Find Out Which 5 Air Conditioner Problems Strike Most Often

Warning signs your air conditioner will breakdown

Let’s be honest—it’s impossible to avoid air conditioner problems. But it’s still helpful to know what the most common A/C breakdowns and warning signs are. That’s why we’re sharing the top five issues we see and what our recommended fixes are.

Broken Thermostats

We know this seems too easy to be true but something as simple as dead thermostat batteries can cause your air conditioner problems. That’s why we recommend homeowners check their thermostat first when things go south. If your thermostat screen goes dark or your A/C won’t turn on or off, simply replace the batteries to see if it starts working again. If not, call for backup from your local cooling pro, Roth Heating.

Clogged Air Filter

Warning signs your air conditioner will breakdownDirty air filters are another leading cause of air conditioner breakdowns. They block airflow, overload the motor, and often cause complete failures. Not sure if your filter needs to be changed? Pay attention to airflow when your fan is running. If it feels weaker than usual or your home isn’t cooling off, it probably needs replacement. Another way to tell is by holding the filter up to a light source and seeing if any light comes through. If not, either replace or clean it (depending on filter type) to get air moving again.

Circuit Breaker Problems

Circuit breakers trip and shut A/Cs down for several reasons:

  • Short-circuiting—two hot wires, or a hot wire and neutral wire, touch and send excess amperage to the circuit, tripping the breaker.
  • Ground fault—essentially a form of short-circuiting when a hot wire hits a ground wire.
  • Energy pulling—systems malfunction and pull too much energy, tripping your breaker.
  • Circuit overload—devices tied to the circuit demand more amperage than the circuit can supply.

Keep an eye out for inconsistent system operation or frequently tripped breakers. This indicates your system isn’t operating correctly and needs service ASAP. We may need to simply clean your unit, swap out a dirty air filter, or replace a failing motor.

Blown Capacitors

Capacitors are the small cylindrical components that store energy. Without these jolts of electricity, your motor, compressor, and fan will stop running. These signs will tell you your capacitor is on its way out:

  • Humming noises
  • A/C turns off on its own
  • A/C won’t turn on
  • Rising energy bills

If you notice these signs, turn your system off right away and call for an emergency repair. We’ll inspect your capacitor, find the cause of the problem, and then replace it to keep your system going.

Refrigerant Leaks

Refrigerant is the chemical that runs through your A/C to provide cool air. If your refrigerant line leaks, you’ll notice a loss of cooling power, hissing sounds coming from your system, frozen coils, and higher energy bills. It’s difficult to diagnose a leak on your own, but one call to a professional and you’ll know if you have a leak and what your best course of action is. Especially because the most common refrigerant (R-22) is being phased out and is becoming increasingly more expensive.

Maintenance Is Your #1 Defender Against Breakdowns

While these common problems are unavoidable, you can reduce their likelihood with routine maintenance. Just call or contact us online to schedule your tuneup—or request emergency repair service if your Carrier® or other brand A/C is already on its way out.
