Based on what standard? What do you say when it's 19°. personal experiance,lots of years servicing equipment [^]if its less than a 20 degree drop i start checking pressures and temps on lineset

Id like to see atleast 20-25 degree drop across the coil on any cooling system myself

Sounds logical to me,that definately calls for replacement [:-bigeyes

[:-tong2]

See if you can find someplace that rents a smoke machine and direct it up each vent while somebody watches the roof vents. My guess would be they installed autovents/trailer vents inside the wall and theyre not working

Forget the 5-amp thing. It's meaningless. Just go by the data plate. With an air conditioning compressor -- as with lots of large motor loads -- the compressor motor itself has overload protection built in. That'll protect the wire from overloads. The required breaker is only there to protect against short circuits & ground faults. Why then, you may ask, does the size of the breaker matter? If it's only there to protect against faults, wouldn't any larger breaker size do? And if you were to ask those questions, they'd be good ones. The answer is that smaller breakers have steeper trip curves, even for faults, so they provide slightly (ever so slightly) better protection. - Jim Katen, Oregon Motor wiring is supposed to be sized to 125% of rated load,10gauge wire is actually a little less than required but most inspectors would accept it.As far as the breaker size if it is just used as a disconect in the box outside by the unit it doesnt really matter if its oversized,the breaker feeding the circuit in the panel is what matters.

Are you sure its not suuposed to be wired to a 240v circuit?By the time you figure 125% of the load for the wiring youre looking at 39.05A even at 120 v which requires a 40A circuit and #8 wire,i dont remember ever seeing a 40A single pole breaker in my daily travels anyway. If you run it on 240V you could run it on a 20A 2p breaker with #12 wires feeding it []

Depends on whether hes installing a new 410 unit or a new r22 unit,their are still new 13 seer r22 units out there. I talked to my salesman at the supply house the other day about the differances between 22 and 410 coils,he told me most of the new ones are able to be used on either system

those are full size breakers,just tandem is all.

Depends,is it just the panel or a whole new service?Finished basement,how much repiping? I can do a simple panel upgrade for $600.00 if nothing else is required for average 100a service if nothing else is required,but if theres more work its more money

I know my word skills really suck,but can someone explain that one to me? [:-monkeyd

Yep they used aluminum dryer duct and vent to heat/cool room in basement!

When replacing an ungrounded outlet you normally are required to replace with same style or a gfi

Id say thats the probable cause,I wonder if somebody removed it at some point?

Click to Enlarge 33.95 KB couldnt believe they used 4" aluminum dryer flex for ducting,but then i saw the dryer vent on the wall inside bedroom! [:-monkeyd

heres a few shots from a no cooling call this afternoon,i finally couldnt take it anymore and sold her a new heatpump and coil! [:-weepn] Click to Enlarge 58.12 KB

looks like some sort of limit or roll out switch,definately bypassed

ditto!

id say no! [:-tong2]

just wondering if anybody has building drain and sewer camera'd as part of inspection?

You can overload any kind of wire by oversizing the fuse or breaker,I come across 14ga romex all the time on 20a breakers and 20-30a fuses when im out running service calls [:-party]

No problem,back to the war on code violations! [:-thumbu]
