What to Do With a Noisy AC

air-conditioner-units-near-grassAir conditioners runs using motors and fans, so they can never run silently. However, the construction of standard split system air conditioners removes a great deal of the noise from the house by placing the compressor and exhaust fan outside. Inside the house, most of the sound will come from the indoor blower fan, water dripping from the evaporator coil, and the movement of air through the ventilation ducts.

This is the basic “white noise” of summer—until it isn’t. A rise in sounds from the air conditioner, and this includes a noisier outdoor unit as well, is a problem. And not just because it can be annoying. Let’s look into what can be done about a noisy AC.

Is this a specific new noise?

Are you hearing strange noises from the AC that you haven’t heard before? This could be mechanical shrieking or grinding, hissing, clanging, or clicking. A specific new noise coming from one location often indicates you need targeted air conditioning repair in Howell, MI. The sound is warning you of a problem. For example, shrieking often comes from bearings in motors wearing down, hissing from the escape of refrigerant through leaks, and clanging from a loose part inside the blower assembly. Shut down power to the AC and call for HVAC technicians to look into the problem and fix it.

Is the air conditioner making the same sounds, only louder?

If it’s a case of the air conditioner making similar sounds, but now it’s becoming real noise pollution for the house, then the problem may be an aging AC that’s ready for the recycling yard. Even if you’ve kept up with regular air conditioning maintenance each year and always had repairs done promptly, you’ll find your AC will begin to decline after 15 years or so. When the noise level rises, then call an air conditioning technician to discuss replacement options and the best way to move forward.

Has the AC always been loud?

Maybe you have an air conditioner that always made more noise than you liked. This may stem from a poor amateur installation (such as one that never properly secured the AC cabinet to the floor). Sometimes this can be fixed, and other times replacing the air conditioner is the better choice. Or you may just have an old model with bad sound dampening technology. There are many new AC units with whisper quiet operation as a special feature. Ask our cooling experts about some of the options for an air conditioner that keeps your home both cool and peaceful.

Rely on the professionals

Keep in mind that if you think something might be wrong with your air conditioner, it’s better to err on the side of caution: call for professionals. Tiny warning signs can be leading to full breakdowns, and the sooner you act on them, the more chance the repair will be a small one.
