The Denver Heating blog aims to give consumers the resources to make common heating and air conditioning decisions and maintenance.
Denver HVAC technicians will post stories and how-to's for common heating problems.

For air conditioning zone controls in large buildings you need some sort of air volume controls. The air zone controls are a modern solution to cooling big spaces. Gone are the days when air conditioning services Denver companies just install a giant air handler and have to blow through the whole building. Even if the building is completely used and there are no areas where the central air can be turned off, differences in circulation, outside air infiltration and the like cause buildings to have naturally uneven temperatures.
There is not reason to cool an area that is already 10 degrees cooler than the surrounding rooms. To achieve this effect you need your Denver HVAC company to install a VAV - Variable Air Volume system. The most common type of VAV uses remote coolers in different parts of the building. Each box is supplied with chilled water and electrical energy for heat. This creates a whole series of mini central heating and cooling. Interestingly, the history has gone from separate fans, swamp coolers and heaters in every room, to central heat, to central heat with independent devices in each area.
The Direct Digital Controls have an independent pressure and temperature setting for each zone. This is especially important for industrial and medical applications that need to maintain positive pressure to keep air quality. If the zone calls for heating or cooling, the local box can handle that. The main attraction for this is significant energy savings. Some VAV units have their own fan or share fans, while some just use one air handler to blow through conditioned air. To monitor air conditioning services Denver units you will need your HVAC tech to monitor the DDC. If the room is too cold, the DDC allows exterior air in instead of conditioned air. The system can then pull air out of the room and send it somewhere else. This minimizes compressor cycling and therefore increases the life of the whole system.
