Cooling & Air Conditioning Services in Los Gatos, CA

Possible Causes:

• • Tripped circuit breaker or blown fuse
• • Dirty or clogged air filter restricting airflow
• • Thermostat malfunction or incorrect settings
• • Low refrigerant levels
• • Faulty capacitor or contactor
• • Compressor failure
• • Condensate drain pan full (safety switch activated)

What to Do:

Start with the basics: check your circuit breaker, ensure the thermostat is set to "cool" and below room temperature, and replace your air filter if it's dirty. Check the outdoor unit for debris or blockages.

When to call immediately: If the AC still won't work after checking basics, or if you notice refrigerant leaks, strange noises, or electrical issues, contact us right away. These problems can worsen quickly and may indicate serious issues.

Possible Causes:

• • Dirty or clogged air filter
• • Blocked or closed air vents
• • Dirty evaporator or condenser coils
• • Leaky or poorly insulated ductwork
• • Undersized AC system
• • Blower motor problems
• • Refrigerant leaks

What to Do:

Check and replace your air filter, ensure all vents are open and unobstructed, and check the outdoor unit for debris. If airflow remains weak, the issue may be more complex.

Professional solution: We can perform a comprehensive evaluation including coil cleaning, ductwork inspection, airflow testing, and refrigerant level checks. Regular maintenance prevents most airflow problems.

Possible Causes:

• • Dirty air filter reducing efficiency
• • Dirty evaporator or condenser coils
• • Low refrigerant levels
• • Leaky ductwork wasting cooled air
• • Aging, inefficient AC system
• • System cycling too frequently
• • Poor insulation or air leaks in home

What to Do:

Replace your air filter, ensure vents aren't blocked, and check thermostat settings. If bills remain high, the issue likely requires professional diagnosis.

Professional solution: We can perform an energy audit, clean coils, check refrigerant levels, inspect ductwork, and identify all sources of energy waste. Regular maintenance significantly improves system efficiency and performance.

Possible Causes:

• • Worn motor bearings (squealing)
• • Loose or damaged blower wheel
• • Debris in blower compartment
• • Loose panels or ductwork connections
• • Compressor problems (grinding)
• • Refrigerant line issues (hissing)

What to Do:

Some operational noise is normal, but unusual or loud noises often indicate problems. Squealing typically means bearings need attention, while grinding may indicate compressor issues.

When to call: If noises are new, getting louder, or accompanied by other problems, schedule service immediately. Ignoring unusual noises can lead to more expensive repairs or complete system failure.

Possible Causes:

• • Clogged condensate drain line
• • Frozen evaporator coil (low refrigerant or airflow issues)
• • Damaged drain pan
• • Improper installation or slope
• • Refrigerant leaks causing freezing

What to Do:

If you see water pooling or ice on the unit, turn off the AC immediately to prevent further damage. Check the condensate drain line for blockages if accessible.

Professional solution: We'll clear the drain line, check for refrigerant leaks, inspect the evaporator coil, and ensure proper drainage. Water leaks can cause significant damage if not addressed promptly.
