Do you have hot or cold spots in your home?
This is likely due to undersized or improperly laid ductwork. Ductwork that is damaged can cause loss of warm or cold air as it travels to the vents. Older homes can have 10% - 40% of this air lost through leakage. Not sealing this properly will add up on energy costs. Additionally, leaks can pull in contaminated air from your attic that can be very harmful to your family.
Is your ducting sweating? Is your air system running constantly and not keeping up?
80% of duct systems are undersized which can cause efficiency loss and improper airflow throughout your home.
Properly installed ductwork keeps out dirt and bacteria that can contaminate the air.
