A new condensing boiler may be your best option.Mini splits are cheap enough and easy to install.

Although it was 3 years old,, So life of a window A/C is maybe 5 years, so it's up to you, but realize it was close to 50% wear and tear life left, the weep hole was probably clogged and that's why the guy drilled a hole in it because condensation was probably building up and spitting or dripping inside. 

These associations usually have condensed versions of the local rules with helpful explanations available for members, as well as approved and updated local forms.  

There was some mold in the closet being caused by condensation from the air conditioner.

After demo, we discovered some issues such as the furnace, condensing unit, and some ductwork had to be replaced (roughly 6k).  

I have had people look at the furnace to see why it does not blow hot air thru the vents ,it had been suggested that since the intake air vent is also located in the ceiling with the vents is the cause but no suggestion how to remedy that,I was also given the suggestion to insulate the space between the ceiling and the second floor unit,this is a condo complex,I did that but it has not proved to change the outcome of the production of heat,I have to say that the unit is on the first floor also has a very big three window side that is north facing and no building on that north side to block any of the cold north winds ,this is an old building converted to condos in the early 1990's ,I come to find that there is no insulation in the walls at all, so I know that is not helping hold any heat in the unit.I have installed ceiling fans on the suggestion of another person saying that would help..Okay the point is there is an element that is not working ,unplugged,not getting hot ,or whatever the case may be,the last person who worked on the furnace said that the blower motor was tripping the circuit so since he could not find a blower motor and ordering it would take 3 days so he used a condenser motor saying that it would be ok, but the tenant say the blower stays on longer and still does not produce much heat ,at my wits end and need to know exactly how to handle this heating problem without tearing down walls .I have went to home depot's service desk to get someone who is able to get me the right answer to this problem, I have an appointment on Monday can someone tell me what it takes to replace and element in an electric furnace,is it hard ,is it simple is it expensive will it help,can the condenser motor stay or should the motor blower be returned,is there anything I can read up on for more knowledge before Monday..Questions Questions Questions....

You'll get the condensed version.Manager: "Mike, why do you care about putting in insulation and making the place energy efficient?"

Now....were I to hold onto it for 10 - 20 years, even if I sold then, I am likely looking at exterior paint again, perhaps new privacy fence and even roof and condenser, appliances etc.  

The more condensed and urban area is north of the river and the about-to-be-gentrified area is south of the river (where this property is located).

For example, in conducting a high level due diligent assessment of package rooftop units at each location, we were altogether surprised by the deficiencies and deferred maintenance encountered during our assessment of the rooftop units given dirty air filters, worn fan belts, rusty and plugged condensate drain pan openings accompanied by condensate backup leaks down into the structure below mistaken for a roof leak by the building occupants inside, etc.
