Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be several causes why your central AC system won’t run: a triggered circuit breaker, wrong thermostat settings, a turned off switch or an overflowing condensate drain pan.

Triggered Circuit Breaker

Your air conditioning won’t run when you have an overloaded breaker.

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

  • Make sure your hands and feet are free of moisture before you touch the panel or breakers.
  • Look for the breaker marked “AC” and confirm it’s in the “on” spot. If it’s tripped the switch will be in the in between or “off” location.
  • Quickly shift the switch back to the “on” position. If it immediately trips again, don’t touch it and call us at 361-217-7080. A fuse that keeps tripping may signal your home has electrical trouble.

Inaccurate Thermostat Settings

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

The most important point is making sure it’s set to “cool” and not “heat.” Otherwise your AC may not turn on. Or you may get. heated air blowing from vents because the heat is running instead.

If you have a digital thermostat:

  • Put in new batteries if the readout is empty. If the readout is displaying jumbled letters, get a new thermostat.
  • Ensure the right mode is on the display. If you can’t update it, cancel it by lowering the temperature and pressing the “hold” button. This will cause your AC to run if the configuration is not right.
  • Attempt to set the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.

Once your thermostat is set accurately, you should start getting cool air fast.

If you’re using a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If it still won’t work, call us at 361-217-7080 for assistance.

Shut-Down Switch

Your cooling equipment probably has a shut-down lever by its outside unit. This lever is generally in a metal box hung on your residence. If your AC has recently been worked on, the lever may have inadvertently been placed in the “off” setting.

Blocked Condensate Drain Pan

Condensate drain pans keep the additional condensation your AC removes from the air. This pan can be found either under or within your furnace or air handler.

When there’s an obstruction or blocked drain, water can become concentrated and initiate a safety feature to turn off your air conditioner.

If your pan has a PVC pipe or drain, you can drain the surplus water with a special pan-cleaning tablet. You can get these tablets at a home improvement or hardware retailer.

If your pan includes a pump, find the float switch. If the mechanism is “up” and there’s water in the pan, you might have to replace the pump. Contact us at 361-217-7080 for support.

2. AC Blows Warm Air

If your air conditioner is working but not providing cold air, its airflow may be congested. Or it may not have enough refrigerant.

Clogged Airflow

Your equipment’s airflow can be limited by a blocked air filter or filthy condenser.

How to Put in a New Your Air Filter

A dirty filter can create countless problems, such as:

  • Limited comfort
  • Frozen refrigerant lines or evaporator coil
  • Intermittent cooling
  • Larger utility bills
  • Causing your system to wear out more quickly

We suggest installing new flat filters monthly, and creased filters every three months.

If you can’t remember when you last installed a new one, turn off your equipment completely and take out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It could also be situated in a connected 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.

4 Steps to Cleaning Your Air Conditioning System

Weeds, vegetation and shrubbery can get in the way of your condensing equipment. This could limit its airflow, impact its energy efficiency and affect your comfort. Here’s a method you can follow to get your unit running well again.

  1. Turn off the electrical current totally at the breaker or outdoor lever.
  2. Get rid of plant rubbish around the AC. Once you’ve gotten rid of larger debris within a two-foot range, you can use a fine-bristled brush or vacuum to gingerly remove dirt from the equipment’s fins. Bent fins can also hurt efficiency, so you can attempt to correct them with a small knife.
  3. Use a hose nozzle to slowly remove gunk off the fins from inside the equipment. Don’t get water on the fan motor.
  4. Replace the top and turn the power back on.

Leaking Refrigerant

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

Here are a few symptoms that your system is leaking refrigerant:

  1. It takes an extended amount of time to cool your residence and you’re constantly lowering the thermostat.
  2. Air moving through the ducts isn’t as chilly as it should be.
  3. You’re experiencing fizzing or bubbling noises when cooling runs.
  4. Your evaporator coil is frozen due to having an issue absorbing heat.

Suspect your equipment is seeping refrigerant? You need a qualified heating and cooling service specialist to fix the leak and restore the correct measurement of refrigerant in your system. Call us at 361-217-7080 for assistance.

3. AC Not Blowing Enough Air

When it feels like you’re not getting enough cold air, there’s possibly a clog or disconnection within your AC unit.

  • The first step is looking at your air filter. Buy a new one if it’s soiled.
  • Then ensure the vents are open throughout your house.
  • If you’re still not experiencing ample cold air, you should have your duct system examined by a professional like Total Assurance AC & Heating. Your ductwork could need to be repaired or relinked in hard-to-reach areas like your attic, basement or crawl space.
