In San Bernardino, a reliable AC isn’t a luxury—it’s a necessity. But like all hardworking machines, air conditioners don’t last forever. While some issues can be solved with a repair, there comes a point when it makes more sense—financially and comfort-wise—to replace your unit entirely.

At AC Volt Heating & Cooling, we know how important it is to keep your home cool without constant breakdowns or energy waste. If your system’s been acting up, here are the top signs it might be time for a replacement.

1. Your System Is Over 10–15 Years Old

Most AC units are built to last around 10 to 15 years with proper maintenance. If yours is in that range or older, you’re likely missing out on today’s energy-efficient technology—and could be heading toward more frequent issues. At AC Volt Heating & Cooling, we can help you determine whether your system is still holding strong or hanging on by a thread.

2. Frequent Repairs Are Draining Your Wallet

If you find yourself calling for repairs every season—or even more than once a year—it’s time to add up those costs. Investing in a new unit can actually save you money in the long run and give you peace of mind during peak Inland Empire heatwaves.

3. Your Energy Bills Keep Climbing

Older or malfunctioning units tend to work harder to produce the same results, causing your energy bills to rise. A modern, properly sized AC system installed by our trained techs can help cut those costs significantly.

4. Uneven Cooling or Poor Airflow

Are some rooms always warmer than others? Do you feel like air is barely coming out of the vents? These can be signs your AC is struggling. A replacement can improve airflow, humidity control, and overall indoor comfort.

5. Strange Noises or Odors

Rattling, banging, or screeching sounds—and persistent musty smells—are all red flags. These often signal failing components or mold growth in the system. Don’t ignore them.

6. It Still Uses R-22 Refrigerant

If your unit was installed before 2010, it might still use R-22 refrigerant, which is now phased out due to environmental concerns. Replacing the system is not only better for the planet—it also saves you the headache of costly refrigerant refills.
