    Yes, Mark, most people/companies are the same everywhere.
    The list is many, .. including Ryland.
    That's WHY state building codes MUST REGULATE with increasing the energy efficiency rules.

    Duct and building leakage testing should be STANDARD Everywhere AND
    a requirement for Certificate of Occupancy.
    Any building code inspector not enforcing rule ought to have a personal fine of $5,000.

    It does tell me
    you use ~2 X what I use for 1,800 Square Foot residence (~ $90/month)
    with a 3 ton 10 SEER unit built the same year.

    I guess you probably have t-stat set to 72'F in the summer
    in support of
    your local utility.
    I would love to get at least to 77 in summer but the unit works almost all the time and it does not go less than 78.

    What were the results of duct pressure tests?
