In my case (rental), I had the luxury of time where I could go back the next day. I was sure glad it was not on the evap side since air handler was in a low crawl space doing a belly crawl.

I’ll throw this method out there. Just finished up a split system that had a major leak. I pressurized the sys to 100 psi and then shut both service valves and then went back the next day. Checked...
8000w at 240v is around 33 amps. With the air handler at 15amp, 60 amp circuit probably not overkill.
FPE didn't go out of business because they made good crap. I get rid of their stuff whenever I find it. The price of a replacement breaker costs more than a complete GE panel
Choclair,
How about with the furnace off, turn on blower at thermostat and use some sort of smoke to see if you can detect a draft from the HX openings. That should confirm any openings in the HX
In the drill department hard to beat a red Milwaukee
Around here, a non-fused switch is used for the 120v feed to the furnace/air handler. That circuit should already be protected by a 15 or 20amp breaker.
As far as the GFCI, I would be concerned...
Was the evap coil replaced with the condenser unit? How old?
When was the last time evap was cleaned?
Is it a fixed (cap tube, piston) or a TXV?
Make sure indoor vents are open. Too many closed...
I have always questioned how much air a turbine can actually move. They seem to be nothing more than a circular propeller sticking up in the air. Now if there was a small fan blade on the other end...
Manual J will definitely get you thinking about building construction methods/techniques as they relate to energy conservation. If you are willing to invest the time it should more than pay for...
And vice-versa.
Might as well measure the discharge line temp close to where it comes out of the compressor.

I know that TX and FL reciprocates with GA but not sure about SC. Try checking out GA website to see what they say.
Now that Obama will keep sending me my unemployment check I wouldn't either. However, if my little Suzy was hungry I would rethink that one.

30yr old Rheem builder grade (El Cheapo) condensing unit, 4ton.
A hard start kit was added last summer as a preventative maintenance thing. I believe it was one of the better Supro units. Anyway,...
You might want to install an access fitting on the suction line at the evap and then compare it to the suction pressure near the compressor. Might give you an idea if you have a restriction or...
For what's it worth, an ECM motor is also a very expensive motor when compared to the proven, simple, been around for ever, induction motor. About 7X more expensive.
Just to be clear, we are talking about changing the size of the heat exchanger but the expansion device is still precisely matched to the compressor/condenser capacity.
Both switches are important bells/whistles that are normally found on the deluxe units. As a slumlord I consider the high psi switch more important but the low psi is also of value. These switches...
Still trying to get a handle on compression ratio with respect to refrigeration. On an internal combustion engine, compression ratio is maximum cylinder volume divided by minimum cylinder volume....
I was actually surprised at the thickness of the shell on the old recip compressor. Chewed up most of the cutting wheel to get it open. It would make one hell of a "pipe bomb".
On a hot day...
Correct, no doubt it will not be a 13SEER system, but they are right back to where they were before the old compressor took a crap, at a minimum cost. Not sure about any 8SEER still out there, 10SEER...
A few more points before this thread goes away.
A properly installed R22 unit, for the most part, should never need any freon added during its life.
In TX, condenser change outs are common...
Older (approx 30yr) Rheem 10SEER a/c unit, 3.5 ton.
Recently, during residing, discovered the suction line had been crimped down to approx half of its 3/4" diameter. Probably happened when the...
That is true this week but what about next week or next month or next year. Right now, most electric generation uses nat gas so if gas someday goes thru the roof then electric rates should follow...
I have a similar situation but deciding is a little easier. I have a 3.5 and a 4 ton unit still in service going on 30 yrs, Rheem units that NPC installed when they built the houses. NPC didn't go...
Until such time the lint build-up catches on fire. A fire starting in the dryer vent is one of the more popular ways of burning down a house. Dbl wall pipe is probably not overkill.
Sounds like the house is fairly well sealed/insulated but other heat generating sources within the home must be considered. Figure on every BTU generated by the house chef on the stove/oven or all of...
Two big beer boxes in a Wal-Mart parking lot built/insulated exactly the same way and have the exact same heat gain down to a gnat's rectum. Box #1 has a 2t unit that runs continously but maintains...
two exact same cars travel 100 miles. Car #1 drives there at a steady 40mph and gets there in 2.5 hrs. Car #2 goes like hell at 100mph but he stops to have a beer every few miles and gets to the...
how about this. reroute the condensate drain to drip over the liquid line where it comes out of the coils and from there let it overflow to drip on the hot gas line out of the compressor. the energy...
Why did the fan stop running? Was it because of a low voltage caused by the short? Or did a dead fan motor cause the compressor to overheat. You might want to invest in a second opinion before...
TPoz,
So what did you figure out. Will you pursue the HVAC trade?
I've always heard that heat pumps really start to peter out around 45° but the newer stuff may be better. The minute those resistance heat strips kick on there goes about a years worth of energy...
Had a wallbanger once that the fan would run normal until the compressor kicked on and then the fan would turn backwards. It had one of those combo run caps and one side of the cap had burned and...
Assuming your house is plumbed/available for natural gas, why are you considering a heat pump?
In most states the contractor license number should be displayed on the vehicle. Includes electricians, plumbers, HVAC, etc, anyone with a state contractor's license. Guess it doesn't keep someone...
Back in the old days people would add storm windows to get the double pane effect. Not as efficient but a lot cheaper. Another trick for windows is to use plastic and tape to make a crude double...
Here's another consideration. If you like to bake a lot of cookies, cakes, etc realize that just about all of the heat/BTUs going into that oven or stovetop eventually has to make its way thru the ac...
Some of us in TX run wall bangers to get thru the nite and then during the day hang out at Wally World, riding around on one of those electric carts. At least until I find another job.
As outsides temps go higher, that ac unit needs to work harder to get the same job done. 100° in IAH is not normal and sounds like your unit just can't keep up. If you believe 100° is becoming the...
I'll bet somebody was "maintaining" the girls.
If it's always been a rental there's a very good chance that the indoor and outdoor coils have never been cleaned since installation. Slumlords don't...
you might consider an attic ventilation fan. they don't use much KW but they move a lot of hot air. be sure to have plenty of soffit vents or it may actually suck air out from the conditioned space....

I have a few rent houses that I would like to make idiot/tenant proof as much as possible. I installed a builder grade Goodman condenser last year in one of them and want to add encapsulated high...
