Frequently Asked Questions About AC Repair

What is a condenser coil, and what role does it play in my AC unit?

The condenser coil is a vital component of your outdoor AC unit. It works in tandem with the evaporator coil to complete the cooling cycle. The condenser coil releases the heat absorbed by the refrigerant in the evaporator coil to the outside air. As refrigerant passes through the condenser coil, it condenses from a high-pressure gas to a high-pressure liquid, releasing the heat it absorbed indoors. Keeping the condenser coil clean and free of debris is essential for its efficient operation.

How do I choose the right size AC unit for my home?

Choosing the correct AC unit size is crucial for energy efficiency and adequate cooling. An undersized unit will run constantly, struggling to cool your home, while an oversized unit will cycle on and off frequently, wasting energy and shortening its lifespan. Factors that determine AC size include the square footage of your home, insulation levels, climate zone, window size and efficiency, number of occupants, and heat-generating appliances. Don't guess! Consult an HVAC technician to perform a Manual J load calculation to determine the precise cooling capacity your home needs.

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 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.

Never attempt to add refrigerant yourself. Consult a licensed HVAC technician.
