Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a few explanations why your air conditioning system won’t work: a tripped circuit breaker, wrong thermostat settings, a switched off switch or an overfull condensate drain pan.

Overloaded Circuit Breaker

Your system won’t run when you have a blown breaker.

To see if one has blown, find your house’s main electrical panel. You can find this metallic device on the wall in the basement, garage or closet.

  • Confirm your hands and feet are dry before you touch the panel or breakers.
  • Look for the breaker marked “AC” and confirm it’s in the “on” position. If it’s triggered, the switch will be in the "off" position.
  • Steadily transfer the switch back to the “on” location. If it immediately flips again, don’t reset it and reach us at (985) 764-2426. A switch that keeps turning off may signal your residence has an electrical issue.

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

The most important part is making sure it’s switched to “cool” and not “heat.” Otherwise your air conditioner will probably not switch on. You might also receive hot air moving from vents being the heater is going instead.

If you rely on a regular thermostat:

  • Put in new batteries if the readout is empty. If the readout is presenting jumbled letters, replace the thermostat.
  • Check the proper mode is displaying. If you can’t update it, override it by dropping the temperature and hitting the “hold” button. This will make your AC start if scheduling is not right.
  • Attempt to set the thermostat 5 degrees cooler than the house’s temperature. Your AC won’t work if the thermostat is set the same as the house’s temperature.

Once your thermostat is calibrated accurately, you should receive cold air quickly.

If you’re using a smart thermostat, such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for assistance. If you’re still having problems, contact us at (985) 764-2426 for assistance.

switch icon Shut-Off Switch

Your system usually has a power-cutting lever around its condenser. This switch is commonly in a metal box mounted on your residence. If your equipment has recently been repaired, the device may have inadvertently been turned off.

Clogged Condensate Drain Pan drain pan icon

Condensate drain pans catch the additional condensation your AC takes out of the air. This pan is located either beneath or in your furnace or air handler.

When there’s a clog or blocked drain, water can become concentrated and prompt a safety setting to stop your unit.

If your pan has a PVC pipe or drain, you can drain the extra condensation with a formulated pan-cleaning tablet. You can get these capsules at a home improvement or hardware store.

If your pan includes a pump, locate the float switch. If the switch is “up” and there’s moisture in the pan, you could need to get a new pump. Call us at (985) 764-2426 for assistance.

2. AC Blows Warm Air

If your air conditioner is going but not delivering cold air, its airflow might be obstructed. Or it could not have enough refrigerant.

Clogged Airflow

Your system’s airflow can be limited by a blocked air filter or dirty condenser.

How to Put in a New Your Air Filter

A filthy filter can cause a lot of troubles, including:

  • Reduced airflow
  • Frozen refrigerant lines or evaporator coil
  • Inconsistent cooling
  • Increased utility bills
  • Making your system wear out more quickly

We propose changing flat filters every four weeks, and pleated filters every three months.

If you aren’t sure when you last replaced your filter, switch off your equipment totally and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It might also be found in an adjoining filter box or wall-mounted return air grille.

Hold the filter up to the sunshine. If you see a lot of dust, you need to get a new one.

4 Tips on Cleaning Your Air Conditioning System

Brush, grass and shrubbery can get in the way of your condensing system. This could reduce its airflow, lower its energy efficiency and change your comfort. Here’s how you can get your equipment working properly again.

  1. Switch off electricity completely at the breaker or outside switch.
  2. Remove yard rubbish around the air conditioner. Once you’ve gotten rid of larger clutter within a two-foot range, you can use a soft brush or vacuum to carefully remove dirt from the condenser fins. Deformed fins can also affect efficiency.
  3. Use a hose nozzle to carefully clean the fins from inside the system. Make sure to avoid getting liquid on the fan motor.
  4. Turn the power back on.

Insufficient Refrigerant

When air conditioning systems don’t have sufficient refrigerant, they’ll have to work much harder to remove heat and humidity from your home.

Here are a couple of signs that your system is losing refrigerant:

  1. It takes too long to lower the temperature in your home and you’re regularly decreasing the temperature on the thermostat.
  2. Air conditioning moving through the ducts isn’t as cold as it should be.
  3. You’re hearing whistling or bubbling sounds when cooling works.
  4. Your evaporator coil is icy as a result of having trouble handling humidity.

Worried your unit is leaking refrigerant? You need a licensed heating and cooling service specialist to take care of the leak and refill the correct level of refrigerant in your system. Get in touch with us at (985) 764-2426 for support.

3. AC Not Blowing Enough Air

When it seems like you’re not getting adequate amounts of chilled air, there’s likely a blockage or separation somewhere in your cooling system.

  • The beginning step is checking your air filter. Replace it if it’s dirty.
  • Make sure the vents are open around your home.
  • If you’re still not experiencing sufficient chilly air, you should have your ductwork checked by a pro like Mayeuxs AC & Heating. Your duct system might need to be repaired or reconnected in hard-to-reach areas like your attic, basement or crawl space.
