AC power cord has come unplugged from the outlet or air handler

Air conditioners can be plugged into an outlet or air handler in a variety of ways. If the AC power cord has come unplugged from the outlet or air handler, the air conditioner may not work.

If the AC power cord has come unplugged from the outlet or air handler, make sure to plug it back in. If the AC power cord is plugged in and the air conditioner still doesn’t work, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


The air conditioner is too cold.


Air conditioners can be too cold for comfort, leaving you feeling chilly and uncomfortable.

If your air conditioner is too cold, the first thing to check is the thermostat setting. Make sure the thermostat is set to the correct temperature for your location and season of the year. If the thermostat is set correctly but your air conditioner is still too cold, there may be a problem with the unit itself that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


The air conditioner doesn’t work at all.


Air conditioners can stop working for a variety of reasons, including a blown fuse, a tripped circuit breaker, or a problem with the compressor.

If your air conditioner doesn’t work, the first thing to check is to make sure it’s plugged in and that the circuit breaker hasn’t been tripped. If it is plugged in and the breaker hasn’t been tripped, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


The air conditioner leaks water or sprays water from the vents


Air conditioners can leak water for a variety of reasons, including a clogged drainage pipe or a problem with the compressor.

If your air conditioner is leaking water, the first thing to check is the drainage pipe to make sure it’s not clogged. If the drainage pipe is clear, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


The air conditioner smells bad


Air conditioners can smell bad for a variety of reasons, including a dirty filter, bacteria growth, or a problem with the compressor.

If your air conditioner smells bad, the first thing to check is the filter. Air filters should be replaced every month, and if they’re not dirty they can be reused. If the filter is clean and the air conditioner still smells bad, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


The air conditioning unit is noisy and rattles loudly when it turns on


Air conditioning units can be noisy for a variety of reasons, including a dirty filter, a problem with the compressor, or loose screws.

If your air conditioning unit is noisy, the first thing to check is the filter. Air filters should be replaced every month, and if they’re not dirty they can be reused. The second thing you should check for is loose screws. Make sure to check all loose screws and tighten if need be. If the filter is clean and all screws are tightened and the air conditioner still makes noise, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


The air conditioning unit won’t turn off completely, even after the thermostat says to shut down


Air conditioning units can continue to run even after the thermostat says it’s time to shut down. This is usually caused by a problem with the compressor or another component of the air conditioner.

If your air conditioning unit won’t turn off, the first thing to check is the thermostat. Make sure the thermostat is set to the “off” position. If the thermostat is set correctly and the air conditioner still won’t turn off, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


Thermostat settings are wrong; set them correctly for your location and season of the year


Air conditioners are designed to maintain a certain temperature in your home. If the thermostat is set too low or too high, the air conditioner may not work correctly.

If you’re having problems with your air conditioner, make sure to check the thermostat settings and adjust them accordingly. The thermostat should be set to the correct temperature for your location and the season of the year. If the thermostat is set correctly and you’re still having problems, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.


Dirty filter – replace it with a new one once every month


if the filter is dirty it will slow down the air conditioning process and cause the unit to work harder than necessary. Air filters should be replaced every month, and if they’re not dirty they can be reused. Having a clean filter will help your air conditioner run more efficiently and save you money on your energy bill.


Blocked vent – clear any obstructions to allow airflow through the unit


Air conditioners need airflow to work correctly. If the vents are blocked, the air conditioning unit will not be able to cool your home properly.

If you’re having problems with your air conditioner, make sure to check the vents and clear any obstructions that may be blocking the airflow. If the vents are clear and the air conditioner still isn’t working correctly, there may be a problem with the compressor or another component of the air conditioner that needs to be fixed by a technician from Northeast Ohio HVAC LLC.
