The heating, ventilating and air conditioning system (HVAC) in your building is designed to control individual floors independent of the rest of the building.

The interior or "core" areas of individual floors are supplied by an air-handling unit.  Perimeter offices have additional units called heat pumps. These perimeter units can be individually controlled on an office-by-office basis to provide heating or cooling throughout the year.  The heat pump system offers our Clients the most versatility in adjusting the air temperature to specific needs.

The HVAC system is automatically controlled by a computerized energy management system, which is interfaced with a central computer that is monitored and controlled by Akridge engineers.  Besides monitoring normal hours of operation, certain integral functions such as condenser water temperature, condenser water flow, night set-back thermostats and cooling tower temperatures are monitored by our company during the day and Kastle Systems during off hours.

These safeguards have been incorporated into our management practice to ensure a comfortable workplace expected by our Clients in a superior office building.

The HVAC system is serviced regularly for preventive maintenance.  To minimize distraction to our Clients, we schedule filter changing and maintenance at night and on weekends.  But from time to time an emergency situation may require maintenance or repairs during normal working hours.  We try to keep this work to a minimum and, in most instances, advise our Clients prior to commencing service.  We appreciate your cooperation in the event we are unable to notify you.

To achieve maximum efficiency from the HVAC system, remember the following guidelines:

• Do not set papers, books, files, etc., on the heat pump unit.  This blocks the discharge air and greatly restricts the unit’s ability to heat or cool.  It will eventually cause a breakdown.
• Do not push desks, bookcases, credenzas, etc., up against the unit.  This blocks the return air, which will eventually cause the unit to malfunction.
• If your unit is just blowing air without heating or cooling, the compressor may have had a momentary failure and needs to be reset.  To reset simply turn your unit off, wait approximately 1-2 minutes, and turn the unit back on.  You should be able to hear the compressor "kick in" and feel a temperature change immediately.  If you do not, please call our office and we will immediately send an engineer.
• Should you ever observe loud noises, unusual smells or unit water leaks, turn the unit off immediately and report it to our office.
• When requesting air service, please indicate whether the problem is with interior space or an individual's heat pump. This saves our personnel considerable time in trouble-shooting problems.

Normal heating, ventilating, and air conditioning (HVAC) system hours are Monday through Friday (except legal holidays) from 8:00 AM until 8:00 PM.  As our Client, you are entitled to heating or cooling Monday through Friday from 8:00 AM to 8:00 PM and on Saturdays between the hours of 8:00 AM and 3:00 PM without any additional expense.

1. To turn your air conditioning on, press one (1).  To turn it off, press zero (0) now.
2. Please press the number of the desired zone followed by pound (#).  See building zones at the end of this section.
3. Please enter your Kastle card number.  Use pound (#) where the dash appears and pound (#) at the end. For example: card number 428-1234 would be punched in as 428#1234#.
4. The system will confirm your request with the following message:
   • Turn (on/off) the air conditioning.
   • The number you have entered is 428-1234.
   • If this is correct, press pound (#).
   • If this is incorrect, press star (*) and begin again.

After you press pound (#) to confirm your request, hang up the phone.  In approximately five minutes, heating or cooling will begin or end.  The control center's computer will record your code number, the floor that was activated, and the time the system was activated.

Air Conditioning Zone Assignments

If you experience problems while attempting to set up HVAC with the TONE system, please call Kastle directly at 703.596.3698.

HVAC will run automatically for a 4 hour time period when requested through the TONE system unless you call and turn the air off. If HVAC is needed beyond a four hour window, please call again once the four hours has passed and activate the HVAC again.
