Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a couple of reasons why your air conditioner won’t work: a triggered circuit breaker, inaccurate thermostat settings, a switched off switch or an overflowing condensate drain pan.

Triggered Circuit Breaker

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

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

  • Make sure your hands and feet are dry before you check the panel or breakers.
  • Find the breaker labeled “AC” and confirm it’s in the “on” position. If it’s triggered the lever will be in the middle of the panel or “off” location.
  • Firmly transfer the lever back to the “on” location. If it instantaneously trips again, don’t touch it and call us at (985) 764-2426. A fuse that keeps flipping may mean your house has an electrical issue.

Incorrect Thermostat Settings

If your thermostat isn’t telling your air conditioner to run, it won’t turn on.

The most important part is ensuring it’s on “cool” and not “heat.” Otherwise your AC might not switch on. Or you could get. hot air moving from vents because the heater is running instead.

If you have a regular thermostat:

  • Put in new batteries if the screen is empty. If the screen is displaying garbled letters, get a new thermostat.
  • Ensure the right option is on the display. If you can’t update it, override it by lowering the temperature and pushing the “hold” button. This will force your AC to work if programming is not right.
  • Try setting the thermostat 5 degrees lower than the house’s temperature. Your AC won’t cool if the thermostat is set the same as the room’s temperature.

Once your thermostat is set accurately, you should receive cool air quickly.

If you’re using a smart thermostat, like one made by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for assistance. If it still won’t work, reach us at (985) 764-2426 for support.

Shut-Off Switch

Your cooling equipment usually has a shut-down switch near its outdoor unit. This lever is generally in a metal box mounted on your home. If your AC has recently been maintained, the lever may have unintentionally been placed in the “off” position.

Clogged Condensate Drain Pan

Condensate drain pans keep the additional liquid your equipment removes from the air. This pan can be situated either beneath or in your furnace or air handler.

When there’s a clog or backed up drain, water can become concentrated and initiate a safety feature to switch off your unit.

If your pan involves a PVC pipe or drain, you can clear the surplus condensation with a formulated pan-cleaning tablet. You can buy these capsules at a home improvement or hardware retailer.

If your pan involves a pump, look for the float switch. If the mechanism is “up” and there’s water in the pan, you may need to replace the pump. Call us at (985) 764-2426 for support.

2. AC Blows Warm Air

If your air conditioner is working but not providing cold air, its airflow might be clogged. Or it might not have sufficient refrigerant.

Obstructed Airflow

Your system’s airflow can be reduced by a plugged air filter or dirty condenser.

How to Change Your Air Filter

A dirty filter can lead to numerous issues, such as:

  • Lower cooling
  • Frozen refrigerant lines or evaporator coil
  • Uneven cooling
  • Increased electricity costs
  • Causing your system to break down faster

We propose changing flat filters monthly, and creased filters every three months.

If you can’t recall when you last installed a new one, shut off your equipment fully and take out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It might also be found in an attached filter case or wall-mounted return air grille.

Hold the filter up to your light fixture. If you see a lot of dust you should get a new one.

How to Clean Your Air Conditioning Unit

Brush, plants and bushes can obstruct your condensing equipment. This may reduce its airflow, impact its energy efficiency and affect your comfort. Here’s a method you can follow to get your equipment running smoothly again.

  1. Turn off power fully at the breaker or outside device.
  2. Remove vegetation waste around the AC. Once you’ve cleared all the refuse within a two-foot area, you can use a soft brush or vacuum to slowly clean the condenser fins. Misshapen fins can also affect performance, so you can attempt to reshape them with a dinner knife.
  3. Use a hose nozzle to slowly remove gunk off the fins from inside the equipment. Don’t get moisture on the fan motor.
  4. Replace the top and turn the power back on.

Not Enough Refrigerant

When cooling equipment doesn’t have ample refrigerant, they’ll have to work much harder to remove heat and humidity from your home.

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

  1. It takes an extended amount of time to refresh your space and you’re constantly decreasing the temperature on the thermostat.
  2. Air blowing through the registers isn’t as chilly as it should be.
  3. You’re hearing hissing or gurgling noises when cooling is on.
  4. Your evaporator coil is icy because it’s having an issue taking on heat.

Suspect your equipment is losing refrigerant? You need a licensed heating and cooling service expert to fix the leak and replenish the right measurement of refrigerant in your system. Call us at (985) 764-2426 for assistance.

3. AC Not Blowing Enough Air

When it feels like you’re not receiving ample amounts of cool air, there’s potentially an obstruction or separation inside your cooling equipment.

  • The beginning stage is checking your air filter. Buy a new one if it’s dusty.
  • Then ensure the vents are clear across your home.
  • If you’re still not getting ample cold air, you should have your duct system inspected by a professional like Mayeuxs AC & Heating. Your ducts might need to be fixed or rejoined in limited space spots like your attic, basement or crawl space.
