But what happens when the source of their relief, their air conditioner, starts making weird noises? That’s not so relaxing! It’s not uncommon for air conditioners to make a variety of strange sounds. What’s important is the type of sounds that your air conditioner is making, since each sound can indicate a different issue.

To learn more about why your AC is making that weird sound (and how to make it stop), read on. If your unit is making a high pitched squealing noise, the issue is usually either the belt connecting the motor to the blower has slipped or the bearings on your condenser fan’s motor. Most newer air conditioners don’t use a belt system, so if your unit is older, that is likely the problem. If this is the case, you’ll hear the sound both inside of your home and outside of your home. If this issue sounds like what you’re experiencing, the belt will need to be replaced. If you have a newer unit, it’s more likely that the issue is the bearings on your condenser fan’s motor. Newer units utilize direct-drive motors without belts, which pull air across the condenser coils in your compressor. If this is the case for your air conditioner, you may hear squealing or grinding from your outdoor unit, which indicates that the motor needs to be replaced. With both of the issues outlined above, we would advise you to call a professional to repair your air conditioner.

After you’ve been using your air conditioning for a while, those feet can disintegrate or crack, which makes the compressor lose balance and start to make a buzzing noise when in use. As they’re being used to cool your home, air conditioning units can actually freeze up—this may sound counterintuitive, but it’s true! Your AC can become frozen if refrigerant begins to leak from the unit, which often begins emitting a buzzing sound as a result. Finally, the issue at hand could be a malfunctioning compressor, which is the part of the unit that pressurizes and cools down the refrigerant that then cools your home. A buzzing noise may mean that your compressor isn’t working correctly or that the electrical voltage of your unit is not right.

Carl’s Corner – Auto Repair Help DIAGNOSE – I HEAR A LOUD SQUEAL WHEN A/C IS TURNED ONBy Carl A loud squeal is produced when the A/C is turned on. This symptom is usually caused by a loose or worn air conditioning compressor belt. When the A/C is activated the compressor is engaged. This places a load on the engine and the drive belt that rotates the compressor. If the belt is loose or worn the belt can slip on the compressor pulley and emit a loud squeal. The drive belts should be inspected for proper tension and wear. A properly tensioned belt should have aproximately 1/2″ of deflection at its greatest span between pulleys. Inspect the belt for wear. Belts can become glazed on the inside drive surface which can cause them to slip, which produces the loud squeal. Some vehicles use an automatic tensioner that contains a large spring that keeps constant pressure on the belt. This system automatically tensions the belt to the proper tension. This system is often used on vehices that use a serpentine belt.

This type of system uses one belt to drive many accessories. PRECAUTIONS, TIPS, and NOTES Use caution when working around hot or rotating engine parts. Given the recent severe weather, it likely doesn’t come as surprise that many people are discovering their outdoor AC units suffered damage.

After a storm of this size impacting our weather, yes, you should be worried if your AC is suddenly showing signs of malfunction. But what exactly qualifies as an emergency—when should you give us a call? One of the most common emergency calls that we receive for air conditioners is that the system is making a screeching noise. In the best case scenario, this is simply caused by a loose fan belt. However, it may also be the sign of a compressor that’s working at a dangerously high level of pressure, which necessitates a call right away.

Of course, you may not know the difference, and that’s okay. Diagnosing the problem with your cooling system is our job, so give us a call whether it’s a screeching you hear, or are bothered by banging, hissing, or even a humming noise you’ve never heard before. Burning smells coming from any part of your AC system is never a good sign. In most cases, this is indicative of an electrical problem. If you notice this smell, immediately turn off your system and be sure to call us right away. Another common call we receive is in regards to air flow—either there’s not enough or your AC system isn’t cooling as it should. This could be the sign of a refrigerant leak or a number of other problems. First, check your thermostat to be sure the settings are correct. If they are and you see no other apparent cause for this issue, then you may have an emergency situation on your hands which warrants a call to our team. For quality AC repairs in Ft.
