Air Conditioning 101

Air conditioning is fairly simple when you get down to the basics. All air conditioners, whether they're small window units or central systems that cool an entire house, work on a similar cooling principle, much like your household refrigerator. And just like refrigerators, they come in different sizes, functionalities, and energy efficiencies. In order to ensure a long and healthy life for your air conditioning system, there are a few basic maintenance checks that should be performed—some by you and some best left for the pros.

Care and Maintenance

Dirty coils and improper refrigerant levels can cause your system to cool less efficiently than it should. An inefficient system means higher energy bills. Your compressor works harder than it should, and the life span of your unit is shortened.
With good maintenance, your air conditioner should last about 15 years. You can keep your system running efficiently with these easy tips:

  • Check all hose connections for leaks, and make sure the condensate tube is draining freely.
  • Change or clean the air filter once a month. This is especially important during the summer when dust and allergens are prevalent.
  • Keep plants and shrubbery at least 2 ft. away for adequate airflow around the entire unit.
  • Vacuum the air vents and registers, or grills, regularly, and consider a professional duct cleaning every few years.
  • Keep furniture and drapes away from registers.

There are other maintenance procedures that are best handled by a professional service provider. Consider having a professional inspection done once a year by an experienced technician to ensure that your system is running efficiently. Some technicians perform free inspections, while others charge a fee for service calls. Any repairs are likely to result in additional costs.
