Formula to calculate rating of capacitors in
It's not fixed formula, but as per basic rule, easy method tocalculate for motor capacitor.
(2650 X full load amps) divided by supply voltage(mentionedin capacitor)= MFD. (Plus or minus 10% to 15%)
Ex: 1 Tr which gives full load amps of 6 amps (2650 X 6)=15900 divided by 240(VAC)volts=66.25MFD
(10% to 15% plus or minus) You can fix 56.32 mfd or 76.18mfd
So, you can go in between 56.32 mfd and 76.18 mfd.
If you calculate of 440VAC capacitor, it will be 36 mfd.
Hope, it will be helpful . Thanks.

My heat pump is shot and is operating off the
You mean you are using the Emergency heat setting instead of the heat pump????...You're using Natural gas only now tn emergency heat????That's fine...I wouldn't replace a heat pump if you have Natural gas....it's too expensive compared to Gas....you may be able to still use the heat pump as an Air Conditioner only , it depends on what's wrong with it...otherwise you will have to get a Central Air unit instead...cheaper and just use the Gas for heat

Why does the air conditioner works fine but no heat
A bit more info would help - like "nothing as in switched off" or "nothing as in motors all running but nothing gets hot".
If you mean that it all sounds and looks as though it is working but there is no heat, then it is possible your changeover valve is jammed. There is usually a four way valve which effectively decides which way your a/c is going to be pumping.
Other reasons are that on this model, it checks to make sure there is at least a 5C difference before it will try and work.
For more help, please be a bit more descriptive as to what it IS doing as well as what it is not - eg: fans / compressor on? strange noises, hissing / error messages and also indoor / outdoor temps
