What To Do When Your Air Conditioner Won’t Turn On Lumberton NJ

When your air conditioner breaks down, be sure to take the following steps to identify what the problem might be:

Step 1: Check The Settings On Your Thermostat

One of the most probable reasons why an air conditioner will not turn on is a faulty thermostat. If the thermostat has a problem, it will not be able to turn your AC on when temperatures rise beyond the set point. When your air conditioner doesn’t turn on, be sure to check the thermostat setting. If it is too high, turn the temperature down to see if the unit will turn on. If it does not, the thermostat may be faulty. However, you should continue with the troubleshooting process before you call for HVAC repairs or replacement.

Step 2: Inspect Your Home’s Circuit Breaker

There is also a breaker for appliances, such as the stove and water heater. There is also a breaker for low energy sockets. Your air conditioner also has a dedicated breaker. If your air conditioner won’t turn on, be sure to check the breaker to ensure it has not been tripped. If it has been tripped, your air conditioner will not be able to get power. Just reset it to turn on the AC.

Step 3: Check The Drain Pan

Every air conditioner has a drain pan and drains to take the condensate away from the air handler. If the drains are blocked by debris, the pan will overflow with condensate. This will trigger the float switch to turn the AC unit off. This is usually meant to stop the AC unit from freezing. Try to locate the drain pan to see if it is flooding before calling an HVAC contractor to resolve the problem. The technicians at McAllister Energy can deal with the problem effectively.

Step 4: Take A Look At The Shut-Off Switch

Power outlets usually have a shut-off switch. Since there are several people in your household, one of them might have accidentally turned off the AC from the shut-off switch. By checking the position of the knob at the shut-off switch, you can determine whether or not this is the problem. In case, the switch is in the off position, simply turn it on to start up the air conditioning system.

Step 5: Inspect The Fuse

A burned-out fuse can prevent the air conditioner from turning on. Fuses are designed to interrupt the circuit if there is an overload. If your AC was overloaded, the fuse might have been burned out. If this is the case, then you can replace it to restore the AC to its normal operating condition. The professionals at McAllister Energy can then inspect your system to determine the reason for the current overload to ensure the problem does not recur in the future.

Step 6: Check The HVAC Air Filter

HVAC air filterThere is always a chance that your AC may be running smoothly but there is no space-cooling taking place. This can be due to several things, such as lack of refrigerant in the system or a clogged air filter. If the air filter in your HVAC system is clogged, cooled air may not find its way into the room. In fact, this problem can lead to freezing of the air conditioner as the condensate freezing inside the air handler.

If cooled air is not able to move out of the AC unit, the low temperatures may force the moisture in air to condense and freeze. This usually leads to a frozen AC unit.

Regular cleaning and servicing of air conditioners can go a long way in preventing most of these problems. Be sure to call a competent HVAC firm, like McAllister Energy, to service your air conditioning system regularly. In addition to preventing frequent breakdowns, this will also boost energy efficiency and performance.
