What Really Matters When Choosing An AC Unit?

Posted on: 23 March 2022

Buying a new air conditioning system is a substantial investment in your home's future. These units can last for many years, so your choice is likely to be with you for some time. Even if you don't plan to live in your home for the system's lifetime, your choices can affect your home's value and the impression it gives to potential buyers. 

However, making the right decisions may seem overwhelming, especially with so many options. This guide will give you the two important factors you'll need to consider for your new system and one that's surprisingly not something to worry about.

1. Consider: Efficiency

Air conditioning manufacturers rate their central AC systems using a value called SEER, or seasonal energy efficiency ratio. Does this sound complex? Don't worry! You don't need to know the details of SEER or how manufacturers calculate it. Instead, remember that SEER ratings provide direct, linear comparisons. In other words, you get 50% more efficiency from SEER 15 vs. SEER 10.

However, your real-world efficiency will depend on more than just your AC unit. Your ductwork can potentially reduce the efficiency of your system, as can poor insulation, drafty windows, and numerous other factors. Still, you can use SEER ratings to compare one air conditioner to another, even if your home may not allow them to reach their maximum theoretical efficiency.

2. Consider: Features

Modern AC systems come with some fancy bells and whistles that you may want to consider when buying a new system. For example, some high-end systems have variable compressors and multi-stage blowers. Instead of running at full speed all the time, these systems can vary their cooling power and airflow based on conditions in your house.

You can also find features that allow for quieter operation, better integration with smart home technology, and even more reliability. If you want the best of the best, it's worth considering units that go a step above the basics.

3. Don't Worry: Capacity

You might be surprised that you don't need to consider your AC unit's capacity. Like other HVAC equipment, your air conditioner needs to be the correct size for your cooling load. An AC unit that's too large or too small will have trouble cooling your home efficiently. Poorly sized units may even wear out more quickly and require more repairs and maintenance.

When you install a new system, your HVAC technician will perform a cooling load calculation and let you know the capacity you need. Aside from following this recommendation, you shouldn't need to worry about the cooling capacity of your new system.
