They could tell me this and that needs to be changed or dealt with or else, and if I didn't know any better I would fall for that trap and fork over big money (yup, I sure did fall for the air filter scam).

Here are some facts about the transaction: the seller didn't disclose anything that wasn't working, my agent didn't include the ac in the repair list( on the inspection report it says the power source for forced air does not operate, the cooling system was not operated) and I don't know why.

Air sealing a rental with electric heat is very important as well as efficient light bulbs etc..

Electric baseboard is always 1:1.On top of that the unit provides air conditioning in the summer with a SEER rating of 30, which is more efficient than the through-wall air conditioner it is displacing.

It had central air added and was painted inside, also the kitchen and bath were rehabbed.

The house now has new plumbing, new and updated electrical and new furnace with central air conditioning.  

A hot water tank, furnace, satellite receiver, air conditioning unit, security alarm system or water softener, for example, could be rented by the homeowner.

In fact, on a lot of these stations, you can buy blocks of an hour or more and put yourself on the air.

Not only that, when I worked out of Ireland travelling to places like Shanghai and South East Asia to do deals I realized after a year clocking over 300,000 air miles (about 20 weeks of physical travelling between airport time and actual flying) that this was a unique form of lunacy, regardless of the profitability of these deals.So I came to fervently believe that we make our own deals, wherever we are, through vision, negotiation and hard work.

Many of the houses in the north east are old enough that chimneys may not be lined - great source of gases in the house and chimney fires.Also, while an open hearth fireplace is ornamental, it is a lousy source of heat ... you would need to put an air-tight wood/pellet/gas insert into a fireplace to make it moderately efficient.
