Frequently Asked Questions About AC Repair

What causes an AC unit to leak water inside?

Water leaking inside from your AC unit usually indicates a problem with the condensate drainage system. Here are some common causes:

• Clogged condensate drain line:
Algae, dust, and debris can clog the drain, causing water to back up and overflow.
• Cracked drain pan:
The pan collects condensation. A crack allows water to leak out.
• Disconnected drain line:
The line may have become disconnected from the unit or the drain.
• Frozen evaporator coil:
A coil frozen due to restricted airflow can lead to leaks.
• Low refrigerant:
This can cause ice to form on the evaporator coil, which then drips.

It's best to have a professional resolve AC water leaks.

Can a dirty air filter cause my AC to freeze up?

Yes, a dirty air filter is a common culprit behind a frozen AC unit. The restricted airflow caused by the dirty filter makes it difficult for the evaporator coil to absorb enough heat. This can cause the moisture in the air to freeze on the coil, forming a layer of ice that further restricts airflow and can eventually damage the compressor. Changing or cleaning your AC filter regularly (every 1-3 months) is a simple preventive measure to avoid this problem.

What are the signs of a bad AC compressor?

The compressor is a vital component of your AC system, and its failure can be a major headache. Watch out for these signs of a failing compressor:

• Loud noises:
Unusual sounds like clanking, grinding, or rattling from the outdoor unit indicate potential problems with the compressor.
• Warm air from vents:
If the air from the vents isn't cool, it could mean the compressor isn't functioning properly.
• Reduced cooling capacity:
Your AC unit may be running constantly, but the house doesn't cool down as it should.
• Refrigerant leaks:
Leaks can occur at the compressor and lead to reduced cooling efficiency.
• Tripping circuit breaker:
A failing compressor can draw excess current, causing the breaker to trip repeatedly.

If you suspect compressor issues, call a qualified HVAC technician for diagnosis and repair or replacement options.

What does SEER mean in AC units?

SEER stands for Seasonal Energy Efficiency Ratio. It's a measure of how efficiently an air conditioner cools your home over an entire cooling season. It is calculated by dividing the total cooling output (measured in BTUs) by the total electrical energy input (measured in watt-hours). A higher SEER rating indicates greater energy efficiency. For example, an AC unit with a SEER rating of 16 is more efficient than one with a SEER of 14. Modern, energy-efficient AC units have SEER ratings ranging from 14 to 26. The higher the rating, the less energy the AC unit consumes, resulting in lower energy bills.
