mjk_na,

Thank you for that model. It has all the features I'm looking for -- but it's a little bit less powerful than I want (it's 11,800 btus). A contractor came over today and told me the 15,100...

wyounger,

Thanks again -- your suggestions are very appreciated.

If I can't find any models with that feature, I may be back with more questions!

wyounger,

Thank you for your very informative response!

By any chance, do you remember what brand you saw that had the Auto fan speed?

After thinking about it, I'm now leaning towards an...

mjk_na,

If I open a door to the hallway, the sq. footage could include as much as 2 more bedrooms and a bath.

Thanks, Jacob. If the unit is oversized, can I prevent a humidity problem by...

I'm replacing an 11,000 btu through-the-wall unit.
I've narrowed my choices down to a Kenmore 75151 (15,100 btus) and a Fedders A7D18E2A (17,500 btus).

I'm cooling an open area of about 760 sq....

That waa quick! Thanks very much.

Since the efficiency of window a/c units is measured in "EER," is that equivalent to the "SEER" ratings of central A/C? Most Energy Star window units I've seen are around 10.8 EER. I'm wondering if...

Eeeks. I appreciate the warning; I'll see what I can find out.

thomefan,

Thanks again. I guess the problem is I don't know if I'll sell...it might not be for 20 years.

perel,

It was an electrician. I'm sure he'd deny it, and I have no way of proving it....

thomefan2579,

Thanks. I'll take your advice as far as the coil.
Now the only decision is...whether or not to get A/C.
I'd be getting a 13 seer central system, vs. window units that are 10.6 eer....

Thank you everyone -- your opinions are much appreciated.

Thanks, baldLoonie. I like your logic.

John Lloyd,

I don't know if it's horizontal or not. Thank you for your advice.

Thank you for responding.

I'd never heard of an empty coil case -- it sounds like a solution.

More than one installer has told me if they don't install the A/C coil now...

We need a new furnace and ducts, but I'm not sure about central A/C.

If we have a puron-compatible A/C coil installed now with the new furnace, how long could we wait to decide on central A/C...

Do any of you recommend window a/cs that come with filters treated with antimicrobial agents? They presumably
prevent mold and mildew.

Thanks in advance,

Jacquelynn

When buying a through-the-wall unit, is it better to err on the side of under or oversizing it?

I'd like to put one in my bedroom which is approx. 163 sq.ft., no attic above, thin walls and one...

Wild Leg,

Thanks again. A dealer told me that back in 1973, they didn't make window units larger than a certain size (I thought he said 12,00 btus).

Thanks for the new link. The width and...

mjk_na,

Thanks for the link. It's interesting.

Wildleg,

I looked there and didn't see any information.

Do you have any idea what the maximum btu's would be if the unit is from 1973? That...

thehackman,

Thanks; I'll ask my handyman to look for it. The unit hasn't been cleaned in at least 33 years!

mjk_na,

Thanks for responding. It's not a studio; it's a large, open area of...

helicalrotoman,

The rooms are open to each other; the air conditioner is in the living room (which we never use), and it serves a livingroom/dining room combination, adjoining den, entry hall and...

Hi,

I have a through-the-wall Coldspot AC that's been there since at least 1973.

I'd like to replace it with a new one that has the same btu's. I've taken off the front cover, but can find no...

Is it likely that R-410A will become obsolete in 20 to 30 years?

Sorry if this repeats what's already been said, but:

If I want the system to last as long as possible -- and I don't want to risk needing to replace it simply because something became obsolete --...
