If you own a home in the Central Valley, CA, you already know how important AC is to your comfort. With up to six months of each year with average highs between 78ºF and 95ºF, air conditioning provides an essential break from the heat. It makes sense to keep your existing system running for as long as possible, but inevitably, you’ll need to invest in a new AC eventually. Here are seven signs your air conditioner needs to be replaced.
Key Takeaways
- Air conditioners have a typical lifespan of 12 to 15 years.
- Older systems are more likely to break down, become inefficient, or use outdated refrigerant.
- Outdated systems will struggle to cool your home and may cause excessive humidity.
- Loves Air offers flexible financing and is available for quick, reliable AC replacement throughout the Central Valley, CA.
1. Your System Uses R-22 Refrigerant (or R-410A Is Leaking)
One of the most common signs you need a new AC system is an issue with the refrigerant. If your AC uses an outdated R-22 refrigerant, it makes sense to buy a new system.
If your system uses R-22 refrigerant, replacement is often the most economical long-term solution because R-22 is no longer produced. If your R-410A system develops a refrigerant leak, we’ll determine whether repairing the leak or replacing the system makes the most financial sense based on its age, condition, and repair cost. Refrigerants are hazardous to handle without the right protective equipment, and even a small leak can put you at risk, all while reducing the efficiency of your AC. To avoid rising repair and maintenance costs for your R-22 or R410A AC systems, a timely replacement makes sense.
2. Your System Is 12–15+ Years Old
If your home’s AC is nearing the 12-15-year mark, it’s likely time to consider replacing it. On average, you can expect a well-maintained AC to give you up to 15 years of service. If yours has reached 12 years or beyond, you’ve already gotten your money’s worth.
If you keep your system beyond the average AC lifespan, the odds of it needing expensive repairs will only increase, or you might experience a system breakdown at an inopportune time. To avoid this, it’s better to plan for a replacement at a convenient time.
3. You Need Frequent AC Repairs
Over their lifetime, it isn’t uncommon for even the best AC system to need a repair or two. Few parts of California put more stress on an air conditioner than the Central Valley. Long stretches of triple-digit temperatures force systems to run for hours at a time, accelerating wear on major components. If your AC begins needing unusually frequent repairs, it’s likely time for a replacement. Most ACs need frequent repairs when they’re in the final two years of their useful lives. So, if your AC needs more than one significant repair within a calendar year, take it as your sign to invest in a new, reliable AC replacement.
4. Your PG&E Bills Are Creeping Up
Another sign that you’re due for a new AC is seeing a steady increase in your Pacific Gas & Electric (PG&E) bills despite no change in your AC usage. If your existing AC is costing you a small fortune to operate, a replacement may be a good idea.
Today, even a minimally efficient new AC system will have a SEER rating of 15 or higher. If your AC is nearing 15 years old, it may have a SEER rating as low as 13. After years of wear and tear, it’s probably even less efficient than that. For the average 3-ton AC system, even a boost from 13 to 15 SEER would represent up to a 21% efficiency improvement.
5. Your Home Never Gets Truly Cool on Hot Days
If your existing AC simply isn’t making your home comfortable anymore, it’s likely time to invest in a new unit. You might also notice that your second floor stays much warmer than downstairs, no matter how long you run the system. This is a sign to consider investing in an HVAC system designed for a two-story home.
6. Unusual Noises, Odors, or Ice on the Lines
If you’re noticing loud screeching or banging noises, unpleasant musty or smoky odors, or spotting ice on the lines connected to your unit, it’s a sign of a problem. While these issues can be repaired earlier in the system’s lifespan, noticing multiple issues or spotting these problems towards the end of the system’s useful life is a sign that the unit is on its way out.
7. Your System Struggles with Humidity
Another sign that your AC is reaching the end of its life is excessive indoor humidity while running the system. This is often caused by restricted airflow or mechanical issues, and like the other problems on this list, it’s generally only worth repairing on relatively new units. If your older air conditioner seems to be acting like a humidifier, it’s probably time to invest in a new unit.
