Many people use a contractor to install home central air systems, but it is possible to do much of the work yourself. Attempting to install central air systems is only recommended for construction-savvy individuals. Regardless of expertise, make sure to follow local building codes, instructs eHow.co
Some common problems with central air conditioners include faulty wiring, low Freon levels, failure of the outside fan or unit to work, and the coil freezing. Most of these problems can be avoided through preventative maintenance.
A central air conditioning system consists of two main components: an indoor air handler and an outdoor compressor. The air handler contains an evaporator coil and a fan to force air over the pipes, while the outdoor unit contains the compressor, a condenser coil and an exhaust fan.
Central air conditioners labeled with the ENERGY STAR logo meet energy efficiency guidelines set by the U.S. Environmental Protection Agency. This means that the air conditioner has a higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio ratings, making them over 15 percent more
Common approaches to starting repairing a central air conditioning unit are to check the circuit breaker, thermostat and the internal switch. Dirty air filters also impact the circulation and the velocity at which the system blows out air.
A central venous catheter, or a central line, is a thin and flexible tube that is inserted into a patient's arm or chest, according to WebMD. The tube then delivers medicine, fluids, blood products or nutrients to a patient for an extended period of time.
To purge a central air system of odors caused by mold or mildew, replace the filter, inspect and clean the top of the air conditioner, clean the condensate drain, and evaluate the results. This procedure takes several days and requires a new filter, a wrench, bleach and a scrub brush.
The benefits of a central air conditioner include noise control, filtered air, enhanced comfort and a covert appearance. Other benefits are less energy consumption, a consistent supply of comfortable temperatures and an increase in overall home value.
The U.S. Department of Energy recommends setting the central air thermostat to 78 degrees Fahrenheit during the summer months to conserve energy and reduce energy costs. When a home is unoccupied, raising the thermostat to a temperature of 82 F to 85 F can further reduce energy costs.
As of 2015, window air conditioners generally cost under $1,000, typically ranging between $200 and $500. By contrast, central air conditioner installation costs anywhere between $4,000 to over $10,000 depending on whether or not the home already has the proper setup.
