When a heat wave hits, you don’t want to be without the best central air-conditioning unit available. Sifting through the various options and brands can quickly become overwhelming. To help you narrow your search, this guide will give a brief overview of a few of the most important qualities you need to consider when purchasing a new central air-conditioning unit.

Qualities to Consider

  • Power levels

Every air conditioner has a specific power output level that needs to be tailored to fit the parameters of your home. An underpowered unit will just run and run all day without ever getting your home cool and waste a huge amount of energy in the process. An overpowered systems can be just as wasteful. Air conditioners use much more energy starting up and shutting down than they do when running. For this reason, they should run for at least 15 minutes at a time in order to make the best use of consumed energy.

An overpowered unit will “Short-cycle”. Short-cycling is when an AC unit cools the home too quickly and shuts down, only to turn on again a few minutes later as the house warms up. Short-cycling can increase wear and tear on the system and raise energy costs. An ideal air conditioner matches the specifics of your home perfectly and is neither overpowered, nor underpowered.

  • Efficiency ratings

Once you know the power load of your air conditioner, you’ll need to determine which system in your price range makes the most effective use of its energy. The SEER rating, which stands for Seasonal Energy Efficiency Ratio, gives you a quick-glance look at the system’s effectiveness. The higher the rating, the better job it does at cooling your home.

The minimum standard SEER is 13 for air conditioners. Most modern air conditioners have a SEER that ranges from 13 to 21. It’s important to remember the efficiency of your system can also depend on the size of your home, your current ductwork, and other variables.

  • Warranty

Every air conditioner comes with a warranty covering the parts involved in case they break down during a certain period of time. The longer the warranty, the greater period of time for which you’re covered in the event repairs are needed down the road. Various brands and HVAC companies will provide different options for extended warranties that can save you repair costs during the system’s extended lifespan.
