Tips To Extend The Life Of Your Central Air Conditioning Unit

Posted on: 9 September 2022


Central air conditioning is right up there with indoor plumbing and Wi-fi when talking about technologies that have made life at home easier and more comfortable. Most people cannot imagine having to sit in an overly hot house for 3 months out of the year.  Proper care of your AC unit is important to extend its life. Without it, the unit probably will not last the 10 -15 years most professionals expect them to last. Here are a few tips to ensure your unit lasts at least at the upper end of this and possibly even a few extra years.

Smart Thermostat  

Technology has advanced to the point of thermometers that can be programmed to adjust air conditioning units to turn the temperature up and down according to who is home and the time of day. There is no sense in keeping the house at a lower temperature when no one is there, however, you don't want to walk into a hothouse and have to wait for it to be cooler. a smart thermometer can turn the temperature up before everyone leaves so it will still be cool while you are there but then start to heat up once everyone is gone. It can then turn down the temperature before everyone returns so it is comfortable as soon as you walk through the door,

Filters and Ducts

Regardless of how clean your home is, there is going to be dust and bits of dirt and debris that get caught in the return air vent for the AC. As this all builds up the system will have to work harder to maintain the proper temperature. The filters in these vents need to be replaced often to allow for the air to flow properly. It is also important to have the ducts cleaned out regularly. While the filters keep a lot of particles from entering, they can't keep out everything.


Having your AC system serviced annually is important to its efficiency and to its life expectancy. The technician can often find small issues that would grow into major problems while performing routine maintenance. In addition to saving the system, this will save you more money than what you spent on the service call. 

Eventually, an AC unit is going to need to be replaced. However, proper care will give you extra time to decide which unit you will purchase next.
