How much does it cost to replace 3 ton Lennox evaporator coil located inside the indoor air handler?

I handle renting, managagment, and 90% of repairs, close is better.  

All carpet, padding, vinyl removed, then cleaning air handler and vents, chimney, dryer vent, replaced oven range hood & bathroom fans, trashed the cabinets (were 30 years old and gross by that time, anyway), sanded down all doors and trim that were good enough not to just rip out, actually sanded the interior of the fireplace, ordered new windows (old metal ones needed replacement, anyway) and exterior doors, then cleaned everything with several applications of TSP, concrete slab downstairs with gallons of white vinegar to neutralize the cat odor which you could smell once the cigarette smell abated, then used Kilz original on all walls, ceilings, sub flooring, trim, doors, everything but slab where tile was going.  

Still no way to handle the situation where I live in one unit and rent out the other.Personal Capital doesn't handle real estate or things like my schedule C realtor income at all, from what I can tell. 

What the OP may have is an air handler with straight AC and electric heat strips for heat.

How the handlers do their job is the key to deciding if S8 is worth your risk.

When I bought it, the air handler and AC unit had never been installed and literally just needed to be purchased, lines run, and hooked up to the existing duct work.

Hello - Does anyone know if management companies exist that handle rent collection and evictions only? 

I am not sure how you plan to handle rent collections but if you think there may be times that a tenant will need to pay via some non online option then having a bank in the area of the property can be good.

It depends on a lot of factors (square footage, access to attic and/or crawlspace, location of air handler, electrical service capacity, etc).
