Maybe someone can lead me in the right direction here. Heat pump had been working fine and then slowly began to degrade in effectiveness. Turns out the refrigerant had leaked out. HVAC company asked about possibility of some one huffing it to get high. Anyway it was refilled back in late spring early summer. Now when it turns on, the outside unit will start and stop 2 or 3 times before it stays in all while the furnace fan continues to run. After those 2 or three initial times it stays on and does it's thing correctly. It's not short cycling, it's just the outside unit on and off and it kicks off for like 2 seconds before kicking back on not even enough time for fan to quit making noise. I have an ecobee thermostat and it is a single stage carrier. Getting low in refrigerant again maybe? Thanks.
