Ductwork Leakage & Modification

Your home's heating and cooling system is like your heart, pumping out life-giving blood to your organs and tissues. In the home, your heating and cooling unit is the heart, and your ductwork carrying warm and cool air is your veins delivering the blood. A clogged artery from too many restrictions can lead to a heart attack, similar to ductwork restrictions, such as a too small return line, improperly-sized supply lines, restricted ductwork, and duct leakage. These can all too easily overwork your HVAC unit, leading to early failure. Once our health problems are corrected, however, our breathing becomes easier and pain goes away, just as correcting ductwork issues recaptures the lost capacity of your heating and cooling system and dramatically lifts your home's comfort and energy efficiency.

​
Common Problems:
  1. Supply air not being able to cool a room
  2. Imbalanced ductwork
  3. High room pressures
  4. Restrictions in the lines
  5. Poor mixing of return airflow across the cooling coils
  6. Undersized returns

Flex ductwork

Flex ductwork is commonly used in Phoenix homes built in 1980 or later. This type of ductwork became popular because of its simplicity to install, but as a result, best practices in duct design and installation are rarely followed, or even simply ignored. In addition, some flex ducts will begin to split or crumble in time, and will need to be eventually replaced or spliced to remain functional.​

Sheet Metal Ductwork

While sheet metal ductwork is better for airflow and durability than flex ductwork, homes built with sheet metal ductwork are often plagued with issues such as undersized return lines and supply registers too close to the return.​
What we check:
  1. Static pressure 
  2. Room pressures
  3. Duct leakage
  4. Room requirements
  5. Heat load calculation
  6. Register placement 
  7. Ductwork layout
  8. Airflow on return side


What you get:
  1. A more comfortable home
  2. A lower utility bill
  3. Higher operating efficiencies of heating and cooling system
