Central AC Unit Maintenance

Why should keep your central AC maintained?

Central air conditioners provide circulation of cooled air through supply system and return ducts. The process merely works, so supply ducts and registers (such as openings in the floors, walls, or ceilings) convey cooled air from central air conditioner to the home. While circulating through the house, this cooled air is getting warmer and flows back to the central air conditioner through return ducts and registers. Keeping your central air conditioner unit maintenance under control regularly generates several benefits such as saving money on energy, extending the lifespan of central air conditioner unit and exclusion from additional expense for early replacement.

The evaporator is placed indoor cabinet where a furnace and internal part of a heat pump are attached. Evaporator coil of the air conditioner is installed in the cabinet or main supply duct of that furnace. A split-system is the most economical central air conditioner unit to install if there is a furnace but no air conditioner at your home.
  2. In a packaged central air conditioner has one cabinet which contains the evaporator, condenser, and compressor altogether. The cabinet is mainly placed on a roof or on a concrete slab next to the house’s foundation. This type of air conditioner often is provided by electric heating coils or a natural gas furnace. So, you don’t need a separate furnace indoors because of the combination of an air conditioner and central heater.
