Donโt Ignore These A/C Noises in Sacramento
Weโve all spent the night in a strange place only to be kept awake by a cacophony of odd noises. Itโs not just the sound of someone elseโs significant otherโs snoring, either. From the sound of wind on the windows to the beep of the microwave, everything is different than weโre used to, and might even leave us wondering if the place is haunted. But what if your own homeโs air conditioning doesnโt sound like it used to? Donโt wait for it to change its tune; get in touch with Ace Plumbing Heating and Air Conditioning forย HVAC repair in the Sacramento area.
You should reach out to a professional if your air conditioner is making a pulsating noise or making a noise when off.
Normal Air Conditioner Sounds
Like anything mechanical, central air conditioners (and forced air heat systems) have a characteristic sound when they operate. When the thermostat hits its set point, for instance, youโre likely to hear clicks from the thermostat and controls. Youโll also hear the compressor and air handlers powering up, followed by the white noise of air moving through ducts, registers, and returns. When the process stops, youโll hear everything powering down, some more clicks, and the return of silence. So far, so good.
Unusual Air Conditioner Noises
Not every AC sound is normal, so here are some noises you should keep an ear out for. Theyโre often an indication that somethingโs gone wrong with yourย New Window AC unit.
Grinding or Humming
Some humming is to be expected when youโve got electric motors running. But if that humming becomes much more pronounced or takes on a new urgency, pay attention. If that hum turns to a grinding or banging sound, shut the system down and call us immediately. Thatโs often an indication that a part is sticking or is off-kilter. If ignored, you may find yourself with an overheated unit or a fire.
High-Pitched Sounds
Sometimes youโll hear a screeching or high-pitched squealing sound from your air conditioner. Your AC uses belts and bearings, and as they reach the end of their service life, they get noisy. Here again, donโt wait to call for service, because if these parts break they have a tendency to take out other parts of your system.
Hissing
Airflow has a characteristic sound as it makes its way through your system. But if youโre a long way from a vent or grille and youโre hearing a hissing sound, there are a few potential causes depending on the location. Refrigerant leaks, overpressure in the compressor, valve leaks, or a bad seal in a duct can all lead to hissing noises. Best case scenario: your system loses efficiency. Worst case: it breaks down.
Repeated Cycling
Once your home cools down, your air conditioner shouldnโt have to run for a little while. If itโs short-cycling (turning on and off at short intervals), there can be a number of underlying causes, including faulty wiring or a broken thermostat. This puts unnecessary wear and tear on your system and can also send your utility bill through the roof, so it shouldnโt be ignored.
