How to Identify When You Need AC Replacement

Too often a failing air conditioner catches homeowners off guard. The air conditioner is the most expensive appliance in the home and it's the least planned for. The last thing you want to do is suffer the summer heat without a cooling unit. By being observant and listening to your AC (sometimes literally), you can have a warning when it’s time to replace your air conditioner.

It’s time to install a new AC if you notice the following:


  • Frequent repairs – Do you constantly find yourself having to fix your AC? All those repairs might indicate a failing unit. It’s better to invest in a new AC than to continually throw money at a dying unit.
  • Age – The average air conditioner lasts for about 12 to 15 years. If properly maintained, it might last for a few more years. But if it’s older than 15 years, it might be time to replace.
  • Higher electric bills – When an AC is failing, it will work harder to output the same results, thus using more energy. If you notice higher energy bills without changing your routine, it can indicate a serious issue with your system.
  • Decreased cooling – Is your AC unable to produce cold air like it used to? There could be an issue with the thermostat or refrigerant.
  • Strange noises – Do you hear strange rattling or screeching noises coming from your AC? There could be something wrong with motor, belt, or a loose part. This can all be cause to install a new air conditioner.

Working as a team, our Chattanooga AC service technicians and installation professionals can evaluate your existing system, and provide a cost-benefit analysis that will help you create a plan for replacing your air conditioner. One thing is certain: It's much better to schedule your air conditioning replacement rather than have your unit suddenly stop working and discover it is beyond repair.
