Things To Check When Your Air Conditioner Will Not Turn On

This article discusses a few AC troubleshooting tips that should come in handy if ever your cooling system doesn’t run the way you expect it to.

Air Conditioner Power Source

Always start from the source. If your air conditioner doesn’t turn on when you are desperate to escape the heat, then you might panic and fail to look at the most obvious issues. Do not skip the basics, such as the power supply.

First, look at the breaker to see if electricity has been cut off for whatever reason. Find the main electrical panel to check whether the breaker for the air conditioner was tripped. If it is in the off position, then just flip it back on to normalize the situation.

Don’t take anything for granted. Trace the electrical plug and see whether this has been inserted properly into a wall socket. Try to wiggle it to test if it is securely attached.

Don’t forget the thermostat, which controls the AC. Sometimes people think that their cooling system isn’t working, but the reality is that it is the thermostat that is causing the system to behave that way. See if the device is receiving power. Double-check the settings.

We often overlook the basics thinking that they are probably not worth the time, yet these things could be the key to a quick fix. Never rule anything out when troubleshooting.

Improve Familiarity with the Air Conditioner & Its Switches

Get familiar with the cooling system and its components. Anyone can learn how to overcome common concerns if they understand how the HVAC unit works. The secret to a long service life for an air conditioner is regular HVAC maintenance work. Check the manufacturer’s instructions about this matter.

Get to know the switches on the AC. Find out where the on/off switch is located on the indoor air handler. If this power switch is in the off position, then simply flick this on. You may also find an emergency shut-off switch near the outdoor unit. If someone turned this off by accident, then walk over and turn it back on.

Check the Air Filter

Every air conditioner troubleshooting guide will remind homeowners to check their air filters. These are passive dirt blockers that need replacement every 30-90 days, depending on the level of pollutants in the surroundings. Regular replacement ensures effective filtration while allowing adequate airflow through the system.

Filters are needed to maintain a high indoor air quality which protects the health of the family. Blocking dirt and dust, these filters also keep the system’s interior in good shape for longer.

Filters that are left on the system for too long develop a thick layer of dirt on their surfaces. These can prevent air from getting inside, forcing the air conditioner to work harder and consume more energy to produce the same amount of cooling. The reduced efficiency leads to soaring energy bills. It can also cause system failure.

Monitor your air filters. Perform a monthly check to assess their condition. Follow a periodic replacement schedule that is easy to remember. Set a calendar reminder if you need to. Never let them reach a point where clogs interfere with HVAC airflow.

Excessive energy consumption by the air conditioner is not just a problem of costly utility bills. It is also an indicator that the system is working much harder than it should, thus stressing the components. This hastens wear and tear, making breakdowns occur early than usual. This may force owners to replace the air conditioner within just a few years instead of enjoying its services for over a decade. Replace the filters as scheduled to avoid this.

Check the Drain Pan

When discussing the air conditioning unit with a technician, ask for tips about cleaning the drain pan. This holds all the moisture from condensation inside the system. If this gets full, a float switch will automatically bar the unit from turning on.

Remember that air conditioners trigger condensation naturally around the cold coils. The water should immediately flow out through the drain line. However, clogs along the path can keep the moisture in.

If you can empty the pan and unclog the line, the unit should return to normal. Those who are not sure how to do this may seek the help of an HVAC professional.

Check the Evaporator Coils

Certain components are sensitive to dirt and dust, including the evaporator coils. Keep the coils as clean as possible to prolong system life.

Just as you need to replace the filters on a regular basis, you also need to clean the coils with consistency. You can drastically decrease the risk of damage with this habit. That’s because dirty coils prevent heat transfer, such that the system is unable to function well. Clean this at least once every year via an air conditioner tune-up.

Discuss coil cleaning with your trusted HVAC contractor. Ask them to perform system tune-up annually to maintain peak performance and efficiency. Try to finish this in the spring so that you can be ready for summer.

Last Words

Do not panic if your air conditioner refuses to turn on. The problem could be as simple as a loose plug or a disconnected power source. It could also be a symptom of neglect, reminding you to clean the coils and replace the filters. These are tasks that anyone can do with a bit of guidance. Refer to the user’s manual for instructions. If the problem persists, then it is time to call the professionals for intensive troubleshooting. You should also schedule professional maintenance every year.
