An inefficient or malfunctioning HVAC system is cause for concern, but the problem may not be with the furnace. It could be with the air ducts. Ductwork is an important component of the total heating system and as such, requires some attention. Leaks in the ductwork can result in the equipment working harder to maintain the same comfort level. This results in higher energy costs and also increases the chance of breakdowns requiring repair or replacement of not only the ductwork, but the system itself.
A typical home heating system uses air ducts to bring in fresh air and then transport the heated air throughout the home. Air is drawn into the system through return ducts and is pumped into the various rooms in the home through supply ducts.
1. Air duct leaks
Leaks can come from holes or cracks in the ducts, or from improper installation that leaves gaps. EnergyStar reports that up to 20% of air moving through the ductwork is lost to leaks and never makes it into the living spaces of the home. This not only means heated or cooled air is wasted, but negative air pressure can suck dirt and dust into the ducts and carry it throughout the home, compromising indoor air quality.
2. Hot and cold spots
Inconsistent room temperatures or problem areas of the home that are difficult to heat or cool can result from leaks in the air ducts, improperly sized ductwork, or ducts that are kinked or sagging. Undersized ductwork restricts airflow making it difficult to maintain the proper temperature.
3. Low air quality.
Poorly sealed air ducts can pull in outside air, or harmful fumes from chemicals stored in your home such as paint thinner, pesticides or fertilizer.
4. High energy bills.
Damaged or poorly installed ductwork requires your HVAC equipment to work harder and run longer in order to achieve the desired comfort level. This translates into higher than necessary energy costs.
5. Excessive dust.
All homes have some dust, but excessive dust could be coming in through compromised air ducts.
