HVAC Insider Smart Maintenance Saves Money

 Given our chilly winters and blistering hot summers, those living in New York  co-ops and condos are keenly aware of 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.  

 Proper Care

 The basic components of an HVAC system are an outdoor air intake, mixed-air and  outdoor air controls, an air filter, heating and cooling coils, humidification  or de-humidification equipment, supply fans, ducts, a terminal device, a return  air system, exhaust or relief fans, self-contained heating and cooling units, a  control panel, the boiler, water chiller and cooling tower.  

 Dave Wagner, district manager at Petro Heating & Air Conditioning in Brooklyn says that for New York condos and co-ops, the most  common HVAC system is called a packaged terminal air conditioner (PTAC).  

 “The general unit is a heating and cooling type of interior/exterior mounted  unit. It takes air and it passes it across, it's an electrical unit, it passes  it across a heating coil or a cooling coil and blows it into a living space at  the desired temperature that an occupant would set it at,” he explains.
