1. AC Won’t Turn On
There can be a few explanations why your air conditioning system won’t run: a triggered circuit breaker, incorrect thermostat settings, a turned off switch or an overfull condensate drain pan.
Tripped Circuit Breaker
Your air conditioner won’t turn on when you have an overloaded breaker.
To check if one has gotten overloaded, go to your house’s main electrical panel. You can find this gray device on the wall in the basement, garage or closet.
- Ensure your hands and feet aren’t wet before you touch the panel or breakers.
- Locate the breaker marked “AC” and ensure it’s in the “on” spot. If it’s tripped, the switch will be in the in between or “off” spot.
- Firmly move the lever back to the “on” position. If it immediately flips again, don’t touch it and get in touch with us at 949-525-9119. A switch that keeps tripping might mean your house has electrical trouble.
Incorrect Thermostat Settings
If your thermostat isn’t telling your equipment to run, it won’t activate.
The main point is ensuring it’s set to “cool” and not “heat.” Otherwise your AC might not turn on. Or you might have warm air blowing from vents since the furnace is running instead.
If you rely on a regular thermostat:
- Put in new batteries if the readout is empty. If the readout is showing scrambled letters, get a new thermostat.
- Ensure the proper setting is displaying. If you can’t alter it, cancel it by dropping the temperature and hitting the “hold” button. This will cause your AC to run if programming is not right.
- Try setting the thermostat 5 degrees colder than the space’s temperature. Your AC won’t cool if the thermostat matches the house’s temperature.
Once your thermostat is adjusted correctly, you should receive cool air quickly.
If you have a smart thermostat, like one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you’re still having problems, reach us at 949-525-9119 for help.
Turn-Off Switch
Your air conditioner probably has a shut-down switch near its condenser. This device is commonly in a metal box mounted on your residence. If your unit has recently been repaired, the lever may have unintentionally been positioned in the “off” location.
Clogged Condensate Drain Pan 
Condensate drain pans keep the additional water your equipment pulls from the air. This pan is located either beneath or inside your furnace or air handler.
When there’s an obstruction or backed up drain, water can build up and prompt a safety setting to switch off your unit.
If your pan involves a PVC pipe or drain, you can get rid of the additional liquid with a custom pan-cleaning tab. You can purchase these capsules at a home improvement or hardware store.
If your pan includes a pump, locate the float switch. If the lever is “up” and there’s liquid in the pan, you could need to get a new pump. Call us at 949-525-9119 for help.
2. AC Blows Warm Air
If your equipment is on but not providing cold air, its airflow might be clogged. Or it could not have adequate refrigerant.
Blocked Airflow
Your unit’s airflow can be decreased by a blocked air filter or filthy condenser.
How to Change Your Air Filter
A filthy filter can create a lot of problems, such as:
- Reduced comfort
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Larger cooling expenses
- Leading your system to stop working more quickly
We propose replacing flat filters monthly, and creased filters every three months.
If you aren’t sure when you last changed yours, switch off your system completely and remove the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be situated in an attached filter box or wall-mounted return air grille.
Hold the filter up to the light. If you can’t see any light, you should replace it.
How to Clean Your Cooling Equipment
Greenery, grass and sticks can obstruct your condensing system. This may limit its airflow, lower its energy efficiency and impact your comfort. Here’s how you can get your unit operating smoothly again.
- Turn off electricity fully at the breaker or outside switch.
- Remove greenery waste around the AC. Once you’ve removed larger clutter within a two-foot area, you can use a paint brush or vacuum to gingerly remove dirt from the unit’s fins. Misshapen fins can also hurt effectiveness, so you can attempt to straighten them with a dinner knife.
- Lift off the upper part of your system and take out any leaves or sticks that has collected. Then wipe off the condenser fan with a damp scrap cloth.
- Use a hose nozzle to carefully remove gunk off the fins from inside the equipment. Make sure to avoid getting liquid on the fan motor.
- Put the top back on and turn the power back on.
Leaking Refrigerant
When air conditioning units don’t have ample refrigerant, they’ll have to work much harder to remove heat and humidity from your home.
Here are a few signs that your system is leaking refrigerant:
- It takes a long time to lower the temperature in your rooms and you’re constantly lowering the thermostat.
- Cooling coming through the vents isn’t as chilly as it should be.
- You’re noticing hissing or gurgling noises when the AC is on.
- Your evaporator coil is icy on account of having an issue taking on humidity.
Think your system is seeping refrigerant? You need a authorized heating and cooling service professional to repair the leak and restore the right amount of refrigerant in your equipment. Contact us at 949-525-9119 for assistance.
3. AC Not Blowing Enough Air
When it appears like you’re not receiving ample amounts of chilled air, there’s usually an obstruction or disconnection somewhere in your AC equipment.
- The beginning place is examining your air filter. Buy a new one if it’s dirty.
- Then check the vents are clear around your rooms.
- If you’re still not experiencing enough cold air, you should have your ductwork inspected by a expert like Ocean Air Conditioning and Heating . Your duct system could need to be serviced or hooked up again in limited space spots like your attic, basement or crawl space.
