Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be several explanations why your air conditioning won’t cool: a triggered circuit breaker, incorrect thermostat settings, a shut off switch or an overflowing condensate drain pan.

Blown Circuit Breaker

Your air conditioning won’t work when you have a blown breaker.

To find out if one has gotten overloaded, go to your home’s main electrical panel. You can spot this gray box on the wall in the basement, garage or closet.

  • Make sure your hands and feet are dry before you touch the panel or breakers.
  • Look for the breaker marked “AC” and make sure it’s in the “on” spot. If it’s overloaded the lever will be in the in between or “off” spot.
  • Firmly shift the lever back to the “on” location. If it instantly triggers again, leave it alone and contact us at 256-801-4701. A breaker that keeps tripping may mean your house has an electrical problem.

Incorrect Thermostat Settings

If your thermostat isn’t giving a sign to your system to start, it won’t activate.

The most important point is making sure it’s switched to “cool” and not “heat.” Otherwise your AC will probably not switch on. Or you could receive. hot air blowing from vents being the furnace is on instead.

If you have a regular thermostat:

  • Replace the batteries if the screen is blank. If the readout is presenting jumbled numbers, get a new thermostat.
  • Make sure the right program is showing. If you can’t change it, reverse it by dropping the temperature and pressing the “hold” button. This will force your AC to work if the configuration is incorrect.
  • Try setting the thermostat 5 degrees colder than the house’s temperature. Your AC won’t start if the thermostat is identical to the space’s temperature.

Once your thermostat is calibrated accurately, you should start getting cool air quickly.

If you have a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for help. If you still can’t get it to work, contact us at 256-801-4701 for support.

Shut-Off Switch

Your air conditioner typically has a shut-down switch by its outside unit. This switch is typically in a metal box mounted on your residence. If your AC has recently been worked on, the lever may have accidentally been placed in the “off” location.

Blocked Condensate Drain Pan

Condensate drain pans catch the extra water your AC removes from the air. This pan can be positioned either under or in your furnace or air handler.

When there’s a blockage or clogged drain, water can accumulate and trigger a safety control to turn off your unit.

If your pan involves a PVC pipe or drain, you can get rid of the extra liquid with a custom pan-cleaning tablet. You can purchase these capsules at a home improvement or hardware store.

If your pan has a pump, find the float switch. If the lever is “up” and there’s liquid in the pan, you may need to get a new pump. Call us at 256-801-4701 for assistance.

2. AC Blows Warm Air

If your equipment is going but not providing cold air, its airflow may be congested. Or it might not have adequate refrigerant.

Blocked Airflow

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

How to Put in a New Your Air Filter

A dirty filter can cause numerous problems, such as:

  • Reduced comfort
  • Frosted refrigerant lines or evaporator coil
  • Intermittent cooling
  • Higher utility costs
  • Leading your system to stop working sooner

We propose replacing flat filters monthly, and pleated filters every three months.

If you can’t remember when you last changed yours, switch off your equipment completely and remove the filter. You can spot the filter in your furnace or air pump’s blower compartment. It may also be situated in an attached filter box or wall-mounted return air grille.

Angle the filter up to the light. If you see a lot of dust you certainly should replace it.

How to Clean Your AC System

Brush, vegetation and sticks can obstruct your condensing equipment. This may limit its airflow, make it less energy efficient and affect your comfort. Here’s a method you can follow to get your equipment working properly again.

  1. Switch off power totally at the breaker or outdoor switch.
  2. Clear greenery waste around the air conditioner. Once you’ve cleared bigger debris within a two-foot range, you can use a soft brush or vacuum to slowly remove dirt from the condenser fins. Deformed fins can also impact capability, so you can attempt to straighten them with a blunt knife.
  3. Use a hose nozzle to slowly remove gunk off the fins from inside the unit. Make sure to avoid getting water on the fan motor.
  4. Replace the top and turn on the power.

Leaking Refrigerant

When AC systems don’t have ample refrigerant, they’ll have to work much harder to remove heat and humidity from your rooms.

Here are several symptoms that your equipment is losing refrigerant:

  1. It takes a long time to refresh your home and you’re regularly lowering the thermostat.
  2. Air coming through the ducts isn’t as chilled as it should be.
  3. You’re experiencing hissing or gurgling racket when the air conditioning runs.
  4. Your evaporator coil is frozen due to having an issue handling heat.

Suspect your equipment is seeping refrigerant? You need a qualified heating and cooling service professional to take care of the leak and restore the proper measurement of refrigerant in your equipment. Contact us at 256-801-4701 for help.

3. AC Not Blowing Enough Air

When it seems like you’re not having ample amounts of chilled air, there’s likely an obstruction or detachment inside your AC equipment.

  • The first place is examining your air filter. Buy a new one if it’s dirty.
  • Then check the ductwork is free around your rooms.
  • If you’re still not receiving ample chilly air, you should have your ductwork checked by a specialist like All Weather Heating & Air Conditioning Inc. Your duct system could need to be repaired or reconnected in hard-to-reach areas like your attic, basement or crawl space.
