The Largest Source of Wasted Energy In Home!

Largest Energy User
The nation?s 113-million homes with nearly 90-million heating-A/C systems (HVAC) consume about 624-billion kWh, or over 45% of all electricity in homes. Whereas, the 90-million units with oil/gas furnaces use 56% of all household energy.
Biggest Energy Waster
But percentage of energy use is not the biggest issue - rather it?s the quantity of wasted energy. These millions of units operate at about 34 percent below their efficiency standards, wasting some 212-billion kWh of electrical energy - enough to power 17.2-million homes for one year. On a per home basis, the wasted energy is at least five-times more than the combined use of all other home devices.
Reasons for Wasted Energy
The primary reason for such waste by HVAC systems is simple: it has to do with ?starved airflow.? To operate effectively, HVAC units need 400 cubic feet of air per minute (CFM) per ton. Yet, the nation?s 90-million systems function with an average of 265-270 CFM/ton - a scarcity that accounts for much of the lost billions of kWh.

Energy wasting chokepoints that reduce efficiency of 80% to 90% nation’s heating & air conditioning systems.

Chokepoints Starve System of Airflow, Energy and Efficiency
The causes for inefficiency are multiple, but primarily associated with a combination of four system chokepoints that restrict airflow, reduce heat exchange rate and cause condenser ?slugging:?
· Over 88% filters restrict airflow
· Over 85% A/C evaporative coils restrict airflow and heat exchange
· Over 80% of return air ducts restrict airflow primarily due to filter sizing.
· Over 72% of HVAC systems have improper charge, reducing heat exchange, damaging compressor

A major culprit: the energy draining, bionesting FILTER
|
· Filters are nesting grounds for bacteria & mold, resulting in allergens, toxins & germicidal debris ? causes a loss of energy in HVAC.
· Less than 12% of homeowners maintain the filter ? accelerating bionesting process & debris - restricting airflow, starving HVAC of efficiency.
· Use of high MERV rated filters increases airflow restriction (energy loss), and biological growth.
· Most undersized, energy draining return air ducts is the result of the restrictive air filters.
· Restrictive filters cause fan to rapidly pull air/dirt into the system through cracks/holes past the filter ? added debris coats fan & coil.
· High-speed system fan peals off germs, toxins, allergens from filter & spreads debris through home.
