HVAC Insider Smart Maintenance Saves Money

 With harsh winters and blistering hot summers, those living in Chicagoland’s condominium and townhome communities understand the importance of properly  working heating, ventilation, and air conditioning (HVAC) systems.  

 That’s why it’s important for managers and residents to know who is responsible for what and  how to properly maintain these systems, which could be a single heating/cooling  system for the entire building or individual furnace or cooling systems in each  unit. After all, in residences such as large high-rise buildings or townhome  communities, a variety of HVAC technologies can be found. HVAC is the umbrella  term for the system that includes all the equipment used to ventilate, heat and  cool the building, move the air through the ductwork, and have that air  filtered and clean for the occupants.  

 David Burggren, vice president of sales at Midwest Mechanical in Lombard says  that there are a variety of different HVAC systems. “It varies dramatically. Some buildings have systems that are very centralized,  other buildings have systems that are very decentralized and have much more of  the equipment in the tenant or owner's spaces. One of the common things that we  are looking at with a condo or high rise building is that there will be some  level of equipment that supports the building, the common spaces, even if the  tenants each have their own air conditioning units,” he says.  

 Burggren says that water-cooled or chiller boiler systems are also popular and  efficient for large condo buildings. They combine the chiller, boiler, pumps  and controls into a single package for simple installation and maintenance. A  water-cooled system has a cooling tower which cools water that serves all units  in a building, rather than each unit having its own.  

 “Water cooled systems are more efficient than an air-cooled chiller. They cost  more up front and there can some additional maintenance costs but they are 30  to 50 percent more efficient,” he says.
