What is Your Plan for the HVAC "Swing Season"?

     During this time of year in the Northeast when transitioning from Summer to Winter, we experience a difficult season for meeting HVAC demands.  Temperature and humidity is fluctuating, and this fluctuation can result in the potential need for both heating and cooling to switch back and forth, sometimes even during the same day.  But the "Swing Season" also offers a unique opportunity; it is also "FREE" Cooling season, when economizers can be utilized to take advantage of already cool outside air.

     So what should my plan be for this "Swing Season"?  At what point should I switch my HVAC system to heat and what happens if I need cooling after my heating equipment has been started up?  Are my economizers operational and ready to take advantage of cool outside air?  Below are some key points to consider as we enter the HVAC "Swing Season." 

Economizers Provide "FREE" COOLING

Economizers utilize cool outside air when it is available.  This reduces the need for a compressor to run and produce mechanically cooled air, therefore reducing energy consumption.

Below is an example of potential savings resulting in using "FREE" Cooling from an economizer, available during the "Swing Season":

 

Assuming a compressor draws approximately 15 amps to run on a cooler day, at 220v, that equates to 3.3kW

With a utility cost of approximately 20 cents per kWH, that means it costs about 66 cents per hour to run the compressor.

Let's assume you have 10 Rooftop Units at your building that is occupied 40 hours per week.  (that's 66centsx40hoursx10units)  Therefore, by utilizing the "Free" Cooling from economizers, you could save approximately $264.00 per week!

 

Is Your Heating System Ready for Winter?

Special attention should be paid to any pending repairs left over from last year's heating season.  Be assured that any known issues from last year that were not fixed WILL become problems again this year.  And furthermore, ignoring known issues will often cause additional parts to fail and lead to more costly repairs being needed.  

 

Tasks to be Performed During Heat Start Up

The necessary tasks that need to be performed during a heat start up are specific to each different type of heating equipment.  Below are some examples of tasks for 2 types of equipment.  Make sure all necessary tasks are being performed on your heating equipment:

Gas Fired Furnace Boiler
Check gas valve to ensure gas flow, check pressures Inspect burner operation: lubricate & adjust if required
Clean pilot burner and main burner for scale and dust accumulation Inspect Boiler Tubes/Chimney
Check wiring for any damaged wire Check boiler water level and low water cutout
Check vent system for soundness Check & clean as required: traps, strainers, valves, etc
Visually inspect heat exchanger and safetiess Change Oil Filters
Clean all dirt and grease from combustion air openings Change Oil Nozzles
