Basics of air conditioning
AC units can be compared on a multitude of dimensions. Certainly efficiency is one of the main drivers, and given what’s happened lately with the cost of gas and electricity, efficiency has become extremely important.
In general, there are three factors to be aware of when selecting an air conditioning system:
1. Efficiency — Buy the most efficient air conditioning unit available, especially in the desert Southwest. Efficiency refers to how much energy the system will require to do its job. HVAC specialists use what are called “S.E.E.R” numbers to rate and compare different cooling systems. SEER stands for Seasonal Energy Efficiency Rating. This is a standardized test, and the higher the SEER number, the more efficient the air conditioning unit is. Now the minimum efficiency, the builder’s model, is rated a 10 and they go all the way up to 18. So make sure the air conditioning unit has a rating of 10 or higher.
2. Regional Climate — When designing a home, it’s important to know the external factors that will need to be solved. In the desert southwest, it’s one of high summer heat. In the northwest, it may be one of damp, cold winter weather. In the northeast, it’s most likely frost in the winter and high humidity in the summer.
3. Noise — Internal sound is just as important as the sound coming externally from an air conditioning unit that’s installed outside the kitchen or living room window. Be sure to purchase a unit that’s as quiet as possible.
