A good air conditioner can last up to 15 years or more, but even the best system will need a replacement eventually. You might also choose to upgrade your AC system for better comfort or enhanced energy efficiency. If you’re buying a new air conditioning unit for your Summerville, South Carolina, home, make sure you consider these key points.

Size

Size is one of the most important factors to consider when you’re purchasing a new air conditioning unit. If the system is too large, it will use more energy than necessary cycling on and off frequently. If the system is too small, it may run continuously yet never reach your home’s programmed temperatures. The appropriate size for your air conditioner is based on your home’s size, location, insulation and other factors. A technician can inspect your home and help you determine the appropriate tonnage for your new AC system.

Efficiency Ratings

Air conditioners receive seasonal energy efficiency ratio (SEER) ratings that indicate how efficient they are at cooling homes. The higher your system’s SEER rating, the more efficient your system will be. New AC systems must have a SEER no lower than 13, but extremely efficient options may have SEER ratings that are over 20.

Compressor Speeds

Your air conditioner may have a single-speed, two-speed, or variable-speed compressor. A single-speed compressor is either on or off, always running at full capacity. A two-speed air conditioner gives you greater control over temperature adjustments and energy use because it can run at either high speed or low speed. A variable-speed compressor is the best option, as it allows for small adjustments to speed that allow you to get the ideal temperature with minimal energy use.
