Bristol H29B28UABCA 2.5 Ton Compressor

Currently I have a Goodman A/C unit that my Bristol 2 1/2 ton compressor has failed me. Can I replace that compressor with another Bristol compressor with the same part number but a 2 1/4 ton compressor?

The correct answer is YES and NO, yes you can physically do the change out, but if you A/C is or was border line of being the right size, and now you are putting in an even smaller compressor,then NO you will not be happy with the end result.

Did you say "The same Part Number"?

If that is so than the compressor you have is the correct replacement.

Where did you get the rating of 2 1/4 ton? That is what does not fit.

2 1/4 has to be a typo

hvac5646

Think so?

Sorry...I meant Model #. Here is the description from the seller:

"BtuH Capacity @ 45°F Evap.: 25,200; CCH: No; Discharge Conn.: 1/2"; Height: 14-1/8"; Mfg. #: H29B28UABCA; Mounting Centers: 7-1/2" x 7-1/2"; Relay: B12-347; Run Capacitor: G21-921; Start Capacitor: G22-014; Suction Conn.: 3/4"; Tons: 2-1/4; Volts: 208/230-1;"

Same model number as the old one?

That 2 1/4 tons at a 45*F evap has me worried...25,200 btus is a ;ong way from most of the nominal rating I have read. I have seen some wholesalers who sold ac with ratings similar to the rating you post...and they touted it as a 2 1/2 ton (buyer beware) system,

If that compressor is listed with Goodman as the correct replacement ..than go for it.

More info could be provided if we had a outside unit model number and inside coil number.

Outside model # is CK30-1A (Goodman)

Little on the aged side....no?

jcljr166

Yes it is.

beenthere

The H29B28UAGCA at 45°F evap 130°F condensing temp is 28,2215 BTUs, atr 45°F evap and 100°F condensing temp its 36,230 BTUs.

That is from Bristol.

You putting a Cooling txv on? What you are going to put in is for cooling txv.

Wasn't paying attention before but the OP post the height of the comp is only 14"...that seems short to me.

In a larger condenser foot print that comp was probably used in higher SEER
units.

But a Bristol is still A Bristol.....and it sure ain't a Copeland.

hvac5646

It's an existing system.
The Janitrol CK30 seires...I remember buying those units for economy jobs. That model used evaps with fixed metering device. Very few TXVs were used (at least here) because of customer apathy to energy savings or financial reasons.

Don't forget if installed with a Evaporator coil with a TXV .You will need start assist. (That's a potential relay and start capacitor). Due to most TXV's close when the system shuts down.The compressor is starting under a load (not equalized between suction to discharge as a fixed meter device would) I feel a TXV in necessary when a mismatch system is installed ( 2.5 ton Carrier evaporator to 2.5 ton Goodman condenser unit or heat pump) the TXV tries to makes up for the imbalance in coil capacity Evaporator vs Condenser and operation conditions and maintain proper superheat (difference between refrigerant temperature leaving the metering device and the suction line leaving the evaporator coil) In a perfect world and what i prefer is matched equipment .But in the real world and i run across this every day in the field is mismatched bad quality installs deficient duct work and over charged / under charged
