If you know that you need to purchase a new central air conditioner this year, now is the time to shop for the right model and have your new unit installed. This way, you'll be prepared once the temperatures start to rise in the spring.

The following are six mistakes you need to avoid if you need to buy a new air conditioner to maximize the efficiency and effectiveness of your new unit:

Automatically buying the same size unit

You should reevaluate before you purchase a new air conditioning unit. You might want to get a unit that is sized differently than your previous unit was. 

Discuss air conditioner size with your HVAC technician. Your technician might suggest that you get a smaller unit if your utility bills were unusually high in the hot months or a larger unit if it was hard to keep your interiors cool enough with your old unit.

Also, you will need to get a larger unit if you've put additions on your home that have increased the amount of interior space you're cooling.

Being unaware of what SEER values are

It's important to get an efficient unit to minimize your home's energy consumption. It's good to look for a unit with a higher SEER rating if you want to maximize efficiency and save money every month on your utility bills.

The SEER rating on air conditioner models is a measurement of how efficiently the unit operates. The higher the SEER rating, the more efficient the air conditioner is. 

Choosing an air conditioner with a single-stage compressor

The compressor of an air conditioner is one of the most important components. Air conditioner compressors are either single-stage or two-stage compressors.

Generally, two-stage compressors operate more efficiently than single-stage compressors. This is because two-stage compressors have two different speeds that they run on so that their operation can match cooling needs more exactly.

Choosing a unit that doesn't allow for easy access to the inside coil

One important maintenance task when it comes to keeping an air conditioner in good shape is cleaning the inside coil. If you want to speed up maintenance procedures, choose an air conditioner unit that offers easy access to the inside coil. 

Ignoring warranty considerations

You should be aware of how long your air conditioner warranty will last before you purchase a new model. You should look out for an air conditioner that offers a warranty that will last at least 10 years for all mechanical components. 

Buying a new unit after temperatures heat up

Now is the time to purchase your new air conditioner. When it starts to get warm outside, AC unit prices will go up and AC technicians will become busier so that it will be more difficult to schedule your installation.
