What difference does it make to you if your tenants smoke outside in the open air?

I also have an Aerospace Engineering background but haven't finished my degree yet due to my service in the Air Force.

Being a current military member the air force offers up to 9000 for a one time certification.

By doing so, you can advertise it as having NEW, ENERGY EFFICIENT, appliances, water heater, heating and air conditioning.

Yes have a plumber who can do an air test check it out for you.

There are lots of active, seperated or retired military on here my self included ad air force.

Steve,We have removed three chimneys in the past year ... and there is one more on our "we could make better use of the space" list.If your gas furnace is a recent, high-efficiency model, you should be able direct exhaust it out through the wall using {C}PVC piping ... you may be able to direct vent it as well so it's not sucking warm air from the house for combustion.We demolished all three of our chimneys on our own (myself one one, along with my "handy-man" on the others).

Does anyone have any good resources on the energy use of various window air conditioners?

I got out of the Air Force last summer and started investing while I was still on active duty.

Milton is a large air base.
