However; I am also considering buying a house or two somewhat local and listing them on air bnb.

@Yashar FredI have been using Beluga Air for the past 3 years for HVAC needs at my home in San Antonio.  

Hello Dario,I'm in the Air Force, stationed here in Tampa, and looking to start investing in a small multi-family homes too!

Forced hot air once the furnace is off, there is no more heat. 

How many people are running air bnbs?

And then there is Helicopter logging thats insane.. we did some of that.. these Helicopters come whipping in with a 40 foot log that weights a bunch set it down and the chocker setter has to run over and unhook it from the cable one puff of air and by by hand or diget. the fellers get hit by falling limbs and or tree rolls off the stump wrong and rolls on them.. then you have crushed legs .. my partner had his foot crushed..   

We are currently putting our first STR on Air B&B and VRBO.

The best you can do is squeeze out all the air and be prepared to sacrifice some product to the nail you run down the nozzle, it's messy. but this only make the stuff last 2/3 days longer. 

Mine is a basic install where air handler is inside the house + condenser is right next to the house. 

I have seen homes where they almost destroyed HVAC ductwork by blowing loose insulation in the cold air return ducts.
