Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a couple of explanations why your air conditioning system won’t cool: a blown circuit breaker, inaccurate thermostat settings, a shut off switch or a full condensate drain pan.
Overloaded Circuit Breaker
Your AC won’t turn on when you have an overloaded breaker.
To determine if one has gotten overloaded, find your house’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 are dry before you touch the panel or breakers.
- Look for the breaker labeled “AC” and ensure it’s in the “on” spot. If it’s tripped, the switch will be in the middle or “off” location.
- Steadily shift the switch back to the “on” location. If it immediately triggers again, don’t reset it and call us at 570-244-2510. A switch that keeps tripping may mean your residence has an electrical issue.
Inaccurate Thermostat Settings
If your thermostat isn’t signaling your AC to run, it won’t switch on.
The first step is ensuring it’s set to “cool” and not “heat.” Otherwise your AC might not start running. Or you might receive heated air coming from vents being the heater is going instead.
If you have a digital thermostat:
- Swap out the batteries if the monitor is empty. If the screen is showing scrambled letters, get a new thermostat.
- Ensure the right option is showing. If you can’t change it, reverse it by dropping the temperature and pressing the “hold” button. This will cause your AC to run if scheduling is not right.
- Test setting the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat is identical to the house’s temperature.
Once your thermostat is set properly, you should start getting refreshing air quickly.
If you have a smart thermostat, such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you’re still having problems, reach us at 570-244-2510 for help.
Your system typically has a shut-down lever near its condenser. This device is typically in a metal box mounted on your house. If your air conditioner has recently been maintained, the lever may have accidentally been left in the “off” position.
Blocked Condensate Drain Pan
Condensate drain pans keep the additional water your system pulls from the air. This pan is located either beneath or within your furnace or air handler.
When there’s a clog or clogged drain, water can become concentrated and prompt a safety setting to turn off your system.
If your pan involves a PVC pipe or drain, you can get rid of the surplus condensation with a formulated pan-cleaning capsule. You can buy these tablets at a home improvement or hardware shop.
If your pan has a pump, look for the float switch. If the mechanism is “up” and there’s water in the pan, you could need to replace the pump. Reach us at 570-244-2510 for support.
2. AC Blows Warm Air
If your air conditioner is working but not delivering cold air, its airflow could be blocked. Or it could not have sufficient refrigerant.
Your equipment’s airflow can be limited by a clogged air filter or dirty condenser.
How to Replace Your Air Filter
A filthy filter can cause numerous problems, including:
- Reduced comfort
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Higher electricity costs
- Leading your system to wear out faster
We propose changing flat filters every four weeks, and creased filters every three months.
If you can’t recall when you last changed yours, switch off your equipment fully and pull out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It could also be found in an attached filter box or wall-mounted return air grille.
Hold the filter up to the sunshine. If you can’t see any light, you certainly should buy a new filter.
5 Steps to Cleaning Your Cooling System
Weeds, plants and bushes can obstruct your condensing system. This can limit its airflow, impact its energy efficiency and impact your comfort. Here’s how you can get your system operating properly again.
- Turn off electricity completely at the breaker or external device.
- Remove greenery waste around the unit. Once you’ve removed bigger refuse within a two-foot area, you can use a paint brush or vacuum to carefully remove dust from the condenser fins. Deformed fins can also affect efficiency, so you can attempt to correct them with a small knife.
- Take off the upper part of your AC and remove any leaves or grass clippings that has collected. Then wipe down the condenser fan with a damp rag.
- Use a hose nozzle to carefully remove gunk off the fins from inside the equipment. Don’t get moisture on the fan motor.
- Put the top back on and turn the power back on.
When cooling units 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 symptoms that your system is seeping refrigerant:
- It takes a long time to refresh your home and you’re regularly lowering the thermostat.
- Air moving through the registers isn’t as chilled as it should be.
- You’re noticing hissing or burbling noises when the air conditioning works.
- Your evaporator coil is frosty because it’s having an issue handling humidity.
Think your equipment is leaking refrigerant? You need a certified heating and cooling service professional to fix the leak and refill the proper amount of refrigerant in your unit. Contact us at 570-244-2510 for help.
3. AC Not Blowing Enough Air
When it feels like you’re not having enough cold air, there’s probably an obstruction or disconnection somewhere in your cooling unit.
- The first stage is looking at your air filter. Buy a new one if it’s filthy.
- Then check the registers are open throughout your residence.
- If you’re still not getting adequate cold air, you should have your ducts checked by a specialist like Lycoming Heating Company. Your duct system might need to be fixed or hooked up again in hard-to-reach spots like your attic, basement or crawl space.
