I’m beginning to wonder how ‘harmed’ we are in our little 900 square feet condo! Although multi-family is typically more expensive, does it really make sense to have a $300 energy bill for this postage stamp…? 
 
It doesn’t help to have a west wall made up entirely of floor to ceiling storefront windows, I know, but we have occupied units below us, above us, and on one side. The other two sides…emergency egress stairs and storage units/parking garage. 
 
The air handler is definitely NOT multi-stage and when we do run it, it is constantly on, off, on, off… At 3 tons, it is even oversized for the 500-600 sf per ton. Yikes!! 
 
My next step is to run the Manual J load calcs to see just how ‘oversized’ it is. And then, I’ll alert all the other residents!  
 
Stay tuned…I’ll post my findings

That is so great to hear!! That builder really harmed that homeowner from a comfort, energy, and equipment maintainance perspective. And the equipment likely is not multi stage so this imbalance is probably going to be quite noisy and pronounced! 
 
When the equipment IS balanced and has range it can keep running, counterintuitive but actually the best way to schieve comfort, iaq, and maximum efficiency.  
 
KEEP UP THE GREAT WORK!!
