1. AC Won’t Turn On
There can be several reasons why your air conditioner won’t cool: a tripped circuit breaker, incorrect thermostat settings, a switched off switch or a full condensate drain pan.
Triggered Circuit Breaker
Your cooling won’t run when you have a tripped breaker.
To see if one has gotten overloaded, find your residence’s main electrical panel. You can locate this metallic box on the wall in the basement, garage or closet.
- Make sure your hands and feet aren’t wet before you check the panel or breakers.
- Find the breaker labeled “AC” and ensure it’s in the “on” position. If it’s tripped, the breaker will be in the middle or “off” spot.
- Steadily shift the lever back to the “on” position. If it instantaneously flips again, don’t touch it and call us at 302-231-1380. A breaker that keeps flipping could signal your residence has electrical trouble.
Wrong Thermostat Settings
If your thermostat isn’t signaling your system to work, it won’t switch on.
The key part is ensuring it’s set to “cool” and not “heat.” Otherwise your air conditioner may not turn on. Or you might get heated air moving from vents being the heat is going instead.
If you rely on a regular thermostat:
- Swap out the batteries if the readout is empty. If the screen is displaying scrambled characters, buy a new thermostat.
- Check the correct option is displaying. If you can’t update it, cancel it by dropping the temperature and pressing the “hold” button. This will force your AC to work if the configuration is not right.
- Test setting the thermostat 5 degrees lower than the house’s temperature. Your AC won’t work if the thermostat is identical to the room’s temperature.
Once your thermostat is set correctly, you should begin getting cool air promptly.
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, call us at 302-231-1380 for assistance.
Your system usually has a shut-down lever by its outdoor unit. This device is generally in a metal box attached to your house. If your air conditioner has recently been maintained, the switch may have inadvertently been placed in the “off” setting.
Overflowing Condensate Drain Pan
Condensate drain pans hold the additional water your air conditioner removes from the air. This pan can be situated either below or inside your furnace or air handler.
When there’s a clog 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 clear the surplus water with a custom pan-cleaning capsule. You can get these tabs at a home improvement or hardware retailer.
If your pan includes a pump, find the float switch. If the mechanism is “up” and there’s liquid in the pan, you might have to replace the pump. Contact us at 302-231-1380 for assistance.
2. AC Blows Warm Air
If your equipment is working but not providing cold air, its airflow could be obstructed. Or it could not have enough refrigerant.
Your system’s airflow can be decreased by a blocked air filter or dusty condenser.
How to Put in a New Your Air Filter
A dusty filter can lead to numerous troubles, such as:
- Lower cooling
- Icy refrigerant lines or evaporator coil
- Uneven cooling
- Higher electricity costs
- Causing your system to stop working sooner
We propose changing flat filters monthly, and accordion filters every three months.
If you can’t remember when you last changed yours, shut off your system completely and pull out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It could also be located in a connected filter holder or wall-mounted return air grille.
Tilt the filter up to your light fixture. If you can’t see any light, you certainly should buy a new filter.
5 Steps to Cleaning Your Cooling Unit
Greenery, vegetation and bushes can get in the way of your condensing equipment. This could limit its airflow, lower its energy efficiency and impact your comfort. Here’s how you can get your system working properly again.
- Switch off power fully at the breaker or outdoor device.
- Get rid of greenery waste around the air conditioner. Once you’ve gotten rid of larger clutter within a two-foot space, you can use a fine-bristled brush or vacuum to gingerly remove dirt from the unit’s fins. Warped fins can also impact performance, so you can attempt to adjust them with a blunt knife.
- Take off the upper grate of your air conditioner and remove any leaves or weeds that has built up. Then wipe off the condenser fan with a moist scrap cloth.
- Use a hose nozzle to carefully remove gunk off the fins from inside the system. Don’t get moisture on the fan motor.
- Replace the top and turn on the power.
Not Enough Refrigerant
When air conditioning units don’t have enough refrigerant, they’ll struggle to remove heat and humidity from your space.
Here are a couple of symptoms that your equipment is leaking refrigerant:
- It takes too long to lower the temperature in your home and you’re constantly turning down the thermostat.
- Air conditioning blowing through the vents isn’t as chilly as it should be.
- You’re experiencing hissing or gurgling racket when cooling runs.
- Your evaporator coil is frosted as a result of having trouble handling heat.
Think your system is leaking refrigerant? You need a authorized heating and cooling service specialist to take care of the leak and replenish the proper measurement of refrigerant in your system. Get in touch with us at 302-231-1380 for help.
3. AC Not Blowing Enough Air
When it appears like you’re not having adequate amounts of cold air, there’s likely a blockage or disconnection within your cooling equipment.
- The beginning stage is looking at your air filter. Get a new one if it’s filthy.
- Then check the vents are clear across your house.
- If you’re still not getting adequate cold air, you should have your ductwork checked by a expert like SchagrinGAS Company. Your ductwork might need to be fixed or rejoined in hard-to-reach spots like your attic, basement or crawl space.
