Your Diamond Bar comfort plan
Connect the equipment proposal to the comfort complaint
Ask how the assessment addresses airflow and the existing duct layout as well as equipment operation. If a room was added or its use changed, include that information. A useful estimate explains which work is intended to address the uneven temperatures and whether any additional investigation is needed.

HVAC service in Diamond Bar.
Will replacing the outdoor unit fix uneven temperatures?
Not necessarily. Room-to-room differences can require evaluation beyond the outdoor equipment. Ask what the assessment found and how the proposed scope addresses the rooms that concern you.
