In the context of heating and cooling systems, laminar flow describes the smooth, unhindered passage of air through duct work. The opposite of laminar flow is turbulent flow, where the air tumbles around, getting caught in pockets, churning chaotically in vortices and doing a poor job of circulating. When air flows through the system smoothly, energy is conserved, whereas when the air flows turbulently, friction increases, momentum is lost and energy is wasted.
In the simplest terms, the higher the SEER value of a heating and cooling system, the more efficient and more cost-effective the system is. Many older systems still in use have SEERs of 6 or below, whereas by 1994, the average SEER for all units shipped by manufacturers in the U.S. improved to 10.61 for central air conditioners and 10.94 for central heat pumps.
Many modern heating and cooling systems are total climate control systems. An air conditioner and a heat pump are two sides of the same coin; we are often referring to complimentary functions of the same mechanism. When it comes to wintertime, the function that matters is the heat pump, extracting heat from outside air and circulating it inside the house. There is no difference in the quality and quantity of cooling and heating from a heat pump and that from other cooling and heating systems. In fact, a heat pump can expend 30 to 60 percent less energy to supply the same heat as compared to an electric furnace with a resistance heating element.
When your heating and cooling system’s fan is set to ‘on’ it operates continuously. The compressor continues to periodically cycle on and off automatically to cool and dehumidify your home when the fan is set to ‘on’ or ‘auto’ on your thermostat. The difference between the two settings is that with the fan ‘on’ and continuously circulating the air, the temperature stays more even throughout the house by clearing out pockets or layers of static, warm air.
Because newer climate control systems are generally more energy efficient than older ones, you might actually save money by replacing your old central air conditioning, heat pump and ventilation system before it completely wears out.

Consider the ever-present thermostat – a staple of American households for decades. It usually takes the shape of an unassuming box on the wall, but that modest device controls the comfort of your family on the coldest day in January and the hottest day in July.
A thermostat is a temperature-sensitive switch that controls a space conditioning unit or system, such as a furnace, air conditioner, or both. When the indoor temperature drops below or rises above the thermostat setting, the switch moves to the “on” position, and your furnace or air conditioner runs to warm or cool the house air to the setting you selected for your family’s comfort. A thermostat, in its simplest form, must be manually adjusted to change the indoor air temperature.
People spend up to 93% of their time indoors where – surprisingly – air pollution can be up to 10 times greater than outdoor levels.
This poor indoor air quality results from reduced natural ventilation – a phenomenon that has developed in recent years from tighter, more energy efficient building construction. Indoor air consists of mostly invisible gases and particulates, including many which can be characterized as pollutants. These pollutants include many substances taken for granted, such as cooking smoke and grease, aerosol sprays, tobacco smoke, animal dander, ashes, human skin flakes, household cleansers, carbon dioxide, viruses, bacteria, pollen, and fungi.
Fortunately, there is a way to have cleaner, fresher air, and that’s by using air filters in your air conditioning and/or heating system.
