why can't you do central air and heat?

Have you talked to your Condo board about this? you're going to need approval anyway, so see what others have done.

Check out mini splits. They heat and have a.c.. just not sure if they would be allowed by your condo association.

The condo board will need to be approached to see what is allowed. I think the mini splits might be possible but you will need to check . Central heat would have needed to be installed a long time ago not really feasible now.

900 sq ft is really small. For that reason it's probably in your best interest to install a mini split heat pump. I would choose an inverter based one. (Namely because they come in smaller sizes than a split forced air HVAC system would also duct work in your case would be very difficult if not impossible. -- simply not enough room)

As others have said, your HOA will be the deciding factor as to what is allowed or not. A heat pump will require an outdoor unit with line set run to the interior of the apt.

A heat pump will also give you cooling in the summer.

Thank you for the responses, here was a snippet of what the property management said,

"To start out with I suggest obtaining an estimate from Heating and Cooling professionals. They can determine what the best options are for the unit. Historically full HVAC units have not been installed within the HOA’s units. I believe that an HVAC unit would have to be installed within the unit’s balcony area which would not comply with the maintenance requirements for the balconies."

So it sounds like anything that doesnt stay within the confines of the unit is out.

Thanks,

Your HOA's property manager has given you some guidance. Bring in a good local HVAC contractor who has worked with condos in your area. You can also check with the neighbors to see what they have done.

You need to maximize your insulation.

I have seen the air con units on condo balconies so maybe try that idea with the board they really are not that ugly and can always have a plant in front of it .
