I was going to say that low refrigerant in your system can lead to the unit blowing very cold air, but when that happens, your evaporator coil eventually freezes up and then no cold air will blow in your house. If you want to check your coil to see if that's what's happening, check out this video:Just need a quick advice: for the last several days, I sense that our HVAC system is - surprisingly - cooling "way too much" (it's 90+F outside, but the air coming to our house is really cold). We haven't had our annual summer maintenance done yet (coronavirus concerns) - so we just scheduled that for Tuesday. But, in the meantime - any ideas why this may be happening (other than me getting sick and feeling imaginary chills)?
Importantly - there are two pipes at the base of our unit - one (thicker) is tightly wrapped in insulation, and I *think* that one is cold. But - the other one (more narrow, copper-colored) is always warm - is that the correct way? (I know nothing about HVAC, obviously...)
Ironically enough, the video - which I found while looking for a shot of the A coil to show you - goes on to say that an oversized condenser is the guy's issue.
