What Is The Best Central Air Conditioner To Buy?

The professional who will be responsible for installing your air conditioner is the most important factor when considering a new air conditioner. It is more important than the brand you buy because no matter expensive the air conditioner is or how high tech it is. If the air conditioning system is installed poorly, it will not work, and all that technology and money will be wasted.

Factors that you should consider when deciding to invest in a new air conditioner involves

  • The environment
  • Size of the home
  • Size of the air conditioner
  • Expected usage

These factors when all considered will help you make the smartest choice in regards to operational and pricing efficiency.

What is a SEER Rating?

  • SEER – Seasonal Energy Efficiency Ratio = Air conditioners efficiency, the higher the seer, the more efficient the unit is. The federal government does not allow the sale of any new air conditioner with a below 13 SEER Rating. High seer rating a/c can save you thousands of dollars over the lifespan of the unit (10-15 years). The higher the SEER rating also equates to lower greenhouse gas emissions.

How Much Does It Cost to Replace and Install A New Air Conditioner?

Adding a new central air conditioning system to your home with an existing forced-air heating system in a 2,000-square-foot house, for example, would average from $3,000 – $4,000. If ducts need to be added, the cost can double. As opposed to window units, a ductless system is quieter, and can also heat your home.
