Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several causes why your air conditioner won’t run: a tripped circuit breaker, wrong thermostat settings, a turned off switch or an overfull condensate drain pan.
Overloaded Circuit Breaker
Your cooling won’t work when you have an overloaded breaker.
To determine if one has blown, locate 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 are dry before you work on the panel or breakers.
- Locate the breaker labeled “AC” and confirm it’s in the “on” position. If it’s overloaded, the lever will be in the "off" position.
- Firmly move the lever back to the “on” location. If it immediately triggers again, leave it alone and contact us at 541-238-2797. A switch that keeps turning off might indicate your home has electrical trouble.
Inaccurate Thermostat Settings
If your thermostat isn’t giving a sign to your system to start, it won’t turn on.
The first part is checking it’s on “cool” and not “heat.” Otherwise your air conditioning will probably not start running. You could also receive heated air moving from vents since the heater is going instead.
If you have a traditional thermostat:
- Put in new batteries if the readout is empty. If the readout is displaying scrambled characters, buy a new thermostat.
- Make sure the correct mode is showing. If you can’t change it, cancel it by dropping the temperature and pressing the “hold” button. This will force your AC to work if scheduling is wrong.
- Try setting the thermostat 5 degrees cooler than the space’s temperature. Your AC won’t work if the thermostat matches the space’s temperature.
Once your thermostat is calibrated correctly, you should begin getting refreshing air promptly.
If you’re using a smart thermostat, like one produced by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If it still won’t work, reach us at 541-238-2797 for support.
Your AC usually has a power-cutting lever near its outside unit. This switch is typically in a metal box hung on your residence. If your AC has recently been worked on, the device may have accidentally been turned off.
Blocked Condensate Drain Pan
Condensate drain pans hold the extra liquid your AC pulls from the air. This pan is located either below or inside your furnace or air handler.
When there’s an obstruction or clogged drain, water can become concentrated and prompt a safety feature to switch off your air conditioner.
If your pan includes a PVC pipe or drain, you can get rid of the extra condensation with a custom pan-cleaning tab. You can purchase these tablets at a home improvement or hardware retailer.
If your pan has a pump, look for the float switch. If the switch is “up” and there’s liquid in the pan, you might have to replace the pump. Call us at 541-238-2797 for assistance.
2. AC Blows Warm Air
If your equipment is working but not delivering cold air, its airflow might be obstructed. Or it might not have adequate refrigerant.
Your system’s airflow can be limited by a blocked air filter or dusty condenser.
How to Put in a New Your Air Filter
A filthy filter can lead to numerous problems, such as:
- Reduced comfort
- Frosted refrigerant lines or evaporator coil
- Inconsistent cooling
- Higher cooling costs
- Leading your system to wear out faster
We suggest changing flat filters every four weeks, and pleated filters every three months.
If you can’t recall when you last replaced your filter, switch off your AC completely and remove the filter. You can spot the filter in your furnace or air pump’s blower compartment. It could also be found in a connected filter holder or wall-mounted return air grille.
Hold the filter up to the light. If you see a lot of dust, you should get a new one.
4 Tips on Cleaning Your AC Unit
Weeds, plants and leaves can block your condensing unit. This may reduce its airflow, lower its energy efficiency and affect your comfort. Here’s a method you can follow to get your unit running well again.
- Turn off the electrical current totally at the breaker or external switch.
- Get rid of vegetation debris around the air conditioner. Once you’ve cleared all the debris within a two-foot area, you can use a paint brush or vacuum to gingerly clean the unit’s fins. Kinked fins can also impact capability.
- Use a hose nozzle to carefully take off dirt on the fins from inside the equipment. Don’t get water on the fan motor.
- Turn the power back on.
When cooling equipment doesn’t have enough refrigerant, they’ll have difficulty removing heat and humidity from the air.
Here are a couple of symptoms that your unit is losing refrigerant:
- It takes an extended amount of time to cool your space and you’re constantly lowering the thermostat.
- Air coming through the ducts isn’t as chilled as it should be.
- You’re experiencing hissing or bubbling noises when the air conditioning runs.
- Your evaporator coil is iced over on account of having trouble handling humidity.
Worried your equipment is losing refrigerant? You need a authorized heating and cooling service specialist to fix the leak and refill the right level of refrigerant in your system. Get in touch with us at 541-238-2797 for assistance.
3. AC Not Blowing Enough Air
When it appears like you’re not getting enough chilled air, there’s potentially a blockage or detachment somewhere in your cooling unit.
- The first place is looking at your air filter. Get a new one if it’s soiled.
- Make sure the ductwork is open around your rooms.
- If you’re still not receiving sufficient chilled air, you should have your duct system examined by a pro like Tri County Climate Control LLC. Your ducts may need to be fixed or hooked up again in tricky locations like your attic, basement or crawl space.
