We have a completely new central A/C system (duct issue posted separately). Sometimes it doesn't blow cool air. Apparently only the fan runs and not the compressor when that happens.
The contractor used our existing 4 yr. old Honeywell thermostat, so on their first service call they blamed it and told me to put on a new thermostat. I did but the problem hasn't gone away. The service tech for the second service call didn't show up(!!!!!!!) but told me on the phone that it's not the thermostat, that Carrier condensor's have a known compressor start problem and that it needs a superboost kit.
I do hear the circuit breaker buzz for about 2 seconds when the compressor starts (or tries to?).
I did see a post here where some opinions were against the superboost kit.
Any ideas on what to do? Is the superboost kit a bad idea? Does it affect the manufacturer's warranty?
The unit is a Carrier 38TKB030.
