There is a major misconception when it comes to choosing an a/c unit… size does not matter. When you are in the process of choosing your Heating and Air Conditioning system, you must typically take the size of the building into consideration. If you don’t, this could have you in some serious issues really fast. Reason being, when you don’t take the size of the building or home you will be cooling into consideration, your modern Heating and Air Conditioning device may not be strong enough and will break down quick. For example, say you buy an a/c device big enough to remain comfortable at 75°F inside when it’s 99°F outside. If it gets any hotter than that, your Heating and Air Conditioning system will not be able to keep up with it! It will not matter how low you set the cooling control unit thermostat. Then you realize it’s running always, trying to keep up with cooling your house. I can’t imagine what your electric bill may turn out to be. This turns into lots of dough out of your pocket. You then suppose instantly something is wrong. So you call your local Heating and Air Conditioning or a/c service serviceman who then comes out on a service call, which is again, more dough out of your pocket. Then they turn to you and say that your device is too small to fully cool down your home. So that means again, your cooling system, no matter how low you turn down your control unit’s thermostat, will not be able to cool your nice house the way it should. Make sure when you go to purchase your next a/c unit, you make note of how big of a device you need. This is very important!
