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.
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.
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.
How do I reset my AC unit?
Sometimes a simple reset can resolve minor AC issues. Here's how to reset most residential AC units:1. **Turn off the AC at the thermostat:** Set it to the 'off' position.2. **Turn off power at the breaker panel:** Locate the circuit breaker that controls your AC unit and switch it to the 'off' position.3. **Wait 5-10 minutes:** This allows the system to completely power down and reset any internal electronics.4. **Turn the breaker back on:** Flip the circuit breaker back to the 'on' position.5. **Turn on the AC at the thermostat:** Set the thermostat to your desired cooling temperature.If the problem persists, it's likely a more serious issue, and you should contact a qualified HVAC technician. DIY electrical repairs on AC units are highly discouraged.
