A large part of AC problems in Indian buildings, such as uneven cooling, water dripping from ceilings and outdoor units that trip in May, come from skipping design. We prepare the heat load sheet, select the equipment, and draw duct sizes, refrigerant piping routes, drain slopes and electrical load before any material is ordered.
The bill of quantities lists every item with its make, so tenders can be compared like for like and the client knows exactly what is being installed.
