Frequently Asked Questions About AC Repair

Is your AC unit not cooling properly? Are you hearing strange noises or noticing unusual smells? Find answers to common questions about AC repair and connect with qualified HVAC technicians in USA.

How do I fix a frozen AC unit?

If you discover your AC unit is frozen, here's what to do::1. **Turn off the cooling system:** Set the thermostat to 'off' to stop the cooling cycle and prevent further damage to the compressor.2. **Turn on the fan:** Set the thermostat's fan setting to 'on' or 'auto.' This circulates warmer air over the frozen coil, promoting faster defrosting.3. **Find and address the underlying cause:** Inspect the air filter and clean or replace it if it's dirty. If the filter is clean, the problem might be more complex, such as a refrigerant leak.4. **Call an HVAC technician if the problem persists:** If the unit freezes up again after thawing, or if you suspect a refrigerant leak, contact a licensed service provider promptly for diagnosis and repair.Never try to chip away ice from the coil; this can damage delicate fins.

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 also cause water to leak. .
  • Low refrigerant:
  • This can cause ice to form on the evaporator coil, which then melts and leaks.
It's best to have a professional resolve AC water leaks.

What is a SEER rating?

SEER stands for Seasonal Energy Efficiency Ratio. It measures the cooling output of an air conditioner over a typical cooling season, divided by the energy it consumes in watt-hours. In simpler terms, it tells you how efficiently an AC unit converts electricity into cooling power. A higher SEER rating signifies a more energy-efficient unit, resulting in lower energy consumption and utility bills. Modern air conditioners typically have SEER ratings ranging from 13 to 26. When replacing your AC, look for a unit with a high SEER rating to maximize energy savings over the long run.

How can I tell if my AC unit is low on refrigerant?

A few key signs indicate low refrigerant:
  • Warm air blowing from vents:
  • If the air isn't cool, low refrigerant is a likely culprit.
  • Ice formation:
  • Freezing on the refrigerant lines or outdoor unit signals a pressure drop caused by leaks.
  • Hissing or bubbling sounds:
  • These noises can indicate escaping refrigerant.
  • Increased energy bills:
  • The system strains to cool with less refrigerant, using more energy.
Contact a professional HVAC service to address low refrigerant. DIY attempts can be hazardous and ineffective.
