10 Reasons Your Air Conditioner Isn’t Working

As summer approaches, you need your central AC unit to be in good working order, and even the best air conditioners can malfunction over time. Have you noticed that your air conditioner is not cooling? Getting your air conditioner running smoothly again can be achieved with the help of the experts of AC replacement in Summerville, All Star Heating & Air. Before that, you should know the most common reasons for air conditioner failures.

10 AC Repair Tips You Need to Know Before Summer

1. Dead Thermostat Batteries

In some cases, there may be nothing wrong with the air conditioning unit itself. Your thermostat’s batteries are likely dead if it does not display anything. The first thing you should do when the screen on your thermostat is black is to change the batteries.

2. Tripped Circuit Breaker

You should check your breaker box when your air conditioner isn’t working. Overloaded circuits cause breakers to trip. If it trips again after you reset it, try shutting off other equipment that may be contributing to the problem. When all else fails, the best option is to contact our HVAC professional to diagnose the problem or for AC Replacement in Summerville.

3. Outdoor Disconnect Switch is off

There is indeed another disconnect switch. Building codes require switches to be installed next to your air conditioner’s indoor and outdoor units. There may have been several reasons why the outdoor switch was off, but luckily for you, it is very easy to reset.

4. Indoor Disconnect Switch is off

The disconnect switch also has a very simple fix: it needs to be turned off. Someone or something may have bumped the AC unit and shut off the disconnect switch, depending on where it is located in your home. If this problem persists, turn the disconnect switch on before taking further steps.

5. Circuit Breaker

A power surge can trip a breaker if you do laundry, use the dishwasher, and blast your AC simultaneously. If it is beyond repair, contact our professional to perform AC Replacement in Summerville.

6. Dirty Coils

Dirt buildup on the coils will eventually reduce your system’s ability to remove heat from your home. The same air will continuously circulate no matter what temperature the thermostat sets.

7. Refrigerant Leak

The air within your air conditioning unit is cooled by refrigerant. While it does its job well, it can be poisonous if it leaks from your AC system. Get in touch with our expert for AC installation in Summerville, SC.

8. Dirty Filter

A dirty filter has not been changed or cleaned regularly. Your air conditioner’s filters accumulate so much dust and gunk over time that they restrict airflow. The unit can freeze up without proper airflow, causing ice to form on the coils. In turn, this will affect how efficiently your air conditioner cools.

9. The Fan Motor Stopped Working

In the condenser unit, there is a motor that drives the fan. An air conditioner can malfunction if it does not receive regular maintenance or is approaching 15 to 20 years old.

10. Blown Fuse

Similarly to circuit breakers, a fuse will shut off if too much electrical current flows through it.
