Insulation Information?

Our house is a small Cape, with a crawlspace attic. We’re going to get a home energy audit in the next couple of weeks, and the insulation of the attic is of particular concern for us, as it really gets quite warm on our second floor. Can I get your insulation wisdom here? [more inside]

False smoke alarms in AC ducts: troubleshooting tips?

Our new commercial space is experiencing frequent false smoke alarms in one specific area of our AC ducts. The company that installed the AC system is stumped, and so is the electronic security company that installed the smoke detectors. We've just had our ducts cleaned top to bottom but the problem persists even though we're presumably dust-free. Any thoughts on what to try next? Engineers? Inspection services?

Open Skylight: Hot or Not?

My apartment is on the top floor of a single family home. My landlord has advised that we open the skylights, one in the bathroom and one in the stairwell, to help keep the house cool. We have a window AC unit going in one of the rooms (a bedroom next to the bathroom with the skylight). It seems like opening skylights would let the cooler air out, like any window. What is the right move here to keep the apartment cool? [more inside]

Where do I find a giant fan?

I live in an open, large, loft-like apartment that gets face-meltingly hot in the New England summer. Easily near 100F in the afternoon. AC is impractical for such a big space. I've tried box fans, but I haven't found one that moves enough air to make a difference and even those were as loud as airplanes. An even faster fan sounds like a bad idea, but a much bigger and slower fan might just do the trick. Something like these, but preferably something that doesn't need to be permanently installed? Where does one find an enormous fan?

Too many volts?

Should I fix the A/C in my 2004 Honda?

I have a 2004 Honda Civic Hybrid. The clutch in the A/C compressor is bad, as diagnosed by a well-respected mechanic. He doesn't want to do the repair, recommended the dealer. Dealer price for compressor replacement is US1165(ouch). Without A/C, trips of any length are pretty miserable. The noise from an open window at 70 mph is not pleasant, and I assume it affects the mileage. I can manage short trips up to an hour or so. It's been an especially humid summer in Maine so far. The Honda has 110,000 miles, and is in good condition. I question putting so much money into a car this old(Bluebook @ 6,200), though I expect to keep driving the car for the next several years.

Help me find this article about household AC power.

I once read a great article explaining why we use polarized plugs, grounding, and GFCI outlets in household AC circuits. It was written from the perspective of an electric company whose customers keep getting electrocuted by their appliances. The company introduces the safety measures one by one and the article explains how people still get shocked. It might even have been a comment on Metafilter; I'm not sure. Where can I find it?

Which is better maintaining a cool temp or cooling down a hot house

Which would take less energy - running the AC throughout the day to maintain say 75F (outside 95-100) or letting the house get to 90F+ throughout the day and then cooling it down at night back to 75F?

What do you wish you'd known when buying a portable air conditioner?

I'm buying a portable air conditioner for our second-floor apartment. All our windows have openings at the bottom that are of the 2 panel slider variety, and no window unit will fit.

Right power supply for a home piano keyboard?

My daughter has a Yamaha psr-260 that we picked up at a garage sale. It did not have a power supply and used batteries to power up. Since the batteries have died, I have found a power supply that seems to match the piano's requirements on the back of the unit: DC IN 10-12V. The power supply says Input: AC 120V 60 Hz 20W and Output: DC 12V 1000mA with a matching polarity symbol (the plus is inside the minus). [more inside]

Cold as ice and/or burning up for your love

I have a 1700 square ft. house. I have an air conditioner/heating system that is set up to operate with the whole house as one zone. I have one room that is out of proportion to the rest of the of the rooms in the house (much larger, much higher ceiling) that is always hotter in the summer and colder in the winter. So I'm thinking the solution is for that room to be separated into a second zone. How? [more inside]

paying late AC Transit parking ticket?

Got a parking ticket from AC (Alameda County, CA) transit. Intended to pay it on time but forgot about it. The ticket has never shown up in the online or phone pay systems. I could pay by mail but am concerned that the ticket price has gone up and that I won't get notices about what I owe. I tried calling the number on the back of the ticket but can't get through to a human being to find out how much I should pay them now. Does anyone know how much the tickets go up? If I pay by mail and the price is more more than the original ticket what should happen?
