1. AC Won’t Turn On
There can be a few explanations why your air conditioner won’t work: an overloaded circuit breaker, wrong thermostat settings, a turned off switch or an overfull condensate drain pan.
Triggered Circuit Breaker
Your AC won’t turn on when you have a tripped breaker.
To check if one has tripped, find your home’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 identified “AC” and ensure it’s in the “on” spot. If it’s tripped, the lever will be in the middle of the panel or “off” position.
- Steadily transfer the switch back to the “on” position. If it instantaneously flips again, don’t reset it and get in touch with us at 714-855-1717. A breaker that keeps flipping may indicate your residence has an electrical issue.
Inaccurate Thermostat Settings
If your thermostat isn’t giving a sign to your AC to run, it won’t switch on.
The key step is ensuring it’s switched to “cool” and not “heat.” Otherwise your air conditioning may not start running. Or you may have heated air blowing from vents because the heater is on instead.
If you’re using a digital thermostat:
- Swap out the batteries if the monitor is clear. If the screen is displaying jumbled letters, get a new thermostat.
- Check the right option is on the display. If you can’t alter it, override it by lowering the temperature and pushing the “hold” button. This will make your AC start if programming is wrong.
- Try setting the thermostat 5 degrees lower than 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 calibrated correctly, you should start getting cold air fast.
If you rely on a smart thermostat, including ones 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 714-855-1717 for help.
Your air conditioner usually has a shut-off switch by its outside unit. This device is generally in a metal box mounted on your house. If your equipment has recently been fixed, the switch may have accidentally been placed in the “off” setting.
Blocked Condensate Drain Pan
Condensate drain pans keep the surplus water your equipment pulls from the air. This pan can be found either beneath or inside your furnace or air handler.
When there’s a blockage or blocked drain, water can accumulate and initiate a safety setting to stop your unit.
If your pan involves a PVC pipe or drain, you can clear the additional water with a special pan-cleaning capsule. You can purchase these tablets at a home improvement or hardware store.
If your pan includes a pump, find the float switch. If the lever is “up” and there’s liquid in the pan, you could need to install a new pump. Reach us at 714-855-1717 for support.
2. AC Blows Warm Air
If your equipment is working but not providing cold air, its airflow might be clogged. Or it might not have adequate refrigerant.
Your system’s airflow can be restricted by a clogged air filter or filthy condenser.
How to Change Your Air Filter
A filthy filter can cause numerous troubles, like:
- Reduced comfort
- Icy refrigerant lines or evaporator coil
- Intermittent cooling
- Larger cooling costs
- Leading your system to stop working sooner
We recommend installing new flat filters monthly, and accordion filters every three months.
If you aren’t sure when you last changed yours, turn off your unit totally and take out the filter. You can find the filter in your furnace or air pump’s blower compartment. It may also be located in a connected filter holder or wall-mounted return air grille.
Angle the filter up to the sunshine. If you can’t see through it, you certainly should replace it.
How to Clean Your Cooling System
Greenery, grass and leaves can block your condensing system. This may restrict its airflow, lower its energy efficiency and change your comfort. Here’s a way you can get your system operating well again.
- Turn off power totally at the breaker or outside switch.
- Remove plant rubbish around the air conditioner. Once you’ve removed bigger clutter within a two-foot range, you can use a fine-bristled brush or vacuum to carefully remove dirt from the unit’s fins. Deformed fins can also affect capability, so you can attempt to correct them with a small knife.
- Take off the upper grate of your unit and remove any leaves or sticks that has collected. Then wipe off the condenser fan with a moist rag.
- Use a hose nozzle to slowly take off dirt on the fins from inside the unit. Don’t get liquid on the fan motor.
- Replace the top and restore the power.
Low Refrigerant Levels
When cooling units don’t have enough refrigerant, they’ll struggle to remove heat and humidity from your rooms.
Here are a couple of symptoms that your equipment is seeping refrigerant:
- It takes an extended amount of time to cool your residence and you’re constantly decreasing the temperature on the thermostat.
- Air moving through the vents isn’t as chilly as it should be.
- You’re hearing fizzing or bubbling noises when the AC works.
- Your evaporator coil is icy because it’s having difficulty absorbing heat.
Worried your unit is losing refrigerant? You need a licensed heating and cooling service professional to take care of the leak and restore the right measurement of refrigerant in your unit. Contact us at 714-855-1717 for help.
3. AC Not Blowing Enough Air
When it feels like you’re not receiving enough cold air, there’s likely an obstruction or disconnection somewhere in your air conditioning system.
- The first place is looking at your air filter. Buy a new one if it’s dusty.
- Then make sure the vents are free around your home.
- If you’re still not experiencing adequate chilled air, you should have your ductwork inspected by a specialist like Eco Fresh HVAC Inc.. Your duct system may need to be serviced or hooked up again in tricky areas like your attic, basement or crawl space.
