Ideally, yes. Because heat rises, multi-level buildings with single systems that condition area on multiple levels are not able to maintain even temperatures on each level. The best practice includes having separate HVAC systems for each level. If this is not possible, at a bare minimum, zone damper/control systems should be installed to allow airflow delivery control to each level independently. Keep in mind that zone and bypass dampers must be fully accessible for service and replacement after installation.

There is a common misconception that turning your thermostat completely off or raising/lowering the temperature 8-10 degrees while your office is unoccupied will result in energy savings. This is actually not the case! Especially during the summer, when the indoor temperature and humidity increase well beyond comfort levels, your system will work extremely hard to return the building to occupied comfort conditions. The best practice is to set your temperature back no more than 3-5 degrees because setting back further will result in higher utility costs.

Aside from the associated health and indoor air quality benefits, having leaky duct systems sealed can also save you quite a bit of money! The U.S. Department of Energy reports the typical office may lose from 20 to 30% of its conditioned air due to leaky ducts. As a result, your comfort system works harder and longer, consumes much more energy, and wears out sooner. The more leaky the duct system, the more savings to be had, but we have seen annual energy savings as high as 30% after performing our patented Aeroseal duct sealing process!

Chances are the additional internal heat gain from the electronic equipment was not accounted for when the comfort system was originally sized. Depending on the specific shortage of capacity/airflow, corrective actions may require replacement of ductwork, air devices, or even comfort equipment to achieve adequate comfort in these rooms.

While keeping your outdoor coil clean is imperative for proper system operation and maximum energy efficiency, spraying it with a hose can actually cause more harm than benefit. Your outdoor unit draws air from the outside of the unit in through the condenser coil, and spraying water from the outside in can actually push surface sediment and debris further into the coil. Properly cleaning condenser coils often requires the application of a specialty cleaner and rinsing the coil in the opposite direction that air flows through it.
