A way to bring down gas prices
Comments (22)ChristopherH, I don't think the government gets quite 38 percent of the price of gas in taxes. I think you may be thinking 38 cents per gallon. At least that's about what it is here. Many states are considering what NY is oonsidering -- rolling back or temporarily eliminating taxes. While that would definitely be a popular thing to do (and it would allow the politicians to tell the public "we're doing something about this") it could ultimately backfire and just put more money into the oil companies' profit columns. If the price of gas is lowered 30 cents a gallon due to a tax cut or elimination, then that just props up demand and causes people to keep using more, which causes oil prices to keep rising. In a few weeks we're paying the same as we were with the tax in place, except the money has just been diverted from the government to the oil companies. While I know many people may have a hard time choosing from between those two entities for where they'd like their money to go, I'd suggest that at least the tax money does go to accomplish some needed government function, whereas if it goes to the oil companies it just further adds to their already more than adequate profits. As far as durable plastics such as computers and car interiors, they're probably a good use of plastics. Bad uses of plastics would be throwaway items that can't be or aren't being recycled. You look at soft drinks; those used to be in glass bottles that were returned for a deposit. Now most are sold in plastic bottles, probably way under half of which are recycled. The problem with recycling up until now is that in the case of many products, it was questionable as to whether it was even worthwhile to recycle them due to the energy required to recycle being greater than the energy to make new ones. But high oil prices will change that, and hopefully we can start recycling nearly everything made of plastic. I would favor putting a deposit on plastic soft drink bottles and other recyclable items that are frequently simply thrown out to encoourage recycling of these items. These are the kinds of simple things we can do that really don't hurt anybody, cost little, but could make a big difference....See MoreA/C break down
Comments (5)We just installed a 2 ton 16 seer, (basic system. fan speed adjustable, but not variable) split system in our 860 sf house. The house has insulation above the ceilings, but not in walls. The windows are old awning windows, that don't seal great. Only 1 small s facing window. We are very comfortable at 77 degrees, and 50 - 55% humidity. Before putting it in, we had a 16,000 btu thru wall unit, along with fans. With the LR (where wall unit was) at 76 degrees, the bedroom was 80 degrees. With a fan, it was bearable. Last year, in Aug, the elec bill was $159. This year at a very comfortable temp in the whole house, the bill was $108. !!! The lack of noise was a big improvement. Our install was with all new ducts. Be sure your ducts are in good shape and of correct sizes. Having to close some vents to get MBR cool soaund like different duct sizes are needed. If doing over, I would insist that the installer put in ducts that are larger than desired, but with a damper on each branch. That way I could balance the system perfectly. The AC guys who gave quotes, said it wasn't needed. (more work for them) BS! I would have liked the ducts sized so I could close 1 room off and open the other dampers, and still have proper cfm flow. Good luck....See MoreWhy Does A/C Blow Hot Air If Outside Temp Is Above 93 degrees?
Comments (7)If everything else ( clean coils,good blower and such) is normal I'd wager (A) the unit is barly adiquate and (B) the heated discharge air is diluting intake and raiseing head pressure to the degree compressor shuts down. It's very possible as Austin pointed out,the unit isn't equiped with a high pressure switch and is shutting down on compressor overheat. In my experience shutting down on overheating compressor will soon damage compressor. At minium the oil suffers from heat and that alone will cause premature compressor failure. There are wildcards such as leaky return air giveing unit more heat than it can handle. As tiger said, op need's to tell us if compressor is running while vents blow warm air....See MoreNeed help troubleshooting a/c- temp ok, humid too high
Comments (7)"Also have checked the drain lines - no clogs, and in fact, the drain pan has been dry." " So when I say there is not water in the pan, I was referring to the overflow pan. There is water in the pan inside the unit under the coils." Did I mention , you are overlooking, omitting or mis-stating some fact(s). ??? And there she is plain and simple. With that straightened out I'll stick by my initial knee jerk,leaking return. Useing a sensitive and accurate thermometer,record air temp at intake GRILL and then record temp immediatly before air enters blower. If you find more than 1 deg differential,investigate for return leak and/or poorly insulated return. You will get advice about load calculations and such more suited to trained pros but do the simple things that better fit your wheelhouse before getting that deep. There's a recent trend of pulling all the stops regardless what the complaint is. Here's something to consider. It is plenty hot and humid in Houston Tx where many systems are intentionly oversized. It's hard to find people complaining because their ac is too large. Until you reach about 30% oversized,the biggest difference is increased operating cost. If your place call's for 3.5 tons cooling you will not complain about being uncomfortable with a 4.5. If it were so simple anyone could tell you the problem, techs wouldn't have to come out in person to figure these things out....See Moreemarston
