Should I Upgrade My Old Duct System?

  There is much more to a good heating and cooling system than just equipment.

Do you suffer from any of these common problems?

Rooms that are too hot
Rooms that are too cold
Air that is too dry in the winter
Air that is cool but clammy in the summer
Excessive dust
Allergy or asthma suffering
Unexplained musty odors
High utility and repair bills

It's possible that the cause of these problems may be the ducts in your home.  Your ducts were more than likely designed and installed by the lowest paid worker for the lowest bidding HVAC contractor the builder could find.  If they are 5-10 years old or older, it's likely that your ducts have deteriorated to the point where conditioned air is being pumped into your attic, diminishing the amount getting to each room in your home.

Duct systems Waste Energy

“Typical duct systems lose 25 to 40% of the heating or cooling energy put out by the central furnace, heat pump or air conditioner. Homes with ducts in a protected area such as a basement may lose somewhat less than this, while some other types of systems such as attic ducts in hot, humid climates often lose more. Duct repairs could be the most important energy improvement measure you can do…”

Duct Systems Affect Comfort

“Duct leaks and improper duct sizing can affect the comfort level in your  home by keeping some rooms cooler or warmer than others, making you feel uncomfortable. The source of discomfort may be leaky ducts or Improperly sized ducts. Sealing your ducts can increase the ability of air conditioners, furnaces, and heat pumps to evenly heat and cool all of the rooms in your home.”

Duct Systems Affect Health

Duct leaks can be harmful to your health because air leaks in the duct system may contain fumes from household and garden chemicals, insulation particles, mold, and dust. These items can aggravate existing asthma and allergy problems. Why take the risk? Sealing your ducts can help you breathe easier by improving your indoor air quality, reducing the risk  of pollutants entering and circulating through your home, and avoiding potential health problems, existing duct system for leakage, poor insulation or under-sizing.

Testing is The Key

In order to determine the performance of your current duct system, have Jon Wayne perform a full diagnostic check up. Measurement test will be conducted for air leakage, pressure, airflow and speed. Current insulation levels and cleanliness will be inspected.  Appropriate recommendations or either renovation or replacement solutions will be made.

Attributes Of a New High Performance Duct System

If needed, your new high performance Air distribution system will be better in every way: 

    - Tighter
    - Better insulated
    - Clean
    - Engineered to efficiently handle total higher airflow
    - Engineered and balanced to deliver air to rooms in proper proportions
    - Engineered to solve internal room to room pressure imbalances
    - Engineered to be quitter
    - Performance tested

Planning To Buy a New High Efficiency Air Conditioner?

It is essential that evaluate the duct system, and if necessary make improvements, in order to receive the anticipated energy savings.  A bad duct system will drag down the performance of the new equipment. 

Modern High efficiency systems are much more sensitive to bad ducts.

The air movement system is more powerful. If your old duct system is leaky, the higher pressures will accelerate duct leakage. If your old ducts are restricted or undersized, the new blower will strain to overcome it and greatly increase electrical consumption and noise. Many new systems are two speed, while this improves efficiency, much of the gain is lost when connected to a bad duct system, as the longer run times lead to greater duct leakage and heat gain into or loss from the ducts.
