North Carolina, which is filled with Longleaf and Loblolly pine, is a yellow pollen paradise. According to Robert Bardon, a professor of forestry and environmental resources at N.C. State University, we should start seeing the onset in the next week or so, around April 1.
Two of the basic components of a refrigeration or HVAC system are the condenser coils and the evaporator coils with fan-forced air moving over them. Keeping them clean is an extremely important part of maintenance. With the condenser most commonly placed on the roof of your business, it is exposed to grease from the kitchen exhaust fans, pollen, and all sorts of physical pollution. When this debris collects on your condenser coils it reduces the effectiveness of the system and causes parts, especially the compressor, to work harder. When you consider the cost of replacing just one compressor would cover the cost of cleaning that same HVAC unit for up to five years it’s easy to see the benefits of our semi-annual HVAC planned maintenance program.
When is the peak of pollen season? (Warning: This following part is for serious weather geeks only.) The pine pollen season is based on the number of days that the temperature is above 55 degrees after Feb. 1. To calculate the peak, add the positive differences between the daily high temperature and 55 degrees. Once a total of 636 degree-days is reached, pollen production is at its peak. Pollen begins shedding before peak and may occur when the total is at about 300 degree-days. (credit to the Charlotte Observer for the quote).
