It is common for mechanical systems in residential construction to be oversized which increases installation costs, wastes energy, and reduces comfort and moisture control. Properly sized equipment will last longer, provide greater comfort, reduce noise, and save homeowners money. Yet both builders and code officials are uncertain how to evaluate such calculations to assure they meet the intent of the code plus the sizing methodology approved in Air Conditioning Contractors of America (ACCA).

Ierna's Heating & Cooling can perform correct heat load calculations which will save you money & save your system. For more information please contact us today.
