Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be several reasons why your air conditioning system won’t run: a blown circuit breaker, inaccurate thermostat settings, a turned off switch or an overflowing condensate drain pan.

Overloaded Circuit Breaker

Your AC won’t work when you have an overloaded breaker.

To find out if one has gotten overloaded, find your house’s main electrical panel. You can spot this gray device 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 marked “AC” and make sure it’s in the “on” spot. If it’s triggered the lever will be in the middle of the panel or “off” location.
  • Quickly shift the breaker back to the “on” location. If it immediately trips again, don’t touch it and call us at 812-663-7252. A fuse that keeps tripping could indicate your house has an electrical issue.

Incorrect Thermostat Settings

If your thermostat isn’t signaling your air conditioner to run, it won’t switch on.

The most important step is ensuring it’s on “cool” and not “heat.” Otherwise your air conditioner might not turn on. Or you may have. warm air moving from vents because the heater is going instead.

If you’re using a regular thermostat:

  • Replace the batteries if the monitor is empty. If the readout is displaying jumbled numbers, replace the thermostat.
  • Ensure the proper mode is showing. If you can’t update it, reverse it by dropping the temperature and pushing the “hold” button. This will force your AC to work if the configuration is wrong.
  • Attempt to set the thermostat 5 degrees below the room’s temperature. Your AC won’t start if the thermostat is set the same as the room’s temperature.

Once your thermostat is set accurately, you should start getting cold air promptly.

If you’re using a smart thermostat, such as one produced by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for help. If it still won’t work, reach us at 812-663-7252 for support.

Turn-Off Switch

Your cooling equipment probably has a shut-off switch by its condenser. This lever is generally in a metal box attached to your house. If your equipment has recently been maintained, the switch may have accidentally been put in the “off” location.

Clogged Condensate Drain Pan

Condensate drain pans catch the additional liquid your system removes from the air. This pan can be positioned either under or within your furnace or air handler.

When there’s a blockage or blocked drain, water can become concentrated and trigger a safety feature to switch off your equipment.

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

If your pan includes a pump, locate the float switch. If the mechanism is “up” and there’s water in the pan, you could need to replace the pump. Reach us at 812-663-7252 for support.

2. AC Blows Warm Air

If your AC is on but not cooling, its airflow could be clogged. Or it could not have enough refrigerant.

Obstructed Airflow

Your unit’s airflow can be decreased by a clogged air filter or dusty condenser.

How to Put in a New Your Air Filter

A dirty filter can lead to many problems, like:

  • Lower airflow
  • Icy refrigerant lines or evaporator coil
  • Intermittent cooling
  • Bigger electricity costs
  • Making your system wear out faster

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

If you aren’t sure when you last installed a new one, shut off your AC fully and pull out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be found in an attached filter box or wall-mounted return air grille.

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

How to Clean Your Cooling System

Brush, vegetation and leaves can block your condensing unit. This may reduce its airflow, impact its energy efficiency and change your comfort. Here’s how you can get your equipment working smoothly again.

  1. Switch off electricity totally at the breaker or outdoor lever.
  2. Clear vegetation rubbish around the air conditioner. Once you’ve cleared larger clutter within a two-foot range, you can use a fine-bristled brush or vacuum to slowly remove dirt from the condenser fins. Crooked fins can also affect performance, so you can attempt to adjust them with a small knife.
  3. Use a hose nozzle to gingerly take off dirt on the fins from inside the unit. Make sure to avoid getting liquid on the fan motor.
  4. Put the top back on and restore the power.

Low Refrigerant Levels

When air conditioning systems don’t have sufficient refrigerant, they’ll struggle to remove heat and humidity from your residence.

Here are several symptoms that your system is leaking refrigerant:

  1. It takes a long time to cool your house and you’re continually decreasing the temperature on the thermostat.
  2. Air conditioning moving through the registers isn’t as cold as it should be.
  3. You’re hearing fizzing or gurgling sounds when the AC runs.
  4. Your evaporator coil is iced over because it’s having trouble taking on warmth.

Think your system is leaking refrigerant? You need a certified heating and cooling service specialist to take care of the leak and restore the right level of refrigerant in your unit. Get in touch with us at 812-663-7252 for assistance.

3. AC Not Blowing Enough Air

When it feels like you’re not getting enough cold air, there’s potentially an obstruction or separation within your air conditioning unit.

  • The beginning place is looking at your air filter. Replace it if it’s filthy.
  • Then make sure the vents are free throughout your residence.
  • If you’re still not receiving enough chilly air, you should have your ductwork inspected by a professional like Wallpe Heating & Cooling. Your ducts might need to be fixed or reconnected in hard-to-reach spots like your attic, basement or crawl space.
