We've been serving the Palouse area for over 20 years, and our knowledgeable technicians are equipped to handle even the most complex AC issues efficiently and effectively.

Why Do AC Problems Occur?

Air conditioners are complex systems, and various factors can lead to problems. The most common culprits include:

• Lack of Regular Maintenance: Skipping routine tune-ups often leads to preventable issues like clogged filters, dirty coils, and lubrication problems.
• System Age: Older units are more prone to wear and tear, leading to component failures.
• Component Failure: Specific parts like capacitors, compressors, or motors can wear out over time.
• Installation Issues: Improper installation can cause problems from day one.
• Refrigerant Leaks: Low refrigerant levels severely impact cooling capacity and can damage the compressor.
• Electrical Issues: Problems with wiring, fuses, or breakers can prevent the unit from operating.

Understanding these potential causes can help you pinpoint the issue, but professional diagnosis is often required for a definitive solution.

Common Air Conditioner Problems We Solve

Here are some of the most frequent AC issues we see in the Moscow area and what they might mean for your system:

1. AC Not Cooling or Blowing Warm Air

• Symptoms: The unit is running, but the air coming from the vents isn't cool, or it feels warm.
• Potential Causes:
  • Dirty Air Filter: A clogged filter restricts airflow over the evaporator coil, preventing proper cooling.
  • Low Refrigerant: Indicates a leak in the system. This is a serious issue that reduces cooling capacity and can harm the compressor.
  • Frozen Evaporator Coil: Occurs due to restricted airflow (dirty filter, blocked vents) or low refrigerant, leading to ice buildup that blocks heat absorption.
  • Faulty Compressor: The heart of the AC system; if it fails, the unit cannot cool air.
  • Thermostat Issues: Incorrect settings or a faulty thermostat can prevent cooling signals from reaching the unit.
• Basic Checks You Can Do:
  • Check your thermostat setting. Is it set to "Cool" and at a temperature below the current room temperature? Is the fan set to "Auto" or "On"?
  • Inspect and change your air filter if it's dirty.
• When to Call a Pro: If changing the filter and checking the thermostat doesn't resolve the issue, or if you suspect a refrigerant leak or frozen coil (see below), professional help is essential.

2. AC Not Turning On At All

• Symptoms: The unit is completely unresponsive when you try to turn it on.
• Potential Causes:
  • Power Issue: Tripped circuit breaker, blown fuse, or a disconnected power switch.
  • Thermostat Problem: Dead batteries, faulty wiring, or incorrect settings.
  • Motor Issues: Problems with the blower motor or condenser fan motor.
  • Electrical Control Failure: Issues with contactors, relays, or the control board.
• Basic Checks You Can Do:
  • Check your home's circuit breaker box for a tripped breaker labeled for the AC (indoor unit) or the outdoor unit. Reset if needed.
  • Ensure the power switch near the outdoor unit (looks like a light switch in a small box) is in the "On" position.
  • Check thermostat batteries if applicable.
• When to Call a Pro: If power appears to be on and the breaker isn't tripped, the problem is likely electrical or mechanical within the unit or thermostat, requiring expert diagnosis.

3. AC Running Constantly or Short Cycling

• Symptoms:
  • Running Constantly: The unit never seems to turn off.
  • Short Cycling: The unit turns on and off frequently in short bursts.
• Potential Causes (Running Constantly):
  • Thermostat Set Too Low: The thermostat may be set significantly lower than the outside temperature, making it hard for the unit to reach the target.
  • Oversized Unit: An AC unit too large for your home can cool the air too quickly, satisfying the thermostat before adequately dehumidifying.
  • Low Refrigerant: The unit struggles to cool, causing it to run longer trying to reach the set temperature.
  • Dirty Coils: Reduces efficiency, making the unit work harder and longer.
• Potential Causes (Short Cycling):
  • Oversized Unit: Can cool the space too fast, triggering the thermostat too quickly.
  • Dirty Air Filter/Blocked Airflow: Restricts airflow, potentially causing the system to overheat and shut off prematurely as a safety measure.
  • Low Refrigerant: Can cause the system pressure to drop, tripping a low-pressure safety switch.
  • Electrical Issues: Problems with the control board or capacitor can cause intermittent operation.
• Basic Checks You Can Do:
  • Adjust your thermostat to a reasonable temperature.
  • Check and replace your air filter.
• When to Call a Pro: If the problem persists after checking the filter and thermostat, it indicates a deeper issue like unit sizing, refrigerant problems, or electrical faults.

4. Strange Noises Coming From the AC

• Symptoms: Hearing grinding, hissing, rattling, buzzing, or squealing sounds from the indoor or outdoor unit.
• Potential Causes:
  • Grinding/Screeching: Often indicates issues with motor bearings (indoor blower or outdoor fan motor). This requires immediate attention.
  • Hissing: Can indicate a refrigerant leak (requires professional handling) or a faulty expansion valve.
  • Rattling: May be a loose panel, debris inside the unit, or a failing component.
  • Buzzing: Could be an electrical issue (loose wiring, contactor problem) or a failing motor.
  • Squealing: Often a sign of a worn belt (though most modern ACs don't have belts) or a failing motor bearing.
• Basic Checks You Can Do:
  • Safely turn off the unit.
  • Check around the outdoor unit for obvious debris (twigs, leaves).
• When to Call a Pro: Any unusual noise, especially grinding or hissing, should be investigated by a professional promptly to prevent further damage or safety hazards.

5. Strange Smells From the AC Vents

• Symptoms: Noticing musty, moldy, burning, or electrical smells when the AC runs.
• Potential Causes:
  • Musty/Moldy: Often indicates mold or mildew growth in the ductwork or on the evaporator coil due to excess moisture.
  • Burning: Could be an electrical problem (burning wire, failing motor) or a clogged filter allowing dust to burn on heating components (even in AC mode sometimes).
  • Electrical/Burning Plastic: A strong indicator of an electrical component overheating or failing.
• Basic Checks You Can Do:
  • Check your air filter; a very dirty filter can sometimes produce odors.
• When to Call a Pro: Burning smells require immediate attention as they can indicate an electrical fire hazard. Musty smells warrant investigation to prevent health issues associated with mold.

6. Water or Refrigerant Leaks

• Symptoms: Puddles of water near the indoor or outdoor unit, or ice buildup on the indoor coil or refrigerant lines.
• Potential Causes (Water Leaks):
  • Clogged Condensate Drain Line: The most common cause. Humidity condensed from the air cannot drain properly and backs up, overflowing the drain pan.
  • Frozen Evaporator Coil: When the coil freezes, it eventually melts, creating excess water that may overflow the drain pan.
  • Cracked Drain Pan: Less common, but can happen in older units.
• Potential Causes (Refrigerant Leaks):
  • Pinhole Leaks: Can develop in refrigerant lines over time.
  • Faulty Service Valves: Leaks can occur where service valves connect.
• Basic Checks You Can Do:
  • You can check the condensate drain pan (usually under the indoor unit) for overflow. You should not attempt to handle refrigerant yourself.
• When to Call a Pro: Water leaks can cause significant property damage if not addressed. Refrigerant leaks require licensed professionals who can safely handle and recharge the refrigerant, which is also an environmental concern. Ice buildup is also a sign that needs professional diagnosis.

7. Poor Airflow From Vents

• Symptoms: Weak or inconsistent airflow from supply vents throughout your home.
• Potential Causes:
  • Dirty Air Filter: The most common cause.
  • Blocked or Leaky Ductwork: Obstructions or leaks in the ducts reduce the amount of air reaching your rooms.
  • Failing Blower Motor: The motor responsible for pushing air through the ducts may be weakening.
  • Closed Vents: Ensure all supply vents are open.
  • Frozen Evaporator Coil: Ice buildup restricts airflow.
• Basic Checks You Can Do:
  • Check and change your air filter.
  • Ensure all supply vents are open and not blocked by furniture.
• When to Call a Pro: If airflow doesn't improve after checking filters and vents, you may have a problem with your ductwork, blower motor, or a frozen coil requiring professional repair.

The Real Impact of Ignoring AC Problems

Putting off AC repairs might seem like a cost-saving measure in the short term, but it can lead to significant problems and higher costs down the road. Ignoring issues can result in:

• Higher Energy Bills: A struggling AC unit works harder and runs longer to cool your home, dramatically increasing energy consumption and your monthly utility bills. An inefficient unit can waste up to 40% more energy.
• Permanent System Damage: Minor issues, if left unaddressed (like low refrigerant or a failing motor), can cause cascading damage to other components, including the expensive compressor. This can lead to premature system failure and the need for costly replacement.
• Reduced Comfort: Beyond just warm air, a malfunctioning AC can lead to humidity issues, uneven temperatures, and poor indoor air quality.
• Potential Health Issues: Mold growth from condensate issues can release spores into your air, impacting respiratory health. Electrical problems pose fire hazards.

Addressing AC problems promptly not only restores comfort but also protects your investment, saves money on energy, and prevents more serious (and expensive) breakdowns.
