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.
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
To estimate the cost of installing central air conditioning, determine the BTUs needed for the area first. Consult the Energy Star website to find BTUs needed for different square footage measurements. Costs vary based on this information, as well as any needed duct work.
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.
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
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.
The cost to install an air conditioning unit varies widely depending on the weight of the unit and several other variables. You can expect to spend anywhere from $3,000 to $12,000.
Low-income households may qualify for subsidies to cover the cost of air conditioning through the LIHEAP program. These programs are administered by local governments and do not always provide funds for purchasing new air conditioners, but local charity programs sometimes make these available to vul
A high-velocity central air-conditioning system is an air-cooling system that operates through small, flexible tubes that are inserted into and wrapped around and above closets, crawlspaces and ceilings. It is typically installed in buildings with no air ducts.
Air conditioners work by transferring heat energy from inside the home to the exterior. Liquid refrigerant absorbs heat from the home, becomes a gas, and travels to the outside. A compressor and condenser then converts it back to a liquid, and it releases the energy, thus beginning the cycle again.
