Sizing a System in Chicago

Correctly sizing a heating or air conditioning system is extremely important. If the system is too small, it will not adequately control the temperature of the house on especially cold and especially warm days. If the system is too large, it will cycle on and off frequently, creating excess noise, lower efficiency, and potentially decreased humidity control. Since operating inefficiencies occur as the system cycles on and off, additional cycles waste energy. Many contractors recommend having a load calculation performed in order to most accurately size an HVAC system. A load calculation is a complete evaluation of the home based on factors like climate, size, and configuration of the home and ventilation. A professional HVAC technician should be able to find the most efficient system for your home. Many homeowners find that new, highly efficient systems pay for themselves in a short period of time through lower power and gas bills and lower maintenance costs. Because the air conditioning and heating contractor selling the system also sizes it, it is vital to buy systems from reputable companies.
