Whenever you are considering buying a new AC unit for your home or replacing the existing central air, it is always best to work with an HVAC professional to make sure you get the right unit. Contrary to popular belief, not all AC units are created equal and a proactive homeowner takes the time to understand the important elements that set AC units apart.

Sizing The Unit

Each home requires a specific size air conditioner to get the maximum efficiency from the unit. If you buy a unit that is too small for your home, your energy bills will skyrocket and you will probably have to replace the unit sooner than expected. If your AC unit is too large, then you are wasting money on a machine you do not need.

The size of the AC unit also depends on how energy efficient your home is. If you have good windows and strong insulation in your roof, then you can spend less on a smaller unit and save money. If your home needs energy efficiency upgrades, then you will need to buy a unit that will cost a lot every month to run.

SEER Rating

The Seasonal Energy Efficiency Ratio (SEER) is a number that indicates the energy efficiency of your AC unit. It measures how much energy you would need to supply your AC unit to be able to cool your home to the temperature you desire, and the higher the SEER rating the better. In the United States, all AC units must have a SEER rating that is no lower than 13, but you can buy units with ratings as high as 25.5.

Obviously, an AC unit with a higher SEER rating is going to cost more money, but it will also save money over time. But that does not mean that you should automatically buy a unit with a 25.5 SEER rating. You should talk to an HVAC professional to decide what kind of SEER rating your AC unit should have.

The Right Compressor

Most AC units come with either single-stage or two-stage compressors. On an AC unit, the compressor is one of the most expensive and important parts of the unit. A single-stage compressor is constantly working at its highest energy output to create cold air. In some situations, these compressors are the right choice.

A two-stage compressor is able to move from high to low speeds and alternate energy usage as needed. While this sounds like the ideal solution for every AC unit, there are situations where a two-stage compressor is not the best choice. An experienced and certified HVAC professional can help you to make the right choice of compressors in your AC unit and get you the best value for your money.

Buying a central air conditioning unit takes some planning and strategy. You need to know exactly what you need, and then you need to be able to make the right decisions when it comes to equipment. With the help of an experienced HVAC professional, you can go through all of your options and make the choice that is right for your home.
