Isn't the air compressor just charging or is this a new noise that you didn't hear before. If it isn't broke don't fix it. It could be a valve that isn't opening and closing properly. Use a little pneumatic lubricant on any parts you feel confortable getting into. Don't disassemble anything unless you know how to put it back together. Pay attention to direction of valve spools.

I have a 2006 Mazda3. I noticed whenever my air conditioner or heat is on it makes a sound like a lawn mower when I acceralate. Any ideas of what this could be ?


Well, I think you can rule out the AC/heater fan inside the car. That would make noise even just sitting in the driveway.

Many/most vehicles are designed to run the AC compressor not only when the AC is on but also when the defroster is on. This is to keep the AC compressor lubricated through the winter months also.

It should not be a belt problem as that belt is always turning anyway which should then rule out the pulley bearing at the AC compressor.

I do suspect your problem is a major internal failure of the AC compressor. This can be easily checked by a technician [or yourself if qualified]. Locate the electrical connector at or to the AC compressor. Two people: With the AC turned on, in park, increase the engine speed so you can here the noise. Disconnect the AC compressor electrical connector. If the noise stops instantly, the compressor has failed. A quite expensive repair. Have a reputable shop locate a re-manufactured compressor for you. That will help some on the cost.
Bestaluckto you!!

Mower makes chugging noise like it's gonna stall


Check the air filter to see if it is clogged. If you can park it somewhere that does not kick up dust or grass, then you can remove the air filter and then start it and see if that is what was keeping it chugging. If running smooth, tie the dead man lever or get someone to hold it and then slip the air filter back in place, if it chugs you know that is what it is and just needs replaced.

I hope this helps.

My air conditioner is on but not blowing cold air and buzzes


The compressor is not starting. The buzzing noise you hear is the compressor trying to start and then the thermal overload trips. When it cools it will try to start again. Could be a bad capacitor or the compressor is bad. These two units need to be tested to see which one is bad. A capacitor is inexpensive. If it's the compressor it will be cheaper to buy a new AC.

I noticed some straining noise coming from my a/c unit today. The fan on top of the condenser runs fine but as soon as the compressor tries to kick on the fan stops for a split second and you get a kind of...


You amy ahave a bvad capacitor on the outside unit. It starts the fan and the compressor. You can change this yourself. Open the outside panel and you will see a silver canister with terminals out the top. Replace this and I think your problem will go away. On the cap. it will say something like 30uf 5uf 370 ot 440 Just get these numbers and get a new one. Russ

Floods while mowing-remove air filter -gas running out air intake.


First, go outside and stand next to the lawn mower. Then as hard as you can kick it. Keep kicking it until you feel better. Now go down to your local Sears and tell them that you need a new lawn mower and watch all of those guys scramble to make the sale.
Happy Shopping.

Compressor making noise and freezer is kicking cold air out but


Sounds like the start relay, start capacitor and overload have become defective. Turn it off to prevent further damage to the compressor internal overload. Check to make sure the condenser fan and the evaporator fans are running and get back with me with an answer yes or no. Thanks, Sea Breeze
If the model number you have above your post are correct I will also send you part numbers and hot to replace.

Ac starts kicks on and off every couple mins


Sounds like the compressor is the one making the "NOISE". If the sound sounds like something trying to start, then kicking off, its probably the compressor and not the fan. Hence no cool air.
