Common Air Conditioner Problems and How to Fix Them

No one wants to be caught in the sweltering heat with a broken air conditioner. Whether it’s running non-stop, blowing hot air, or refusing to turn on, AC problems can quickly turn a comfortable home into a sticky situation.

At One Hour Heating & Air Conditioning, we believe in more than just quick fixes—we restore your home’s comfort with fast, reliable service backed by a 100% satisfaction guarantee. As a locally owned and family-operated franchise, we pride ourselves on personalized service, no extra fees after hours, and transparent pricing.

Below are the 10 most common AC problems and how you can address them with the help of our expert team.

1. AC Running Constantly

It’s normal for an AC to work harder in hot weather, but if it’s running constantly without shutting off, it could be an issue that needs attention.

Cause: Dirty air filters, thermostat issues, or electrical problems.

Solution: Check your thermostat settings or change the air filters. If that doesn’t help, contact us for a professional inspection. Book today for one of our expert technicians.

2. AC Not Turning On

Nothing’s more frustrating than an AC that won’t start, especially on a hot day. This is a common issue, but often it’s an easy fix.

Cause: Tripped circuit breakers or faulty wiring.

Solution: Check your circuit breaker first. If that doesn’t solve the problem, it’s best to leave electrical repairs to our certified technicians, who offer service after hours at no extra cost.

3. No Cool Air Flowing

If your AC is running, but no air is coming out, or the air isn’t cool, various issues could be causing it.

Cause: Faulty blower motor, low refrigerant, or dirty air filters.

Solution: Regular system maintenance can prevent these air conditioner issues. We offer free, no-obligation quotes for system replacements and repairs to get your home cool again.

4. Hot Air Blowing Out

Your AC should be blowing cool air, not hot. If it’s doing the opposite, it’s a sign something is wrong.

Cause: Dirty filters, blocked ducts, or a malfunctioning compressor.

Solution: Replace your air filters regularly. If that doesn’t work, schedule an appointment with our experts for a more in-depth assessment.

5. Refrigerant or Water Leaking

Leaks in your AC system can be serious, whether refrigerant or water. These leaks not only reduce efficiency but can also cause damage to your unit.

Cause: Degraded connections or blocked drainage pipes.

Solution: Turn off the AC and contact us immediately for a professional repair. We’ll send a technician to evaluate the situation.

6. Unit Turning On and Off Repeatedly (Short Cycling)

This problem, known as short cycling, can significantly damage your AC system if left unresolved.

Cause: Clogged air filters, miscalibrated thermostats, or an overpowered AC unit.

Solution: Start by changing your air filter. If the problem persists, our experts can assess your home’s cooling needs and recommend the appropriate system.

7. AC System Freezing

If you notice ice on your AC coil or copper lines, your system might be overworking to keep your home cool.

Cause: Dirty air filters, low refrigerant, or faulty blower motor.

Solution: Let one of our HVAC professionals check for obstructions or low refrigerant levels. Book a free appointment to get a quick diagnosis.

8. Air Conditioner Tripping Circuit Breaker Repeatedly

If your AC keeps tripping the circuit breaker, it could indicate poor installation or an electrical issue.

Cause: An AC unit that’s too powerful for your electrical system or faulty wiring.

Solution: Our HVAC experts can conduct a full electrical inspection and solve the problem, ensuring your system runs smoothly without overloading your circuits.

9. Strange Smells Coming from the System

Burning or musty smells from your AC can be concerning. These odors can signal underlying air conditioner issues that need immediate attention.

Cause: Electrical wiring issues, dirty air filters, or bio-growth in the ducts.

Solution: Replace your air filters and check for visible signs of bio-growth. If the smell persists, contact us for a professional system cleaning. We offer routine maintenance to help keep your system running fresh.

10. Sudden Weird Noises

Hearing squealing, grinding, or other unusual noises from your AC? These sounds often indicate worn-out components that require immediate repair.

Cause: Faulty motors.

Solution: Our regular maintenance service includes checking motors for proper operation to prevent noise and ensure smooth operation. Don’t ignore these signs—schedule an appointment today.
