I am looking at a job where I will be doing a changeout of the furnace only. The job is a split system w/ Trane condenser. I want to know If anyone can tell me the size of condenser by these #...

If I could give you a bit of good advice- I have experienced that Payne units can be a real nightmare. It is just my opinion, however I would'nt have one or install one. I think Payne is a Bryant...

i use hvac calc 4.0 it also sizes ducts besides doing the heat loss/ gain calc. it is reliable for getting the right cfm's where they need to go. You just have to make sure you input the data...

I am experiencing something very odd that I have not seen before. I live in NC . I am getting a black dust buildup on my pleated air filter. I put a new one in and a day later I had the same thing....

Yes, the compressor was bad. as I said in my initial post, the side of the comp. was burnt and melted. Caused by the shorted wire. I believe the Gfi tripping was related- though I am not a...

I removed the comp. this morning. I removed the old wiring and in the process discovered that a wire going from the comp. to the capacitor had been resting on the ref. line and burnt through the...

It figures if it's stupid and inexplainable, it would happen to me, Not that I have a monopoly on mech. problems, but It is disheartening since I use Rheem so much- thanks for the response! at least...

Not a burnt terminal- a large burnt spot on the outer casing of the compressor- it melted the metal tag.

I installed a Weather King Heat pump a year ago.It Was tripping the breaker so I checked it out and the Compressor was fried. It has a large burnt area right at the motor. This is the first Scroll...

I have a customer who wants a humidifier installed on his heat pump system. The air handler is in the attic. Freezing is a concern. I am thinking of mounting a plenum in the garage , running a supply...

What was freezing up? the indoor coil, or the condenser?

A boiler will last up to 50 years if maintained properly. ( I have seen some last longer than that.) Find yourself a well qualified company that works on steam systems and they will be able to fix it...

I changed the air filter and the indoor coil looks ok- no air flow restriction. The pressures seem ok to me- other units I've serviced have worked fine at those pressures. When I originally went on...

How big is a pretty big house?

Just moved to NC and started servicing heat pumps. Ran into one today that is icing up ( outdoor lines and inside of the condensing unit) Checked charge when running- 150/60 What might be the cause?...

I lived in nw PA. You wouldn't even consider a heat pump there. I live in NC and I hate my heat pump system. It blows lukewarm air when it gets below 30 deg. They only work good above 30 in my...

Is this a tankless coil in your boiler? The best way to go is an Amtrol boiler mate indirect water heater. They are way more efficient than a tankless coil will ever be, and way more efficient than...

I favor Rheem over the other brands. Very reliable and long lasting. Accurate Size can only be determined by doing a Manual J Heat gain calculation. Alot will depend on the make up of your existing...

Many people replace their car every five years, their furniture and appliances more or less often, 15 years is in my opinion, past the due date of replacement for a heat pump. They work hard during...

I agree, the question really seemed unecessary to me, I think it is one that very few get correct so they keep it in there to keep the pass % down.

Answer I got from member:
below comp. temp because pour point is temp. at which oil gels. Sound good?

The exam question read:

What is the pour point of refrigeration oil:

above compressor temp
below compressor temp
ambient air temp


I believe they are looking for the...

Is this 2 stories plus basement? that is what I think you stated. Anyway, the most important issue that prevails is proper sizing and then location. Sometimes the size of ductwork required will...

I have serviced alot of units but I haven't had many service calls on Rheem units. Yet there are alot of them out there that says something I think. I would go with Rheem, in fact I did for my own...

what is the temp. pour point of ref. oil ? A recent heating exam question in NC

Recently took my NC HVAC exam and was asked: what is pour point of ref. oil and what is function of trap in suction line? I was stumped, any help? I work with mostly residential so I don't face these...

It sounds like the humidifier is hooked up properly. The duct is going to the supply like it should. Some units are reversible to make ducting easier. Your unit should work fine as installed.

A 22 year old furnace- I would replace it immediately, especially since it has been put through so much abuse. You need an accurate heat loss calculation and duct design. it sounds like that furnace...

What is the purpose of the trap in the refer suction line?

It is never good to have a induced draft furnace connected to the same flue as a water heater. both should have separate liners. If the chimney would become obsrtructed for any reason the furnace...

I recently took my NC Heating lic. exam and was asked what the pour point of ref. oil is. I wasn't sure. the choices were: above compressor temp, below compressor temp. or in relation to outdoor...
