HVAC Moves in Thermodynamic Ways

17 Nov

You don’t need to have a physics degree to understand how heat moves. It’s all around you: cooking your eggs, steaming out of your pores, forming hurricanes, etc.

Thermodynamics is an important science lesson for anything heat-related, especially in HVAC. From heating manufacturers to repairmen, learning how heat moves from one body to another helps them paint a clearer picture of HVAC issues. For starters, it lets them know why a house is consuming excessive amounts of energy despite the functionality of the installed HVAC unit.

To illustrate, heat moves from a warmer temperature to a cooler one, as per the Second Law. The principal idea of HVAC rests on the Second Law, which helps the HVAC system keep the house, or any room in the house, at an ideal temperature throughout the day. Just as heat moves out of anything hot, anything cool grows hotter due to thermodynamics.

The simple act of leaving a window or door open while the air conditioner is at full blast testifies to the nature of heat movement. All that warm outdoor air will move inside and mix with the cool indoor air, forcing the air conditioner to work more to draw heat out. In the same fashion, warm indoor air will move out of the house toward the cool outdoor air.

Telltale Signs of Furnace Damage

11 Nov

Generally speaking, a furnace that is more than 16 years old is bound to have some defects, although even a furnace that’s reasonably new can still break down if the conditions are right. Cracks and signs of corrosion throughout the furnace body (and especially in the pipes) are obvious indicators, but you also need to watch out for less subtle symptoms like distinct changes in the “aroma” of the flame.

Similarly, huge amounts of soot around the furnace isn’t exactly what experts would call “normal” even though furnaces and other heating devices regularly accumulate dirt and grime. These dark traces of carbon buildup may actually indicate damage to the furnace’s heat exchanger or a malfunction in the burners. What constitutes a “normal” accumulation of soot may vary from one furnace model to another, so it’s best to treat any soot buildup with suspicion.

Flickering flames are also possible symptoms of a faulty burner and/or heat exchanger, although such a sign could also mean that the furnace simply needs to be cleaned. However, if any member of your household suffers from nausea, headaches, or disorientation, take it as a sign that the furnace might be emitting harmful pollutants like carbon monoxide, sulfur dioxide, and nitrogen dioxide via the cracks in the heat exchanger.
