Professional Duct Sealing Services

Duct sealing is a thorough process that addresses cracks at the seams and small holes that often allow up to 30% of conditioned air to escape. Signs of leaky ducts are rising energy bills, longer heating/cooling system run times, varying room-to-room temperatures, diminished comfort, cold or hot spots, unpleasant odors, and air quality contamination. The duct system plays an important role in the HVAC system and requires regular inspection and attention.
