outdoor ac unit humming

Air conditioners always make noise because of all their motors and moving parts. But if your A/C’s noise volume has increased, then you should be concerned. There may be an issue—and the longer you wait, the more damaged your AC can become. So, sad to say, you may need a Phoenix-area A/C technician to repair your A/C. But what’s causing the loud noise? Depends on the noise. Let’s focus on 5 common noises and what’s causing them. A buzzing noise indicates some sort of electrical issue such as loose wiring, arcing/sparking connections, or burning at the fan contactor relay switch. Buzzing at the outside fan motor may mean a failing motor. Best-case scenario: some debris, like a stick, fell into the outside unit and the fan is kicking it around. Turn off your air conditioner and inspect the outside unit for any debris. Middle-case scenario: you have loose bolts, screws or fasteners that are causing vibrations when your AC runs. Worst-case scenario: there’s an issue with the compressor, the heart of your air conditioner.

If the noise is coming from within the compressor, it may need replacing. Unfortunately, replacing this part is terribly expensive. If you have to replace the compressor, see if your parts warranty covers it. Both your inside and outside A/C units have fan motors. A humming or grinding noise likely means that one or both fan motor bearings are bad or need lubrication. Keep these bearings lubricated by getting professional A/C maintenance once a year. Squeaking could be a simple loose fan belt on the inside unit. You’ve probably heard a similar squeaking from your car’s belts. Again, A/C maintenance is your friend here. If you hear a hissing or bubbling noise and your A/C isn’t cooling your home well, then you probably have a refrigerant leak (the noise is the refrigerant escaping the leak). A professional technician needs to fix the leak ASAP. If your A/C gets too low on refrigerant, the compressor can become damaged. Remember: it’s the heart of your A/C. Do you live in the Phoenix metro area?

You check your outside unit and notice that the outdoor unit is humming like normal but the fan isn’t spinning and is making a buzzing noise. So, what exactly is the problem? If your outdoor A/C unit is humming but the fan isn’t running, that most likely means you have a bad fan capacitor which is a common problem in the Tallahassee, FL area and everywhere else in the USA.

We’ll show you that cheap trick later in this article. However a little education can go a long way so first let’s take a look at why capacitors are so important in the first place. A capacitor is a small, cylinder-shaped metallic object that sits on the side of your outdoor unit. It acts like a battery and stores large amounts of energy. Tallahassee Air Conditioning & Electrical stocks both standard capacitors and turbo capacitors for heavy demand systems.
12.5 ton ac unit price In the case of air conditioners, capacitors are used to kick-start the compressor, the outdoor fan motor, and the blower fan (indoor unit fan). You see, large appliance motors require up to 5 or 6 times more energy at startup than they require when running continuously. Capacitors offer that extra jolt of electricity needed to get motors started and/or to run continuously. Why did my capacitor “go bad”?

Just like a battery, your capacitor will weaken and lose the ability to hold electrical charge over time. They’ll also have a shorter lifespan if they suffer some sort of damage, like from high temperatures or high voltage such as lightning strikes. Some of the visual signs of a bad capacitor include: So, if the capacitor connected to your fan motor goes bad, the fan will fail to start. And this prevents your unit from moving the heat from inside your home to the outdoors (which explains why the air coming from your vents is warm instead of cool). Eskimo Joe’s short-term solution for a bad capacitor Need a quick fix for your failed fan motor capacitor? Turn on the A/C unit and take a long, thin object (a stick or screwdriver will work fine) and use it to push the fan blades inside the compressor. (The Compressor is Outside) This should provide the “kick” the fan motor needs to get up to speed. Please be sure to take safety precautions when doing this so that nobody gets hurt.

Note: if this doesn’t get your fan running, you most likely have a bad fan motor and will need to have Tallahassee Air Conditioning & Electrical, LLC The long-term solution for a bad capacitor If the capacitor connected to your fan motor is weak or has finally died and won’t start your fan, you need to have a professional replace it as soon as possible. When a capacitor fails, the motor it is connected to will still try to come on. And most of the time, the motor won’t be able to start on its own. This stalling can cause the motor to burn out and need expensive replacement soon. The sooner you are able to replace the capacitor, the more money you will save yourself in the long run. Note: Although it is possible to replace a capacitor on your own, we don’t recommend it unless you have experience working with the electrical components of your air conditioner.
