If you've dealt with the Montana heat before, you understand that an inconsistent air conditioner can be a problem. If you've been wondering, "Why does my air conditioner turn off by itself?" turn to Premier Systems, a leading HVAC specialist in Bozeman, MT. We'll explain everything you need to know about why your air conditioner unit may stop running, the signs of air conditioner failure, and what you can do to get your temperature control back to normal in your Bozeman home.


WHY DOES MY AIR CONDITIONER TURN OFF BY ITSELF? SIX AC UNIT PROBLEMS TO CONSIDER IN Bozeman, MT


If you're having issues with the air conditioner, one of the first symptoms you'll likely notice is how often it shuts down. When your air conditioner works harder to cool off a room, it may be subject to short cycling. This means that an air conditioner will run for only a short time, attempting to cool off a room before it shuts down because it thinks the room is sufficiently cold.


There are many reasons your air conditioner may short cycle, many of which are due to natural wear and tear on your machine; these unit problems include the following.


1. Busted Thermostat


Think of your thermostat as the brains behind your entire HVAC system. If your thermostat can't function due to some electrical problems, then neither can your air conditioner unit. If you ask yourself, "Why does my air conditioner turn off by itself?" often, then this may be one of the problems you'll face for your unit.


2. Clogged Air Filter


Another reason you may have a short cycling air conditioner is because the air filter requires maintenance. Air filters, when full of dust and dirt, become like insulated padding for your air conditioner, which isn't a good thing. This inadvertent padding becomes a burden to the entire unit, making everything warmer and lessening the effectiveness of the air conditioner's natural functions. In addition, it puts undue strain on every component inside. 


3. Incorrect Thermostat


Because the thermostat thinks for your HVAC system, one set to a sub-optimal setting can mislead an air conditioner into short cycling. For example, if you have your thermostat set to Energy Saving Mode or a specific temperature, it may not automatically cool your rooms like you want it to. Before trying to diagnose anything, check your thermostat thoroughly. 


4. Faulty Compressor


One of the most expensive and essential items in your air conditioner is, by far, your compressor. Without a functioning compressor, your air conditioner becomes a glorified fan, unable to cool the air that passes through it. The only way to fix a compressor is to consult a professional who can recommend an efficient air conditioner for your home size.


5. Malfunctioning Sensors


Another issue you may want to watch for involves the sensitive parts of your air conditioner, which includes everything from the circuit boards to the temperature sensors. If your sensors are out of sorts, you can't expect your air conditioner to function normally. If you find yourself asking, "Why does my air conditioner turn off by itself?" often, then the sensors may be triggering the on and off functions too frequently.


6. Refrigerant Issues


If you have a leak in addition to functionality problems with your air conditioner, you likely have a refrigerant issue. Refrigerant can leak or get low; both problems cause an ineffective air conditioner. If you have low refrigerant, though, don't worry; a quick appointment with an HVAC professional can have the exact issue diagnosed so you can have your cool air back.
