If I were in your position, I'd contact the ARI and equip myself with all the publications available that specifies all the specs you are seeking. This approach would be a sure bet you design it...

H-10, awesome piece of equipment!

Robert, without knowing what specific make of heat pump you have, i'd like to keep my response general of all heat pumps.

defrost initiation is usually controlled by cycles per time passage and...

sputter, undergound storage tanks in residential applications are subject to the same condensation problems as are service stations dispensing gasoline. periodically, the underground tanks must have...

I second the motion of calling Lennox! Hey Bob says it right, many service personal are not familiar with the Lennox platform, and many, many mistakes have been made because of that.

very late reading this one, but my goodness, the humour hasn't aged one iota!

excellent suggestion!

ntechnic, beenthere says it right. you would have dramatic savings by changing out to 18 SEER or higher. you might want to look into them.

about 7 or less :)

freddie, let's define what super heat is. once we thourouly understand the definition, then we can work with it.

superheat = the number of degrees by which the unsaturated vapor (containing no...

Norm, good seeing ya post!

tr23, myself, prefer to see 15 degree split or maybe a little less. the only time i've experienced 20 degree td, abnormally high head pressure readings were evident.

in the industry, that would qualify as a call back. the one who installed should be able to find the problem and fix.

ultima, you should find all your answers at this website

hkjrmd, your inspector is telling you right. the more separation you can get, the better. the hot air wouldn't be a problem, however the airborne lint particles will kill a condenser.

jir, in my honest opinion, i believe what this all means is that we are literally running out of fossil fuels to generate electricity. i live in central indiana and our power here is produced by...

danglerb, continue being who you are. if i lived in southern CA, i'd be worse than you, i've been there and i know what's going on in the industry in your area.

jir, to effectively use the SEER value for calculating cooling usage, one must know the total number of BTU's transfered for the season. without going into all the math, 15 SEER unit will use 44.6%...

danglerb, the oil is not circulating intentionally, it is a byproduct of compressor design. refrigeration machines (compressors) by design allow a small amount of oil to escape around the...

sorethumbs, i see you've been watching and reading this forum for a few days.

your length should present you no problem, however, be sure the horizontal run pitches in the direction of the...

welhan, yes, it means amps

the LRA is 'locked rotor amps', the amperage draw of the compressor at startup.

the RLA is 'rated load amps' the amperage draw of the compressor when it is working...

i believe the design process is the most tedious, most hack jobs i've seen were thrown together with no design at all. whatsoever.

uson, you'd better research superheat a little bit. pick yourself up an Alco pocket pressure-temperature chart, you will find the instructions for obtaining superheat there.

you can obtain an inexpensive air meter from Dwyer to learn the art of checking static pressures, air velocities, air volume. Dwyers' 460 meter is well worth the small cost to learn the skills. ...

ya got an unloader on that compressor? if so, perhaps your oil has found an escape route through the unloader. just a thought

thanks bl, i was thinking the same thing, wasn't sure. what i am sure about is that currently, it is blowing thru and a lot of air is being 'thrashed', doesn't look normal to me.

would anyone happen to know if a
Williams m/n R62-30P1-C, s/n 24C77-AC015 condensing unit is blow thru or draw thru?

beenthere, i agree with you 100%. i felt that from the very beginning of this thread, and was hoping for jeff that would be the final outcome.

clzair, i agree wholeheartedly! when simple (working) solutions are presented in this forum, seems as if many want to keep matters complex. i suppose that is one of the many reasons why i enjoy...

just a short note on 'downsizing', the correct term to 'downsizing' is 'derating'. that said, manufacturers have established parameters to derate their equipment, it's just they don't publicize the...

now this is a very refreshing idea!

you took the thoughts right out of my head! i just have a fear of expressing all i think

in my opinion, asking a progrmmable stat to setback 1ºF defeats the potential savings of a programmable. that 1º differential may be out of the operating range of the stat, try 2-3º differential and...

dave, how old is your house electrical system? aged electrical systems with deteriorated ground is also a leading cause of 'lights dimming' syndrome. you might want to have your entire electical...

ah, bringing up dollars from circa 1954! now, that is wishful thinking! :)

29) all the above would yield little or no frost on the evap, however 'all the above' is not a choice. soooo, go with the most obvious, leak in the system. no refrigerant, no refrigeration effect....

not2, i'd take the recommendation with a grain of salt. if your compressor is cycling 'on' multiple times with no problem, i'd leave alone and not worry about it. besides, there is a second side to...

and i only thought i'd see these conditions in central indiana !!!!
