Why would moving a car stereo break the aircon?

My wife removed the stereo from our 2006 Renault Scenic to extract a coin that had been stuffed in the CD slot by one of our lovely children. This wasn't the first time she'd done this, and there haven't been any problems in the past. However, upon returning the unit this time, the dash controls for the stereo were found not to work, only those on the steering column. She removed the unit again, checked the fuses, replaced the unit - and now the bloody air conditioner is dead. [more inside]

Home inspector didn't test furnace & now it needs replacement. What to?

I bought a house in August this year (2.5 months ago). Just tried turning on the heat for the first time and it does not work! I had a repair company out and was told it was in terrible shape (and super old). They would even have to special order the parts. [more inside]

Water in the living room: not plumbing, not A/C condensation, not roof

Who you gonna call? -- What else can leak water? We called a plumber; no pipe leaks. Found more water in the room; it's on the other side of the wall from the A/C in the garage. We have *replaced* the A/C. We've been up in the "attic" and there's no water or water damage up there. The carpet puddle keeps getting bigger. [more inside]

Window air conditioner suddenly randomly tripping circuit breaker

We have a window A/C unit that is about three years old. Since we bought it, it has worked flawlessly to cool our bedroom for the few weeks a year that we need it... until now. We put it back in the window last Wednesday, and it worked fine until Monday evening. Now, seemingly without rhyme or reason, but usually (of course) in the middle of the night, it will trip the circuit breaker. [more inside]

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]

Air Conditioning Efficiency (Coefficient of Performance) Questions

I have come to understand that a typical modern window or residential-central air conditioner (which I believe is referred to in the industry as a "Direct Expansion" or DX unit) has a coefficient of performance which typically ranges between 3.0 and 3.5. That is to say, for every unit of energy consumed, the air conditioner removes between 3 and 3.5 units of heat from the conditioned space. I have a few questions regarding this, inside. [more inside]

What is the correct A/C refrigerant pressure for '04 Scion xB?

What is the proper air conditioning refrigerant pressure for a 2004 Scion xB? Should the pressure reading be made at a specific RPM? My A/C has been slowly loosing cooling over the last couple of years, now it really only cools well when traveling above 35~ mph, not so well at all in stop-and-go situations. Does it sound like I am on the right track to recharge the system? Works pretty well at steady-state speeds...

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?

What kind of fan can suck without overheating or dying?

I’d like to build an evaporative cooler for the coming summer, but I don’t want to start a fire. Will a box fan draw air through cooling pads (and possibly ducting) without overheating or worse, or should I look for any other type of fan? Squirrel-cage fan maybe? [more inside]

As if the bar exam wasn't horrible enough.

I'm house-sitting. A moment ago, the lights in my kitchen dimmed, and then went out. The stove was on while this happened. The A/C has also stopped blowing cold air, although it was making a weird buzzing noise before I manually shut the blower off via the thermostat. Lights and the fan in the living room are working, but everything is dead in the kitchen except the stove. Upstairs A/C and lights are dead as well. [more inside]

ComEd AC cycling: Anyone do this?

I noticed that my electricity provider, ComEd, offers an annual $40 credit if you allow them the option of cycling your central air conditioning off and on. Does anyone have any experience with this program? My house is well insulated and we keep the temperature set pretty high with a programmable thermostat, so our AC cycles on its own. I know that constant cycling is bad for the compressor, so if this has the potential to do damage, I'll skip it, but if this is an easy way to save 40 bucks, hey, why not.

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]

Air conditioning vent clearance

I have air conditioning vents in the floor at the side of the room. The vents can be angled in different directions. If I put a large dresser against the wall, above a vent, with clearance of a few inches, will it be substantially detrimental to heating/cooling?

Blowing some cool air on a hot server

Apparently as the air system in our office building has degraded, the heat in our offices during the spring and fall when the AC shuts off has become unbearable as air that is hotter than outside is blown around. Bad for people, but worse for our server room. It has gotten to the breaking point and we need to do something. I'm looking for a way to cool off our servers in the transition periods between winter and A/C being turned on. [more inside]

Got ducts?

House: The Sequel has baseboard heating. It also used to have a whole-house humidifier (removed when I installed a new boiler). Possibly because of the humidifier, the house appears to have at least three ducts w/grilles, two on the first and one on the (compact) second floor. Here's the question: could those ducts be repurposed for central A/C? (Obviously, it might be necessary to run additional ductwork off the extant ducts.) My Google-fu is failing me, perhaps because it's currently eighty-six degrees in my office.
