1. AC Won’t Turn On
There can be several explanations why your air conditioning system won’t cool: a tripped circuit breaker, inaccurate thermostat settings, a turned off switch or an overflowing condensate drain pan.
Tripped Circuit Breaker
Your cooling won’t run when you have a tripped breaker.
To find out if one has blown, locate your home’s main electrical panel. You can spot this gray device on the wall in the basement, garage or closet.
- Confirm your hands and feet aren’t wet before you touch the panel or breakers.
- Find the breaker identified “AC” and ensure it’s in the “on” spot. If it’s triggered, the switch will be in the in between or “off” location.
- After ensuring the breaker has been switched to the OFF position, move one hand and steadily flip the breaker to the “on” position. If it instantly trips again, leave it alone and call us at 715-301-0727. A breaker that keeps tripping might indicate your home has an electrical issue.
Inaccurate Thermostat Settings
If your thermostat isn’t signaling your system to run, it won’t activate.
The most important point is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioning may not start running. Or you could receive heated air blowing from vents being the heater is on instead.
If you’re using a regular thermostat:
- Put in new batteries if the screen is blank. If the screen is presenting garbled letters, buy a new thermostat.
- Ensure the correct mode is showing. If you can’t update it, override it by dropping the temperature and pushing the “hold” button. This will force your AC to work if the configuration is not right.
- Attempt to set the thermostat 5 degrees below the room’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 cold air quickly.
If you’re using a smart thermostat, including ones manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for troubleshooting. If it still won’t work, reach us at 715-301-0727 for support.
Turn-Off Switch
Your AC typically has a shut-down device around its outside unit. This switch is generally in a metal box attached to your home. If your unit has recently been worked on, the device may have unintentionally been positioned in the “off” setting.
2. AC Blows Warm Air
If your air conditioner is working but not providing cold air, its airflow might be clogged. Or it could not have sufficient refrigerant.
Clogged Airflow
Your equipment’s airflow can be decreased by a blocked air filter or filthy condenser.
How to Replace Your Air Filter
A dirty filter can create numerous issues, like:
- Reduced airflow
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Larger utility expenses
- Leading your system to stop working sooner
We propose installing new flat filters monthly, and accordion filters every three months.
If you can’t recall when you last installed a new one, switch off your equipment completely and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It may also be found in a connected filter box or wall-mounted return air grille.
Hold the filter up to your light fixture. If you can’t see any light, you need to replace it.
How to Clean Your Air Conditioning Unit
Weeds, plants and bushes can get in the way of your condensing unit. This can reduce its airflow, lower its energy efficiency and impact your comfort. Here’s a way you can get your equipment operating properly again.
- Turn off the electrical current completely at the breaker or outdoor device.
- Clear vegetation waste around the equipment. Once you’ve removed bigger clutter within a two-foot area, you can use a paint brush or vacuum to gingerly clean the equipment’s fins.
Insufficient Refrigerant
When air conditioning systems don’t have ample refrigerant, they’ll have to work much harder to remove heat and humidity from the air.
Here are a couple of signs that your unit is losing refrigerant:
- It takes too long to lower the temperature in your space and you’re continually decreasing the temperature on the thermostat.
- Air conditioning coming through the registers isn’t as chilled as it should be.
- You’re experiencing whistling or bubbling racket when the AC is on.
- Your evaporator coil is iced over as a result of having trouble handling humidity.
Suspect your equipment is seeping refrigerant? You need a qualified heating and cooling service expert to fix the leak and restore the correct amount of refrigerant in your equipment. Get in touch with us at 715-301-0727 for support.
3. AC Not Blowing Enough Air
When it feels like you’re not getting enough chilled air, there’s usually an obstruction or disconnection somewhere in your cooling equipment.
- The initial step is looking at your air filter. Replace it if it’s soiled.
- Then make sure the registers are free throughout your rooms.
- If you’re still not receiving adequate chilly air, you should have your ductwork examined by a pro like Gilray Heating and Cooling. Your ducts may need to be fixed or reconnected in hard-to-reach locations like your attic, basement or crawl space.
