Signs It’s Time to Install a New Air Conditioner
Knowing when to replace your air conditioner can save you time, money, and unnecessary stress. Over time, even the most reliable systems lose efficiency or begin to break down more frequently. Identifying the right time to spring for a replacement unit instead of an AC repair service can help you avoid unexpected repairs and maintain a comfortable home environment—including helping you save money by avoiding higher energy bills during peak summer months.
Some common signs that it may be time to replace your air conditioner include:
- Your AC is over 10–15 years old and no longer performs efficiently.
- Frequent breakdowns or repairs are becoming costly and inconvenient.
- Your cooling costs have steadily increased, even with regular maintenance.
- It struggles to keep your home at a comfortable and consistent temperature.
- You notice unusual noises, odors, or excessive humidity while it’s running.
- The system uses outdated refrigerant, such as R-22, which is no longer environmentally friendly or cost-effective.

At 1st Choice Mechanical, we’re proud to be a truly family-owned and operated business. We believe in doing things the right way with certified technicians, honest advice, and customer service that feels personal. Whether you’ve worked with us before or you’re just getting to know us, we’d love to share our story.
