How much HVAC do I need for a big multi-zone house?

When sizing an air conditioner for a multi-zone house, do you size it for the full house or for the largest zone? How much cooling do I really need? [more inside]

England, a heatwave and public air con: socially acceptable dress code

It is England, and we are on day one of (another) three day heatwave. Temperatures are peaking at 35C (95F) and there is more to come. Being English, I'm (a) not used to it and (b) don't have domestic air conditioning. There is, however, really good air conditioning in some supermarkets (especially Marks and Spencer food hall) and the cinema. But what, especially in the supermarket, is the least you can wear in a socially acceptable manner (remember: England)? Are there any kind of relevant guides or guidelines?

Need AC solution for fairly open space in rental

I'm getting desperate for AC solutions to a fairly open first floor in our rental. I'm in my last month of pregnancy and I'm not excited for the next few weeks or to spend hot days at home with a new baby in August while I'm on maternity leave. Any advice would be greatly appreciated! [more inside]

Which heat pump to get?

My heat pump (a 10 SEER packaged unit) is dead. It would cost at least $800 to fix it, assuming it's an easy fix. If not, it would either be unfixable (because no one makes the coils anymore), or cost well over $1k (if, for example, the reversing valve needs to be fixed/replaced). So I've had a few different quotes on new heat pumps, and can't decide what to do... Can anyone shed some light on the best route to take? [more inside]

Worth it to replace ducts when central air is replaced?

My central air system for the upstairs has croaked and I am replacing the chiller and air-handler. I have two quotes in hand from my chosen vendor: one for a 2-ton chiller (using the existing flex ducts, circa 1994) and the other for a 1.5-ton unit plus new, R-8 ductwork. The cost difference is pretty big; will the smaller-capacity unit save me enough in electricity costs to pay for the duct work? [more inside]

Resurgence, or, Can I Surge Protect My Entire Building?

The electricity in our neighborhood often spikes. So far it has killed several fancy toaster ovens, the electronics on the oven, and the rooftop air conditioner. It's easy enough to find a surge protector for a toaster oven (they make 1875 W surge protectors), but what about major appliances like ovens and air conditioners? Is there a way to surge protect where power comes into the building (in which case the entire condo building could benefit)? Are there heavy duty surge protectors for ovens and rooftop air conditioning units? Do they work?

How To Know if Heating/AC ducts should be replaced?

My place has forced heat. I'm getting quotes to cut in AC. Most reviews I read say the person who quoted the job said they should replace their ducts, and this seems like a typical upsell. Sure enough, at the first quote, the guy suggested replacing my ducts. How do I know if I need to do that or not? [more inside]

Looking for advice about replacing HVAC versus repairing.

Installing filters on my ducts

I have ducted, evaporative aircon in my house, with vents in the ceiling in every room. I am wondering if will help to install some sort of 'screen' or filter in the inside of the vents to prevent dust and insects being blown inside when we turn the system on? Would prefer a cheap/DIY solution (it's a rental). [more inside]

Please help me install a window air conditioner safely

I own this relatively new (only one season of use) 6000+ BTU GE window air conditioner, but have lost the plastic framework that allows it to be installed in a window.

Help me keep my cool...

We own a house. It's a kind of large, built-in-the-50s, added-on-to-in-the-80s, sprawly ranch-style house, but with 2 bedrooms, with vaulted ceilings, on the second floor. (Our kids' rooms.) In the summertime, they get hot, because of a.) vaulted ceilings - I've blown in insulation where I could, but there's still only 4 inches between them and the roof; b.) open stairway to downstairs - keeping the doors to the rooms closed helps a little, but kids don't really "get" that; and c.) crappy ductwork - the furnace is new, but the ducts are old, and it's a long, bendy run from the basement to the kids' rooms. I'm toying with some options for trying to improve the comfort level in our house - you are not my HVAC specialist (and I'm not opposed to talking to one), but am trying to see if my logic is sound. Special melting snowflake details inside. [more inside]

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]

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.

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?

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.
