I just moved into a new renovation. The unit is two stories, with two separate AC units. Both fans are blowing indoors, but neither outside unit is. The fans aren't spinning, the units aren't humming nor getting hot.
I also just noticed that my gas isn't hooked up yet. The furnace in the attic is gas, as is the water heater.
Any idea what's wrong with my AC? Probably can't get in touch with my landlord till Monday
Okay, so now you don't have to put your age in your profile. We have a good ballpark figure.
And if those units are new, you pretty much figure they worked enough to get signed off. It's probably just a setting or switch. You didn't test them before moving in? Has the place been hot this whole time?
As Sharon said re: a switch, have you checked the breaker/disconnect for each condensor? With no hum from the motor and compressor, they aren't getting power (or isn't being told to switch on.) Breakers would be the easiest and best place to start.
Just to add to what was already suggested. Both unit not on would probably mean that there is nothing wrong with the unit. Again, check the breakers in your breaker panel AND check the disconnects outside by the units. Each unit should have its own disconnect.
Some disconnects are fused and some are not. Make sure they are in the ON position.
If no one has been staying in the unit, they may have pulled the connector at the outside unit(s) and flipped it over then reinserted. There should be a gray junction box that feeds power to the unit. Open it up and see if the black plastic connector is in with the right side up. IIRC it will be labeled.
The circuit breakers and service disconnects were fine. A fuse was missing from the electrical panel on the units themselves. I wasn't aware of anything in there, and didn't bother to open it up (it's tough to reach). So yes, there are three separate things.
