Air Conditioner Repair Checklist

1. AC Won’t Turn On

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

Tripped Circuit Breaker

Your cooling won’t start when you have a tripped breaker.

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

  • Confirm your hands and feet aren’t wet before you work on the panel or breakers.
  • Locate the breaker identified “AC” and make sure it’s in the “on” location. If it’s triggered the breaker will be in the in between or “off” spot.
  • Firmly move the lever back to the “on” position. If it instantly triggers again, don’t reset it and get in touch with us at 812-825-8695. A fuse that keeps flipping could mean your home has an electrical issue.

Incorrect Thermostat Settings

If your thermostat isn’t telling your system to run, it won’t activate.

The key step is ensuring it’s switched to “cool” and not “heat.” Otherwise your AC might not turn on. Or you might receive. heated air moving from vents since the furnace is running instead.

If you’re using a digital thermostat:

  • Put in new batteries if the monitor is empty. If the monitor is displaying scrambled numbers, get a new thermostat.
  • Ensure the correct mode is displaying. If you can’t change it, reverse it by lowering the temperature and pushing the “hold” button. This will cause your AC to run if scheduling is wrong.
  • Test setting the thermostat 5 degrees colder than the house’s temperature. Your AC won’t start if the thermostat matches the house’s temperature.

Once your thermostat is calibrated properly, you should start getting cool air fast.

If you rely on a smart thermostat, like one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for assistance. If you still can’t get it to work, call us at 812-825-8695 for assistance.

Shut-Down Switch

Your system probably has a shut-down lever near its condenser. This switch is typically in a metal box mounted on your residence. If your equipment has recently been maintained, the lever may have accidentally been placed in the “off” position.

Clogged Condensate Drain Pan

Condensate drain pans keep the surplus liquid your air conditioner takes out of the air. This pan can be situated either beneath or within your furnace or air handler.

When there’s an obstruction or clogged drain, water can become concentrated and initiate a safety setting to switch off your system.

If your pan has a PVC pipe or drain, you can clear the extra liquid with a formulated pan-cleaning capsule. You can buy these tabs at a home improvement or hardware store.

If your pan has a pump, look for the float switch. If the mechanism is “up” and there’s moisture in the pan, you could need to get a new pump. Reach us at 812-825-8695 for help.

2. AC Blows Warm Air

If your equipment is working but not delivering cold air, its airflow may be blocked. Or it could not have enough refrigerant.

Obstructed Airflow

Your equipment’s airflow can be reduced by a clogged air filter or dusty condenser.

How to Replace Your Air Filter

A dusty filter can cause many problems, like:

  • Lower cooling
  • Icy refrigerant lines or evaporator coil
  • Uneven cooling
  • Bigger electricity bills
  • Leading your system to break down more quickly

We recommend installing new flat filters once a month, and pleated filters every three months.

If you can’t remember when you last changed yours, switch off your AC totally and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It might also be located in a connected filter case or wall-mounted return air grille.

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

4 Steps to Cleaning Your Cooling Unit

Brush, grass and shrubbery can get in the way of your condensing unit. This can limit its airflow, make it less energy efficient and change your comfort. Here’s a method you can follow to get your unit running well again.

  1. Turn off power fully at the breaker or outside lever.
  2. Get rid of plant rubbish around the air conditioner. Once you’ve cleared bigger clutter within a two-foot range, you can use a paint brush or vacuum to slowly clean the unit’s fins. Warped fins can also hurt efficiency, so you can attempt to correct them with a dinner knife.
  3. Use a hose nozzle to slowly remove gunk off the fins from inside the system. Be careful to avoid getting water on the fan motor.
  4. Put the top back on and restore the power.

Low Refrigerant Levels

When cooling equipment doesn’t have adequate refrigerant, they’ll have difficulty removing heat and humidity from your space.

Here are a few signs that your equipment is leaking refrigerant:

  1. It takes an extended amount of time to lower the temperature in your house and you’re continually lowering the thermostat.
  2. Cooling coming through the registers isn’t as cold as it should be.
  3. You’re experiencing whistling or gurgling noises when the air conditioning runs.
  4. Your evaporator coil is icy because it’s having trouble handling humidity.

Suspect your unit is losing refrigerant? You need a licensed heating and cooling service specialist to fix the leak and refill the proper amount of refrigerant in your unit. Call us at 812-825-8695 for help.

3. AC Not Blowing Enough Air

When it feels like you’re not receiving ample amounts of chilled air, there’s potentially an obstruction or disconnection somewhere in your cooling system.

  • The initial place is examining your air filter. Replace it if it’s dusty.
  • Then check the ductwork is open throughout your house.
  • If you’re still not experiencing sufficient chilled air, you should have your ductwork examined by a specialist like Stanford Heating & Cooling. Your ducts could need to be fixed or rejoined in tricky areas like your attic, basement or crawl space.
