Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be several reasons why your air conditioning won’t start: a triggered circuit breaker, wrong thermostat settings, a switched off switch or a full condensate drain pan.

Blown Circuit Breaker

Your AC won’t run when you have a blown breaker.

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

  • Ensure your hands and feet are free of moisture before you touch the panel or breakers.
  • Find the breaker identified “AC” and make sure it’s in the “on” location. If it’s tripped the lever will be in the middle or “off” location.
  • Firmly transfer the lever back to the “on” location. If it instantly triggers again, don’t reset it and call us at 662-281-1231. A breaker that keeps tripping may indicate your residence has an electrical problem.

Inaccurate Thermostat Settings

If your thermostat isn’t signaling your system to start, it won’t turn on.

The first step is making sure it’s on “cool” and not “heat.” Otherwise your AC may not turn on. Or you may receive. hot air coming from vents because the heater is running instead.

If you’re using a traditional thermostat:

  • Swap out the batteries if the screen is blank. If the monitor is displaying scrambled numbers, buy a new thermostat.
  • Ensure the proper program is displaying. If you can’t update it, cancel it by lowering the temperature and pushing the “hold” button. This will force your AC to work if programming is incorrect.
  • Attempt to set the thermostat 5 degrees below the house’s temperature. Your AC won’t start if the thermostat is set the same as the house’s temperature.

Once your thermostat is adjusted properly, you should receive chilled air promptly.

If you’re using a smart thermostat, like one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for assistance. If you still can’t get it to work, reach us at 662-281-1231 for support.

Shut-Down Switch

Your air conditioner usually has a shut-off device around its outdoor unit. This device is typically in a metal box attached to your home. If your air conditioner has recently been maintained, the lever may have inadvertently been put in the “off” setting.

Blocked Condensate Drain Pan

Condensate drain pans hold the additional liquid your AC takes out of the air. This pan can be situated either beneath or within your furnace or air handler.

When there’s a blockage or blocked drain, water can accumulate and trigger a safety control to stop your air conditioner.

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

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 662-281-1231 for assistance.

2. AC Blows Warm Air

If your system is on but not providing cold air, its airflow might be clogged. Or it could not have sufficient refrigerant.

Obstructed Airflow

Your unit’s airflow can be reduced by a blocked air filter or dusty condenser.

How to Replace Your Air Filter

A dirty filter can create a lot of troubles, including:

  • Lower cooling
  • Frozen refrigerant lines or evaporator coil
  • Uneven cooling
  • Bigger cooling costs
  • Making your system stop working more quickly

We propose replacing 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 system fully and remove the filter. You can locate the filter in your furnace or air pump’s blower compartment. It might also be situated in a connected filter box or wall-mounted return air grille.

Hold the filter up to the light. If you can’t see through it you should buy a new filter.

4 Tips on Cleaning Your AC System

Weeds, plants and shrubbery 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 running well again.

  1. Switch off electricity fully at the breaker or external device.
  2. Get rid of plant waste around the AC. Once you’ve cleared bigger refuse within a two-foot space, you can use a paint brush or vacuum to slowly remove dust from the condenser fins. Bent fins can also impact effectiveness, so you can attempt to reshape them with a dinner knife.
  3. Use a hose nozzle to slowly clean the fins from inside the system. Don’t get moisture on the fan motor.
  4. Put the top back on and turn on the power.

Leaking Refrigerant

When cooling units don’t have ample refrigerant, they’ll have difficulty removing heat and humidity from your house.

Here are a couple of indications that your unit is seeping refrigerant:

  1. It takes a long time to lower the temperature in your home and you’re constantly decreasing the temperature on the thermostat.
  2. Cooling moving through the registers isn’t as chilly as it should be.
  3. You’re hearing hissing or bubbling sounds when cooling runs.
  4. Your evaporator coil is frosted due to having trouble absorbing warmth.

Think your system is leaking refrigerant? You need a qualified heating and cooling service specialist to fix the leak and restore the right measurement of refrigerant in your equipment. Reach us at 662-281-1231 for help.

3. AC Not Blowing Enough Air

When it appears like you’re not receiving ample amounts of cool air, there’s possibly a blockage or separation inside your air conditioning unit.

  • The initial place is looking at your air filter. Buy a new one if it’s dirty.
  • Then make sure the ductwork is free across your rooms.
  • If you’re still not receiving sufficient cold air, you should have your ducts examined by a expert like Franklin's Heating & Air Conditioning, Inc. Your ductwork may need to be fixed or hooked up again in hard-to-reach areas like your attic, basement or crawl space.
