    11 flex ducts tied to supply plenum, 30" long. Flex runs 30 to40 feet to far side. It's like spaghetti noodles in this attic. Classic

    Is there a question as to why? It is pretty obvious, yes? Ugly!

    Looks like a monster in the attic. Would scare me in the dark.

    & 1500 sf, 100,000 btu/4 ton?
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.
    What is comfort? Well, it AIN'T just TEMPERATURE!

    Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

    Looks like that in every attic here in Las Vegas. Some may have a bunch of "splitter boxes" as well. Never saw anything like it until I moved here. I get a lot of airflow problem service calls.

    What most of the HVAC guys around here would tell them a "variable-speed" blower would solve the airflow problems.

    Right!

    Hey its cheap! Isn't that the best? The ethnic install crew rides around in a 4door flatbed loaded down. They do it in 1 day.

    And usually they get sold a bigger unit to fix that!
