Our home A/C unit is dying. What next? The other day we came home and our house was 86 inside even though we had the therm set for 75. We called our normal a/c guy and and he came out and said that the main unit which normally holds 6 pounds of freon, only had 2 in it. He suspects a leak in the main coil. [more inside]

High-efficiency gas furnace installed where previously there was mid-efficiency. So it vents straight out the wall while the old furnace used the chimney. The vent is right next to the sandbox. How bad is this? [more inside]

(Oil Heat) - Getting a new oil burner / furnace. (1) How much should it cost, including installation, for a new oil furnace that's at least pretty good/efficient? (We've gotten one estimate, so far, for $10,000 (!) $11,000 for antifreeze pipe system.) What's the cost for the equipment vs cost of labor? (2) The $10K was for a System 2000. Is the System 2000 really that good? Anyone have one? How much did it cost? How much did it reduce your heating bills? [more inside]

Last spring my husband and I noticed that a small puddle of water would form on the garage floor every time we used our central a/c for more than a few minutes. We had a local a/c guy come out and he told us the pan was leaking and needed to be replaced. He quoted us around $2,000 which I thought was extremely high considering he'd done the exact same job a year previously for our neighbor (who has the same model house and, incidentally, recommended this company) for $400.

I just moved into a house that I bought, and the heater makes this 700 square-foot house nice and toasty, but the timing seems off. First something comes on, it makes a humming, sounds like a motor, but no air is coming out yet....that goes on for a minute or two, then the igniter clicks on and glows for about a minute, then flames come on for 3-5 minutes, then the fan comes on and blows heat up throughout the house.

I've just been quoted $3000 to install a new outdoor heat pump unit and remove the old one. New thermostat included. Does that sound like a lot of money?

Well, our new old apt (it's new to us, but it's old) has no range hood. Looks like the previous owner decided to make a HUGE pass through. What solutions/options do I have (besides some sort of bizaare way to hookup an ordinary rangehood). Do the somewhat reviled ionic breeze / ionic cleaners work well enough to clean the air? It's a 600 sq ft apt.
