model hp24 installed 1993..system has been flakey for about a year or so..both cooling and heating ..sometimes good cool air ,then nothing..same in winter, heat sometimes other times not..now compresor wont start..just replaced the cap (old one puffed out...swollen you know...system also has a kicker..
contactor(replaced along with other relay about three years ago) engages and fan comes on but no comp.
what should my next step be..put gauges on it ? jump contactor and try to start comp...change out cap again ...what will stop a comp from starting??? coils are clean and good airflow...
thanks for all you advice in advance..
