An air conditioning unit is no longer a luxury but a necessity. It has become such a significant appliance in every household that it becomes hard for people to cope when it breaks down. Even though getting a technician to repair it is not that hard, waiting for them to come to your home and fix it is no fun. When possible, it is better to know what can make your AC break down and avoid those problems. Here are some of the reasons your AC is not working.
Dead Thermostat Batteries
On most occasions, there is nothing wrong with the air conditioner. If the thermostat is not displaying anything, the batteries are probably out of juice. The solution is quite simple; switch them out. When the screen goes blank, and you have no idea why it has happened, checking the thermostat batteries should be the first thing you do.
Clogged Air Ducts
Air ducts need to be cleaned from time to time to enhance the proper circulation of air. Otherwise, you will just be dealing with poor air quality, leading to respiratory issues like coughing and sneezing. As warned by Murfreesboro Air Duct Cleaning, if you do not remove the dirt and debris clogging the duct, your energy bills are likely to hit the roof. This is because the AC works twice as much to keep you warm or cool.
The Indoor/Outdoor Disconnect Switch is Off
In most cases, this is usually turned off by accident by someone who was doing some work in your home. Before calling A HVAC technician to let them know that your system is not working, check that the units are connected to a power source.
Wrong Thermostat Settings
Ensure that you have set your thermostat in the correct settings. First, ensure that the thermostat has not accidentally switched from HEAT to COOL. Then check that the fan is on the proper setting. Setting the thermostat to ‘ON’ will make the fan run continuously and circulate air through the entire house and cause air to blow from the air vents even when the AC unit is not cooling the air. This means that air coming from the vents is the same temperature as the air in your home. An auto setting causes the fan to turn ON only during your AC cycles. When the cycle is over, the fan turns off again.
Dirty Evaporator Coil
The process of cooling air in the AC system happens along the surface and fins of the evaporator coil. When the evaporator coil is covered in dirt and dust, the cooling efficiency of the unit decreases. The accumulated dirt makes it difficult for coils to cool air to the right temperature, causing them not to work correctly.
If the AC is low on refrigerant, the AC struggles to cool the air inside your home. If there is a bubbling noise or hissing when the AC is operating, get a technician to fix the issue immediately.
Some issues like replacing batteries and changing the thermostat settings are pretty basic, and you can manage them yourself. However, in technical matters like a system with low refrigerant, get a skilled technician to handle it. In no time, your AC will be up and running efficiently.
