We had a new 2.5 ton HVAC system installed in a 1,000 sq ft retail store recently. The unit appears to be undersized.
I have talked to my contractor, who insists that the unit is adequate, and blames the problem on poor airflow (the registers are at floor level). I am highly skeptical of that explanation, as the temp never drops below 82 degrees, even at floor level.
Is there any information available on-line that would let me do my own heat load calculations so that I can indecently verify what my contractor is telling me?
Thanks,
