Replacing a 10- to 15-year-old Heating & Air Conditioning System with a properly sized one can save you as much as 30-40% on your Energy bill. The only accurate way to properly size a replacement Air Conditioning & Heating system is to calculate the actual heating or cooling load by completing a Manual J based load analysis.
The HVAC (Heating, Ventilation, and Air-Conditioning) systems not only consume huge amounts of a home’s total energy budget, but also impact the comfort and well-being of the occupants more than any other system in a house. Since these systems play such a large role in a home’s performance, it’s important that they receive enough “design” attention to make sure they’ll work as intended.
