There are several signs that it might be time to replace your air conditioning unit. First, if your AC is more than 10-15 years old, it's likely less efficient and may struggle to keep up with your cooling needs. Another clear indicator is frequent breakdowns or the need for expensive repairs—if you find yourself calling for service regularly, replacement could be more cost-effective. Additionally, if your energy bills have been rising despite regular maintenance, your unit may no longer be operating efficiently. Uneven cooling in different rooms, strange noises, or foul odors coming from the unit are also signs of potential problems. Finally, if your AC uses R-22 refrigerant, which is being phased out, it might be a good idea to upgrade to a newer, more eco-friendly model. Replacing your air conditioner before it completely fails can help prevent uncomfortable temperatures and unexpected repair costs.
