Common HVAC Issues Your AC Might Have
Before deciding between a DIY fix and calling a certified HVAC technician, it is essential to understand the potential AC issues you may be experiencing and what might have caused them. This helps you decide whether to resolve it yourself or call a professional.
1. Poor Airflow
Suppose your air conditioner is running, but the airflow feels weak or uneven throughout your home. In that case, it is a sign that something is blocking or limiting your system’s ability to circulate air efficiently. The common causes of poor airflow include:
- Clogged air filters: If your filter is clogged with dirt, debris, pollen, etc., your system will be unable to pass air through it, reducing cooling efficiency and airflow.
- Blocked or leaky ductwork: If you notice poor airflow in your home, check the ductwork for signs of tears or blockage. Air can escape through these tears, reducing the amount that gets into your home, while blockage also limits the air supply.
- Malfunctioning blower fan: A failing fan motor will not push enough air through your system.
Apart from reduced cooling and poor comfort, reduced airflow forces your system to work harder to meet your comfort demands. This increases energy consumption and utility bills. And if the problem is not promptly fixed, it can lead to a system breakdown and reduce the lifespan of your equipment.
2. Warm Air Instead of Cool Air
Your air conditioner should not be blowing warm air or room temperature air unless it has been set to do that. Here are some common causes of AC blowing warm air:
- Thermostat set to heat mode: Ensure the thermostat is set to the cool mode and the desired temperature is lower than the room temperature.
- Tripped circuit breaker: A tripped circuit breaker or faulty electrical wiring can affect the performance of your AC system.
- Low refrigerant levels: The refrigerant is essential to the cooling process. When your refrigerant is low, your AC will blow warm instead of cool air.
- Dirty evaporator coils: Your evaporator coil plays a key role in cooling the air in your space. If these coils become frozen or dirty, their efficiency will be reduced.
If your refrigerant levels are low, the evaporator coils are frozen, and your compressor has failed, contact a professional HVAC repair service for safe handling.
3. Short Cycling
Short cycling occurs when your AC turns on and off at short intervals, rather than running for longer, continuous cycles to effectively cool your space. The common causes of short cycling include:
- Oversized HVAC: An oversized system cools your home too quickly, leading to short cycles and inefficient energy usage.
- Clogged filters: A clogged and dirty filter can block airflow, causing your system to work harder. This leads to overheating and an early shutdown. The system will start again when it has cooled.
- Thermostat malfunctions: A faulty thermostat may misread temperatures or send incorrect signals to your AC system, causing it to turn on and off repeatedly.
- Refrigerant imbalance: A low refrigerant level can cause your system to struggle to maintain temperatures, resulting in frequent starts and stops.
If short cycling is not addressed promptly, it can lead to higher energy bills, reduced comfort, equipment breakdown, and increased repair costs.
4. Unusual Noises
Loud, jarring sounds from your air conditioning system are a sign of AC malfunction, component damage, or other serious issues. Common noises to look out for include screeching, banging, buzzing, rattling, clicking, and hissing sounds. Causes of unusual AC sounds are:
- Loose or broken components
- Debris in the fan blades
- Worn-out belts
- Electrical issues
Unusual sounds are early signs of an impending system breakdown. Ignoring them can lead to a total collapse.

HVAC Issues That Require a DIY Fix
While not every HVAC problem should be tackled on your own, some issues are safe and simple enough to handle on your own.
1. Replacing or Cleaning Air Filters
One of the common HVAC issues is a clogged and dirty air filter. Filters collect dust, debris, and allergens to improve indoor air quality; however, when they become clogged with dirt, airflow becomes restricted. Some steps to replace your air filter include:
- Turn off your HVAC system
- Locate the filter in your HVAC unit. It’s usually found behind a vent cover or inside the air handler.
- Remove the old filter and inspect it. If it is clogged with dirt and debris, then it is time for it to be replaced.
- Insert the new filters and ensure the airflow arrows are pointing in the right direction.
According to the DOE, your air conditioner filter should be replaced at least every month, or more frequently depending on usage and environmental factors.
2. Resetting the Thermostat
A malfunctioning thermostat can cause your HVAC system to malfunction. So, before calling for professional HVAC repair, double-check your thermostat settings. Steps to troubleshoot your thermostat include:
- Ensure your thermostat is set to “cool” mode.
- Verify that the temperature is set several degrees below the room temperature.
- Replace your thermostat batteries.
- If the screen is blank, check the circuit breaker for a tripped switch.
Consider installing a smart thermostat to improve AC efficiency, increase energy savings, and enhance comfort.
3. Clearing Debris Around the Outdoor Unit
Outdoor condenser units can accumulate dirt, leaves, and debris, which reduces airflow and causes your HVAC system to work harder than necessary. Here are some steps to clear the debris around your outdoor unit:
- Turn off the power to your HVAC system.
- Use a garden hose to gently spray the coil fins. Avoid using high pressure, which can damage the fins.
- Remove debris, such as leaves or twigs, from the surrounding area.
- Ensure there’s at least two feet of clearance around the unit for optimal airflow.
HVAC Issues That Require Professional Assistance
The following are some AC issues that require professional HVAC repair.
1. Electrical Repairs in HVAC Systems
Your HVAC system has multiple electrical components. At any time, these components can develop faults, such as overheated wires, burnt capacitors, or frayed wires. Attempting to repair these problems can escalate the issues, leading to higher repair bills or a fire hazard.
Some signs you may have an electrical issue include:
- AC won’t turn on
- Tripping breakers
- Buzzing or burning smells
- Inconsistent operation or short cycling
If you notice any of these signs, turn off your system and call for emergency HVAC repair immediately!
2. Replacing Blower Motors or Compressors
The blower motor pushes air through your home, while the compressor is responsible for circulating and pressurising the refrigerant. Replacing or repairing any of them requires technical knowledge, specialized equipment, and EPA certification for handling the refrigerant.
Signs of motor and compressor failure include:
- Weak or no airflow from vents
- AC hums but won’t start
- Rattling or grinding noises
- The unit runs constantly without cooling
3. Ductwork Inspection and Repair
Your ductwork is typically hidden behind walls, ceilings, or crawl spaces. However, they can get broken, torn, or poorly insulated, leading to a loss of efficiency and air quality problems. Inspecting and repairing your ductwork requires specialized equipment and professional training. Handling it yourself can increase the scale of the damage and the price of repairs and replacement.
Conclusion
When it comes to HVAC repair, the smart choice is not always obvious. When in doubt, we always recommend professional HVAC repair because it offers better service quality, efficiency, and helps prevent further issues.
