Hello, I'm currently looking at replacing my mother's heating and air conditioning units because they are both frequently broken and both old and inefficient. I'm hoping that this can be used as an opportunity to save money, even though it will be a sizable upfront expense. [more inside]
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.

Different Central air conditioner and furnace brands? When it comes to HVAC, should we go with Carrier, Goodman, York, or Lennox? [more inside]
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?
Do I really need to have my furnace and AC inspected once a year? [more inside]
I have to keep calling my apartment manager in to repair the HVAC (heating and air conditioning) unit every few months. This can't be right. I know YANMRP (you are not my repair-person) but I wonder what could be going on and what I can do about it. [more inside]
Is leaving the windows in my attic cracked beneficial for keeping my air conditioning bill low? [more inside]
Do I need to have separate thermostats for my central air conditioning & my radiator heat? [more inside]
BrrrrrFilter: It's gotten cold here in Chicago and my heater appears to be broken. Google didn't help me much probably because my knowledge of HVAC is weak. Help me find out quickly if I'm being ripped off? [more inside]
What can we do to get more air from the air conditioning (and the heat in the winter) to the back of the house? [more inside]
Any idea how much a new combination electric A/C and gas heater costs? Our house is approximately 1450 square feet.
Our dog stays at home while we're out working. She does fine and has people walking her on most days, but with the generally unreliable nature of electric power on hot Virginia days, I worry that the house may lose power and heat up to an uncomfortable temperature while my wife and I are at work. Does anyone have any experience with an inexpensive, easy-to-setup way for me to get an e-mail alert if the power goes out or the temperature gets to a certain point? This looks neat, but if the house loses power it won't do me much good.
Are there any programmable or automatic thermostats that can keep a house within a certain temperature range, and not just at a certain point? For example, I don't want to set the temperature at 72°F, but have the air conditioner come on at 73°F and the heater come on at 71°F. I'd prefer a range of six degrees or so, so that the air conditioner comes on if the temperature rises above 74°F, and the heater if it falls below 68°F, or something like that. I don't pay enough attention to it now, so the temperature swings too much and it's bad for items in the house. Can't some technology do this for me?
