5 most common Ruud commercial air conditioner repair problems

1. Bad capacitor – fan blowing warm air

If the air coming from your vents is not cold and your thermostat appears to be functioning properly, find your outside unit to see if it’s working. There are two parts—the fan motor and the compressor. Both are audible to a trained ear. The compressor is like a deep hum, like a refrigerator running, and the fan naturally generates a whirring noise. Your hand should feel warmer than the ambient air when you hold it over the fan. There is a significant likelihood that your capacitor is damaged if the outside unit is buzzing or humming but nothing is turning or blowing.

The electric motors in your air conditioner are started and run by capacitors. They specifically provide the motors a boost of energy during the initial phase to get them going. Capacitors deteriorate with time, and if they are not replaced, they will eventually “blow,” rendering them inoperable and occasionally leading to additional problems inside the device.

2. Low refrigerant – air not keeping up

Your air conditioner’s refrigerant transports heat to chill your system. The system will struggle to keep up, it could freeze, and it won’t be able to effectively chill your building if the refrigerant level is too low.

The majority of low refrigerant cases involve a slow leak, so if you pay attention, you may notice the problem as the symptoms get worse and worse. You might find that your air conditioner runs longer and longer and works harder to achieve the temperature you have set.

It is not difficult to add more refrigerant to get your system cooling correctly again. The issue is that there is a reason your system is short on refrigerant. Even if the leak is gradual, refrigerant is still leaking in some way. This typically happens in the evaporator coil, therefore if the leak is large enough, it may be best to either replace the evaporator coil or, if the system is sufficiently old, the entire system.

3. Clogged condensation drain line – no air and blank thermostat

Your house is being dehumidified as it is being cooled. The removal of moisture occurs concurrently with the cooling of the air. This moisture needs to be adequately captured and drained outside of your building. As such, a PVC drain line is routed from your system to the outside after installation. The issue is that as time goes on, algae and other substances have a tendency to constrict and plug the drain line, preventing effective drainage. As a result, instead of soaking through your roof or spilling onto the floor, it begins to back up inside the unit and finally fills up a secondary drain pan. As they fill up, a safety switch in these auxiliary drain pans will turn the unit off.

Many things can happen when the safety switch is activated, depending on how it is wired. Most frequently, the safety switch will cut off power to the thermostat, causing it to go blank. As an alternative, the condensing unit will be turned off while the blower and thermostat remain off.

If you’re feeling brave, you can locate your air handler/evaporator and check the drainage by raising the SS2 valve or looking for water in the pan. You’ve identified the issue if the appliance turns on when you lift the SS2 switch or if water is visible in the pan. Although professionals frequently use compressed air or other techniques to get things moving, you might try to clear the drain line on your own.

4. Bad Condenser Fan Motor or Compressor – air not working and breaker tripped but won’t reset

Your HVAC system’s exterior “condensing unit” houses both of these components. It’s probable that either your compressor or condenser fan motor is broken if you don’t hear both operating while your system is on, you have a tripped breaker, or you hear screeching or grinding. These motors often fail in a couple of ways but you won’t be able to solve any of these problems on your own, therefore you’ll need to consult a specialist like Air In Motions Ruud commercial air conditioner repair professional.

5. Failing blower motor – no air and you smell something burning or hear banging

The blower motor moves air through your ductwork. Although they are among the top 5 in terms of repair costs, blowers are rather reliable. They frequently reside in hot or humid environments and occasionally don’t receive the attention they need, such as lubricating their bearings or keeping them clear of dirt and debris. Older motors also feature capacitors to aid in starting, and when these capacitors get older or wear out, the motor is put under more stress during starter.

The blower is most likely to blame if you notice an electrical burning smell in your ductwork or hear spinning pounding or grinding noises. You can’t really fix anything yourself, but you should turn off your machine to avoid any more harm or potential fire, and call your Air In Motion Ruud commercial air conditioner repair professional.
