Default HVAC Question

I am in the middle of an install of a new HVAC unit in my upstairs. They are installing a york pv9. They are installing it on its side is that ok, and also they are installing it in the attic? The documentation says somewhere the temp stays above 32.

I know there are some experts on here is this unit ok to install on side and attic?

Most all residential air handlers these days can be set up for upflow, downflow, horizontal right, or horizontal left operation. Attic installation is routine. Make sure your HVAC installer hooks up both the primary and secondary condensate drains. They should be plumbed to the outside through p-traps. There should also be a drain pan under the unit. I prefer those to have a third drain or a water alarm, but almost nobody does that unless required by local code. It's triple protection against a condensate pan overflow and a ruined ceiling. The secondary takes over if the primary drain gets plugged. You are suppose to observe water coming out of the normally dry secondary drain pipe and know something is stopped up. If the secondary gets plugged, the drain pan is the last resort.

Installation sounds fine but you may want to think about installing a cut-off switch to the pan in case of blockage on the condensation line. That way if water quits flowing out it will shut down the furnace and save you lots of headaches and money.

A lot of furnaces these days are multi-position. They are usually one of these configurations: Upflow/horizontal left/horizontal right *******downflow/horizontal left/horizontal right. As mentioned, make sure the overflow pan has a safety cutoff float switch installed/wired in. Attic installation is very common.
