What are the Signs I Need a New AC Unit?

Summer Walk

An air conditioner is crucial for comfort in your daily life, especially here in Tennessee, we get hot and humid often long before some of our northern neighbors. A well maintained AC unit, (yearly inspections and monthly filter changes) can last 10-15 years.

How do I know if I need repairs for my unit or if I need a replacement?


How old is your air conditioner? The most common reason for a new unit is age. The older your unit gets the less efficient it is and it will continue to lose energy efficiency over time.

Pay attention to how often it needs repairs. Once a year isn’t quite indicative of the need for a new unit yet, but it certainly means you could be getting close to the time to replace it. Getting a new unit can actually save you money in the long run on energy costs and repairs.

Replacing an old unit can also have unseen benefits, including improved air quality and reduced carbon emissions.

Temperature Inconsistencies

Another thing to look out for is how consistent the temperatures in your home are. Unstable temperatures aren’t always directly related to needing a new AC unit, but combine this with the age of your unit and you could be looking for a new one soon.

Temperature inconsistencies also can be the result of leaky ductwork or poor insulation. So contact someone in our office today and we can have one of our service technicians diagnose the problem for you.


When a unit gets older it performs less efficiently. One thing to pay attention to is the humidity level in your home. As a unit ages it becomes less efficient at removing humidity.
