Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a few explanations why your central AC system won’t work: a blown circuit breaker, inaccurate thermostat settings, a shut off switch or a full condensate drain pan.

Blown Circuit Breaker

Your AC won’t run when you have a tripped breaker.

To find out if one has blown, find your home’s main electrical panel. You can locate this metallic fixture on the wall in the basement, garage or closet.

  • Ensure your hands and feet are dry before you check the panel or breakers.
  • Find the breaker identified “AC” and ensure it’s in the “on” position. If it’s overloaded, the switch will be in the "off" position.
  • Steadily transfer the switch back to the “on” position. If it immediately flips again, don’t reset it and contact us at 601-292-9763. A breaker that keeps flipping might signal your house has electrical trouble.

If your thermostat isn’t giving a sign to your AC to work, it won’t switch on.

The most important part is checking it’s on “cool” and not “heat.” Otherwise your AC might not turn on. You may also receive hot air blowing from vents since the furnace is running instead.

If you have a regular thermostat:

  • Replace the batteries if the screen is empty. If the monitor is showing scrambled letters, buy a new thermostat.
  • Check the correct setting is on the display. If you can’t update it, cancel it by decreasing the temperature and hitting the “hold” button. This will force your AC to work if programming is incorrect.
  • Attempt to set the thermostat 5 degrees lower than the space’s temperature. Your AC won’t cool if the thermostat is set the same as the room’s temperature.

Once your thermostat is adjusted accurately, you should start getting refreshing air fast.

If you rely on a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for troubleshooting. If you’re still having problems, reach us at 601-292-9763 for assistance.

switch icon Turn-Off Switch

Your air conditioner typically has a shut-off device near its outdoor unit. This switch is generally in a metal box hung on your residence. If your equipment has recently been fixed, the switch may have accidentally been turned off.

Blocked Condensate Drain Pan drain pan icon

Condensate drain pans catch the additional water your system takes out of the air. This pan can be found either under or within your furnace or air handler.

When there’s a clog or clogged drain, water can build up and prompt a safety control to switch off your air conditioner.

If your pan involves a PVC pipe or drain, you can clear the extra water with a special pan-cleaning tab. You can get these tabs at a home improvement or hardware retailer.

If your pan involves a pump, look for the float switch. If the switch is “up” and there’s water in the pan, you might have to get a new pump. Contact us at 601-292-9763 for support.

2. AC Blows Warm Air

If your AC is working but not delivering cold air, its airflow might be obstructed. Or it could not have adequate refrigerant.

Clogged Airflow

Your equipment’s airflow can be decreased by a clogged air filter or filthy condenser.

How to Change Your Air Filter

A filthy filter can lead to a lot of troubles, such as:

  • Limited airflow
  • Icy refrigerant lines or evaporator coil
  • Intermittent cooling
  • Higher utility expenses
  • Making your system stop working sooner

We suggest replacing flat filters every four weeks, and pleated filters every three months.

If you can’t recall when you last replaced your filter, switch off your AC completely and pull out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It might also be found in a connected filter case or wall-mounted return air grille.

Tilt the filter up to the sunshine. If you can’t see any light, you need to buy a new filter.

4 Steps to Cleaning Your Air Conditioning System

Greenery, grass and bushes can block your condensing unit. This can limit its airflow, impact its energy efficiency and impact your comfort. Here’s a method you can follow to get your unit operating properly again.

  1. Switch off electricity fully at the breaker or outside lever.
  2. Get rid of yard waste around the air conditioner. Once you’ve removed bigger debris within a two-foot radius, you can use a soft brush or vacuum to slowly clean the condenser fins. Distorted fins can also hurt performance.
  3. Use a hose nozzle to gingerly clean the fins from inside the system. Make sure to avoid getting moisture on the fan motor.
  4. Turn the power back on.
refrigerant icon

Insufficient Refrigerant

When air conditioning equipment doesn’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your residence.

Here are a few indications that your equipment is seeping refrigerant:

  1. It takes a long time to cool your rooms and you’re regularly turning down the thermostat.
  2. Air conditioning moving through the vents isn’t as chilled as it should be.
  3. You’re noticing hissing or burbling sounds when the air conditioning is on.
  4. Your evaporator coil is iced over due to having difficulty absorbing humidity.

Think your system is leaking refrigerant? You need a certified heating and cooling service professional to take care of the leak and refill the right measurement of refrigerant in your equipment. Get in touch with us at 601-292-9763 for help.

3. AC Not Blowing Enough Air

When it feels like you’re not having ample amounts of chilled air, there’s usually an obstruction or disconnection within your AC system.

  • The first step is looking at your air filter. Get a new one if it’s soiled.
  • Make sure the vents are open across your home.
  • If you’re still not getting enough chilled air, you should have your ductwork inspected by a specialist like Oak Grove Heating & Air Conditioning. Your duct system may need to be fixed or rejoined in difficult spots like your attic, basement or crawl space.
