Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several explanations why your AC equipment won’t work: an overloaded circuit breaker, wrong thermostat settings, a shut off switch or an overfull condensate drain pan.
Blown Circuit Breaker
Your AC won’t work when you have a tripped breaker.
To check if one has blown, go to your residence’s main electrical panel. You can locate this metallic 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.
- Locate the breaker labeled “AC” and make sure it’s in the “on” location. If it’s tripped, the lever will be in the "off" position.
- Firmly move the lever back to the “on” spot. If it instantly triggers again, don’t touch it and call us at 740-200-5591. A switch that keeps flipping could indicate your home has an electrical issue.
Wrong Thermostat Settings
If your thermostat isn’t signaling your air conditioner to work, it won’t switch on.
The key part is making sure it’s set to “cool” and not “heat.” Otherwise your AC may not start running. You could also get heated air blowing from vents since the heat is running instead.
If you rely on a regular thermostat:
- Replace the batteries if the readout is clear. If the screen is displaying jumbled characters, get a new thermostat.
- Make sure the right option is on the display. If you can’t alter it, override it by decreasing the temperature and pushing the “hold” button. This will make your AC start if the configuration is not right.
- Test setting the thermostat 5 degrees below the house’s temperature. Your AC won’t cool if the thermostat is set the same as the space’s temperature.
Once your thermostat is adjusted 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, look at the manufacturer’s website for assistance. If you’re still having problems, reach us at 740-200-5591 for assistance.
Your AC usually has a shut-off device by its condenser. This device is typically in a metal box mounted on your house. If your air conditioner has recently been serviced, the device may have accidentally been turned off.
Clogged Condensate Drain Pan
Condensate drain pans keep the surplus liquid your air conditioner removes from the air. This pan can be situated either below or inside your furnace or air handler.
When there’s an obstruction or clogged drain, water can build up and prompt a safety setting to turn off your system.
If your pan includes a PVC pipe or drain, you can get rid of the extra condensation with a formulated pan-cleaning tab. You can purchase these capsules at a home improvement or hardware store.
If your pan involves a pump, find the float switch. If the switch is “up” and there’s liquid in the pan, you could need to get a new pump. Contact us at 740-200-5591 for help.
2. AC Blows Warm Air
If your equipment is going but not delivering cold air, its airflow might be clogged. Or it may not have enough refrigerant.
Your system’s airflow can be decreased by a blocked air filter or dusty condenser.
How to Replace Your Air Filter
A dusty filter can lead to a lot of issues, like:
- Lower airflow
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Bigger cooling bills
- Leading your system to break down faster
We propose replacing flat filters monthly, and pleated filters every three months.
If you can’t recall when you last replaced your filter, switch off your AC completely and pull out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It might also be found in an adjoining filter holder or wall-mounted return air grille.
Angle the filter up to your light fixture. If you see a lot of dust, you need to get a new one.
4 Tips on Cleaning Your Cooling Equipment
Brush, grass and shrubbery can block your condensing system. This could restrict its airflow, impact its energy efficiency and impact your comfort. Here’s a method you can follow to get your equipment operating smoothly again.
- Switch off power totally at the breaker or outside switch.
- Get rid of plant rubbish around the AC. Once you’ve gotten rid of all the clutter within a two-foot space, you can use a paint brush or vacuum to slowly remove dirt from the unit’s fins. Deformed fins can also hurt effectiveness.
- Use a hose nozzle to slowly clean the fins from inside the unit. Don’t get water on the fan motor.
- Turn on the power.
When air conditioning equipment doesn’t have ample refrigerant, they’ll struggle to remove heat and humidity from your rooms.
Here are a couple of flags that your unit is losing refrigerant:
- It takes an extended amount of time to lower the temperature in your residence and you’re continually turning down the thermostat.
- Air coming through the ducts isn’t as cold as it should be.
- You’re hearing whistling or gurgling sounds when the AC is on.
- Your evaporator coil is icy on account of having trouble absorbing heat.
Suspect your equipment is losing refrigerant? You need a licensed heating and cooling service specialist to repair the leak and replenish the proper level of refrigerant in your unit. Contact us at 740-200-5591 for assistance.
3. AC Not Blowing Enough Air
When it feels like you’re not receiving adequate amounts of chilled air, there’s potentially an obstruction or detachment somewhere in your AC unit.
- The beginning stage is examining your air filter. Replace it if it’s dusty.
- Make sure the ductwork is open around your rooms.
- If you’re still not getting adequate chilly air, you should have your ductwork inspected by a specialist like Luikart Heating & Cooling. Your ducts might need to be fixed or relinked in hard-to-reach areas like your attic, basement or crawl space.
