Air Conditioner Repair Checklist

1. AC Won’t Turn On

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

Blown Circuit Breaker

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

To determine if one has tripped, go to your house’s main electrical panel. You can spot this silver device on the wall in the basement, garage or closet.

  • Confirm your hands and feet are free of moisture before you touch the panel or breakers.
  • Look for the breaker marked “AC” and ensure it’s in the “on” spot. If it’s tripped the breaker will be in the middle or “off” spot.
  • Quickly shift the switch back to the “on” location. If it immediately triggers again, don’t reset it and get in touch with us at 713-364-9957. A fuse that keeps tripping may signal your residence has an electrical problem.

Inaccurate 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 set to “cool” and not “heat.” Otherwise your AC will probably not start running. Or you might have. warm air blowing from vents since the heat is on instead.

If you rely on a digital thermostat:

  • Swap out the batteries if the screen is blank. If the readout is presenting garbled characters, replace the thermostat.
  • Ensure the right mode is displaying. If you can’t alter it, reverse it by dropping the temperature and pushing the “hold” button. This will cause your AC to run if scheduling is incorrect.
  • Attempt to set the thermostat 5 degrees below the space’s temperature. Your AC won’t work if the thermostat matches the space’s temperature.

Once your thermostat is calibrated properly, you should receive chilled air quickly.

If you’re using a smart thermostat, like one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you’re still having problems, call us at 713-364-9957 for assistance.

Turn-Off Switch

Your system usually has a shut-off lever near its outdoor unit. This switch is generally in a metal box attached to your house. If your air conditioner has recently been tuned up, the device may have unintentionally been left in the “off” setting.

Blocked Condensate Drain Pan

Condensate drain pans keep the extra water your AC takes out of the air. This pan is located either below or inside your furnace or air handler.

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

If your pan involves a PVC pipe or drain, you can get rid of the surplus liquid with a formulated pan-cleaning tablet. You can purchase these tablets at a home improvement or hardware retailer.

If your pan involves a pump, find the float switch. If the lever is “up” and there’s water in the pan, you might have to get a new pump. Call us at 713-364-9957 for support.

2. AC Blows Warm Air

If your equipment is on but not delivering cold air, its airflow might be clogged. Or it could not have enough refrigerant.

Blocked Airflow

Your equipment’s airflow can be restricted by a plugged air filter or filthy condenser.

How to Replace Your Air Filter

A dirty filter can create many troubles, like:

  • Limited comfort
  • Frozen refrigerant lines or evaporator coil
  • Uneven cooling
  • Larger cooling expenses
  • Leading your system to break down faster

We recommend changing flat filters every four weeks, and accordion filters every three months.

If you aren’t sure when you last installed a new one, switch off your AC totally and remove the filter. You can spot 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.

Angle the filter up to the light. If you can’t see through it you should get a new one.

4 Steps to Cleaning Your AC Equipment

Greenery, plants and shrubbery can get in the way of your condensing unit. This can restrict its airflow, make it less energy efficient and impact your comfort. Here’s a method you can follow to get your equipment running smoothly again.

  1. Shut off the electrical current completely at the breaker or external switch.
  2. Remove greenery rubbish around the equipment. Once you’ve gotten rid of all the refuse within a two-foot area, you can use a soft brush or vacuum to gingerly remove dirt from the unit’s fins. Kinked fins can also impact efficiency, so you can attempt to adjust them with a small knife.
  3. Use a hose nozzle to carefully clean the fins from inside the equipment. Be careful to avoid getting water on the fan motor.
  4. Put the top back on and turn the power back on.

Insufficient Refrigerant

When cooling equipment doesn’t have ample refrigerant, they’ll struggle to remove heat and humidity from the air.

Here are several symptoms that your system is losing refrigerant:

  1. It takes a long time to refresh your rooms and you’re continually lowering the thermostat.
  2. Air conditioning blowing through the vents isn’t as chilly as it should be.
  3. You’re noticing fizzing or gurgling sounds when cooling runs.
  4. Your evaporator coil is frozen as a result of having trouble handling warmth.

Worried your system is losing refrigerant? You need a qualified heating and cooling service expert to take care of the leak and restore the correct measurement of refrigerant in your equipment. Contact us at 713-364-9957 for assistance.

3. AC Not Blowing Enough Air

When it seems like you’re not having ample amounts of cold air, there’s likely a blockage or disconnection within your air conditioning system.

  • The first step is looking at your air filter. Get a new one if it’s soiled.
  • Then check the ductwork is free around your residence.
  • If you’re still not experiencing enough cold air, you should have your ducts checked by a professional like Premium Air Services LLC. Your ducts may need to be serviced or relinked in limited space areas like your attic, basement or crawl space.
