Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a few causes why your AC equipment won’t cool: a blown circuit breaker, wrong thermostat settings, a shut off switch or an overfull condensate drain pan.
Triggered Circuit Breaker
Your air conditioner won’t start when you have a blown breaker.
To find out if one has blown, find your home’s main electrical panel. You can find this metallic device on the wall in the basement, garage or closet.
- Confirm your hands and feet aren’t wet before you check the panel or breakers.
- Look for the breaker marked “AC” and ensure it’s in the “on” position. If it’s overloaded, the lever will be in the "off" position.
- Quickly transfer the switch back to the “on” position. If it instantaneously flips again, don’t touch it and get in touch with us at 972-332-1028. A breaker that keeps flipping may indicate your home has an electrical issue.
Incorrect Thermostat Settings
If your thermostat isn’t signaling your equipment to work, it won’t activate.
The main point is making sure it’s set to “cool” and not “heat.” Otherwise your air conditioning will probably not turn on. You could also get heated air blowing from vents being the furnace is running instead.
If you rely on a regular thermostat:
- Replace the batteries if the screen is clear. If the monitor is displaying scrambled letters, buy a new thermostat.
- Check the correct setting is on the display. If you can’t change it, override it by lowering the temperature and pushing the “hold” button. This will force your AC to work if programming is wrong.
- Attempt to set the thermostat 5 degrees cooler than the space’s temperature. Your AC won’t work if the thermostat is identical to the house’s temperature.
Once your thermostat is set correctly, you should begin getting cold air promptly.
If you rely on a smart thermostat, including ones manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for assistance. If it still won’t work, call us at 972-332-1028 for support.
Shut-Down Switch
Your air conditioner usually has a shut-off device around its condenser. This device is commonly in a metal box hung on your house. If your air conditioner has recently been repaired, the lever may have unintentionally been turned off.
Blocked Condensate Drain Pan 
Condensate drain pans hold the surplus water your equipment pulls from the air. This pan can be found either under or within your furnace or air handler.
When there’s an obstruction or clogged drain, water can become concentrated and initiate a safety feature to switch off your unit.
If your pan involves a PVC pipe or drain, you can drain the extra liquid with a custom pan-cleaning tab. You can purchase these tablets at a home improvement or hardware retailer.
If your pan includes a pump, look for the float switch. If the mechanism is “up” and there’s moisture in the pan, you may need to get a new pump. Contact us at 972-332-1028 for assistance.
2. AC Blows Warm Air
If your air conditioner is going but not delivering cold air, its airflow might be clogged. Or it may not have enough refrigerant.
Blocked Airflow
Your system’s airflow can be restricted by a blocked air filter or dirty condenser.
How to Put in a New Your Air Filter
A dusty filter can cause countless issues, including:
- Reduced comfort
- Frozen refrigerant lines or evaporator coil
- Uneven cooling
- Increased electricity bills
- Causing your system to wear out sooner
We recommend changing flat filters every four weeks, and pleated filters every three months.
If you can’t remember when you last replaced your filter, switch off your AC completely and take 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.
Tilt the filter up to the light. If you can’t see any light, you need to buy a new filter.
4 Steps to Cleaning Your AC Equipment
Weeds, grass and leaves can block your condensing system. This could reduce its airflow, make it less energy efficient and affect your comfort. Here’s a method you can follow to get your equipment operating properly again.
- Switch off the electrical current fully at the breaker or outdoor lever.
- Clear greenery rubbish around the air conditioner. Once you’ve cleared all the clutter within a two-foot range, you can use a soft brush or vacuum to carefully remove dust from the unit’s fins. Misshapen fins can also hurt capability.
- Use a hose nozzle to slowly clean the fins from inside the unit. Make sure to avoid getting moisture on the fan motor.
- Turn the power back on.
Not Enough Refrigerant
When cooling equipment doesn’t have adequate refrigerant, they’ll struggle to remove heat and humidity from your house.
Here are a couple of indications that your system is seeping refrigerant:
- It takes too long to lower the temperature in your residence and you’re constantly turning down the thermostat.
- Cooling coming through the vents isn’t as cold as it should be.
- You’re noticing fizzing or gurgling racket when the air conditioning is on.
- Your evaporator coil is icy on account of having an issue taking on humidity.
Think your unit is seeping refrigerant? You need a certified heating and cooling service specialist to repair the leak and refill the correct level of refrigerant in your system. Reach us at 972-332-1028 for assistance.
3. AC Not Blowing Enough Air
When it feels like you’re not having enough cool air, there’s potentially a blockage or disconnection within your cooling unit.
- The beginning stage is looking at your air filter. Get a new one if it’s soiled.
- Make sure the vents are open throughout your home.
- If you’re still not getting enough cold air, you should have your ductwork checked by a expert like Bon Air Service Company. Your duct system could need to be repaired or reconnected in difficult spots like your attic, basement or crawl space.
