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 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 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, helping it thaw more quickly..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 qualified HVAC professional promptly for diagnosis and repair.Never try to chip away ice from the coil; this can damage delicate fins.

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 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.
