Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be several reasons why your AC equipment won’t cool: a blown circuit breaker, inaccurate thermostat settings, a switched off switch or a full condensate drain pan.

Tripped Circuit Breaker

Your air conditioner 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 find this silver device on the wall in the basement, garage or closet.

  • Make sure your hands and feet aren’t wet before you touch the panel or breakers.
  • Look for the breaker labeled “AC” and confirm it’s in the “on” position. If it’s overloaded the lever will be in the in between or “off” position.
  • Firmly shift the breaker back to the “on” spot. If it immediately triggers again, don’t touch it and call us at 772-247-2283. A fuse that keeps turning off may indicate your home has an electrical issue.

Inaccurate Thermostat Settings

If your thermostat isn’t giving a sign to your AC to work, it won’t turn on.

The main part is checking it’s set to “cool” and not “heat.” Otherwise your air conditioner might not turn on. Or you may receive. warm air coming from vents since the heat is going instead.

If you have a regular thermostat:

  • Swap out the batteries if the monitor is empty. If the readout is presenting jumbled characters, get a new thermostat.
  • Make sure the right setting is on the display. If you can’t update it, reverse it by decreasing the temperature and hitting 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 cool if the thermostat is set the same as the house’s temperature.

Once your thermostat is set properly, you should start getting chilled air promptly.

If you have a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for assistance. If it still won’t work, reach us at 772-247-2283 for assistance.

Shut-Down Switch

Your air conditioner usually has a power-cutting device around its outside unit. This lever is typically in a metal box hung on your home. If your air conditioner has recently been maintained, the switch may have unintentionally been positioned in the “off” location.

Overflowing Condensate Drain Pan

Condensate drain pans catch the extra condensation your air conditioner pulls from the air. This pan can be found either under or inside your furnace or air handler.

When there’s an obstruction or clogged drain, water can build up and trigger a safety feature to turn off your air conditioner.

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

If your pan involves a pump, look for the float switch. If the lever is “up” and there’s water in the pan, you could need to get a new pump. Reach us at 772-247-2283 for support.

2. AC Blows Warm Air

If your AC is going but not cooling, its airflow may be congested. Or it might not have enough refrigerant.

Obstructed Airflow

Your system’s airflow can be decreased by a blocked air filter or dusty condenser.

How to Change Your Air Filter

A dirty filter can cause numerous troubles, like:

  • Lower cooling
  • Frosted refrigerant lines or evaporator coil
  • Intermittent cooling
  • Increased utility costs
  • Causing your system to stop working faster

We recommend replacing flat filters once a month, and pleated filters every three months.

If you can’t recall when you last installed a new one, turn off your system totally and pull 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 case or wall-mounted return air grille.

Angle the filter up to your light fixture. If you can’t see any light you should buy a new filter.

How to Clean Your AC Equipment

Brush, grass and shrubbery can obstruct your condensing system. This can restrict its airflow, lower its energy efficiency and affect your comfort. Here’s a way you can get your unit working properly again.

  1. Switch off the electrical current completely at the breaker or external switch.
  2. Get rid of plant debris around the unit. Once you’ve cleared all the debris within a two-foot area, you can use a paint brush or vacuum to carefully remove dirt from the unit’s fins. Bent fins can also hurt efficiency, so you can attempt to straighten them with a dinner 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. Install the top again and turn on the power.

Leaking Refrigerant

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

Here are a couple of flags that your system is leaking refrigerant:

  1. It takes an extended amount of time to lower the temperature in your home and you’re regularly lowering the thermostat.
  2. Air conditioning coming through the vents isn’t as cold as it should be.
  3. You’re experiencing hissing or burbling racket when the air conditioning is on.
  4. Your evaporator coil is frozen on account of having an issue absorbing warmth.

Worried your equipment is leaking refrigerant? You need a certified heating and cooling service professional to fix the leak and restore the correct amount of refrigerant in your unit. Contact us at 772-247-2283 for help.

3. AC Not Blowing Enough Air

When it appears like you’re not having ample amounts of cool air, there’s likely a clog or disconnection inside your air conditioning equipment.

  • The beginning stage is looking at your air filter. Replace it if it’s dirty.
  • Then make sure the vents are free across your rooms.
  • If you’re still not experiencing enough chilly air, you should have your duct system examined by a expert like Custom Air Systems Inc. Your ducts could need to be serviced or reconnected in tricky areas like your attic, basement or crawl space.
