This is Turtle.
Have the Government tell manufactor of gas furnaces that they can't sell any furnace that is less than 93%AFUE and you will cut out 1/2 the customers that would burn gas as a fuel and switch to electric furnaces which can't be improved any. Then you would have to put a tax on electric furnaces to raise the price of them up to the 93% furnaces to stop them from usaing electric hogs on effency and use more energy and they will not buy them either. Then they will all stop buying central air systems and go back to panel ray heaters. Then you will have the rich people having central heat and the regular Joe using panel ray heaters.
When the Government steps into a industry the drive the prices to the moon. Back in about the early 1990's when the government stepped in and said that 80% AFUE was the lowest rating that could be sold. At this time the average gas furnace
80K BTU 71% AFUE cost me about $300.00 . Then after the 80% mandate come into effect this same furnace with a 80% rating cost me over $500.00. Now take to day and tell everybody you have to buy the 93+% AFUE verses the 80% AFUE. If the furnace runs about $600.00 you will be telling the public that the $600.00 furnace is no good and you will be paing $1,000.00 for it now because the Government thinks you need to save 13% more on gas to save some money on your gas bill.Like I said before when the Government steps into a industry, The prices go to the Moon.
