Sealing an air duck with tape.

Duct Replacement

Air ducts carry heated and cooled air from your HVAC system into your home. Keep your home comfortable and protect your home heating and cooling investment with new or newly sealed air ducts — and earn between $200 - $800 cash back.

Air ducts are the superhighway of your home’s heating and cooling system. When they’re improperly sized, or when they leak, you can lose 30-100% of your heated/cooled air before it even reaches your home! Leakage also means that dirty air can get sucked into the duct system and distributed throughout the house, potentially causing poor indoor air quality.

New ducts can make your home more energy efficient, comfortable and safe — plus they can help reduce your energy bills.
