There are other approaches for researching cooling, heating and ventilation companies such as: contact your regional Better Business Bereau (BBB), carry out online searches and reviews and ask the company in question for recommendations. However, all of these techniques disappoint thorough transparency. The BBB really works for the business it represents as they are just rated if the company in concern pays them a repeating charge. Online review websites seldom show all the evaluations got, and post evaluations from sources that are not always reputable. This provides a platform for business to post their own reviews and people to quickly post evaluations without the company in question's ability to expertly solve the issue. In addition, no business would offer a negative reference; only those that are very positive. None of these are perfect dynamics for customers seeking totally impartial evaluations and recommendations. It is advised to use these methods as an informed customer and consider the info source for what it deserves.

Buying An Air Conditioning Unit?
What Factors Should I Consider When I Buy An Air Conditioning Unit?
If this is a central air unit, then call around and schedule several estimates. These should be free, never pay for an estimate. Have the contractor give you as many options as he can. For instance, he may have a 'budget' line and a 'premium' line of air conditioning units. Take in to account the size of the unit, and ask about the warranty.
After talking to a couple of contractors, you will get a feel for what's important in your house. After you have the estimates, you will have a much better idea of what kinds of unanswered questions you still have. Remember, though, these guys are salesmen. Check your facts before you sign on the dotted line.

Why Is Air A Good Insulator?
Is It Because It Has A Very Low Density So It Absorbs Little Heat?
Remember there is no such thing as "cold" - there is heat, and "lack of heat". I wanted to bring that up first, so that when we talk about insulation against heat, you will know that it also applies to insulation against the cold (or, rather, insulation against losing the heat you have.)
I wanted to remind you that heat is transferred three ways - an excellent source for these is "http://en.wikipedia.org/wiki/Heat_trans...
Radiation: This is where heat is transferred through empty space, like from the sun, to the earth. This is the least effective way to transfer heat.
Conduction: This is where heat is transferred by one object directly touching another. This is the most efficient way to transfer heat.
Convection: This is where heat is transferred by the motion of a heated fluid. This is how our refridgeration and air conditioning systems work. Air can act as a fluid, because it is not a perfect vacuum, that is why you get warm when you sit in the air flow from a furnace.
Whenever you have two objects that are different temperatures, they "want" to be the same temperature, so heat from the hotter of the two will be transferred to the cooler of the two. This is the "Second Law of Thermodynamics" (http://en.wikipedia.org/wiki/Second_law_...
So - now to your question; why is air a good insulator? The better question would be why is air such a poor conductor. Everything, other than a vacuum, has a level of conductivity - for electricity, for heat, for sound (all three are forms of energy), etc. The more dense something is, the better it is able to conduct. Air (particularly warm, dry air) is a very poor conductor because the molecules are far apart. The further apart the molecules of something are, the less influence they have on one another when they start moving (the actual term is "become excited".
Really, it's that simple - air is a a good insulator because the molecules are too far apart for it to be a good conductor.
Why Is It That People Wore More Clothing In The Past, Before Air Conditioning Was Invented ... ?
But Now We Have Air Conditioning And People Wear Hardly Anything In The Summer?
Because religious and societal norms set the standard on how people dressed. It was expected that an individual dressed in what was considered a dignified and decent manner. This meant that very little skin was revealed.
