Alright, so after doing a few tests on the system, we’re finding that everything electrically so far up here at the condensers is pretty good. We have a new condenser fan motor, it’s about a three year old motor and it’s rated for 1.9 amps, drawing about 1.6 amps which is okay.
The compressor is rated at, let’s see, 23 running load amps (right above my finger there) and it’s drawing about 13.3 amps which is pretty good actually. We definitely want to see our compressors drawing anywhere between 60-65% of their maximum running load amps rating. So if we see it in the 60% range we’re okay. Anything above that is going to get into the range where it’s starting to get weak and starting to deteriorate in the motor windings. So we’ll definitely keep an eye out for that, but so far everything is looking good.
We have two current controllers – a 60 and a 7.5 – they’re both rating just fine. We have a mainline starter here. It’s not burnt, not pitted, so that’s okay too.
There are a couple of loose connections that I went and already tightened and took care of that. Loose connections will definitely cause problems with your system as well so we took care of that today.
Also did find some loose connections here and went ahead and tightened these up, like that, and just tightened up the low voltage connections for our thermostat wire.
One problem I do see here is that we don’t have any surge protection on the system. Especially on an older system like this – this system is 15 or 16 years old – this system is more susceptible to surges than any other time in its life. It’s getting old, it’s weak and it can’t take a power surge and be okay necessarily. So we definitely want to recommend that it get protected to save this customer some money on costly repairs.
I also would recommend a compressor saver. A compressor saver is going to do wonders for this aging compressor. This looks like it’s the original compressor of the system, so a 15 year old compressor is definitely nearing the end of its life. So we definitely want to recommend a compressor saver.
The refrigerant levels here, I’m checking my subcooling and my superheat. Not looking to be the greatest. Probably about a pound low, it’s not terrible, but it could definitely use about a pound which tells me there’s a microscopic leak somewhere in the system. So we’ll have to definitely recommend some sealant as well as a pound of refrigerant.
But we’ll go ahead and make those recommendations. Now we’ll head on inside and check out the condition of this coil.
