For areas with long winters and short summers, central air conditioning might seem unnecessary.
Homeowners might prefer the lower cost option of window air conditioners.
These units are compact, lightweight and easy to install into the window. However, this type of equipment only provides cooling to a single room. It needs to be installed in the spring, removed in the fall and stored somewhere throughout the winter. Having open windows presents a security risk and invites bugs, pollen, exhaust fumes and all sorts of contaminants into the home. Exterior noise pollution such as traffic, early morning birds, neighbors and barking dogs can prove disruptive. Central air conditioning provides a rewarding alternative. Upgrading to a whole-home system is often an affordable investment. Because of the forced air furnace, quite a few of the essential components, such as the ductwork and vents, are already in place. Modern air conditioners feature variable-speed compressors that achieve SEER ratings up to 26. The ability to cater output to the exact requirements of the home makes them very energy efficient. The system is able to run longer at lower speeds, not only drawing less electricity but maintaining a more consistent temperature. The extended run times help to combat excess humidity and filter contaminants out of the air. The house feels more comfortable and stays cleaner and healthier. Central air conditioning is helpful for anyone who suffers from allergies, asthma or respiratory issues. A cool hygienic living space helps occupants to sleep better at night and be more productive during the day. Even when the weather is mild, running the cooling system on the fan-only setting circulates the air for a more enjoyable living environment.
