Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a few causes why your air conditioning system won’t start: a blown circuit breaker, wrong thermostat settings, a shut off switch or an overfull condensate drain pan.
Blown Circuit Breaker
Your air conditioning won’t start when you have a blown breaker.
To determine if one has gotten overloaded, go to your house’s main electrical panel. You can spot this metallic fixture on the wall in the basement, garage or closet.
- Confirm your hands and feet aren’t wet before you work on the panel or breakers.
- Look for the breaker labeled “AC” and make sure it’s in the “on” spot. If it’s overloaded, the switch will be in the "off" position.
- Firmly transfer the breaker back to the “on” position. If it immediately triggers again, don’t reset it and get in touch with us at 570-322-3131. A breaker that keeps turning off could mean your house has electrical trouble.
Wrong Thermostat Settings
If your thermostat isn’t signaling your air conditioner to work, it won’t turn on.
The key step is checking it’s set to “cool” and not “heat.” Otherwise your air conditioning may not turn on. You may also receive heated air moving from vents because the heat is on instead.
If you rely on a traditional thermostat:
- Swap out the batteries if the monitor is empty. If the monitor is showing garbled numbers, buy a new thermostat.
- Check the proper setting is on the display. If you can’t change it, override it by decreasing the temperature and pressing the “hold” button. This will cause your AC to run if scheduling is incorrect.
- Test setting the thermostat 5 degrees cooler than the space’s temperature. Your AC won’t start if the thermostat is set the same as the room’s temperature.
Once your thermostat is set properly, you should receive refreshing air fast.
If you rely on a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you’re still having problems, contact us at 570-322-3131 for help.
Your cooling equipment usually has a shut-off lever near its outside unit. This switch is generally in a metal box attached to your home. If your AC has recently been fixed, the lever may have inadvertently been turned off.
Overflowing Condensate Drain Pan
Condensate drain pans catch the surplus liquid your air conditioner pulls from the air. This pan is located either below or within your furnace or air handler.
When there’s a blockage or blocked drain, water can become concentrated and prompt a safety feature to turn off your equipment.
If your pan involves a PVC pipe or drain, you can drain the extra liquid with a special pan-cleaning tablet. You can get these tabs at a home improvement or hardware retailer.
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 install a new pump. Call us at 570-322-3131 for help.
2. AC Blows Warm Air
If your equipment is working but not providing cold air, its airflow might be blocked. Or it could not have enough refrigerant.
Your system’s airflow can be restricted by a blocked air filter or dirty condenser.
How to Change Your Air Filter
A dusty filter can lead to many issues, including:
- Limited cooling
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Increased energy bills
- Leading your system to stop working sooner
We propose replacing flat filters monthly, and pleated filters every three months.
If you can’t remember when you last replaced your filter, switch off your unit fully and remove the filter. You can find the filter in your furnace or air pump’s blower compartment. It could also be found in an attached filter case or wall-mounted return air grille.
Angle the filter up to your light fixture. If you can’t see any light, you should get a new one.
4 Tips on Cleaning Your AC System
Weeds, vegetation and leaves can obstruct your condensing equipment. This could restrict its airflow, make it less energy efficient and affect your comfort. Here’s a way you can get your system operating properly again.
- Switch off power totally at the breaker or outdoor device.
- Clear vegetation waste around the equipment. Once you’ve cleared bigger clutter within a two-foot range, you can use a soft brush or vacuum to slowly clean the condenser fins. Kinked fins can also affect capability.
- Use a hose nozzle to slowly clean the fins from inside the equipment. Be careful to avoid getting water on the fan motor.
- Turn on the power.
Not Enough Refrigerant
When cooling systems don’t have ample refrigerant, they’ll have to work much harder to remove heat and humidity from the air.
Here are several indications that your system is seeping refrigerant:
- It takes too long to lower the temperature in your space and you’re regularly lowering the thermostat.
- Air blowing through the vents isn’t as chilled as it should be.
- You’re experiencing fizzing or burbling sounds when the air conditioning runs.
- Your evaporator coil is frozen as a result of having an issue taking on heat.
Think your system is losing refrigerant? You need a authorized heating and cooling service expert to take care of the leak and replenish the correct level of refrigerant in your system. Contact us at 570-322-3131 for assistance.
3. AC Not Blowing Enough Air
When it seems like you’re not receiving ample amounts of cold air, there’s possibly a blockage or separation somewhere in your AC system.
- The first place is checking your air filter. Buy a new one if it’s dusty.
- Make sure the ductwork is open throughout your home.
- If you’re still not getting ample chilled air, you should have your duct system inspected by a expert like Airmen HVAC Service. Your ductwork could need to be fixed or rejoined in tricky locations like your attic, basement or crawl space.
