For the readers who just want to buy a new central for your brand new house, you can skip this part and go straight to the NEXT PART:  Basic AC Parameters Need to Know

There are many reasons why you might want to replace your existing system. The most common is an aged and inefficient AC system. When you are replacing or upgrading your central AC, do not automatically go for the same one you had before. There are new models that save more energy, function better and last longer.

Secondly, consider whether you need to replace the whole system or only certain parts. Generally, it is recommended that you replace the whole system to ensure that energy efficiency is as high as possible. One faulty or incompatible part can cause energy losses. If you want to retain any existing part such as the furnace, have a professional evaluate it and decide whether it can still be used.

Other important replacement tips include:

  • Do not automatically go for the same size you had before. You may need less cooling due to changes you have made such as insulation and installing energy saving windows. Your cooling needs may also have increased perhaps due to more rooms being added.
  • If you are short on budget, you do not have to buy a super high-efficiency AC such as those with a SEER rating of 23. With a major improvement in technology in recent years, you can now buy a lower efficiency AC (around SEER 14-17) and still save a lot of energy.
  •  Do not hire a contractor until he has carried out a comprehensive survey of your current AC. Most HVAC companies offer free surveys and quotes. Get at least three quotes before making a final decision.
  •  Get a programmable thermostat with your new AC. This type of thermostat automatically balances heating and cooling depending on current needs. For example, when no one is home, it dials back energy usage. A programmable thermostat is highly effective at saving energy.
  • Expect to pay more for a good system. It’s better to pay more for a good AC that will save you much more energy than a cheap inefficient one. It is an investment that will pay for itself over time as you pay less to your utility provider.
