To accurately gauge the exact climate control system requirements to keep your home or office comfortable and running efficiently is a complex calculation that takes into account many variables. From total square footage, number of rooms, ductwork measurements, and insulation factors to building materials, attic space, roof type, window design and a much more!
This detailed calculation is called a “Manual J Load Calculation”. Literally an entire HVAC manual is dedicated to this concept and these calculations should be undertaken by a trained comfort specialist. Installing too large of a systems can lead to issues such as short run cycles, which can cause humidity problem and high electric bills. Installing too small of a system can lead to extended run times, difficulty in maintaining desired temperature and high electric bills.
