Frequently Asked Questions About AC Repair

Why is my AC fan not spinning?

The cause of a malfunctioning AC fan needs professional diagnosis. Here are some possibilities:

• Faulty capacitor:
The capacitor gives the motor a boost to start. A faulty capacitor can prevent the fan from starting.
• Malfunctioning motor:
The fan motor itself might have burned out or seized..
• Worn-out belt:
If your AC has a belt-driven fan, a worn or broken belt can prevent it from spinning.
• Electrical issues:
Wiring problems or a tripped circuit breaker can cut off power to the fan.
• Frozen unit:
Ice buildup might prevent the fan from turning freely.

It's essential to contact a qualified HVAC technician to diagnose the issue and ensure safe and proper repair. .

How can I improve my AC's energy efficiency?

Boosting your AC's energy efficiency can lead to significant savings. Consider these tips:

• Regular maintenance:
Schedule professional tune-ups at least once a year to optimize performance.
• Programmable thermostat:
Automate temperature adjustments to save energy when you're away or asleep.
• Seal air leaks:
Caulk and weatherstrip windows and doors to reduce drafts.
• Proper insulation:
Ensure adequate attic, wall, and floor insulation to minimize heat transfer.
• Ventilation:
Improve ventilation to remove excess heat and humidity.
• Energy-efficient appliances:
Choose appliances with the Energy Star label to reduce overall energy load.
• HVAC zoning:
Consider zoning to better regulate temperature different areas.

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.

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.
