All the ways energy can be wasted in a residential HVAC system

Balancing out energy resources and consumption against energy waste is one of the fundamental problems of the human condition.

Extremely wealthy companies spend upwards into hundreds of millions of dollars into maximizing output to make the most money, no matter what venture it is.

On a small scale, this is a regular challenge as a homeowner in general. Electricity usage is one of the most consistent issues one has to deal with, no matter where they live or what their income is. Making sure extra lights aren’t on in unoccupied rooms, or just wasting electricity needlessly. But often the energy waste is with the heating and cooling system in particular. Leaving outside doors open for too long and letting out air conditioning is a common issue, as well as having old and leaky windows that don’t properly insulate the indoor environment from the outdoor. Even having an outside air handler will affect the energy efficiency of the entire heating and cooling system. There’s also worrying about excess furnace use in winter weather, especially if one has an electric furnace only with no access to gas heating or any sort of hydronic setup with a boiler. But worst of all—and this affects almost all central HVAC systems—is the energy leakage from ductwork. Cool or warm air will leak out of the air ducts or outdoor air will find a way inside. Even the most expensive and perfectly calibrated forced air HVAC system will lose up to 30% of its energy from pushing air through a ventilation system. This in particular is why so many people are switching to ductless heating and cooling setups, forgoing the needless energy waste of pushing the air through questionable ductwork.
