It tends to show up more in the winter months when moisture inside the home condensates around windows or exterior walls. 

You’ll see more condensed urban housing along that corridor soon.

Furnace ac coil outside condenser water heater copper everything replaced it all put it on the market cane time to show it to the crackhead tenant yes I do say crackhead tenant sec 8 and came into the house everything was missing again even though I was there the day before and yes I said day because I won’t go there at night.. it’s not the tenants it’s the HOOD go to north county castle point if you want to make money walnut park is a cesspool

A steel enclosure over condensing units, and refrigerant locks on r-22 units, are common.

I'm not sure what we're going to do about pulling equity out now that the economy is in the situation that it's in, so I thought I would post an update anyway.When the tenant went to move in, the property manager found that the (brand new) A/C condenser had been stolen.

However there were so many listed I’m wondering how best to condense these options and choose one.

I would check your gutters ASAP and then the furnace condensate pump.  

I would think about 10k to 12k should be a reasonable price to do all the duct work, condenser, air handler.

Condensation coming through the soffit collects heavily around the point of freezing and will thaw during the middle of the day and is starting to drip through my ceilings and vent fans.

You can see the condensation coming from the ceiling.
