My name is Chris Battilana and I am a 29 year old Commercial Heating Technician with aspirations of owning a large real estate portfolio by the age of 45.

A/C and heating coils may need replacing.

Be sure the furnace is serviced every heating.]

I've classified the heat map as dark green = D, light green = C, yellow = B and pink = A.  

Instead, mix a solution 50/50 alcohol & water or vinegar and water.I'm in Calif and the house has a Western exposure w/o shade, so to reduce the heat load, we added a tint to the outer pane which reduces the light transmitted into the room.

Note I'm not contemplating repairs / maintenance type stuff, such as sewer mains or 1) Moving a home to a new location (as in so expensive you're nuts to contemplate it)2) Replacing / significantly changing external look / structural elements / adding a story3) Replacing vinyl siding with full brick or stone all the way around4) Replacing old heating (baseboard radiant) with new, such as a heat pump and forced air5) Updating Kitchens6) Updating bathrooms7) Replacing floors (like carpet to hardwood or stone)8) Updating fixtures9) Painting

With insured loans, the issue is when a section of the house, usually a converted attic, lacks a "permanent heat source".

James,We do this, but give gift cards to local businesses in the neighbourhood: restaurants, pilates/yoga studios, cafés, etc.  

The chimney is either letting cold drop into the house,,,or shipping heat outside by the natural rise of heat.Furnaces /boilers with pvc venting dont. 

The unit has been unoccupied for 2 years and the AC/heat was completely turned off.
