Air Handlers
From Wiki
If you have recently purchased a unit at Windsor Place, one of the first things you may notice is that our heating and cooling system is different than what you are used to. Windsor Place is on a centralized "boiler/chiller" system. In other words, individual units do not have individual air conditioning and heating systems. Each unit has what is known as an "air handler," a relatively simple unit that has coils like conventional air conditioning systems and a blower, but the actual cooling is done at the site's central mechanical plant.
Where conventional systems rely on compressed gases like freon to chill and heat the coils in your air handler, the system at Windsor Place chills water, which is then pumped out to all the buildings and eventually runs through your air handler's coils. Many older units have air handlers that have been compromised with sediment, so that water can no longer flow through them. Because of this, your air conditioning and heating may not be optimal.
If you are experiencing this problem, you may need to replace your air handler. Air handlers in good shape can easily maintain your unit in the 70s even on the hottest days. Air handlers are considered the property of the unit owner and must be replaced by the unit owner. Although this is considerably less expensive than replacing a conventional air conditioning and heating system, some owners have had difficulty finding contractors that are qualified to do this work. Because of this, we have a list of vendors who have done work on the air handlers at Windsor Place. This is not an endorsement, but is simply intended to be a helpful starting point.
