my ac unit doesn't turn off

We hear Phoenix-area homeowners ask, “Why does my air conditioner keep tripping the breaker at the control panel?” First off, if this keeps happening then don’t turn the circuit back on. The circuit breaker’s job is to keep your home and appliances safe by shutting off the flow of electricity when the current flow gets too high. If it keeps tripping, something needs to be fixed. If the air conditioner is the source of the tripping, it may be overheating. When an air conditioner overheats, it draws more amps (a measurement of electrical current) from the circuit. That may be pushing the circuit past the number of amps it was meant to handle. So the breaker usually trips after the air conditioner has been running for awhile. So now we need to know what’s causing your air conditioner to overheat. 1) Dirty air filter: Dirt on the filter impedes air flow. This causes the AC to run longer to circulate enough cool air to achieve the temperature you want.

This then causes the air conditioner to overheat. Change the filter and see if that helps. 2) Dirty condenser coils: The condenser coils are in your air conditioner’s outside unit. Refrigerant runs through these coils. A fan blows over the coils to dissipate the heat that the refrigerant absorbed in your home. This is done so the refrigerant can flow back into the inside air conditioning unit and absorb more heat from your home’s air. (See how an air conditioner works exactly.) But if the condenser coils are covered in dust, dirt and leaves, then the coils can’t properly dissipate the heat. So the air conditioner has to work harder and longer to cool your home and overheats as a result. In the Phoenix area, it’s easy for air conditioners to get covered in dust after haboobs (dust storms). Learn more about why you need to clean your condenser coils. You could wash the coils off, or you could have a contractor do it professionally as part of a pre-season air conditioner maintenance visit / A/C tune-up.

Spring is the perfect time for one of those! 3) Not enough refrigerant: Without enough refrigerant, the air conditioner has to work longer to cool your home. The air conditioner overheats in the process. You’ll know if you don’t have enough refrigerant if the air your air conditioner puts out isn’t very cold.

Try changing the filter and cleaning the coils. If that doesn’t work: Call a professional to repair the air conditioner.Updated The cause of the smell is fungus, mold, and/or bacteria living in your vehicle's climate control system (typically they congregate in the evaporator core and/or near the condenser in your A/C unit). These critters move into these areas because it's a moist enclosed space, and while some cars have a bigger problem with this than others (some models are notorious for this problem), it's very common.There are a few things you can do to eliminate the problem.Starting now, turn off the A/C at least 2 minutes before you shut off your vehicle - preferably 5 minutes - but leave the fan on. Just get in the habit of shutting your A/C off at a certain point on your commute. This way, your system will dry quite a bit before you shut off.Buy a bottle of lysol antiseptic spray. Start your car, turn on the A/C system full blast, and make sure it's set to pull air from the outside (the recirculate button should be off).

Finally, roll down all the windows. Then, start spraying the lysol into the exterior air vents between your hood and your windshield. I'd spray for 20-30 seconds, wait a minute, then repeat until about 10 minutes have gone by. Then I would let the air conditioner run with the windows down for at least another 10 minutes before shutting down.If step #2 doesn't work (and it won't always work), your dealership can try a foaming system cleaner sold by BG products. While some people say that this stuff is no better than lysol, I have seen it work when lysol didn't.Worst case, you can ask your dealer to remove the smell by replacing the evaporator core, condenser, drain pan, etc. However, this is rarely necessary as steps 2 and 3 usually take care of the problem.Having said all of this, step #1 is key - if you don't start shutting the A/C off (but leaving the fan on) a couple of minutes before you park your car, the mold, fungus, and/or bacteria will just come back stronger than ever.Written it depends a bit what you mean with bad, bad can be leaking liquids of which you don't like the smell, or it could mean a certain smell like in a humid bathroom which was not cleaned for some time which comes from funghi and other smells which arise where water and humidity is becoming foul ( rotting dirt ) then of course there is the possibility of rubber and plastic smells since one part of the cooling system gets rather

hot in the process. my guess is that you mean that smell of foul water.Written The most common source of bad smell and odour in your vehicle is the air conditioning system. This is because it is a small enclosed space that is constantly wet and moist. This gives rise to formation of mould, bacteria and fungus especially around the condenser and evaporator of the air conditioning unit. Apart from this, bad smell can also come from heated up rubber and plastic in the unit though this will be only when the AC is on for quite some time. Written If it is mold you want to be very careful trying to remove it yourself. Mold can be very dangerous when inhaled so you want to take the right precautions. In most cases you want to hire professional to ensure all the mold is removed.Show All ItemsWith summer approaching soon comes the time to turn on the AC to keep the house cold. You might notice that your electric bill spikes up more than expected or that your house is just having trouble staying cold.
