I believe the grill is an integral part of the condenser and can’t be replaced.

Don't be afraid to unplug the fridge and take off the cover (sometimes cardboard) on the back at the bottom; usually you need a 5/16" nutdriver, and sometimes that gives you a good shot at the condenser coil.

Her side of duplex needs new A/C condenser.

The house was old, dated, dirty but with a 5 year old 40yr roof and 1 year old 93% efficiency condensing gas furnace (and beautiful hardwood I found under the 40yr old carpets).

The inspector decided decided to write me up for an electrical whip to a a/c condenser that had come loose. 

You can also consider a combo washing machine/condensation dryer.

Is there a way to condense the two mortgages to one or is there a better way to make this situation more manageable.

Once completed we go ahead and remove the water tank, A-coil and condenser unit and store away for safe keeping's.

@Ram V.I do Hvac for a living, usually the bigger the company the more they will charge , take into account equipment brand , the size of the condenser seems about right for the square footage of your home , usually 2 stage furnaces are more expensive I would go with single stage you won’t be saving that much money anyway , ballpark pricing on the equipment would be 1400 for condenser 400 for coil and around 800 for a single stage furnace , that’s cost remember contractors raise the price of the equipment and of course you gotta pay somebody to install it right .

Most of the manufacturers you can only use their thermostat and their "smart" thermostats aren't typically that great.Pay attention to condensate (the water produced by the units inside and out).
