HVAC System FAQ
Turning the system fan to the ON position only recirculates air, not cool it. Air Pros reccomend allowing the system to detect when the fan should come on.
Annual maintenance or a 'Tune-Up' helps prevent your HVAC system from malfuctioning or system breakdowns. Air Pros checks your entire system including your thermostat to ensure everything works properly.
Air conditioning repairs can be costly, it’s important to learn about the common air conditioning problems so that you can take preventive measures to avoid huge repairs and costly replacement.
My Air Conditioning Unit Is Not Turning On.
Check the thermostat batteries when your Air Conditioning System is not working or turning on. Replace the batteries if they needed. If the batteries are in working, check the thermostat for proper settings. If your thermostat is on, but your Air Conditioning System is still not turning on, check the circuit breaker. If the circuit breaker is tripped, your AC won’t turn on. Turn your AC system to off then reset the circuit breaker by flipping the switch off and then on, then try turning thr system on again. If these do not work, call Air Pros for same day repairs.
My Air Conditioning System Is Not Blowing Cold Air
Your AC will not blow cold air if a dirty air filter blocks the airflow. Not replacing your air filter frequently can further freeze up the condenser unit and limit the cooling power of your HVAC System. Changing your air filter every month will help your AC unit blow cold air and run effeceintly. If you see ice or extreme water call Air Pros for same day repair service.
Air Conditioner Making Noises
An air conditioner can make different sounds depending on the type of problems. There are different reasons why your air conditioner is producing a variety of sounds:
- A refrigerant leak can produce a hissing sound.
- If you hear clicking sounds when you turn on and off your AC, it might be a relay problem.
- Thumping, rattling, or banging noises mean there is a problem with a blower or motor assembly.
- The compressor or fan motor produces a screeching noise.
- Faulty electrical components produce a buzzing sound.
Air Pros reccomends you do not attempt to correct these issues yourself. Your HVAC System may still be under warranty and can be replaced or repaired. Call Air Pros first.
AC Refrigerant Leak
When the coolant in your air conditioner starts leaking, the temperature will vary, and the unit will not perform accurately. Refrigerant leaks can result in:
- Low efficiency
- High power consumption
- Coil freezing
- Damaged compressor
- Uneven cooling
Air Pros will Inspect your air conditioner regularly for any refrigerant leaks with your annual maintence program.
Frozen Evaporator Coil
The evaporator coil freezes when your air conditioner does not receive sufficient air needed for operation. A frozen evaporator coil can make your AC freeze up and stop working. Blocked vents and ducts, dirty filters, or a faulty fan can cause insufficient airflow in the system. A clean air filter is important to maximize airflow and indoor air quality.
Electric Control Failure
When you frequently turn on and off your air conditioner, the fan controls and compressor can wear out. The condenser fan motor, the compressor, and the blower motor make an electrical connection to start the unit. A connection problem can prevent the motor and compressor from turning on. You should check the electrical connections to determine the issue.
Air Conditioner Leaking Exessive Water Outside
Water leaking outside from your AC on a hot or humid day, especially when the unit is running, is normal. Other reasons for your air conditioner to leak water outside, include:
- Dirty air filters
- Improper installation
- Blocked drain pipe
- Low coolant levels
- Broken condensate pan
