How to Buy a New AC System.

Today’s high-efficiency air conditioners use about 30% to 50% less energy than those manufactured even just a decade or so ago.  In fact, your current system is about 10 years old, you can cut your annual AC-related energy costs, on average by 20% – 40%.  By any measure, that represents a substantial savings.

Still, the efficiency of the “box” itself is just part of the story.  For you to enjoy the maximum in long-term efficiency and energy savings, your system needs to be properly sized; as part of the determining the correct size of any home air conditioning system, several factors must first  be determined and calculations made by a qualified and licensed air conditioning contractor.

System Sizing

Buy a New AC System.Air conditioners are rated by the number of British Thermal Units (BTUs) of heat they’re able to remove from your home per hour. Another common rating term for air conditioning size is the “ton,” where one ton is equal to 12,000 BTUs per hour. The efficiency, performance, durability, and initial cost of an air conditioner are functions of matching its size to the following factors:

  • The size of your home and the number of windows it has.
  • The amount of shade that falls on your home’s windows, walls, and roof.
  • How well our ceilings and walls are insulated.
  • The amount of air that leaks into your home from outdoors.
  • How much heat is produced by home occupants and appliances.

Here’s something else to keep in mind:  when it comes to AC sizing, size IS everything.  That’s because a smaller-than-needed unit will have to work overtime to produce the desired amount of cool air. 

By the same token, an over-sized AC system brings with it these negative consequences:

  • Higher up-front cost.
  • Frequent on and off cycling which reduces its efficiency.
  • Frequent on and off cycling also creates temperature fluctuations which impair indoor comfort levels.
  • Greater system wear and tear which inevitably leads to more repair problems down the road and a shorter system lifespan.
  • Increased energy consumption.
