Central Air Conditioning

Despite the high initial cost, homeowners are drawn to central air conditioning systems because they can cool the entire home—not just one room. Central systems are also a great selling point for future homebuyers. If you think this air conditioning unit is right for your home, here is some more information to get started.


If your home already has the proper ductwork in place, you can expect to pay between $3,500 and $4,000 to install a central air conditioning system in a 2,000-square-foot house. However, without the proper ductwork, the cost can double to about $7,000-$8,000. Get in touch with a licensed HVAC contractor for more system and installation costs.


Central air conditioning systems are far less noisy than other units and systems.

Central air conditioning systems are able to cool the entire home, not just one room like other systems.

They can filter and dehumidify the air, making it the better choice for people with asthma or allergies.


Central air conditioning systems are the most expensive to install.

They also have a high up-front cost.

Central systems cannot be relocated like other air conditioning units.


While certainly more complicated to install, central air conditioning systems are expected to last at least slightly longer than a window air conditioning unit, with an average life expectancy of 15 years. This requires, of course, that you regularly clean and maintain the unit and its filters. Always call a professional at the first sign of a problem.


If a central air conditioning system fails to operate, chances are it hasn’t been maintained properly. To avoid costly repairs, it’s essential to clean and replace the filter regularly (at least once a month).

Also, vacuum out the interior of the unit to get rid of dust and debris, lubricate the bears on the fan motor and centrifugal fan unit, and regularly ensure that all electrical connections are working correctly. Lastly, clean the condenser coils by spraying them with a hose.
