Summertime can be beautiful and relaxing or you could be sitting in front of a box fan wishing you had air conditioning or wishing it would snow. Maybe you’re stuck in one room of the house because your air conditioning unit will only cool one area. Consider upgrading to a central air conditioning system for whole house cooling without damaging ledges or adding an unsightly box to your window.
A central air conditioning system is considered the most quiet way to cool your home, with the added convenience of all rooms being cooled by one unit. By using a programmable thermostat system, you can also save money on cooling costs.
Your system may be set up as an HVAC system known as a heat pump that handles both heating and cooling functions. This type of system works well in climates that do not have extreme heat or cold. According to consumerenergycenter.org, a heat pump can save you 30 to 40 percent on the amount of electricity needed to cool or heat a home with separate air conditioning and heating units.
Central air conditioning units deliver cold air through the same ducts that your furnace or heat source uses. In a split system, there is one cooling unit outside (the condenser) and one inside the home (the evaporator coil) that services the entire home as opposed to several air conditioning units that must be placed in the windows throughout your home. Packaged systems have both the condenser and the evaporator combined into one unit that sits outside the home.
The outdoor unit moves the refrigerant through copper tubing to the evaporator coil which is attached to furnace inside the home. The refrigerant cools and becomes a low pressure gas. This gas absorbs the heat from your ductwork and returns to the outdoor condenser where it is again turned into a high temperature, high-pressure gas and recycled through the system, back to the evaporator coil.
Central air conditioning systems also act as dehumidifiers. The moisture in the warm air passing over the evaporator coil condenses and is drained away. This may eliminate the need for dehumidifiers in the basement of your home, saving additional energy costs.
Consider the bel sound rating, zero to thirteen, with zero being no sound to thirteen being a painful level of sound, when shopping for a central air conditioning system.
