Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several explanations why your AC equipment won’t run: a blown circuit breaker, inaccurate thermostat settings, a switched off switch or an overflowing condensate drain pan.
Blown Circuit Breaker
Your cooling won’t start when you have a blown breaker.
To check if one has tripped, go to your house’s main electrical panel. You can locate this metallic box on the wall in the basement, garage or closet.
- Ensure your hands and feet are free of moisture before you check the panel or breakers.
- Find the breaker labeled “AC” and make sure it’s in the “on” position. If it’s overloaded, the lever will be in the "off" position.
- Firmly move the switch back to the “on” spot. If it instantaneously triggers again, don’t touch it and contact us at 918-212-8943. A fuse that keeps flipping may indicate your house has an electrical problem.
Wrong Thermostat Settings
If your thermostat isn’t giving a sign to your AC to work, it won’t turn on.
The most important part is checking it’s set to “cool” and not “heat.” Otherwise your air conditioner may not start running. You could also get warm air blowing from vents being the furnace is running instead.
If you rely on a traditional thermostat:
- Swap out the batteries if the readout is blank. If the monitor is displaying jumbled numbers, buy a new thermostat.
- Make sure the right mode is displaying. If you can’t update it, cancel it by decreasing the temperature and hitting the “hold” button. This will cause your AC to run if the configuration is not right.
- Test setting the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat is identical to the room’s temperature.
Once your thermostat is calibrated correctly, you should receive refreshing air quickly.
If you rely on a smart thermostat, including ones manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If it still won’t work, reach us at 918-212-8943 for help.
Turn-Off Switch
Your AC usually has a power-cutting switch near its condenser. This lever is typically in a metal box mounted on your residence. If your air conditioner has recently been serviced, the lever may have inadvertently been turned off.
Overflowing Condensate Drain Pan 
Condensate drain pans keep the surplus water your equipment takes out of the air. This pan is located either beneath or within your furnace or air handler.
When there’s a blockage or clogged drain, water can become concentrated and prompt a safety control to turn off your system.
If your pan has a PVC pipe or drain, you can get rid of the extra water with a special pan-cleaning tab. You can purchase these capsules at a home improvement or hardware store.
If your pan involves a pump, locate the float switch. If the lever is “up” and there’s water in the pan, you might have to install a new pump. Contact us at 918-212-8943 for help.
2. AC Blows Warm Air
If your AC is on but not cooling, its airflow could be congested. Or it could not have enough refrigerant.
Blocked Airflow
Your system’s airflow can be reduced by a clogged air filter or filthy condenser.
How to Replace Your Air Filter
A dusty filter can lead to a lot of troubles, such as:
- Lower comfort
- Frosted refrigerant lines or evaporator coil
- Inconsistent cooling
- Bigger electricity bills
- Causing your system to wear out sooner
We recommend replacing flat filters every four weeks, and pleated filters every three months.
If you can’t recall when you last replaced your filter, shut off your equipment totally and take out the filter. You can find the filter in your furnace or air pump’s blower compartment. It could also be located in a connected filter box or wall-mounted return air grille.
Angle the filter up to the sunshine. If you see a lot of dust, you certainly should get a new one.
4 Tips on Cleaning Your Air Conditioning Equipment
Brush, vegetation and shrubbery can block your condensing system. This can restrict its airflow, make it less energy efficient and impact your comfort. Here’s a method you can follow to get your unit running properly again.
- Shut off power completely at the breaker or outside device.
- Clear yard rubbish around the AC. Once you’ve cleared larger clutter within a two-foot space, you can use a fine-bristled brush or vacuum to gingerly remove dirt from the condenser fins. Distorted fins can also affect effectiveness.
- Use a hose nozzle to gingerly remove gunk off the fins from inside the unit. Be careful to avoid getting moisture on the fan motor.
- Restore the power.
Leaking Refrigerant
When air conditioning units don’t have adequate refrigerant, they’ll struggle to remove heat and humidity from your space.
Here are a few signs that your system is leaking refrigerant:
- It takes an extended amount of time to cool your space and you’re continually decreasing the temperature on the thermostat.
- Air conditioning coming through the ducts isn’t as chilled as it should be.
- You’re experiencing fizzing or bubbling sounds when the air conditioning runs.
- Your evaporator coil is frozen as a result of having an issue handling humidity.
Think your equipment is losing refrigerant? You need a authorized heating and cooling service specialist to fix the leak and replenish the proper amount of refrigerant in your equipment. Call us at 918-212-8943 for support.
3. AC Not Blowing Enough Air
When it seems like you’re not getting ample amounts of chilled air, there’s potentially an obstruction or detachment within your air conditioning unit.
- The beginning stage is checking your air filter. Get a new one if it’s filthy.
- Make sure the vents are open around your home.
- If you’re still not receiving enough cold air, you should have your duct system examined by a expert like Air Service Co.. Your ductwork could need to be fixed or reconnected in limited space areas like your attic, basement or crawl space.
