When you live in Arizona, a working air conditioner isn’t just a comfort—it’s survival. But most homeowners don’t realize their system is on the brink until it completely stops. Catching the signs early can save you money, stress, and a whole lot of sweat.
Here are five warning signs your AC system might be on its way out—and what you should do about it.
If your vents are blowing weak or warm air—even with the thermostat set correctly—it could be a sign of low refrigerant, compressor issues, or duct leaks. In Arizona’s triple-digit heat, this is a red flag you can’t ignore.
Pro Tip: Check your air filter first. If it’s clean, it’s time to call a technician.
Grinding, rattling, or banging sounds are never normal. These can indicate loose components, motor issues, or broken fans. The longer it runs like this, the more damage it causes.
What to Do: Shut it off and call for an inspection before it turns into a full system failure.
If your power bill spikes but your usage hasn’t changed, your AC is likely working too hard to keep up. This could mean your system is aging, dirty, or in need of serious repairs.
Solution: Schedule a diagnostic tune-up to identify inefficiencies and catch small issues before they snowball.
Your AC should cycle on and off at steady intervals. If it’s starting and stopping frequently, it may be an issue with your thermostat, electrical components, or improper sizing.
Why It Matters: Short cycling wears down your system faster and drives up your energy costs.
Leaks around your air handler or puddles near your condenser aren’t just messy—they could signal refrigerant leaks or clogged drain lines. Both are serious problems that need attention ASAP.
Pro Tip: Never attempt to handle refrigerant yourself—leave it to the pros.
