My wife and I feel electric is more dangerous because the surface could be hot long after you turn it off and you are more likely to burn food because you cannot control the temperature as well.We see valid points on both sides of the argument so would like to know what you all have in your rentals and for what reasons?

Now that I have begun researching real estate investing, my interest in home rehabbing has only grown and I could say Im willing to leave the safety of my welding job in order to gain the skills and knowledge of the contractor field.  

I suggest you check the temperature in the house near the a/c. 

For the thermostat there is a temperature minimum in winter in most locations.

Unit 2 gets very hot, even now with temperatures cooling. 

Seasonal RE activity has begun, vegetation is Green, Bluebonnets are blooming, temperatures are moderate. 

For many technical reason, these digital sensors all work better at capturing light at daylight temperatures than at the more common warmer indoor lighting temperatures.

 - One interior unit will be 12,000 BTU for a large living room/kitchen space, and a smaller 9,000 BTU for the bedroom.the total system capacity has to be able to cool both inside units at the same time so 21,000 BTU or larger for the outside unit.The beauty of these is that they can be installed DIY (provided you get your 608 certification card), as long as the line sets don't need to be shortened or lengthened, as there is no brazing/welding involved, just connect the lines and purge air, etc.my dual zone costs comes in at around 2.6k to 2.8k for my 800sqft structure.

Its best to speak to local Flooring guysit important to take into consideration the year round temperature. extreme difference between winter and summer can also factor into the choice Best of luck
