    Residential Replacement

    Oversized System Correction — Phoenix, AZ

    2,800 sq ft•Manual J + Manual S

    Challenge

    A homeowner's 5-ton system was short cycling constantly. The original installer used rule-of-thumb sizing without a load calculation. Humidity was uncontrolled and energy bills were excessive.

    Solution

    Manual J analysis revealed the true load at 3 tons. We specified a properly sized variable-speed system and recommended targeted duct modifications to optimize airflow.

    Outcome

    30% reduction in energy costs. Humidity complaints eliminated. Room-to-room temperature variance reduced from 8°F to under 2°F.

    3,400 sq ft•Manual J + D + S

    Challenge

    A builder's spec home had severe comfort complaints. Second-floor bedrooms were consistently 6–8°F warmer than the main level. The existing duct layout used undersized trunk lines.

    Solution

    Complete Manual D redesign with properly sized trunk lines, balanced run-outs, and corrected fitting selections. Added return air paths for second-floor bedrooms.

    Outcome

    Temperature variance reduced to under 2°F. System airflow increased by 15%. Passed re-inspection without issues.

    Code Compliance

    REScheck Compliance — Minneapolis, MN

    3,100 sq ft•REScheck

    Challenge

    Outcome

    Permit-Ready Documentation provided promptly. Builder avoided costly delays and incorporated the insulation upgrades during framing stage.
