what are the causes of ac failure air conditioner manufacturers generally make rugged, high quality products that last for years. If your air conditioner fails, begin by checking any fuses or circuit breakers. Let the unit cool down for about five minutes before resetting any breakers.
CAUSES OF AN AIR CONDITIONER FAILURE YOU NEED TO KNOW ABOUT
1.A faulty thermostat
This is another component that if it fails on its own means trouble. The thermostat is what informs the air conditioner when to turn on and off in order to keep your home at your desired temperature. However, it’s possible for a thermostat to get out of calibration or break, which will cause the temperature in your home to fluctuate.
That’s why if your air conditioner is failing, be sure to check the thermostat first and make sure it’s reading the temperature properly. If it is, then the issue lies with another component connected to it. Again, this task is best left to a technician to diagnose and treat since there are several underlying causes of a faulty thermostat.
2. LOW REFRIGERANT. The refrigerant is the stuff that your air conditioner uses to remove the heat and humidity from the air in your home or business. If your system develops leaks in the refrigerant lines, you can end up with not enough refrigerant to effectively cool the air. Unfortunately, fixing this air conditioner problem correctly is not just a matter of replacing the refrigerant.
3. FROZEN EVAPORATOR COILS. Your air conditioner’s evaporator coil is filled with refrigerant, and is responsible for absorbing the heat from the air like a sponge. It may sound counter-intuitive, but those coils need warm air circulating around them to work properly. When something goes wrong with the airflow and the evaporator coil gets too cold, a layer of ice can build up on the outside.
Easy steps to prevent air conditioner problems:
1. REPLACE DIRTY AIR FILTERS. Air flow problems that lead to coils freezing are often caused by clogged air filters.
2. INSPECT DUCTS AND REPAIR ANY HOLES. If it seems like there’s not enough air coming from the registers, or your energy bills keep going up, have an HVAC expert take a look at the condition of your ducts.
3. INSTALL A PROGRAMMABLE THERMOSTAT AND LEARN HOW TO USE IT. Eliminate issues with older control systems by installing new thermostats, which are more precise and save energy.
