LRA on the data tag stands for "locked rotor amps" and has nothing to do with tonnage. In the model # there should be a number to use. And divide that # by 12 (12,000 btu/ton). So if I had a PFG24H200 it would be the "24"and a 2 ton unit
You may have a problem with the reversing valve. How cold is your location? Do you also have electric back-up heat available in case of extreme temperatures?
Hello RR Hard start can't hurt BUT dosen't sound like the problem.Do you have a scroll compressor?They don't need a kit.Does it start every time?It could be short cycling on LOW PRESSURE SWITCH.If the unit is (pumping down) during the run time you have a restriction in the system.Make sure the service valves are open ,do you have a filter dryer colgging up or a bad TXV valve also could cause short run times.20-30 PSI the switch cuts out.
i would check the capacitor( shiny little round or oval can) if bad get an exact replacement(mfd and voltage) if it is good i would try adding a boost capacitor(increases starting torque by 300%)
Better off taking good money and put into something with a warranty. its probably a 4 hour job to recover solder in new valve change drier pull vacuum recharge If your system is freezing up it may not be the valve could be a check valve. low freon dirty unit all would cause the unit to freeze up is the company competent in working on heat pumps don't get some body that can work on you want in FIXED . from what you said in your 2nd post i am not convinced its the valve. Tom p.s i am in the mid west prices are not too far out of line.
check the true psi with the line psi to see if same if psi is good in cooling 225 hi and 70 low on 80'day then compressor is fine and i would start checking for temp difference on the reversing valve sometimes this will cause high suction or high discharge psi shift it manually with by energising it be cooling or heating then pull wire and see how it shifts if shifts good then txv on out door unit could be bad what is the psi in heating on the discharge line going to the indoor unit? most prv's are set at about 350 psi r22 as for suction line size its only hot gas in hp mode os no problem their shows in cooling mode as low suction psi ..hope this helps some also make sure indoor coil is clean!....thanks & rate me
