What Is Your HVAC System Trying To Tell You?
HVAC systems contain microprocessors that control the heating and cooling operation of the unit. As winter ends, flowers bloom, trees start to bud, and temperatures increase with the onset of spring going on to summer. In many homes, this often involves using air conditioning systems to enhance comfort.
Is your system faulty?
It is important for homeowners to look out for early warning signs of AC malfunctions. This does not only give you a better idea on whether to replace your air conditioning system, but it also prevents you and your family from having to live in discomfort during summer as temperatures rise.
A defective air conditioner can be a sign of compressor problems. A malfunctioning compressor can make the AC system not to start or function as required. The malfunctioning compressor will also make the AC to shut down abruptly. An HVAC system that emits little or no cool air could have a malfunctioning AC system. A defunct AC compressor can also cause the fuse to burn.
A faulty compressor can make the air conditioner use more power than usual even when the AC system seems to be operating normally. This may lead to high energy bills.
A defective compressor will make the air conditioner produce noises including clanking, banging, or buzzing sounds. The unit may produce “hums” but fail to start if the compressor is not in working condition.
AC systems contain contactors that control how the units power on and off. Contactors have two metal strings that can cause the AC unit to fail to shutdown when they interlock. In such cases, homeowners are forced to pull the plug or flip the breaker of their AC units to shut them down.
Failure to Start
A defective contactor may cause an AC unit to fail to start. If the thermostat of your AC unit is working but the system is not, it is probably because of a malfunctioning contactor. It could also be a sign of low electricity supply to the AC unit.
Sudden Shutdown of the AC Unit
An AC system with a faulty contactor will shutdown suddenly to avoid blowing the monitors or overheating. However, you may use the reset button on your air conditioner or heater to turn it back on. Be sure to observe the unit to see if it is working after the sudden shutdown. Call HVAC contractors if the unit suddenly shuts down again.
Frost in the air conditioner is another sign of contactor problems. AC units often develop frost when they use maximum power for a prolonged period, which results in condensation inside the unit. In such cases, switch off the unit and allow it to defrost before you consider replacing it. You can learn additional information at Cozy Comfort Plus.
