Frequently Asked Questions About AC Repair

Experiencing problems with your air conditioning? Concerned about rising energy bills due to inefficient cooling? Find answers to common questions about AC repair and connect with qualified HVAC technicians in USA.

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.
Contact an AC repair service to fix a fan problem. Don't attempt electrical repairs yourself.

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.

How often should I replace my AC filter?

Replacing your AC filter regularly is essential for both air quality and system efficiency. A general guideline is to change or clean your filter every 1-3 months. However, consider changing it more frequently (monthly) if:
  • You have pets.
  • You or your family members suffer from allergies or respiratory issues.
  • You live in a dusty or polluted environment.
  • You use your AC frequently.
Regular filter changes optimize performance and indoor air quality. Consult your system's manual or an HVAC professional for optimal recommendations.

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.
