Changed the third warranty coil for a customer 4 months ago. 2013 system. Leaky. One service was a bad txv. No help from manufacture. Customer finally installed new system. Different brand.
...
After evacuating, just charge in what is on condenser nameplate. Real simple. Most manufactures will tell you to do just that. You will not get a super or sub. Liquid line is your metering device....
Have your AC Contrator perform a heatload calc. If they cant, find another AC contractor. No guessing aloud.
Been there done that in south fl. Did not work out. Dont see them anymore. As for saving the planet? From what?

Check house breakers and fuses. Have a pro check fuses and Check wiring to comp.

Wow. Another something I thought I'd seen it all moment. Gotta say it again. Now I've seen it all.

Thx for that. Looking to invest but I'm old school and really had concerns on those o rings. Nothing like a good flare or brazen joint. Truly time tested.

TRANE. I like the spine coil. They hold up well in our salty environment here in se FL. Recently changed out one from the 80's on the water. GE, same spine coil as its now TRANE. Installed one for...
Go with the TRANE variable speed system. Installed a few of those. Good system.
Get a heatload calculation done on the home. Always. Before changing out an AC. It's cheap insurance that the new...
Get another opion

Well you state you've had one issue. Why are you changing? Me neither.

yep. finally learned to do that after my 3rd ***** out with GC's. works everytime.
Running backwards? Had a few do those. Single phase too.
Keep a close eye on the btu results of a heat load calc. Alot of these 410 systems are under capacity, even though they are listed at a certain capacity. for example a 410 3 ton system may be...
They complain when they're hot and they complain when they have to pay. Great! The worse thing that you can watch here in S FLA is AC contractors giving AC systems away for pennies. Literally. A...
have ac contractor back out and make sure refrigerant charge is where is should be and make sure air handler is wired correctly. if not fan motor may not spool up to capacity.
try turning off power to the system and reboot. power meaning system breakers in house electrical breaker panel.
Call the service co. Make sure the transformer is has a large enough VA and make sure it's tapped right for the supplied voltage to the unit. Sounds like a low voltage issue.
I see. Now I must think what caused the compressor to fail. No preventative maintenance? Power surge? Bad start component? Pests? (Hard for customers to believe a lizard or ants can take these...
Leave it at default.
I find it interesting that all of a sudden, you have an interest in refrigerant charging charts. Interesting.
Which of these 3 companies performed a heatload calculation to give you those type of answers?
Jujitsu? Haven't heard of that brand just yet. Where can I get one? Sounds tough.
Read your manual for the controller. Dont have it? Go online. Carrier makes it very easy to find their manuals and literature. Just input your controller model number into carriers search engine...
And why is Labor more expensive? I did not see an answer. I saw you learned a lesson. As a contractor, I want to know what you learned so I can pass that along, to save my customers $$$$$ Thanks.
older guys? Im an older guy and i was taught to "burp" the hoses when they are pulled off the ports. Now I use hoses with non bleed adapters. Us older guys aint to happy with all the regs put on...
Heatload calc or your going to just extend your problem for another 10-15 yrs
Check to see if the system your installing is an inverter type as most mini splits are. They have a working btu "range". If the system is slightly oversized, in this case, 3000btuh which equate to...
Wow! What a scary looking job! Where is the Auxillary Pan? when that primary drain in the cooling coil plugs, water is going to drip onto your new ceiling. I would strongly advise an auxillary...
Go with your gut? What? There is a huge discrepancy between unit sizes, and obviously this homeowner has not had a professional heat load applied to his residence. Talk about walking into a...
Goodman AC's are made in TX. Installed many of them with 0 problems. Come with a 10 year warranty on parts. 99% of problems with AC's is the installation phase of the AC. There is no end to what...
Your Return flex needs to carry back 1600 cfm. Consider an 18 - 20 " flex size as your return. If you break it into 2 returns, go with 2 14" flex ducts. This keeps the return from starving the AC.
Hot gas getting by?
No
stay at 800
so if blower is delayed off and is ramping up, and the compressor is not running, what happens to all the moisture on the evaporator coil and in the drain pan? it reevaporates back into...
A high Suction Temp
anyone the btu for a 750 sqft glass cabin? get a heat load done or you may be sorry. there is no such thing as rule of thumb for ac installations. period.
Your first issue is you have a mismatched system, so who knows what your getting with capacity and efficiency. Goodman does not engineer their equipment to work with lennox and same goes for lennox...
make sure your contractor registered your equipment with carrier, or you do it, so you max out on the 10 year parts warranty. if not registered, you only get 5 year warranty on all parts.
I agree with Baldy. I have installed a lot of Daikins, not so new here is SFL.
If your airflow speed through the evaporator coil slows down, your temperature will also drop. Slow air flow across the evap coil can be caused by dirty filters, dirty coil, bad evaporator fan...
what is the rule of thumb, for, say, a glass house? If you load your house correctly, then you'll have your answer. I load up houses to and sometimes, am surprised by the calc. Then really...
Not sure where you are located, but in FL, you do not typically need an electrical permit to changeout an AC. As far as the contractor goes with those stipulations, welcome to our government...
Do u still have it. Go sale? I have book. But no tool.

Have LG system setup master/slave. Receiving codes ch 25(over\under volt limits reached) and 212(slave unit inverter PCB error. System shutdown). How is it determined if it's the master or...
Exactly
Give it some return air. Unit cannot breathe
Customer called me out for first time for look and see. Got there and then I saw. More of S FL wiring condenser fan motors. Someone failed to tell the lazy crack tech that the wires aren't rated...
Try sealing the base around the air handler with caulking if the air handler is sitting vertically on a return air stand. The air handler may be sucking in raw(untreated) air around the air handler...
