiency with Duct Sealing Services from Black Diamond

Air duct sealing is a critical way to ensure that the indoor air your family breathes is pure. As your heating, ventilation, and air conditioning system runs day after day, it draws particles of dust, pollen, and other allergens into the ductwork. These irritants build up over time and eventually begin leaking into your home environment through a number of gaps and openings in your system’s air ducts.

Never ask “Where can I find a certified duct sealing company near me?” again! To schedule duct sealing services in your Illinois home or office, call the ductwork experts at Black Diamond.

Our Duct Sealing Process

When you hire Black Diamond as your McHenry duct sealing company, you’ll receive a thorough ductwork service. Our process includes:

  • Ductwork inspection: Before jumping in and sealing air gaps, your ductwork contractor inspects the entire duct system.
  • Air balance evaluation: Many duct systems have undersized return ducts, which makes the supply and return airflow unbalanced. The contractor may suggest replacing some ducts if that’s the case.
  • Damaged ductwork replacement: The contractor repairs or replaces any crushed, damaged or disconnected ducts found during the inspection.
  • Ductwork sealing: Using duct mastic, metal tape or another approved sealant, the contractor seals joints between the ductwork. Note that duct tape is not an approved sealant.
  • Register and grill sealing: Ducts aren’t the only parts that need to be sealed. The contractor also seals gaps behind registers where air enters the room and grills where air is pulled into the ductwork.
  • Addition of insulation: Ductwork that travels though unconditioned spaces should be insulated to an R-value of 6 or higher. This prevents heat loss and gain as air travels from the HVAC equipment to supply registers.
  • Filter replacement: Changing the air filter is an important part of any duct system improvement.
  • Safety tests: The contractor checks that all fuel-burning appliances are venting outside and that no backdrafting is occurring. This is when combustion fumes are drawn back into the home, which is very dangerous. A combustion safety test ensures your gas furnace is functioning safely and properly.
  • System diagnostic: Once the repairs and replacements are done, the contractor evaluates airflow one final time before the work is deemed complete. The contractor makes any last minute adjustments to ensure proper supply and return air balance.
