As the weather and seasons change so should air conditioning profiles. From summer to winter, hot to cold, sunny to overcast, and humid to dry, it’s important for efficiency and comfort for an AC unit to adapt. Many factors affect the necessary output of a heating and cooling system and can be utilized to save energy and reduce costs.
As users consider the best profile for the time of year, an understanding of how and when the outside temperature is hot and cold is key. In a building with proper insulation, cooling can be done early in the day during summer months to help maintain a comfortable temperature during the heat’s peak without straining the AC system greatly. Similarly, heating should be done while the sun is still up and maintained as the temperature descends into the night. Changing the air conditioning systems according to the outside weather can save energy consumption when used right. In fact, approximately every 3 degrees Farhenheit change equals to 5% of energy consumption.
Different times of year also have different levels of humidity. An often-overlooked function of heating and cooling systems is regulating humidity and whisking water out of the air to make it more comfortable and safe. In hot and humid areas, air conditioning units need to run longer than necessary in less humid areas or during the time of year with lower humidity. Not only is comfort a concern, but mold can accumulate if humidity exceeds 50-60% and become hazardous. Short bursts of air conditioning are not enough to stifle this effect and units should almost never be turned fully off. With a properly programmed and flexible system, comfort and safety are maintained in all conditions.
