I was just reading some AC threads and thought I may get some insight here before I call my HVAC guy. Just some back ground for good context:
I have a furnace and whole house AC on the same air handler.
The furnace and all has been working fine. The AC unit was old and I replaced it just a few months ago to be ready for the cooling season. I got a new Google nest "smart" thermostat last October.
We just went through a few days in the high 80s and 90's. This is the first time I really tested the unit since it was installed. I noticed a handful of times that when the AC kicks on the blower will start and then stop after 3 to 8 seconds and then start up again after 1 to 3 seconds. I am not sure if the AC unit outside does this as well. I would have to be outside when it happens to notice if the AC unit does this or not. I first notice this when I was in the basement near the air handler unit when the AC kicked on. You have to be there to really hear it. If you are upstairs you really have to be paying attention for it. Otherwise you will likely not notice it happening. It does not happen every time. Right now, Its very hard to say how frequently it happens.
I never noticed this in the past. Never last year with the older AC unit or this Winter with the heat on. I think if this always did this, I would have noticed it a few times in the past.
I was planning to get some more info before I call my HVAC guy and see what he says. The Air handler is the same old one. He only changed out the condenser and evaporator with the new unit install.
It is a new install so I assume he will check it out as part of his warranty. But if he finds something wrong with the blower I assume he will say it is something unrelated to his work.
Any thoughts on what else I should be looking for and info to collect before I call him? Thanks in advance.
